Looks like the Eachine monitor lets you select a specific antenna and I had it set to antenna A, what a dummy. I vaguely recall noticing that when I first got this monitor, I would have immediately set it to diversity because there's usually no good reason for any other mode. I definitely remember seeing it switching between antennas at some point, but that was quite a while ago and I hardly ever use it. So I guess somewhere along the line that setting got changed - maybe when my little nephew was using it last week. Yes, FBWB with a low-altitude limit means even a 5 year old newbie can have fun with a fast plane and not cause the plane owner any stress :)
Really hope FLYSKY has sent you the the top of the line radio from every line they sell. Because you have done more for their sales then the ad department for Flysky for sure. I own two of these radios because of your vids. I upgraded to a Taranis because of fail-safes due to no warning on OSD at the time anyway, not sure if they have fixed it yet.
To prove your point, I want to get me a FS-6X, was sceptical, but I am impressed that it got past 1000m. Being such a cost effective "entry level" radio. I want to get into RC, but need to fiddle with sims before I commit.
I have been out of RC for many years but when saw the price and your use of the Banggood TX my interest was peaked. A am very impressed with the design of your experiment. I thought I was looking at many hundreds of dollars for a new TX as my old one was crap. Leave it to the engineers of Bangggood to produce what we need for another excellent price. Anyway, I have subscribed to your channel. Wish I lived there as have always thought about immigrating there when I was younger. Now 71, I just dream about it. Best wishes from Ft. Worth, Texas and looking forward to more of your videos.
Thank you so much for this video! I’m an avid flyer that started out many many years ago and just recently got back into it because of my grandson! We both have the same radio as yours and I’m grateful that you showed that this radio can be set up to do fail safe with an airplane! And I mind blown this thing actually traveled over 6 miles before it lost signal that is very very far! Keep up the good work I would love to see more of your technological breakthroughs with regards to model airplanes.
12:28 This difference in direction regarding the distance away from home till signal loss phenomenon needs further testing as I recently observed the same thing testing a 2.4ghz radio going through power output settings and it was consistent and happening under completely different RF conditions but the same ratio was noted it seems. What I noticed was as if there was glue on the signal keeping itself attached to the RX but after distance broke the initial constant connection to the RX it became intermittent returning in the return to home direction and I didn't get the signal back well and I remember thinking on the first low Mw output setting jezz this is about a 25% difference relative to each direction where the distance gained got pushed back about 25%. I had the RX on a thin low density RF friendly foam board with a bubble level meter to keep the antennas in a fixed position with my body kept on the same side in both directions, a 6.6v Life battery feeding a switching 5v regulator set at fixed distance to the RX to add it's RF noise to the servo's as is most common in my setups, and two weights on a string to keep the RX antennas at the same height above the ground as the TX was set up at which was height I hold the TX at LOS standing, and check the RX reception at a lower height which makes a surprising difference and showed the RX put just one foot lower at range could lose the signal and not get it back at that height so wonder if the pitching up and down you mentioned had affected your altitude enough to take it out if the fresnel zone. But at that distance in a vast open ideal RF area the huge difference in control range relative to direction should not have occured due to altitude or antenna placement nor moving off to one side slightly on the return leg of the flight. I noticed keeping the RX height constant and antennas level, with my body to the same side holding the RX antenna board, that with each Mw power increase where the increase moving away gave me say a 100 ft gain.. after losing the signal it did not become solid again until perhaps as much as 50ft back returning in the other direction connected to the exponential curve of RF range gained from higher Mw settings as if the increase in power output was reduced moving back towards it consistent with the exponential gain from increasing TX power output settings. Because the point of losing reception was so wide I determined the range testing was flawed for comparing components and was being affected by RF noise perhaps and just a rough estimate of limited value the way I was doing it... but seeing this video makes me want to redo the measurements and see if the first failsafe in one direction is consistent which I marked off to test different TXs. Will use GPS and Google next time and take better notes as going away seemed like a more consistent and measurable distance than the return measurements contradicting the out bound measurements I assumed would be the same. I wish you had just turned around and keep the same return path, but at that distance out over the ocean unless you really moved off to one side or up and down in height the extreme difference in RF reception directions noted should not be caused by that, nor your antenna placement as this phenomenon seems to be more than antenna placement. I always favor return home placement of antennas and this video shows why that's so important, but it may show something else to look for as your setup favors RTH reception IMO. Normally I'd say you GPS was causing this but after seeing this happen on multiple range tests myself I'm baffled by what caused your extreme loss in control range on return to home. Like you said you are an an area that eliminates other 2.4 Ghz RF unless some HAM operator is jamming the frequency and even that should have the same effect in both directions. 17:08 is a possibility I suppose but doubt he noticed your plane and was broadcasting on your frequency. At any rate I've noticed good reception going out to a rather defined distance but after the failsafe not as good coming back so something to look for and see if it happens before getting to that point of failsafe and will test for that next time using different RX's and TX's to try and isolate the observation. Been right in the middle of changing gear and doing LOS range tests where I fly and was disappointed by my results to compare RF modules so really glad you posted this this as going out failsafe happened as expected, but RTH performance was not defined by showing the same type of range reduction... thanks.
Just incredible how far you can go when you don't have to compete against any other floor noise rf..... I have a hard time making it any farther than 5 miles with a high power VHF... but there is tons of people using the same frequencies....Great Job...
Thanks for testing the Flysky i6X! I really like mine! For what it is (a budget radio), it's a great radio. (for me flying out to 1k is a LONG ways!)

29:00 I soldered a miniUSB connector to my FlySky i6 transmitter for power. It's really convenient, USB powerbanks are easy to charge and if you don't have one, you can use OTG on your phone. You can also keep them warm in your pocket. I've found that NiMH's voltage sags significantly in cold weather.
Really awesome experiment! As for the up and down motion of the plane: Two things are happening, the first is that the aircraft tries to keep a set altitude of 100m and secondly it is trying to maintain a fixed airspeed. When the altitude is to high the controller pitches the aircraft down and lowers the altitude but thereby it increases the speed. Now the speed is too fast and it tries to reduce the speed by pitching the aircraft up which causes it to increase in altitude. From what I understand you should be able to get away without using an airspeed sensor and just rely on the IMU and the GPS in order to estimate your airspeed. What could help is adding an airspeed sensor to get the actual aircraft airspeed. Anyway, you make really awesome videos and have gotten me to invest in a flying wing.
I think Arduplane is smarter than that, otherwise all my planes would have this problem. I figured it out later, the throttle slew speed was set too slow, meaning the autopilot could not adjust the throttle position very quickly.
Oh, but i'm surprised pretty much about such good range! I heard some people were saying FlySky is not so good radio and failsave kicks around 500 meters even.
@@cutefoxRC To be honest with you, I had a misfortune and lost the signal at about 300-400m and sadly lost a very expensive drone. I never found it :( But that's part of this hobby. Anyway, I will always love FlySky, my first radio :))
@@groundzonepilot7536 oh, wow, do you know what caused such failure on such short distance? I guess this radio is very vunlerable to interferences? Also, is there any warning about bad signal, or it's silent always?
cute fox there is a radio tower nearby, I assumed it was the cause, but not sure honestly. You do have an “signal strenght indicator” on the radio, but I was using FPV goggles and couldn’t see it on my radio. It was a sad day really lol 😂
10k before first fs! Did not expect that! Wow! The best use that I’ve found for the aomway helical is hangin on the wall in the man cave, cuz it looks cool. The VAS helical rocks. And u rock, thanx for the vid.
The little bit at the end was nice Chris... :) I have one of those Flysky radios too and for cheap, it's damn solid. I also have the same monitor. I wasn't real impressed with the receiver sensitivity but it's nice for watching when the FC is booting up and catching satellites instead of taking goggles off and on. Nice flight! I enjoyed that! Keep 'em coming. It's winter here. Had our first snow already. I need entertainment. LOL!
Really interesting video, thanks Chris. I'm a big fan of the ia6 so am always interested in your videos featuring this radio. In terms of batteries, three reasons to avoid AAs and use Lithium Iron LiFe (not polymer LiPo), 1. Avoids oxidation of the AA cell caps which can lead to poor connection and radio drop out. 2. Self discharge, LiFe remains charged for years, NiMh will self discharge within weeks. 3. LiFe can be fully discharged without penalty. Really interested in Ardu Pilot and all the associated electronics so thank you for sharing. Looking forward to the next instalment. Thanks again.
NiMH can also be fully discharged without penalty, no? Maybe not entirely undamaged, but better compared to a lipo. Personally I fly a couple of times a week at least so self-discharge is not a concern. I don't get why the chemistry inside the battery affects oxidation of the terminals...
You can re-use old wifi dish antennas and use those little antennas as feeds. Any modern wifi gear has pretty insane antennas, especially the outdoor stuff.
Regarding getting less control range on the way back. Think about a doughnut shaped radiation pattern around the receiver antenna. The doughnut is at an angle pointing to the ground when you look at it from the back of the airplane and pointing to the sky when you look at it from the front of the airplane, hence why you got less signal on the way back. This is more clear with the flysky because the receiver antennas are sleeved dipoles which create a flatter doughnut pattern than a sanders style antenna for example. Regarding the signal breakup on the monitor with the patch antenna. This is due that the patch antenna is not circular polarized, so it's not rejecting signal reflections from the ground. Regarding the monitor not switching to the helical antenna from the patch antenna. The patch antenna probably has higher gain than the helical one so the diversity receiver selects the one with the strongest signal. Strongest signal does not mean the best signal in this case, since the helical antenna even with a weaker signal would give you better video since it would reject the signal reflections from the ground and eliminate the breakups. Best would be to use only circular polarized antennas, imho.
A very good test. The _effective_ control range seems about right to me as with exactly the same Tx/Rx combination in a slightly less advantageous area the max range was about 2.7km at about the same AGL . It's a lot shorter in more populated areas though. The vertical "hunting" is quite curious but not being a ardupilot boffin my only suggestion would be a slight throttle speed increase in that mode (and that's probably wrong). Fascinating detail thanks
I believe the pulsing was caused by a mismatch in response time from your flight comp to your ESC. The ESC response time needs to be set to start immediately rather than what’s called a “soft start-up” or something on your ESC programming. (Experienced the same issue a little while back)
Very good call. After thinking on this for a while I realized I had set the "slew rate" for the throttle to a fairly low value, instead of the default of 100%. The slew rate specifies how much the autopilot is allowed to change the throttle in one second. I think I had it at 50% so the outcome would be similar to what you are suggesting. Having said that though, I think the start-up time setting of the ESC applies only to starting from zero, rather than throttle adjustments after it's already spinning.
Informative perhaps just a wee bit long . But very very interesting . Nice you also showed and explained the gear and your opinion / experiences /thoughts . A great flight with the safe return of your aircraft .. Nice work Chris.
Your video has gotten a lot of views really quickly and I have to say it is well deserved. great video. I really like the full explanation of all the gear used and the links. Thanks for taking the time to post the video. learned a lot and that will help on a variety of my projects that include drones and remote controlled cameras etc. Too bad that micro whip antenna for 915MHz is discontinued, I really like the look of that one. Anyways, thanks for sharing. Oh and the bit about the diversity receiver... won't say I have ever done that... not CAN'T say I have ever done that... WON'T say... :-)
I’ve had the fly sky radio for a couple years now and am pleased with the bang for the buck u get it is only 50 bucks but it does a nice job nothing fancy
@@Mansare94 In all honesty, at that price point, even reaching the claimed range is kind of impressive. Not mentioning that it comes bundled with a receiver, which places the radio in an even lower price bracket should that $10 be discounted. But I get what you are saying. I'm out in the middle of nowhere myself, so very little WiFi routers, cordless phones, microwaves and mobile service provider masts that could cause interference. Amazing bang for the bucks, nonetheless...
Wow!! Probably a place where there isn't any type of floor noise at all!! may be a place that don't even have cellphone coverage!!! in that way.. the music on that radio is the only one been played!
Make yourself a 1.5m dish and use the circularly polarised antenna. Probably have to add a boresight to the dish for aiming. That will increase your range considerably.
iforce2D: Your RUclips videos are the best! However, I don't see where you specified the receiver type for your FS-i6X transmitter. Was it a X6B? I have one and need tips on how to connect to the servos on a fixed wing (not multicopter) aircraft to the FS-X6B which has only single pin PWM outputs. Can you help? Thanks. Jim
ia6b, I showed some of the setup near the end 26:36 Servos need a ground, positive voltage (usually 5v), and a signal pin. The first two are the same for all servos, and don't need to come from the receiver. Only the signal lines are unique for each servo. ruclips.net/video/NmXbyLZJqIk/видео.html
I'm willing to bet you're thinking right on the antenna position I believe most recommend one vertical and one horizontal ideally as far out on the wings as possible the less components in the way the better in particular an HD camera and the battery on the nose probably block a lot of RF if you'd tested control going out I bet it would have been better.
A pair of turbowing 2.4ghz amplifiers (one for each antenna output) will have you going considerable distances. I don't know how far my range is as I loose video before coming even close to failsafes but I regularly fly 2 miles out whilst being a mile up over an area of land which has significant RF. There are thousands of routers in the area but also several radio stations, a tv transmitter in the kw power range just 1000ft from where i fly and another tower with other communications on it. My 2 mile out whilst 1 mile up flights are not the limits of my control range, my video is the limiting factor for me.
There is a throttle slew rate parameter or something. I don’t get that throttle pulsing on my Mini Talon. It is a quadplane so there are some differences. My ESC is mounted recessed in the top of the fuselage between the tail fins. Had to put it there otherwise is overheated after about 40km.
Did you notice the little red pull tab on your monitor? That is there so that you can remove the manufacturer's protective cover for their assembly process. Remove the cover.
Yes I noticed it about 2 seconds after I took it out of the box. It's like all the other screens of this type that I have, the colored tab is firmly stuck under the plastic frame and would require disassembly to pull out, and actually doesn't look like a protective covering either. But if it was, why would I want to remove it, I had not even noticed it while using the monitor for two years until you reminded me. I would rather it remains protected and with a slightly matte surface than a glossy shine, it's hard enough to see on a sunny day as it is.
@@iforce2d I have the same unit and found it a bit difficult to remove the protective screen cover as the tab is slightly under the bezel. With a little effort though, I was able to remove it and was pleasantly surprised as to how good the screen looked.
Same here, as I have a 6 channel and a 10 channel radio by FlySky. (I'm new to the hobby, and thought I had a bad radio, so bought the 10 channel for a "back-up" radio. Turns out, that I'm a dummy when it comes to R/C Electronics...And I'm learning quickly just how much I DON'T know!). Haha!
Same boat as you guys. I want to start, but my budget is a bit tight. So no Taranis for me... 😅

That bobbing is most probably from the altitude hold loop or air speed loop (or from the baro or the pitot tube but I doubt it a lot). Increase the P term on one of these and test. If bobbing harder, decrease or try to add in some D (if possible). If decreases, keep pushing the D until starts pulsing the motor again (might do it violently) and decrease a bit from there where it is solid.
the helical has to be aimed pointing at the plane every time i saw it it was aimed up to the right pointing at the sky so it wouldn't have picked up much of anything. have to aim it like a patch, its just slightly better for if you have CP antennas on the transmitter than a patch if its made well.
One thing I found with the FS-IA6B (using a VNA) is the antenna's are very easily knocked out of tune by anything plastic near the driven element. Even sliding them inside some thin stiffener tubes made the VSWR skyrocket, so I leave that section clear and on my aircraft I run one antenna dead horizontal across the plane, and one vertical as the transmitter also has the same configuration inside. I get many KM over mountainous terrain, and the telemetry also holds up well. Also, those Aomway helicals are a joke. They perform worse than a bare SMA pin on it's own, the mismatch at the feedpoint is abysmal and just cannot work. Anyway, another great video, Cheers.
thanks for the info, i also have ia6b just a quick question for fixed wing plane would it be better to have both antenna be horizontal with.. one pointing to tail/nose and another pointing to wings...or...one pointing to wing and one vertical straight up 90°?
The monitor stayed on channel a because you have that channel selected. (i have the same monitor and can see it on the osd at 14:28) . The monitor lets you choose channel a, b or diversity. If it doesnt say diversity in the upper left you arent using it.
Hi grate video again if you hot glue a peir of tie wraps vertically on the fuselage you can then fit the antennas on them. To get the best diversety put one the wrap across the bottom of the fuselage out to the side
That rising and falling beyond horizontal maybe the sea doing the same and the plane is trying to copy of ? Just a thought. I just found your channel and I was impressed ... Just a bit more technical, I subscribed and I'll have a few video's to watch.
G'day from across the pond. Premier or not, I choose what I want to watch. Awesome distance with your antennae like the way they were and in perfect no wind conditions, possibly expect longer flight distance fitted vertically.It would be interesting how far it will get when set up with diversity on and antennas vertical.
allow a bigger derivative error and slower the proportional. i flew planes with no control surfaces, the up and down is when I react to fast on the throttle and it will never straight out, always oscillating. I could smooth it out by a glide decent and very very slowly picking up the throttle until the VS is just a little positive or near 0. after every turn I had to do that to fly straight and level.
The premiere function is super annoying. It spams the subscription feed with videos that you cannot watch. Even worse, it is a video that you could watch because it is already uploaded. But you are artificially restricted to watch it now. Then it will appear a second time in the video feed, when you can finally watch it.
You are not restricted to watch it now... watch it next week :) Having said that though, I do find it annoying that it's there but you can't watch, which is why I set the time to a few minutes away.
I ran this radio setup forever and never knew how bad the response time was when compared to FrSky qx7. Where the Flysky would have high latency at a distance the FrSky was still very responsive.
Great detailed video! I have been using the Flysky i6X for about a year now and always wondered how far I could get my SkyTrainer out. Now I don't have to worry about going out more than 500 yards. Thanks
Long Range systems like the R9M and Crossfire have better penetration and ability to bend around objects. Because the 900MHz frequency is lower than 2.4ghz
15:15 The horizon going up and down. There is an adjustment problem with the PID (proportional integral derivative) controller. en.wikipedia.org/wiki/PID_controller
Yes, I have written many PID controllers myself. Ardupilot has multiple PID loops all working together along with other factors that might influence this such as throttle slew and damping, the trick is to know which of them I might have missed in the 2 hours I have already spent twiddling with adjustments.
My flysky fs th9x has only 200m on the ground and so is my friend Th9x... is even shorter with original antenna and receiver.. In the air the range will extend. In addition, some Tx module of same model gives over 400m on the ground. It depends on your luck. We lost some aircraft due to the shorter range TX module.
@@peterzingler6221 we tested , its the transmitter problem. We use one receiver to test on 3 set of tx module of the same type. 3 different tx module yield different range on same rx . Only one module turn out to be about 400m range...the rest is below 200m ....so I guess its a different batch of plug in module.
clikcbait title 5km.??.. you could with a straight face clashed +22km in that title, but I love that you kept it humble. New Zealand (as I recall) also in general a pretty honest country when looking on the worlds backbone index Transperancy International, the only country that rank higher then NZ was Denmark as I recall.. 1 Denmark 2 New Zealand 3 Singapore. wicked flight, thx for the vid. would you be able to elevate the range with these 2.4Ghz Yagi booster that was quite popular for fx Mavic some years back... quite directional passive amplifying
You may already know this, but I would recommend reading on how these antennas work: helical antennas: en.wikipedia.org/wiki/Helical_antenna Also, the signal does not "bounce" off water at these frequencies. At extremely high frequencies (like 60 GHZ), you can bounce the signal off the water, only if it the water is very smooth (like glass). But as we all know, the ocean is anything but smooth. So at these frequencies, consider the water a giant signal absorber: www.electronicspoint.com/threads/rf-through-water-question.21986/ This is a great article on wireless video transmission: www.datarespons.com/drones-wireless-video/ Cheers from California.
I would consider that a radio that doesn’t failsafe until 90% connection loss is not a good radio. The aircraft flew for many km’s beyond the point it should have failsafed. You proved that on the return part of the flight.
Yes. That's a setting in the flight controller though, not the radio. I could have changed the settings so that there was no short failsafe and the long failsafe was more like 0.5 seconds or something. That would stop the plane from going so far into the non-practical range. Another thing to consider is not all flight requires constant control. A longer failsafe timeout lets an automated waypoint flight continue beyond the range of good manual control, yet still be recallable at any time. This would be useful when doing aerial mapping where the plane flies a grid pattern for an hour or so with no manual input, and an over-zealous failsafe would only cause wasted time and battery by needing to have the RTL cancelled each time, it would probably also mess up the 'lanes' that the plane tracks on to take photos.
Good show man.I am using same batteries for a couple years in my cloned FS-i6x. iRangeX what a great TX for $34 on sale came with a8s-rx.Never had failsafe with the ia6b.Where i fly my quadcopters really noise close to NYC.2 months flying FS-NV-14 Nirvana but still keep a few birds on my i6x love it.
I could not say for sure with Flysky Protocal but i think so.With Nirvana OpenTX you can use long range modules R9M & TBS Crossfire without mods.Just make sure you get full size modules with XT30 for external battery power source.
@@petertothRC-FPVthe only point of getting the nirvana is that I don't have to buy new receivers, I don't want to move away from flysky, and if I would go for long range I would buy the qx7s with R9 for like 175$ it's on sale currently
I trust my Flysky receivers ia6b,ia6c most of all and held out a long time to upgrade my tx since they are that good.I just hope they can fix bugs that Flysky Nirvana has capability to be a top contender for FPV pilots.
Your not wrong and Raglan is an especially beautiful and special place, The irish side of my family were some of the original european settlers there :)
Are those monopoles or dipoles on the receiver? People in the forums are reporting much better signal with the sleeved dipoles (or DIY T-shaped dipole) compared to the 1/4 wavelength monopole.
your transmitter/controller should be tilted forwards towards the rc for better directional signal, ie. the same way it would sit naturally in your hands if you were holding it. You have it pointing to the sky?? While it might not sound legit and necessary, I'm confident you will notice the difference in range. That controller antenna transmits in a cone-like direction from the top of the transmitter, a cone you have pointed to the sky above you in this try. Take it or leave it. Enjoyed the vid, great commentary. Thanks from a fellow kiwi. p.s. the motor is not pulsing , its just responding in variations of torque from the prob as the plane rises and falls gradually and fights the turbulence. Its not doing anything out of the ordinary. :)
There are two antennas in this radio, one in the little stub pointing upward and one horizontally across the handle. Both are sleeve monopole and radiate in a donut shape, so the strongest direction will be perpendicular to both, ie. the direction in which I sent the plane in this test. en.wikipedia.org/wiki/Monopole_antenna#Radiation_pattern Yes, the motor is pulsing as we can clearly hear in the audio. It is about twice as powerful as it needs to be and would have no problem with torque (even if a change in aircraft attitude would cause that). The problem is likely to be that the flight controller is not tuned correctly to adjust for small altitude variations from the target altitude. Although given the amount of time I have spent twiddling with the settings to no avail, I'm also considering it might be changes in air pressure inside the fuselage caused by the slightly different angle of attack (there is an inlet hole at the front on top, and I have not yet covered the barometer with cotton wool.
@@iforce2d ahh ok. thanks for your reply, and it sounds like you have well researched into the situation, I was referring to something like this www.waves.toronto.edu/prof/Balmain/pdffiles/Resonance_cone_power_flow.pdf. I can see you have good finger on the technical pulse :) Interesting about the motors surging aye, I should've had a good listen with the volume up before piping in ;). you know your setup well, hope you get it figured :) As a side note: I was considering a project using GSM cell to control with live feed ultra long distance, which would essentially be a uav really, fun project I thought. sigh, as soon as i have my own workshop :). Happy flying mate.
Hi, awesome video didnt expected it can go that far :D sady u didnt recorded error rate on flysky was waiting on that scene. I managed to reach 4km out in one direction with same flysky but with a quad and yes controls starting to lag, and no more gas in battery to go futher rly... since I love this long range testings, I'm about to reroll on plain. One thing bothering me, u flaying without compass at all? only gps? How do u know which direction are u flaying when image transmission starting to be snowy and u cant rly see terrain below u? only by degress on OSD, u dont have home arrorw? I alwas had problems with damn compases in M8N modules tried few differens versions different sellers... they calibrate well and work accuarte but occasionally can cause glitches and misdirection of home pointing arrow, and u cant realy 100% on that when image gets bad
I showed the compass at 27:26 But planes are assumed to fly forwards, so whatever direction it's moving is assumed to be the direction it's facing. Compass is really only necessary if the plane is not moving forward relative to the ground, eg. in a very strong headwind. Having said that though, I was not flying the plane at all in this video, only the landing, so I did not need to see anything on the OSD really.
Have you tried a otg receiver for your cell phone using the go fpv app? I get good results on DVR with mine.. I'm running dual 6dbi flat blade antennas on mine.
I love this setup looking for something similar. What ESC, Flight Controller, Motor and Prop are you using? Do you need the telemetry radios or are they just for data? eg could you plan the route and just send it?
CP antennas on 5.8G are a complete waste of time for range flying IMO. I always use a Linear on my VTXs and a Pair of Linear Patches on my Diversity Monitor. This gives a wide beam to fly in and hand tracking is realy easy, especially if your monitor has rssi for each antenna. The Flysky did well though I have seen one do well before on a similar test....Dump the CPs.if you want range, there is too much dbi loss with circular.
With an EPO plane, do you really have to mount antennas outside of the fuselage? Do you think that the EPO really effects the radio signal in any measurable value?
No, EPO is pretty much zero concern. Mainly it's the other transmitters that it needs to be separated from, but the further you can get it from any other electronics the better.
Looks like the Eachine monitor lets you select a specific antenna and I had it set to antenna A, what a dummy. I vaguely recall noticing that when I first got this monitor, I would have immediately set it to diversity because there's usually no good reason for any other mode. I definitely remember seeing it switching between antennas at some point, but that was quite a while ago and I hardly ever use it. So I guess somewhere along the line that setting got changed - maybe when my little nephew was using it last week. Yes, FBWB with a low-altitude limit means even a 5 year old newbie can have fun with a fast plane and not cause the plane owner any stress :)
do you know of any fpv / drone clubs in nz
@Koa Stefan ,Dont think anyone cares....

I own two of these radios because of your vids. I upgraded to a Taranis because of fail-safes due to no warning on OSD at the time anyway, not sure if they have fixed it yet.

Worth, Texas and looking forward to more of your videos.
Thank you so much for this video! I’m an avid flyer that started out many many years ago and just recently got back into it because of my grandson!
We both have the same radio as yours and I’m grateful that you showed that this radio can be set up to do fail safe with an airplane!
And I mind blown this thing actually traveled over 6 miles before it lost signal that is very very far!
Keep up the good work I would love to see more of your technological breakthroughs with regards to model airplanes.
The radio is not doing the failsafe, it's the autopilot doing that.
A great video and explanations of how it was done! Have to say I'm impressed how far a cheap radio worked.
Nice detailed explanation and range test. It has been a while.
12:28 This difference in direction regarding the distance away from home till signal loss phenomenon needs further testing as I recently observed the same thing testing a 2.4ghz radio going through power output settings and it was consistent and happening under completely different RF conditions but the same ratio was noted it seems. What I noticed was as if there was glue on the signal keeping itself attached to the RX but after distance broke the initial constant connection to the RX it became intermittent returning in the return to home direction and I didn't get the signal back well and I remember thinking on the first low Mw output setting jezz this is about a 25% difference relative to each direction where the distance gained got pushed back about 25%.
I had the RX on a thin low density RF friendly foam board with a bubble level meter to keep the antennas in a fixed position with my body kept on the same side in both directions, a 6.6v Life battery feeding a switching 5v regulator set at fixed distance to the RX to add it's RF noise to the servo's as is most common in my setups, and two weights on a string to keep the RX antennas at the same height above the ground as the TX was set up at which was height I hold the TX at LOS standing, and check the RX reception at a lower height which makes a surprising difference and showed the RX put just one foot lower at range could lose the signal and not get it back at that height so wonder if the pitching up and down you mentioned had affected your altitude enough to take it out if the fresnel zone. But at that distance in a vast open ideal RF area the huge difference in control range relative to direction should not have occured due to altitude or antenna placement nor moving off to one side slightly on the return leg of the flight.
I noticed keeping the RX height constant and antennas level, with my body to the same side holding the RX antenna board, that with each Mw power increase where the increase moving away gave me say a 100 ft gain.. after losing the signal it did not become solid again until perhaps as much as 50ft back returning in the other direction connected to the exponential curve of RF range gained from higher Mw settings as if the increase in power output was reduced moving back towards it consistent with the exponential gain from increasing TX power output settings.
Because the point of losing reception was so wide I determined the range testing was flawed for comparing components and was being affected by RF noise perhaps and just a rough estimate of limited value the way I was doing it... but seeing this video makes me want to redo the measurements and see if the first failsafe in one direction is consistent which I marked off to test different TXs. Will use GPS and Google next time and take better notes as going away seemed like a more consistent and measurable distance than the return measurements contradicting the out bound measurements I assumed would be the same.
I wish you had just turned around and keep the same return path, but at that distance out over the ocean unless you really moved off to one side or up and down in height the extreme difference in RF reception directions noted should not be caused by that, nor your antenna placement as this phenomenon seems to be more than antenna placement. I always favor return home placement of antennas and this video shows why that's so important, but it may show something else to look for as your setup favors RTH reception IMO. Normally I'd say you GPS was causing this but after seeing this happen on multiple range tests myself I'm baffled by what caused your extreme loss in control range on return to home. Like you said you are an an area that eliminates other 2.4 Ghz RF unless some HAM operator is jamming the frequency and even that should have the same effect in both directions. 17:08 is a possibility I suppose but doubt he noticed your plane and was broadcasting on your frequency. At any rate I've noticed good reception going out to a rather defined distance but after the failsafe not as good coming back so something to look for and see if it happens before getting to that point of failsafe and will test for that next time using different RX's and TX's to try and isolate the observation.
Been right in the middle of changing gear and doing LOS range tests where I fly and was disappointed by my results to compare RF modules so really glad you posted this this as going out failsafe happened as expected, but RTH performance was not defined by showing the same type of range reduction... thanks.
Just incredible how far you can go when you don't have to compete against any other floor noise rf..... I have a hard time making it any farther than 5 miles with a high power VHF... but there is tons of people using the same frequencies....Great Job...
Thanks for testing the Flysky i6X! I really like mine! For what it is (a budget radio), it's a great radio. (for me flying out to 1k is a LONG ways!)
29:00 I soldered a miniUSB connector to my FlySky i6 transmitter for power. It's really convenient, USB powerbanks are easy to charge and if you don't have one, you can use OTG on your phone. You can also keep them warm in your pocket. I've found that NiMH's voltage sags significantly in cold weather.
Really awesome experiment! As for the up and down motion of the plane: Two things are happening, the first is that the aircraft tries to keep a set altitude of 100m and secondly it is trying to maintain a fixed airspeed. When the altitude is to high the controller pitches the aircraft down and lowers the altitude but thereby it increases the speed. Now the speed is too fast and it tries to reduce the speed by pitching the aircraft up which causes it to increase in altitude. From what I understand you should be able to get away without using an airspeed sensor and just rely on the IMU and the GPS in order to estimate your airspeed. What could help is adding an airspeed sensor to get the actual aircraft airspeed. Anyway, you make really awesome videos and have gotten me to invest in a flying wing.
I think Arduplane is smarter than that, otherwise all my planes would have this problem. I figured it out later, the throttle slew speed was set too slow, meaning the autopilot could not adjust the throttle position very quickly.
Put a great big yagi and 2w booster on the flysky and see how far you can get!!
lol it might not come back :)
Dead birds.....
Holy flysky! I'm not gonna sale/giveaway my one ever after watching this
I'm not surprised at all. Fly Sky is my first radio and it proved to be just awesome in the past 2-3 years now.
Oh, but i'm surprised pretty much about such good range! I heard some people were saying FlySky is not so good radio and failsave kicks around 500 meters even.
@@cutefoxRC To be honest with you, I had a misfortune and lost the signal at about 300-400m and sadly lost a very expensive drone. I never found it :( But that's part of this hobby. Anyway, I will always love FlySky, my first radio :))
@@groundzonepilot7536 oh, wow, do you know what caused such failure on such short distance? I guess this radio is very vunlerable to interferences? Also, is there any warning about bad signal, or it's silent always?
cute fox there is a radio tower nearby, I assumed it was the cause, but not sure honestly. You do have an “signal strenght indicator” on the radio, but I was using FPV goggles and couldn’t see it on my radio. It was a sad day really lol 😂
Have this Transmitter too and the range is great! Very nice Radio
10k before first fs! Did not expect that! Wow! The best use that I’ve found for the aomway helical is hangin on the wall in the man cave, cuz it looks cool. The VAS helical rocks. And u rock, thanx for the vid.
The little bit at the end was nice Chris... :) I have one of those Flysky radios too and for cheap, it's damn solid. I also have the same monitor. I wasn't real impressed with the receiver sensitivity but it's nice for watching when the FC is booting up and catching satellites instead of taking goggles off and on. Nice flight! I enjoyed that! Keep 'em coming. It's winter here. Had our first snow already. I need entertainment. LOL!
Love it, that was ballsy. The antenna is (I think) a spiral antenna like the Axii/ Truerc singularity range.
I really like the stand/holder you made. I use a mobility scooter and have been wondering how to mount my transmitters to the scooter. Now I know!
Really interesting video, thanks Chris. I'm a big fan of the ia6 so am always interested in your videos featuring this radio. In terms of batteries, three reasons to avoid AAs and use Lithium Iron LiFe (not polymer LiPo), 1. Avoids oxidation of the AA cell caps which can lead to poor connection and radio drop out. 2. Self discharge, LiFe remains charged for years, NiMh will self discharge within weeks. 3. LiFe can be fully discharged without penalty.
Really interested in Ardu Pilot and all the associated electronics so thank you for sharing. Looking forward to the next instalment. Thanks again.
NiMH can also be fully discharged without penalty, no? Maybe not entirely undamaged, but better compared to a lipo. Personally I fly a couple of times a week at least so self-discharge is not a concern. I don't get why the chemistry inside the battery affects oxidation of the terminals...
You can re-use old wifi dish antennas and use those little antennas as feeds. Any modern wifi gear has pretty insane antennas, especially the outdoor stuff.
Regarding getting less control range on the way back. Think about a doughnut shaped radiation pattern around the receiver antenna. The doughnut is at an angle pointing to the ground when you look at it from the back of the airplane and pointing to the sky when you look at it from the front of the airplane, hence why you got less signal on the way back. This is more clear with the flysky because the receiver antennas are sleeved dipoles which create a flatter doughnut pattern than a sanders style antenna for example.
Regarding the signal breakup on the monitor with the patch antenna. This is due that the patch antenna is not circular polarized, so it's not rejecting signal reflections from the ground.
Regarding the monitor not switching to the helical antenna from the patch antenna. The patch antenna probably has higher gain than the helical one so the diversity receiver selects the one with the strongest signal. Strongest signal does not mean the best signal in this case, since the helical antenna even with a weaker signal would give you better video since it would reject the signal reflections from the ground and eliminate the breakups. Best would be to use only circular polarized antennas, imho.
A very good test. The _effective_ control range seems about right to me as with exactly the same Tx/Rx combination in a slightly less advantageous area the max range was about 2.7km at about the same AGL . It's a lot shorter in more populated areas though. The vertical "hunting" is quite curious but not being a ardupilot boffin my only suggestion would be a slight throttle speed increase in that mode (and that's probably wrong).
Fascinating detail thanks
I believe the pulsing was caused by a mismatch in response time from your flight comp to your ESC. The ESC response time needs to be set to start immediately rather than what’s called a “soft start-up” or something on your ESC programming. (Experienced the same issue a little while back)
Very good call. After thinking on this for a while I realized I had set the "slew rate" for the throttle to a fairly low value, instead of the default of 100%. The slew rate specifies how much the autopilot is allowed to change the throttle in one second. I think I had it at 50% so the outcome would be similar to what you are suggesting. Having said that though, I think the start-up time setting of the ESC applies only to starting from zero, rather than throttle adjustments after it's already spinning.
that is exactly i wanted to test but i didn't have enough resources to go safe. Thanks Bruh,, you'r awesome
Keep in mind it will not work so well in a city.
@@iforce2d Got it... Thanks man..
Hello. I live in a Canadian city....it looks much, much nicer there...especially the fact that all your water isn’t frozen.....:)
Informative perhaps just a wee bit long . But very very interesting . Nice you also showed and explained the gear and your opinion / experiences /thoughts . A great flight with the safe return of your aircraft .. Nice work Chris.
Thankyou. That was most helpful. I'm all out for range so this applies quite well.
If you want serious range you'd probably be better of with a lower frequency like 900MHz, or maybe a bit better spec 2.4GHz like the FrSky Taranis.
Your video has gotten a lot of views really quickly and I have to say it is well deserved. great video. I really like the full explanation of all the gear used and the links. Thanks for taking the time to post the video. learned a lot and that will help on a variety of my projects that include drones and remote controlled cameras etc. Too bad that micro whip antenna for 915MHz is discontinued, I really like the look of that one. Anyways, thanks for sharing. Oh and the bit about the diversity receiver... won't say I have ever done that... not CAN'T say I have ever done that... WON'T say... :-)
I’ve had the fly sky radio for a couple years now and am pleased with the bang for the buck u get it is only 50 bucks but it does a nice job nothing fancy
But the radio is rated for 300-600m?
Damn, I'm even more impressed... They call it a budget radio.
Interference on the 2.4 band is massive though so being where he is it's not surprising that it gets a lot further away.
@@Mansare94 In all honesty, at that price point, even reaching the claimed range is kind of impressive. Not mentioning that it comes bundled with a receiver, which places the radio in an even lower price bracket should that $10 be discounted. But I get what you are saying. I'm out in the middle of nowhere myself, so very little WiFi routers, cordless phones, microwaves and mobile service provider masts that could cause interference.
Amazing bang for the bucks, nonetheless...
Actually really good mate. Thanks for that
Love those cows on approach!
Nice video, thanks for explain and presentations. Appreciate it 👍
I love this radio, low latency, light weight, thin, great range and great price. I just prefer my taranis.
Wow!! Probably a place where there isn't any type of floor noise at all!! may be a place that don't even have cellphone coverage!!! in that way.. the music on that radio is the only one been played!
Make yourself a 1.5m dish and use the circularly polarised antenna. Probably have to add a boresight to the dish for aiming. That will increase your range considerably.
or just use a 3g dongle on board.
iforce2D: Your RUclips videos are the best!
However, I don't see where you specified the receiver type for your FS-i6X transmitter. Was it a X6B?
I have one and need tips on how to connect to the servos on a fixed wing (not multicopter) aircraft to the FS-X6B which has only single pin PWM outputs.
Can you help? Thanks. Jim
ia6b, I showed some of the setup near the end 26:36
Servos need a ground, positive voltage (usually 5v), and a signal pin. The first two are the same for all servos, and don't need to come from the receiver. Only the signal lines are unique for each servo.
ruclips.net/video/NmXbyLZJqIk/видео.html
I'm willing to bet you're thinking right on the antenna position I believe most recommend one vertical and one horizontal ideally as far out on the wings as possible the less components in the way the better in particular an HD camera and the battery on the nose probably block a lot of RF if you'd tested control going out I bet it would have been better.
A pair of turbowing 2.4ghz amplifiers (one for each antenna output) will have you going considerable distances.
I don't know how far my range is as I loose video before coming even close to failsafes but I regularly fly 2 miles out whilst being a mile up over an area of land which has significant RF.
There are thousands of routers in the area but also several radio stations, a tv transmitter in the kw power range just 1000ft from where i fly and another tower with other communications on it.
My 2 mile out whilst 1 mile up flights are not the limits of my control range, my video is the limiting factor for me.
The Aomway helicals (and patches) are indeed crap.
I was just reminded that there is an 'input source' selection on that monitor which lets you use A, B, or diversity. And I had it on A..... genius.
Great video, I hope some day you could explain the setup of the omnibus and arduplane (mission planner) so I can set it up for my plane.
Plenty of videos about that here:
ruclips.net/video/twW9CaRlj-U/видео.html
Maybe see the "setup steps for flying wing" one.
There is a throttle slew rate parameter or something. I don’t get that throttle pulsing on my Mini Talon. It is a quadplane so there are some differences. My ESC is mounted recessed in the top of the fuselage between the tail fins. Had to put it there otherwise is overheated after about 40km.
i would suggest with regards to the porpoising, increase your cruise throttle
Did you notice the little red pull tab on your monitor? That is there so that you can remove the manufacturer's protective cover for their assembly process. Remove the cover.
Yes I noticed it about 2 seconds after I took it out of the box. It's like all the other screens of this type that I have, the colored tab is firmly stuck under the plastic frame and would require disassembly to pull out, and actually doesn't look like a protective covering either. But if it was, why would I want to remove it, I had not even noticed it while using the monitor for two years until you reminded me. I would rather it remains protected and with a slightly matte surface than a glossy shine, it's hard enough to see on a sunny day as it is.
@@iforce2d I have the same unit and found it a bit difficult to remove the protective screen cover as the tab is slightly under the bezel. With a little effort though, I was able to remove it and was pleasantly surprised as to how good the screen looked.
This is the same radio I have been using since my start of RC hobby. I'm too poor to afford anything fancy.
Same here, as I have a 6 channel and a 10 channel radio by FlySky. (I'm new to the hobby, and thought I had a bad radio, so bought the 10 channel for a "back-up" radio. Turns out, that I'm a dummy when it comes to R/C Electronics...And I'm learning quickly just how much I DON'T know!). Haha!
Same boat as you guys. I want to start, but my budget is a bit tight. So no Taranis for me... 😅
That bobbing is most probably from the altitude hold loop or air speed loop (or from the baro or the pitot tube but I doubt it a lot).
Increase the P term on one of these and test. If bobbing harder, decrease or try to add in some D (if possible). If decreases, keep pushing the D until starts pulsing the motor again (might do it violently) and decrease a bit from there where it is solid.
Pașca Alexandru “pitot rube!?!?” 😧 barometer?!?!🥴 maybe the nonsmoking sign was on in the cabin & causing some fluttering of the flugenbongle🤔 (😄)
Really interesting! Thank you and great details so i can get parts too.
the helical has to be aimed pointing at the plane every time i saw it it was aimed up to the right pointing at the sky so it wouldn't have picked up much of anything. have to aim it like a patch, its just slightly better for if you have CP antennas on the transmitter than a patch if its made well.
Yes, I moved it at some point, but the whole way out it was pointing correctly
One thing I found with the FS-IA6B (using a VNA) is the antenna's are very easily knocked out of tune by anything plastic near the driven element. Even sliding them inside
some thin stiffener tubes made the VSWR skyrocket, so I leave that section clear and on my aircraft I run one antenna dead horizontal across the plane, and one vertical
as the transmitter also has the same configuration inside. I get many KM over mountainous terrain, and the telemetry also holds up well.
Also, those Aomway helicals are a joke. They perform worse than a bare SMA pin on it's own, the mismatch at the feedpoint is abysmal and just cannot work.
Anyway, another great video, Cheers.
thanks for the info, i also have ia6b just a quick question for fixed wing plane would it be better to have both antenna be horizontal with.. one pointing to tail/nose and another pointing to wings...or...one pointing to wing and one vertical straight up 90°?
The monitor stayed on channel a because you have that channel selected. (i have the same monitor and can see it on the osd at 14:28) . The monitor lets you choose channel a, b or diversity. If it doesnt say diversity in the upper left you arent using it.
oh shit... I didn't even know that, now I look stupid.
@@iforce2d no worries. The only reason I keyed in on it was I did the exact same thing when I got mine.
Diversity sure would flip quite a bit when it is near.
Hi grate video again if you hot glue a peir of tie wraps vertically on the fuselage you can then fit the antennas on them. To get the best diversety put one the wrap across the bottom of the fuselage out to the side
That rising and falling beyond horizontal maybe the sea doing the same and the plane is trying to copy of ? Just a thought. I just found your channel and I was impressed ... Just a bit more technical, I subscribed and I'll have a few video's to watch.
G'day from across the pond. Premier or not, I choose what I want to watch. Awesome distance with your antennae like the way they were and in perfect no wind conditions, possibly expect longer flight distance fitted vertically.It would be interesting how far it will get when set up with diversity on and antennas vertical.
Nice to see someone else using Kdenlive for YT video editing :)
Cool video!
Great info and very entertaining too. The MT looks well dialed in for some distance flying. Shame you're not nearer us in Hawks Bay
The cattle aren't even vaguely perturbed!
great job
allow a bigger derivative error and slower the proportional. i flew planes with no control surfaces, the up and down is when I react to fast on the throttle and it will never straight out, always oscillating. I could smooth it out by a glide decent and very very slowly picking up the throttle until the VS is just a little positive or near 0. after every turn I had to do that to fly straight and level.
Yeah I think this was the same thing. I managed to improve it by changing the throttle slew speed, ie. how fast it's allowed to change throttle.
The premiere function is super annoying. It spams the subscription feed with videos that you cannot watch. Even worse, it is a video that you could watch because it is already uploaded. But you are artificially restricted to watch it now. Then it will appear a second time in the video feed, when you can finally watch it.
You are not restricted to watch it now... watch it next week :) Having said that though, I do find it annoying that it's there but you can't watch, which is why I set the time to a few minutes away.
I ran this radio setup forever and never knew how bad the response time was when compared to FrSky qx7. Where the Flysky would have high latency at a distance the FrSky was still very responsive.
Maybe you need to increase the pitch I value
Nice quiet place to live.
Great detailed video! I have been using the Flysky i6X for about a year now and always wondered how far I could get my SkyTrainer out. Now I don't have to worry about going out more than 500 yards. Thanks
Long Range systems like the R9M and Crossfire have better penetration and ability to bend around objects. Because the 900MHz frequency is lower than 2.4ghz
bend LOL
Very interesting, great video I really learned some thing.
you can modify the firmware on the flysky i6 transmitter. just to activate 10 channels for the controls
yes ruclips.net/video/eaj0M218HSM/видео.html
15:15 The horizon going up and down.
There is an adjustment problem with the PID (proportional integral derivative) controller.
en.wikipedia.org/wiki/PID_controller
Yes, I have written many PID controllers myself. Ardupilot has multiple PID loops all working together along with other factors that might influence this such as throttle slew and damping, the trick is to know which of them I might have missed in the 2 hours I have already spent twiddling with adjustments.
My flysky fs th9x has only 200m on the ground and so is my friend Th9x... is even shorter with original antenna and receiver.. In the air the range will extend.
In addition, some Tx module of same model gives over 400m on the ground. It depends on your luck. We lost some aircraft due to the shorter range TX module.
It doesn't depend on luck. Get the right receiver and you will get at least 1km. Fs ia6b receiver in this case
@@peterzingler6221 we tested , its the transmitter problem. We use one receiver to test on 3 set of tx module of the same type. 3 different tx module yield different range on same rx . Only one module turn out to be about 400m range...the rest is below 200m ....so I guess its a different batch of plug in module.
Nice!
Maybe it done because no intervention from other 2.4GHz radio
Next time you need on-board dvr to record it with osd
clikcbait title 5km.??.. you could with a straight face clashed +22km in that title, but I love that you kept it humble.
New Zealand (as I recall) also in general a pretty honest country when looking on the worlds backbone index Transperancy International, the only country that rank higher then NZ was Denmark as I recall..
1 Denmark
2 New Zealand
3 Singapore.
wicked flight, thx for the vid.
would you be able to elevate the range with these 2.4Ghz Yagi booster that was quite popular for fx Mavic some years back... quite directional passive amplifying
You may already know this, but I would recommend reading on how these antennas work: helical antennas: en.wikipedia.org/wiki/Helical_antenna Also, the signal does not "bounce" off water at these frequencies. At extremely high frequencies (like 60 GHZ), you can bounce the signal off the water, only if it the water is very smooth (like glass). But as we all know, the ocean is anything but smooth. So at these frequencies, consider the water a giant signal absorber: www.electronicspoint.com/threads/rf-through-water-question.21986/ This is a great article on wireless video transmission: www.datarespons.com/drones-wireless-video/ Cheers from California.
What type of battery were you using in the AC..... that’s awesome!!
Lipo battery. Hour long flights are not uncommon for this size of plane, check this out: ruclips.net/video/cLH-1raYA6A/видео.html
I would consider that a radio that doesn’t failsafe until 90% connection loss is not a good radio. The aircraft flew for many km’s beyond the point it should have failsafed. You proved that on the return part of the flight.
Yes. That's a setting in the flight controller though, not the radio. I could have changed the settings so that there was no short failsafe and the long failsafe was more like 0.5 seconds or something. That would stop the plane from going so far into the non-practical range.
Another thing to consider is not all flight requires constant control. A longer failsafe timeout lets an automated waypoint flight continue beyond the range of good manual control, yet still be recallable at any time. This would be useful when doing aerial mapping where the plane flies a grid pattern for an hour or so with no manual input, and an over-zealous failsafe would only cause wasted time and battery by needing to have the RTL cancelled each time, it would probably also mess up the 'lanes' that the plane tracks on to take photos.
Good show man.I am using same batteries for a couple years in my cloned FS-i6x. iRangeX what a great TX for $34 on sale came with a8s-rx.Never had failsafe with the ia6b.Where i fly my quadcopters really noise close to NYC.2 months flying FS-NV-14 Nirvana but still keep a few birds on my i6x love it.
Does the nv14 has a better reception than the fs i6x? I want to upgrade my cheap fs i6x to the nirvana
I could not say for sure with Flysky Protocal but i think so.With Nirvana OpenTX you can use long range modules R9M & TBS Crossfire without mods.Just make sure you get full size modules with XT30 for external battery power source.
@@petertothRC-FPVthe only point of getting the nirvana is that I don't have to buy new receivers, I don't want to move away from flysky, and if I would go for long range I would buy the qx7s with R9 for like 175$ it's on sale currently
I trust my Flysky receivers ia6b,ia6c most of all and held out a long time to upgrade my tx since they are that good.I just hope they can fix bugs that Flysky Nirvana has capability to be a top contender for FPV pilots.
What were all those surfers planning to do on such a callm day? (LOL)
Yeah I was thinking that too, maybe they just go there every weekend regardless
Get away from the wife.
It's where boys go to gossip
This was very interesting (also impressive and very informative) man, thanks for sharing! You've got a new subscriber :O)
Such a Beautiful Country, New Zealand is where I have 5 cousins, all fine people and families..
Your not wrong and Raglan is an especially beautiful and special place, The irish side of my family were some of the original european settlers there :)
yep reducing your data rate will help with range 9600 would be a good compromise
great video and explanations good advice.thank you
Nice flying location! The pitching oscillation might be to do with the altitude PIDs rather than the pitch PIDs? :D
Are those monopoles or dipoles on the receiver? People in the forums are reporting much better signal with the sleeved dipoles (or DIY T-shaped dipole) compared to the 1/4 wavelength monopole.
Monopoles with a sleeve balun I think.
@@iforce2d yup
your transmitter/controller should be tilted forwards towards the rc for better directional signal, ie. the same way it would sit naturally in your hands if you were holding it. You have it pointing to the sky?? While it might not sound legit and necessary, I'm confident you will notice the difference in range. That controller antenna transmits in a cone-like direction from the top of the transmitter, a cone you have pointed to the sky above you in this try. Take it or leave it. Enjoyed the vid, great commentary. Thanks from a fellow kiwi. p.s. the motor is not pulsing , its just responding in variations of torque from the prob as the plane rises and falls gradually and fights the turbulence. Its not doing anything out of the ordinary. :)
There are two antennas in this radio, one in the little stub pointing upward and one horizontally across the handle. Both are sleeve monopole and radiate in a donut shape, so the strongest direction will be perpendicular to both, ie. the direction in which I sent the plane in this test.
en.wikipedia.org/wiki/Monopole_antenna#Radiation_pattern
Yes, the motor is pulsing as we can clearly hear in the audio. It is about twice as powerful as it needs to be and would have no problem with torque (even if a change in aircraft attitude would cause that). The problem is likely to be that the flight controller is not tuned correctly to adjust for small altitude variations from the target altitude. Although given the amount of time I have spent twiddling with the settings to no avail, I'm also considering it might be changes in air pressure inside the fuselage caused by the slightly different angle of attack (there is an inlet hole at the front on top, and I have not yet covered the barometer with cotton wool.
@@iforce2d ahh ok. thanks for your reply, and it sounds like you have well researched into the situation, I was referring to something like this www.waves.toronto.edu/prof/Balmain/pdffiles/Resonance_cone_power_flow.pdf. I can see you have good finger on the technical pulse :) Interesting about the motors surging aye, I should've had a good listen with the volume up before piping in ;). you know your setup well, hope you get it figured :) As a side note: I was considering a project using GSM cell to control with live feed ultra long distance, which would essentially be a uav really, fun project I thought. sigh, as soon as i have my own workshop :). Happy flying mate.
Hi, awesome video didnt expected it can go that far :D sady u didnt recorded error rate on flysky was waiting on that scene. I managed to reach 4km out in one direction with same flysky but with a quad and yes controls starting to lag, and no more gas in battery to go futher rly... since I love this long range testings, I'm about to reroll on plain.
One thing bothering me, u flaying without compass at all? only gps? How do u know which direction are u flaying when image transmission starting to be snowy and u cant rly see terrain below u? only by degress on OSD, u dont have home arrorw?
I alwas had problems with damn compases in M8N modules tried few differens versions different sellers... they calibrate well and work accuarte but occasionally can cause glitches and misdirection of home pointing arrow, and u cant realy 100% on that when image gets bad
I showed the compass at 27:26
But planes are assumed to fly forwards, so whatever direction it's moving is assumed to be the direction it's facing. Compass is really only necessary if the plane is not moving forward relative to the ground, eg. in a very strong headwind.
Having said that though, I was not flying the plane at all in this video, only the landing, so I did not need to see anything on the OSD really.
I have an rc sailboat, I want it to have a great range. Can you recommend a transmitter and receiver to achieve a very long range.
works. nice
Have you tried a otg receiver for your cell phone using the go fpv app? I get good results on DVR with mine.. I'm running dual 6dbi flat blade antennas on mine.
I love this setup looking for something similar. What ESC, Flight Controller, Motor and Prop are you using? Do you need the telemetry radios or are they just for data? eg could you plan the route and just send it?
in water the OEM waves is reflected more easily
Very nice. A couple of mistakes but you do all right - keep it up.
Take care to note that from that flying location, you are inside the 4k radius of Raglan
Nice video with a lot of info. Thanks!
CP antennas on 5.8G are a complete waste of time for range flying IMO. I always use a Linear on my VTXs and a Pair of Linear Patches on my Diversity Monitor. This gives a wide beam to fly in and hand tracking is realy easy, especially if your monitor has rssi for each antenna.
The Flysky did well though I have seen one do well before on a similar test....Dump the CPs.if you want range, there is too much dbi loss with circular.
Great Video mate 👍 Very helpful. Thanks
I dont have a clue about the tech stuff. Still enjoyed a well put together video, good on ya mate.
With an EPO plane, do you really have to mount antennas outside of the fuselage? Do you think that the EPO really effects the radio signal in any measurable value?
No, EPO is pretty much zero concern. Mainly it's the other transmitters that it needs to be separated from, but the further you can get it from any other electronics the better.
Awesome video, well done on the setup! Are you ever going to do a similar test with frsky?
Probably not at this rate :)
cool setup! I am going to start playing around with 900mhz
