Excellent review, specially the tip about charging the battery before weighing.
It’s easy enough to calculate the extra weight, so measuring batteries uncharged isn’t a problem. You just enter the number of electrons that are added during charging into your calculator, then multiply that by the weight of each electron (in grams), and you’ve got it. Ps, most people ignore the negative weight of the filled spots in valence rings, mainly because physicists are still not sure how much vacancies don’t weigh.
@@Reach41 which pretty much equals 0
A fully charged 1000000mah 4s battery would weigh 5.04x10^-10 kg more or 0.00000000000504 g more.
@@bputra13 Well, that’s one problem solved! Knowing the exact increase in weight should allow Chris to better locate the battery for CG. 😅
@@Reach41 I REALLY appreciate your input on measuring the battery weight before & after charging. I stopped using a bathroom scale, because believe it or not......electrons don't weigh very much!!! Shocker, isn't it?? No pun intended. Any weigh, (pun intended) i have purchased a more accurate scale, and do the measurement in a vacuum. I'm zeroing in on the weight per electron now. ; )
@@bputra13 That's a lot!, now I am adjusting elevator trim as the electrons get eating up as flight progresses. 🤓
Really enjoyed this, was entertained all the way through. One of my favorite FPV planes, she is the long distance champion.
You can use UHU por like a contact adhesive as you have done and just use it like a "normal" glue. In other words don't let the two surfaces become tacky with a 5 minute wait - glue "wet". That way you can mate two friction surfaces without getting stuck. I think Mr Newton does it as well. I much prefer it to Gorilla Glue.
You have me wanting one, even though I have 2 gliders, an old 28” piper cub kit and 1 other in the build process...and 4 or 5 more in the rafters waiting to be built!🤣🤣(I went on a old airplane buying spree last year, have enough kits to keep me busy for a few years!🤣🤣🤣🤣🤣🤷🏻♂️ Can’t wait to see that thing fly, and always click on your videos as soon as I see them!🤘🏻🤘🏻👍🏻
Thank you for the new Video! Today i've reloaded the RUclips page again and again while hoping for some new stuff, and there it is... thanks again and keep goin...;)
Oh a small one, get the wing extensions! Until the Believer came along this was my fav airframe.
She is enormous! Looking forward to seeing what your nose job will look like. I always wanted to build this kit. I would mount the camera in a makeshift shelf in that bubble and open it with a drill wide enough to poke the lens out. But that's me, and I don't have your craftsmanship skills.
At this point I'm thinking to just make a copy of the mini-talon front platform, I like how easy it is to get at.
The only guy I know of that has a data flow chart for his planes and actually does the programming. Me thinks he may be intelligent life. :) Wonderful glide... The larger the plane the slower they look, yes. A 747 looks like they are in a hover coming in for a landing. As for tip stalls, how come builders don't build in wash out on the tips?
Depends what kind of plane you want. Washout kills lift and is only important at a rather small section of the overall envelope. But if the lack of washout could kill people then it becomes rather more important than on toy planes :)
I love my Big Talon, also highly modified... Very stable and long distance capable.. Lookin forward to see what you do with yours. Cheers..
Stable? I found it very hard to fly. It reacted dramatically to any control movement and had terrible tip stall. :(
You don't have to wait 10 minutes before pressing the the parts together for the uhu por to work. You can instead wait for only a minute or two, this way the glue won't instantly stick with a lot of force, allowing you to slide the parts in. The disadvantage of this method is you need to give the glue a long time to cure before it reaches full strength and maybe it never reaches full strength at all, I have never tested it to see if it does. That's not a problem for me though since uhu por is strong enough for my purposes regardless of the way I use it.
Also, hobbyking sells tubes of clear foam glue that is similar to uhu por, just thicker and cures quicker. It is quite a lot cheaper if I remember correctly so maybe take a look at it if it sounds interesting. It is generally not as good as uhu por but I sometimes find it more pleasant to work with when I'm glueing smaller surfaces
Iv been using super glue since day one...never had any problems. And day one was 4 years ago.
This airframe is a beast, have fun with her!
You don't have to wait before putting stuff together with POR it is just that then the solvent takes a much longer time to diffuse out so you have to wait something like 24H for the bond to reach close to max strength
Try and get hold of some of the wing extensions although having a look about they seem hard to get now. Brand: X-UAV
Item: Wing Extender Length: 15cm - I thought the camera dome was horrid.
Hard? They are impossible to get.
love the long ones Chris
"love the long ones". That's what she said.
Have you try the ExpressLRS? I'm sure you can contribute the project
You just need to add some image recognition AI for sheep & cows and you’ll be able to offer automated livestock counting services from the comfort of your arm chair!
Excellent. I liked it
With that gilde-slope you might catch some thermals on a nice sunny day... nice Review! :D
Nice to see one not crashing like mine did.
This plane is looking quite great.
Getting 5h flight time would be amazing and I'm looking forward to more videos about it.
Keep up the good work!
Unfortunately, with the Brexit the UK warehouse doesn't ship to germany.
That's really sad, since the chinese warehouse charges double the price, which is 248 EUR instead of 119. Thats btw 290 USD.
I noticed some beefy price differences at banggood lately, but 100% is just madness. Too bad, since several fpv platforms just aren't attractive anymore with those prices.
Yeah the price that I was referring to as "kinda high" was the $180 or so it was when BG sent it to me a few weeks ago. Looking at BG just now it's listed as $299! And then $85 shipping to New Zealand. And then add 15% for the NZ govt mafia GST... comes to about NZ$600 !
@@iforce2d jeeppers, that is horrendous. Lol my $300nz VQ Manaro made of balsa and ply, reasonably rebuildable, if it hits the earth harder than my ruff arse landings sounds pretty dame good to me, just starting too wish I went electric rather then using the 20 year old ASP91FS I had sitting o my shelf. And Hello from Palmy north man, keep up the great work and awesome videos. Will be very interested in your data board thingy if you bring to market
@@iforce2d Most popular planes and related RC parts jumped ~10-15% right at Chinese New Years. Not sure why the 50% jump with the Talon. 😱
The price of a STM32 chip on JLCPCB went up by 5 times since August last year, the only reason seems to be the Cooties-19 hype circus. Yesterday I paid $48 for an omnibus F4 that used to be $32. Look forward to more of this for a while it seems.
@@iforce2d On the chip side, there is a real shortage and demand issues due to the high volume of consumer electronics. Also some side-effect due to trade from USA-China politics (from policies over last couple years). Used chip making hardware has gone up 20% since beginning of the year. Global automotive manufacturing has idled a number of assembly lines due to chip supply limitations.
Not sure if there is a foam shortage.
34:37 that exactly the same condition when i made my talon crashed hit into the tree
i'm pretty sure you not expected that the talon turn too close to the tree isn't it :) big size make optical illusion which seems still close to us but actually it far away and we realise it when it hit the tree (which fortunately you get luck at that time) LOL
thats why i'm not trust my eyes anymore to fly LOS with my talon and always fly higher than some trees
Not luck, like you say just fly higher. As long as you can see some sky between the plane and the tree it doesn't matter how far away it is.
Just like compared comparison, loved it mate :D
Might be interesting to install some vortex generators to see if you can keep the wings flying near the stall and prevent the wing drop.
Great video! A few comments: I like to use an APC 12x10 thin electric prop for my Talon. Yes, big planes seem to move slowly, but in reality they don't. 60km/h is the sweet spot (range efficiency) for the Talon. And, finally, most planes tend to climb under power, and they should. Think of it from an energy point of view; What happens to the extra power you put into the system when you raise the throttle above what's required to overcome drag in level flight? Exchanged into potential energy (altitude) ofc ;) However, the Talon should be pretty pitch stable wrt throttle. At least mine is - but maybe it's less powerfull (3548mm 700KV SK3 w 12x10 on 3S LiPo) than yours
영상 잘 보고 갑니다,,,,
I had one. I painted it Grey to look like a military drone. Loved it but couldn't fly it. Crashed hard on the first flight and it was totally destroyed. It's very hard to fly. You need a lot of weight to balance it. The wings are very thick and heavy. When it goes down the body destroys itself. I was so sad and couldn't afford to replace it. It really suits a experienced pilot. Also needs 4s. I tried on 3s and it seemed to not have enough power to recover from a stall. Not sure what else is needed make it fly easier. Less movement?
Perhaps it was just a little tail heavy. In my experience this has been one of the easiest to handle planes I've had.
I originally thought the mini talon was butt ugly. Then I realised it was almost identical to the Desert Hawk military drone designed by Lockheed Martin. Then I just had to have one.
Ha! Me too!
Wonder if you could take that transparent dome thing and stick it underneath to protect a PTZ camera system.
Interesting video as allways
Thanks for sharing :-)
@0:50
Banggood name checks out :P
Was the unintentional easter egg the Glide Slope Calculation? What a treat to see the info screens on the footage btw!
I can't wait for the ArduPilot videos.
i have one of those i won from a fellow flyer, have to put gear in it, but it's one helluva big bugger
Quite angled sunlight for an object that's supposed to be hundreds of thousands of miles away 1:34
Well if you look at the sun directly the rays go out in all 360 degrees around it, so you can get literally whatever angle you want depending on how much of them you look at. That photo is just showing a small section of the total.
I don’t see a reason to expect that a foam aircraft of that configuration wouldn’t drop a wing at power-off full stall. Your exploration of the envelope there has told you not to do that, and how slow not to go in order to not do it. Try it with power on straight ahead, then straight ahead with abrupt full up elevator, then in tight banking turns. Offer all that data, plus everything you develop on glide slope, what cows to avoid, etc. to your autopilot.
A couple thin coats of red ink would look nice while adding minimal weight, just a thought.
I've had some that were flyable with the stick full back, eg. C1 Chaser and homeslice2. I guess that's not a full stall though... in any case I will probably be putting an airspeed sensor on this one, so hopefully that should avoid any stalls in auto modes at least. I tested a little with Ardupilot yesterday and was surprised to see this maintaining altitude at 70-75W power!
should make a nice platform for a light kamikazi drone
Hi, I've been fascinated with these sort of FPV flying wings for a while now, do you have any recommmendations for someone who wants to get into them? Thanks in advance.
Good model👍
Ooh! The Big one!
Bang-good? is that some kind of tinder knockoff ?
anyways, nice plane tho.
@@DawgPro I think you missed the pun...
Hi nice work.
May I know the flying time you got with 10 Ah battery?
about 100 minutes
ruclips.net/video/SS7DVXWBMpc/видео.html
I would have loved to see the power consumption. Can you tell us something about it?
I'll have to put a flight controller on to measure that next time. As a very rough estimate, around half of a 10Ah battery was used over 40 minutes, so average current 7.5 amps. Voltage under load would probably have gone from about 4.05 to 3.75V, so average around 3.9V, or 15.6V for the pack. So that would be around 120 watts.
These things were about $100-120, but after covid current prices are around 300. Then toss the $50 for shipping...
Covid has currently killed my hobby.
Would you mind sharing which program you were using for programming the controller? does it generate c++ code?

Where did you get the Uhu por from? Bunning's? I've been using the CRC Ados spray adhesive on foam and it seems to work well, plus you have about a 2 min position time.

18:14 duty cycle pwm output?
i thought servos run at 50Hz
Duty cycle PWM is not for servos.
en.wikipedia.org/wiki/Duty_cycle
en.wikipedia.org/wiki/Servo_control
@@iforce2d
first link: "Duty cycle is commonly expressed as a percentage or a ratio"
second link: "Servo control is achieved by sending a servo a PWM signal"
from the first paragraph of both
the progam wants you to set the duty cycle in Hz
servos are controlled with pwm
something is very mixed up here
Yeah... I think it's you. :p
Like I said "Duty cycle PWM" is not for servos. Servos use "Servo PWM" which is a different feature to what was visible in the video, and does not have any refresh rate setting. I actually spent some time trying to come up with more distinct naming for these to avoid confusion, but eventually decided that with some demos and decent documentation it would be ok. I might have to reconsider.

@@iforce2d i have programmed both myself
but i don't see the use for normal pwm on a flight controller thing
so there was the confusion
Was your glide slope calculation inverted?
Nice if them to include a muesli bowl
Great review and outcoming info! Like #303
Never played with the programming software before, but do you have the Invert Source & Color Green values both set at 10?
No, I reversed the parameters for the glide slope calculation.
How much downthrust was called for in the instructions.? Usual source of pitching up under power.i.e. not enough downthrust
No mention of anything in the instructions. All the molded parts fit like a glove to each other and the plywood. I would expect the motor should be just mounted flat to the motor plate, which was angled slightly.
@@iforce2d well some down thrust should fix it's pitching up under power then. May only require a couple of small flat washers under the top mountings.
Are you able to use your SBUS mixer for a pitch/throttle mix?
Yes, but I think it would be very hard to balance effectively. Better to have a gyro/accel for closed-loop feedback.
is that a v3 kit?
It did not come with the little side-wheels for the wings, if that's what you mean. I don't think there's any other difference between the new and old kits.
Do you think vortex generators might help with the tip stalling?
Possibly, but it's not really an issue I think for a long distance cruiser. The stall speed at this weight was around 30km/h which is pretty decent and makes for easy landing. As the weight goes up, I think flaps might be a more useful mod.
@@iforce2d That makes sense, thanks!
which controller use that visual interface to programming?¿ and what camera u use to film in flight
I'm making the controller system, it's not ready yet. Camera is Runcam2
@@iforce2d I mean whats the name of that software, thanks!
I'm still making it..... it has no name.
What cam are you using on the plane?
Runcam2
@@iforce2d thanks
Yeah, the big Talon was never very popular...Im sure it will fly okay, its just not as convenient as the Mini I guess...🙂
Yeah it's a bit harder to just throw it in the car, and the mini-talon can still carry a decent amount of cameras etc. The dome is also kinda inconvenient unless you have a good runway and you know it will stay clean and safe.
@@iforce2d Yes, shame really, even with just one ten amp Lipo it flies really good IMO
I think that dome put a lot off, the sun flares off it as I recall..Wish you did long range flights, that landscape is really weird...lol.🤔😳😀🇬🇧
would it run on 3s?
Yes, I flew it on a 3S 15Ah li-ion pack, no problem
@@iforce2d on what size prop Did you run it On with that pack?
Same prop, 10 or 11 inch.
@@iforce2d I struggled with 3s. Crashed and destroyed itself
I wouldn't. It needs power to recover from its scary stall habit

$563 banggood No way..lol so over priced, you can get it cheaper than what they sell it for, and there shipping is very expensive too ,at least to Australia it is....
Why flysky??
Why not?
Of course!!.....but do you really like them or they are sponsored?(sorry!!)
As my experience, flysky is a very good balance between cost and benefit. Just out of the box I managed to make 3.8 km away flight with an Fs-i6 and fs-ia6b, then you can add advantages like firmware mods with a lot of channels.
So, why not ?
I think, it just works..!
