I've been watching a few of your videos, the builds you do seem quite interesting. Subscribed!
Got a Pixhawk Cube build starting soon :)
Congratulations! Nice build and flight. I've been thinking about building a camera platform with a Pixhawk or a F3/F4 with iNav. So, it was cool to see a new build on the Pixhawk. Thanks for posting.
An F3/F4 board with iNav is certainly an inviting prospect for keeping cost down, but the more I researched Pixhawk it really did seem to be the 'de facto industry standard' for so many UAV endeavors - whether in the air or on the ground or on the water. So one of the reasons I decided to go the Pixhawk route was so I could get to grips with a platform that I may encounter again & again in the future, both in my work & my recreational endeavors!
Thanks. Good to know. I will likely try the Pixhawk for a build.
Comprei 1 desse... só que 1 motor está meio raspando... teria alguma dica de manutenção antes de eu botar a funcionar?
Great feeling not to crash on your first flight. I've done that several times :-) I also built the 650. I use multi star 4114 Motors, 17 inch props, and a 6S battery. I think they only recommend 15 inch props but mine fit fine and the 650 is built well enough to handle it. I got 22 + minutes of conservative flight time. I did not push it at all. The only reason I brought her down was because I thought my voltmeter was failing. Probably could have gone another five minutes. I've built several Tarots, the 810, 960, and the latest being the same as yours, the 650. I have to say the company does a very good job putting them together. All the pieces fit perfectly into place. I only complaint would be, the 650s landing gear felt kind of flimsy, and a couple of carbon fiber splinters which really suck. Anyway, congratulations on your successful Maiden flight.
Interesting you should comment now, as I'm actually about to embark on a rebuild of this quad onto the Daya H4 680 frame. The Tarot certainly feels sturdy (except for the aforementioned landing gear), however I'm not a fan of how it folds - the amount of force that you have to put on the clips to open/close the arms (& the amount the top/bottom plates flex in doing so!) makes the process inconvenient & I'm constantly worried about damaging something when closing the arms by jerking too hard when they finally leave the clips. Plus the folded form being so long is inconvenient for me for transport compared to something that folds into a shorter, squatter shape. I'm actually selling the giant Peli iM3220 case I bought for the Tarot & using the proceeds to pay for the Daya frame, which should fit into one of my much smaller wheeled Peli cases.
That's true, I never unfold mine. It is so hard to do it is as if it is not meant to be unfolded. I like the design of the 960 and 8:10 with the wing nut clamps. That 650 should have done something like that. I rarely unfold any of them because when I fly I simply put them in the back of my pickup truck. Storing them, I place them in Rafters on the ceiling I built so space is not too much of an issue.
Mine went with me all around Pakistan & Iceland, so folding & a hard case were required!
How much load capacity
What voltage that you set for the low voltage alarm?
btw, you have the exactly same thinking when i first flying the 650 . "will it fly?", "what happened when i switch flight mode", "will it fly away and crashed horribly" 😂
I think the critical alarm in Arducopter is at 21.4V (3.56V per cell) but I generally watch the voltage on the Taranis or laptop/smartphone & judge it myself.
I was even more worried when I tested failsafe, intentionally switching the Taranis off with the thing in the air was terrifying!
great build, doing that as I watch your video gartt ML 4108 500KV, you did not use the PDB that came with the Pixhawk 4?
I didn't buy the pixhawk with a PDB. That Tarot frame was a huge pain when it came to power actually, one of the first things I changed when I moved to the Daya H4 680 was to drill mounting holes for a regular 6S capable 30.5x30.5 PDB from Matek.
@@CJDavies I had the same issues, found the original PDB from holybro, it made it easy, had to drill my own mounts for the board, created a third platform, used a 3D printed cap that allowed the wires from the motors( Gartt ML 4108 500KV) to be routed through the frame, the The only thing I regret is not having telemetry as with my other Quad builds. Using the Inav system, I had everything on one screen, here, its a mess, but in for a penny, so we continue
Which is better in between 3 hole and 1 hole propeller?
Neither is necessarily 'better'. The 3 hole T-style means you'll never have prop slip, but it's also not as suitable for repeated removal of the props (for travel) which makes quick release adapters (which are almost universally a pain) kinda necessary. With 1 hole props you can more easily remove them but you have to be more careful when tightening to make sure they don't slip against the motors.
This is awesome man! Do you know what the ballpark mac takeoff weight would be with this batt/motor/prop combo? Also what was your flight time like with the 8000mah 6s you were using?
Max takeoff weight would be somewhere around 6kg, but I wouldn't want to above 4kg or so (which means a ~2kg payload once you've taken the weight of the quad + batteries out). Hover time on an 8000mAh 6S with no additional payload would be pushing 25 minutes. The figures that eCalc spat out were pretty accurate from my experience, it's well worth the paltry license fee if you're thinking about playing with bigger setups like this.
@@CJDavies Do you mean the license fee for eCalc full feature set?
@@flighttherapybullisticfpv133 I mean the $8 annual fee for xcopterCalc, if you don't pay you can only access a very small number of motors/batteries/etc.
Hello bro! Good video!
I am building my drone with this config:
Tarot 650
Pixhawk 4 + GPS
Tarot 4006 620kv / 13x5.5 prop
ESC 30A SimonK
Battery 4s 14.8v 5200mah
Taranis RC + FrSky X8R
Total weight is 2kg
The problem is that the ESC and the tarot 4006 burn many times and I have to buy all the time. I do not know why ...
Calibration of the ESC is done by Qgroundcontrol, including the PX4.
Not much information about the Tarot 4006 620kv...
Do you have any suggestions?
Your setup looks fine in eCalc (i.gyazo.com/36ee4a532dffe7c61a40e38fddcc7b9c.png). What conditions are you burning motors/ESCs? In the middle of flight? After a crash? Have you managed to complete an auto-tune yet?
could this motor work with 4s lipo
No, kv is too low for 4S.
Would you say those motors would be great for hex?
They're cheap, but not particularly smooth or well balanced.
Hey i was wondering do you build any drones for purchase??
No, there simply isn't a market for it here.
Can you suggest the total thrust delivered by this quadcopter. or maximum payload that it can carry.
Total thrust of the setup in this video is just over 7kg & the weight with a 8000mAh 6S is a bit under 2.5kg. An additional payload of 2.5-3kg should be possible in gentle wind.
I am asking this because we are going to have a competition in university level. there we have to carry a payload of 2.5kg. will you suggest this setup for the competition?
Generally it is a good rule of thumb to aim for a 2:1 thrust to weight ratio. If you put a 2.5kg payload on a setup like this, you would have a thrust to weight ratio around 1.4:1 which would fly fine but wouldn't have as much performance or as much ability to withstand higher wind as a 2:1 ratio. Take a look at www.ecalc.ch/xcoptercalc.php which lets you calculate thrust, power consumption, flight time, whether you're overloading your motors, etc. with a whole range of different motors/ESCs. It's a very useful tool when building larger copters & well worth the small subscription price!
Thanks for support CJ Davies
Whats the flight time you're getting CJ?
I haven't finished configuring/testing the voltage warnings/current sensor yet, so I've been being quite careful - I was getting ~8 minutes of fairly hard flying the other day on 4000mAh 6S packs which recovered to 3.85V per cell, so I'm hoping for maybe 12 minutes slow flying on those 4000mAh packs when discharged to maybe 3.6V & maybe 20 minutes on the one 8000mAh pack I have & when using two of the 4000mAh in parallel.
CJ Davies Go 10000 mAh. I've seen people flying 50+ mins with that battery 😂
IM THINKING OF BUILDING SOMETHING LIKE THIS .NICE JOB HOW MUCH ROUGHLY FOR THE SOME OF THE PARTS ...
Tarot 4108 380kv Motors work only with 6S battery?
I've only seen people running them on 6S & there aren't any current/thrust tables for anything other than 6S. I think 380kv would be too low to get good performance with less than 6S. If you're looking for something similar price/quality for a 4S build, there are options like the Tarot 4006 620kv which are designed for 4S.
Thank you i'll check them out.
Well, my only concern is that i already have (2x) 3S 3000mAh 20c batterys and (1x) 4S 5000mAh 30C from my previous build.
and i'm trying to find something to work with both on my new 650sport. Maybe ill go for SunnySky X4108S 380KV.
Dimitris Geroulakos The Tarot 4S 4006 is one though motor to be said, although quality isn't number one :)
In this configuration, it is much better to use Gart ML5008 for 400KV, the efficiency of such an engine is 5% better both in power and speed.
I would think 5008 400kv is better suited to larger props than this frame can fit? Maybe 16-17"?
Whtas flight time please?
Roughly 15 minutes on 4000mAh 6S & 25 minutes on 8000mAh 6S without discharging too low.
hi;
can you share your PID config
Sorry, I no longer have this copter. My PIDs were just from AutoTune.
If you had problems building it, perhaps your approach was incorrect. I have watched many videos about this craft and the build looks straight forward enough.
Take a look here... ruclips.net/video/4H4Mjw7wpys/видео.html
Also, if you take a look at Peter King's channel you can get lots of information about setting it up.
