Bane of G10
I've had this issue for a while and I'm getting nowhere fast.
We ordered this rig from Intelligent UAS (first mistake... don't ask) last year and finally got it. Unfortunately, it has an odd tendency to wobble very time I return pitch/roll back to center.
The controller is an A2. Motors are KDE 5215XF 435KV 22P, ESCs are KDE 75A HV. Props are APC 16X5.5MR (switching to new 18X5.5MR once it's sorted). Batteries are Tattu 6S 16,000mah (2X).
Here's some video. I had a friend take it today and didn't realize I had it on low quality settings, but you can still see the wobble.
So I first noticed this on the early test flights. Having the MoVi gimbal installed didn't make much difference, just dampened it slightly (at about 9lbs AUW).
I tried a multitude of gains ranging from scary low to scary high with no effect except for speeding up or slowing down the wobble. Firmware was fine. All the setup was fine.
I finally sent the controller back to DJI, and they sent it back with a new IMU, saying the old one was bad. Great, I reinstalled it, updated everything, set it all up again.
Test flew it.... same problem, no changes whatsoever. Went through the gains process again with no improvement.
Emailed DJI, they told me to send it back again, so I did... they sent it back, saying that the problem was a firmware mismatch (even though that's the first thing I checked when I received it previously). Great, whatever, tested again today... same problem.
Now, I'm starting to think that the issue might actually be with the combination of airframe, motors, ESCs and props that I'm working with. Our Cinestar X8 with U7s and T-motor ESCs is absolutely LOCKED IN with a WKM, no issues like this.. once I got the gains where I wanted them it flies like it's on rails, gimbal or not.
Nothing seems to be working with this though.
What's really frustrating is that we were originally supposed to get a Wookong on this bird, along with U7s and T-Motor ESCs, but Intelligent UAS decided to "help out" by upgrading to these motors and ESCs and the A2 without asking (I mean, good on them for trying to help, but... crap).
My next step of testing is partially completed. I have the A2 installed on a DJI F450 and have already flown a short test hop in the kitchen. I'll fly it outdoors tomorrow and see if the problem is still there.
Any suggestions?
