I have been working on a Tricopter VTOL for the AR Wing Pro.
Managed to get all the required hardware (i think) on board and within maximum takeoff weight.
Running a Matek H743 Wing FC and a Rpi zero with UavMatrix as a companion computer to provide telemetry/video back to mission planner over 4g.
Mostly just been performing hover tests over the last few weeks, and I have even flown it in FBWA mode once but the instability is making me very nervous.
Can someone help me understand if this is a mechanical design issue or tuning?
You will notice in the below video that the yaw axis oscillates noticeably, It also has a tendency to lose altitude when flying forward in Q_HOVER. The main concern is that it does not seem to be able to maintain control of its position if switched to Q_LOITER and will overshoot to the point I must regain control to avoid a crash.
The below video is in Q_HOVER mode. Almost no wind.
