Hello guys! Before you post classic “board orientation, prop config, motor direction…” I have checked everything, no, I mean I actually checked everything 50 times. Few things to clarify:
it’s a ducted 3.5"
it runs ardupilot and yes, I do need it.
if I flash bf on it then it works totally fine.
It managed to liftoff once without a problem, however without changing any settings I’m no longer capable of doing so
it does a front flip every time like front motors direction is reversed, however I’m totally sure that it isn’t.
I run props in, X frame, pusher config
FC is mounted in 315 yaw config
The only idea I might have is that it has bad gyro filter those resulting PID loop freaking out
As @amilcarlucas eluded to, Betaflight and Ardupilot have different motor numbering and order. If you didn’t set the frame to Betaflight X, or manually re-order the motors then they won’t work right. Have you used the motor test in Mission Planner? Front right is first, then it goes around clockwise.
I don’t think it matters if it is X or Beta-X if the motor order and direction test is right in mission planner, because it uses A B C D and not 1 2 3 4. And I think we all have seen the video and that it is correct.
Yea, you can make a random choice in Frame type and re-factor it after running Motor Test. Used to do it routinely with 4in-1’s before all the additional frame types were added.
Add this to the Speedybee list of problem forum posts. They sure suck up the oxygen.
Okey guys I’m back and here is what I’ve found: if I start from a slope it actually flips the other way, so now I’m suspicious that PID controller is just disabled or smth. Could it be the case? Thanks for help anyway
