Help! Y3 VTOL Plane pitch oscillation

[mathirj]

Thank you for getting back! What do you mean by sharing the same ground pin? I am using pixhawk 2.4.8 powered by the power module and using a 5v bec for powering the servo rail.

Are you using separate 3 pin connecter for the servo?

Btw I managed to fix the servo jittering issue, had to decrease the yaw P and increase D in small amounts as guided by a user in other form.
This is what the first test flight looked like. Still oscillates slightly. My guess is to correct it by lower P of roll.

One question. Is it better to extend motor to esc wires or esc to battery/pdb wires?

Very happy to hear that. That oscillations will be gone once you fine tune your PID.
Good luck with your next test flight!

It is better to extend the ESC to battery wires than the motor to ESC wires.
