So last fall I posted about my P1 crash when the motors simply stopped when it was at a hover about 40-50' above the ground. Never figured out why that happened.
But I've recently had time to try and get the P1 flying again and it's very squirrely with any inputs and will not hold position in GPS mode when I let go the sticks. When in GPS mode instead of hovering it 'slides' off to the side and loses altitude.
I've calibrated the TX, the compass, updated the software and did an advanced IMU calibration. Props are balanced. I also pulled the lid to check for any loose connections and found nothing.
So what I am wondering is could the compass be physically damaged (shows no external signs)? Could the IMU be damaged (no physical signs)? The crash was in tall thick grass, but it fell hard enough to bend the gimbal because the gimbal hit a hard lump of grass that the landing gear straddled. No other physical damage than the bent gimbal and broken 2 prop guards.
Any thoughts or suggestions are much appreciated!
