I have a problem with the tilt-rotor servos. When I connect the FC the servos tremble a lot in Q modes. But if I change to plane mode they stop shaking.
If I have Q_ARAT_YAW_P = 0.018 (default value) they tremble little, if I raise the value of this parameter to 0.5 the vibration increases.
I have the Pixhawk 2.1 Cube on silentblocks; I tried to leave it rigid in case the cause was too much antivibration but it remains the same.
I have also removed the Dragonlink Rx antenna by placing it in the middle of the wing but it remains the same.
At the beginning if I change to plane mode and stay in a few seconds when I returned to Q mode then the servos stopped shaking. But now this does not happen anymore.
