strange YAW behavior

Hello there ! need you help :-)

got 2.2b4 Version on my Quad.

All fine : take off - stable

fly a bit - and suddenly when i want to change direction :

- yaw stick movement leads to oposite reaction....

Once the quad also started turning around 120 deg.

verry strange i know :-)

- Hardware is correctly set up and i can't find any reason for this strange behavior.

Any help is appreciated !

  • I have a similar problem with a helicopter.  It seems to only do it when I command right yaw.  First it jumps a bit to the left, then it starts moving right.  Yawing left works fine, however.

  • I also saw this, with 2.1 and now with 2.2, but I think it's because the magnetometer offsets have been reset during upgrade and it needs more time to settle. Does it get better if you try flying longer? (And I think magnetometer offsets are only saved during disarm but not sure about that).

    I also saw this when Yaw P (Stab yaw P) was not high enough to rotate, it moved a little in the right direction, then compensated stronger in the other - probably overcompensated by Rate Yaw P.
