I just tested r220 and all worked perfectly. I tested the signalling, headfree, RTH and missions (waypoints & orbit).
After looking at the logs I realized that one motor had no throttle in the mixer so that the mot_yaw was on +150 all the time XD
But it flew pretty well / stable and had only minor problems achieving the correct heading. I guess the throttle got lost in the transmission of the mixer data with QGC B3

Thank you guys

Greatings,
