I can’t get QGC(4.0.8) to calibrate my radio (Frsky X9D+). Each time I do radio calibration QGC sees my stick input until the last stick input (pitch stick down). I’ve even tried holding the elevator stick down with a rubber band, but no matter how long the stick is down I get no response. Out of desperation I move the stick around pitch and roll. This causes QGC to accept the pitch input and combine it with roll.
While calibrating, the channel monitor monitor shows all the channels operating as expected.
What do I need to do to get radio calibration to function properly?
