After the "radio calibration" procedure is done I'm getting the message that channel 2,4,5 or 1.6.7…. "Failed to set channel x". Every calibration the error is in deferent channels. Only one time I didn’t get any error.

However, the channel PWM summary looks OK and all channels are working:

  1. What is the problem?
  2. Is it safe to fly after getting this message?

The setup:

Mission Planner 10

Pixhawk with last Arduplane firmware

Thanks for helping,
