Radio calibration failed

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 different 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?
    Thanks for helping,
    Itzik

@ITZIK RONEN,
What Ground Control Station are you using to calibrate your R/C transmitter?

Hi
I’m using the latest version of the old APMPlanner (Obrian…) (:
The APMPlanner2 didn’t work for me. I couldn’t save parameters etc’…
