HELP ME PLZ 
this is radio calibration , and throttle is ok
but in servo output it is not working & locked on 1100
Unless you’ve disabled the safety switch none of the servos will move. I will usually configure this with BRD_SAFETY_MASK.
Throttle output will not move until the drone is armed.
The ESC Calibration you’re looking at is for AC, ArduCopter, not plane. Here’s the wiki: https://ardupilot.org/plane/docs/guide-esc-calibration.html

Are you supplying power to the servo bus?
How are you powering the FC? Are you using a battery or just USB?

Sorry to hear that. I guess you’ll be paying more attention to the fail-safe and RTL settings next time?
