I’ve previously done an manual ESC calibration and i’ve found, when calibration done and arming the system, the Channel 4 don’t start the motor with the same throttle value than the 3 others motors.
to test this i’ve do manual calibration on the same channel (2), and when i replug the esc on the correct chanel, there’s the same pb on the chanel 4… Strange…
To try i’ve done an automatic calibration. Once done, when i arm the system all motors spin same time, but even when throttle 0%, and into Mission Planner the parameter “do not spin motors” after rearm is set !!!
