In Loiter mode, after arming operation from RC, the RPM of the motor started to increase even though no throttle rise operation was performed.
Normally, after arming, the motor should rotate at the pwm set in MOT_SPIN_IDLE, and the motor RPM should not increase until takeoff operation is performed.
Can you please help me find out why this event occurred?
