ESC connected to channels 2,3 (Function Motor 1, Motor 2)
The issue is that ESC not beeping and doesn’t react on the throttle when armed.
Lots of docs about changing mot_pwm_type, which is missing in my config list, I am using Arduplane 4.3.1.
MOT_PWM_TYPE isn’t present on plane. On fixed-wing it will use PWM by default on the “throttle”, “throttle left”, and “throttle right” outputs. The “motor” outputs only come into play for quadplane VTOL aircraft.
SERVO_BLH_OTYPE sets the protocol for the output channels given by SERVO_BLH_MASK, as you have done.
