the value '1000' is not really magic, and it was resulting in sending a single 1ms pulse on all IO channels for a brief instant on startup. With some servos this led to the control surfaces being at extremes (and straining) on startup. It may also contribute to making ESC calibration harder on multi-rotors In the worst case it could cause a IC motor with reverse throttle to go full throttle on startup A logic analyser shows the problem very clearly. Changing the default_value fields to 0 from 1000 fixes the issue and no pulses are generated until an explicit value suitable for the airframe is provided via one of the many methods PWM output values can be generated Conflicts: src/drivers/boards/px4fmu-v4/px4fmu_pwm_servo.c src/lib/ecl
