Hello,
It could be a bug with Oneshot125 activation.
https://discuss.ardupilot.org/t/copter-3-6-4-oneshot125-not-enabled/37067
With Arducopter 3.5.7, when MOT_PWM_TYPE is set to 2, RCout status display a value between 125 and 250, same result when looking RCOU in log.
With Arducopter 3.6.2, 3.6.4 or 3.7.0dev, RCout is in the range 1000-2000
My card is a Navio2,
Thanks,
Marc
