Have a skid steer rover with 2 brushed motors with relay (relay sets direction, pwm sets speed).
Due to mounting I have to reverse the direction of one of the motors.
However if I reverse the servo the trim is set to maximum on reboot and the motor spins full speed (even in Failsafe!).
If I start without reverse and change it to reverse during operation it works as expected (because trim is still minimum until next reboot)
How do I reverse only the direction relay?
