Hi Strongbad71, same problem with 1.8.0. Following your suggestion I uploaded the 1.6.5 version but issue still present. What type of airframe did you select? I tried with Generic Rover and Traxxas but the behavior is the same, no PWM output.
Some additional notes:
- I'm using a companion computer in offboard mode, no radio connected
- I've disabled several CBRK_xxx params to disable checks (RC, IO_SAFETY, SUPPLY)
EDIT: using Mavlink Console and passing the command "pwm test -c 2 -p 1200" steering works, same with "pwm test -c 4 -p 1800" throttle works fine.
