Channel 8 PWM

I have followed the instructions for channel 8 and got it to kind of work.

The channel 8 pwm values only vary from 992-1645 in the radio calibration page of mission planner.

As far as I can tell this value needs to hit at least 1800 for the function to trigger.

I have done the radio calibration and those are the values that I get.

Any thoughts?

  • I am in the same situation.  I have channel 8 set to 12 which is return to armed yaw and tested it yesterday with no results.

    I don't recall my exact pwm values but seem similar to yours .  I was going to try radio calibration again.

    I'm not sure what to do if the value isn't high enough to trigger a reaction.

    • I was wrong about my numbers.  Ch 8 goes from 992 to 2016.  Sorry, I don't know how to correct your problem.

      I still can't get this to work though.
