Setting throw limited on Elevons

Trying to figure out how to setup the elevon limits..  I'm using APM 2.5 with MP 1.2.78

What I'm trying to set up is:

Ailerons:  +1"  -1/2"

Elevator:  +3/4" -3/8"

I can get this setup fine in my radio the APM is using max throws..  Been trying to research this but coming up with nothing..

  • I guess I never had that issue because I always set my control throw limits mechanically.
    In Auto the APM shouldn't use more than it needs if tuned right. How is it flying?
    You could try setting the RC_Min and Max parameters directly, but MP is doing that for you when you do the calibration.
    Sorry I can't be of more help.
  • Hello Dennis,
    Once you limit the throws utilizing your radio, then you re-calibrate the controls through MP. That process teaches the APM the limits of the PWM signal associated with full stick input. I hope that helps.

    PS. Still wishing you could post your CHDK script utilizing shut_down.
