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..

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.

That only works in manual mode..  In anything else it's using full throws.. :(

Send me a PM and I'll hook you up with the script..  I use a modified radio though, I removed a trim pot and installed a 3 position switch for camera control..  and use Canon S100's so your's may or may not work..

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.
I sent you a friend request which is required before we can PM. You can also just email my hotmail accound using iskess@.

I'm using the SX260 so not sure if it will work, but it will teach me how to script. I have the Taranis radio which has all 3 way switches except the throttle kill and trainer.
