Does anyone know any way of mapping the servo mid and end points that APM uses?
I have modified elevons on my Skyfun which, unfortunately, have a limited down travel. If the elevon servo forces it beyond the limit there is a risk of bending the pushrod or breaking the clevis.
What I currently have done is adjust the pushrod lengths so that at max stick and max trim (or min and min) the servo doesn't force the elevon against the stop. This is 965us and 2069us for each side respectively, however this solution puts the elevon neutral position way too high (pitched up) for anything near level flight
What I would like to do is map the servo outputs in two linear segments from min/down to neutral and from neutral to max/up. I can't see anywhere this is possible in APM at the moment, but it would be a nice feature
A quick fix would be just to add a neutral trim offset. Again, I haven't yet figured out how this can be done in APM, Anyone with any clues...?

Hi,
What do you mean with mapping? Usually mapping means associating each of the elements in one set with one in another..
You can see the min. and max. limits of each RC channel in the "full parameter list" in MP.
Be aware that if you use old style elevons in AP (where you have your transmitter set up for elevons too) you have to minimize and maximize the channels in RC calibration by moving the sticks to the corners that give you the min and max pitch and roll channel values. Just moving the sticks left right up down is not enough.
Elevons are not the most elegantly implemented feature in APM.

What is the way to do it in the new setup?
