Please Help - Elevon Mixing Issues - Discussions

Hello,
I have an APM 2.5 installed in a flying wing airframe. I previously had this APM in a multicopter and had it working well. I installed the ArduPlane V2.72 on the APM, and downloaded and installed the Skywalker Parameters, and calibrated my radio.

However, while this may be a noob like question, I for the life of me cannot get the elevon mixing to work right. It seems no matter what combination of reverse channel selections I make (APM & Radio), how I hook up the servos, it's either wrong in stabilize or manual mode.

Is there a setup guide around for this? I saw https://code.google.com/p/ardupilot-mega/wiki/APM2RC but I am not certain which is correct for the wing - the # selections and color coding is opposite. I guess I should start off with knowing for a fact which wing servo gets hooked to what input

Also, do you guys typically need to reserve any channels on the radio itself? Also, does the mixing need to happen on the radio or APM? Or both?

Thanks!

I just checked my wings., all have output 2 from APM to the starboard / right wing. All fly ok. The picture is correct, the text is wrong .

Connect as per the wiki and mixing needs to be set on the APM and the rc

You need to do this in the correct order. Calibrate the radio, then in stab adjust the direction of the servo until the surfaces response correctly when you pitch or roll the aircraft, then select manual and adjust the radio to get the correct directions as you move the sticks

P.S. I am using a HobbyKing Phantom flying wing. The servos are on the bottom of the wing, with the control side facing outward
