Simple except for me at the moment. I have a foam wing, 9CAP TX with Elevons activated. Left Elevon in Ch.1, Right Elevon in Ch.2, and ESC in Ch. 3. When I turn the sticks right or left, no problem (i.e. elevons respond appropriately). But when I pull back on the stick, the elevons both turn downward (when they should both be turning upwards). It is not a servo reverse problem, but I can't remeber how to remedy this with the 9CAP. Thanks!
