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!

Try interchanging the plugs at the receiver and then reversing both channels.

Rodney, that made things worse: elevons went wrong direction when turning sticks left, right, and up/down (as opposed to just being wrong direction for up/down). I'm pretty sure I have to make something "-100%" that is "+100%", but I can't remeber where.

I thought you could just go in to the REverse menu and reverse the elevator

Alright, I haven't had to do any of this in a while, so forgive me if I'm being silly: I've got the right elevon servo in channel one, and the left elevon servo in channel 2 (which is the "elevator" channel in the reverse parameters). ESC goes into ch.3 (throttle on the reverse parameters). If I reverse the "elevator," which is channel 2, I've just reversed my left elevon. I'm missing something simple here.

I too have trouble setting this up right, I just experiment until it works properly. makes a difference on which way the control horns are in the elevons. On my flying disk (Round2it) I have the horns on top of the elevons and have the left elevon pluged into channel 1 and the right elevon plugged into channel 2 and all works well using a Hitec Prism transmitter. I don't recall how the reversing switches are set. However, there will be a combination that works for you, just be persistant and try one change at a time.

Ok, set it back up where your ailerons were right and your elevator was backwards. Hit the mode button twice and go into the elevon mixing menu. At the bottom it says ELE2 -100% ELE1 +100%. Reverse this so it says ELE2 +100% ELE1 -100%. You can also reverse the AIL numbers to change ail direction.

Rodney and Knighthawk, you guys are both right. I had to experiment with every conceivable pattern until the control surfaces were going the way that I wanted them to. The key was going back and forth between Elevon Setup and Reverse menus. Thanks guys, that was confusing!

I recommend not using any reverse try to use one menu or the other. I had some problems with my ultra stick when I started Rev. stuff in one menu and then un-rev it in the next menu. It gets very confusing.
