This is really confusion; I have a Flex Innovations Super PNP Series Plane. I have the NX10 Transmitter. When setting it up I pick the Aircraft I select Model Type, Aircraft Type and select Dual Ailerons because I have 2 separate channels. I am binding it to the AR631 Receiver. One ailerons is on 2 and the other channel 6. After binding the receiver channel 6 aileron does not work. If I used another servo in that same channels (6) it works or if I use a y -harness it works. Question: Why the servo in the plane does not work after it is bind?

look at your channel assign menu and make sure it shows channel 6 for the 2nd aileron.....sometimes the RX assigns its own channel for the other surface............

Or just the servo monitor and see what's moving when you move the stick

Yep......that works too........if all is right....BAD SERVO??????
