Setting up a new plane, I am installing the Ailerons. On the 9c, I want to use Channel one for Right Aileron and Ch. 5 for Left. So I pluf the left Aileron into channel 5 and get nothing. Move the stick, nothing. Check the battery, fine. Put the left aileron in channel one to verify the servo works, and it works fine. I cannot get channel 5 to be left aileron, am I missing a setting? This is a brand new plane in the 9C, so everything is stock right now..
