Thanks to all you guys who have chimed in here. I will now muddy the waters even more. I was fooling with the transmitter trying to link ailerons (which were not working) with rudder so that just a simple ailerons stick move would give some rudder. Something I did made the ailerons work, but only with flaperons enabled. I have no idea what I did, but they now work if flaperons are on. I still have not figured out how to slave one channel to another. I want to slave channel 6 to channel 1 so that I don't need flaperons. And I want to slave channel 5 to channel 2 to operate the two elevator servos. By the way, I am using a seven channel FrSky receiver, that I took out of another plane and I know is good and all new servos except for the two servos in the wing. I do understand that those servos are old and probably need to be replaced. Even if they were new, they are a bit anemic for this size plane. But more than than, I want to figure out how to operate the more complex features of this radio. So far I have not been able to slave one channel to another and achieve the desired results. And I don't know why the ailerons did not originally work and now they do.
