I am confused about how to set up the radio for dual aileron servos. I want to be able to utilize my ailerons for flaperons. I am using JR equipment. I have a X-378 7-channel TX and a 6 channel reciever. Should I plug the left aileron in channel 2 and the right aileron in channel 5 (aux)? How do I program the TX?

Thanks in advance for any help.
