Yes, a 6 channel receiver is plenty for what you want to do. You will/can run the aileron servos from one channel in the receiver, plug a Y-harness into the aileron channel on the receiver and then both of the aileron servos will plug into each end of the Y-harness. With this setup you only need 4 channels of the receiver. Even if you use a seperate channel for each aileron (by using a computer radio) you will still have enough channels on the receiver because you only need 5 channels for the servos.

Hope this helps
