Usually, you would use a Y harness to connect the leads of two aileron servos together to plug into channel 1. For the aileron and rudder, two differnt servos on a normal plane. These go into two differnt ports on the receiver. Rudder work in the air is important, but basic turns on a trainer can be accomplished by just using the ailerons. You also need to learn to use the elevator to make level turns without loss of altitude. If you are still in the beginning training mode, I do not suggest the mixing of rudder and aileron. Learn how to fly the four basic controls (aileron, rudder, elevator, and throttle) using the sticks under youtr thumbs. You need to learn how to mix them manually before using the computer radio to assist.
