While not familiar with that particular plane, most will have a simple Y-Harness that connects the 2 servos into one channel. Both servos will move the same movement when connected to the receiver. Connect the ailerons so that the pushrods are on opposite sides of the servos. This way when one aileron moves down the other one will move up, and vice versa. This is the easiest and simpliest way to connect your ailerons.
