Bill,

On page 3 of your instruction manual (if you don't have it you can download it from the Tower website) it says you'll have to buy "two 6" servo extensions for the aileron servos". You will also need a "Y" connector to tie them together unless you plan on running each aileron from a separate radio channel (computer radio only). Go with the recommended length. Loose wires have a tendency to want to get caught on servo arms inside the fuselage. Keep it neat and you won't have any problems.
