See post 37 for my location recommendation. Near mid-aileron is nice but usually not done to keep wiring shorter. If the wings are apart, it will be easier NOW to install some form of wire guide tubes or at least cut a path. You may have to drill/cut a hole thru the ribs for them. take a look at your options, also described in previous posts, and select one. You have to be able to get the wiring from the servos to the Rec. Try to decide what length extensions you need to buy, they could even be installed permanently before covering if you feel the need(probably not on THIS plane)
