I have an edge 540 (The Judge) from hobbylobby.com. This plane uses one servo each for the ailerons. The radio system is the Hitec Flash 5 with Hitec micro servos H55. Do I need to use a Y connector hooking right aileron servo to left aileron servo and plug Y into the aileron channel? OR, Hook one servo to channel 1 (being aileron) and hook the other aileron servo to channel 5 ( being gear or aileron/elevon or flap/flaperon ) omitting the Y connector? I am new to all this and never had a 5 channel radio or a plane with two aileron servos. To add more confusion for me, this radio is programmable so not sure how to hook up my ailerons the correct way.
Please help.

Here is the channel assignment:
Channel 1 - Aileron
Channel 2 - Elevator
Channel 3 - Throttle or Flap
Channel 4 - Rudder
Channel 5 - Gear or Aileron/Elevon or Flap/Flaperon Function
If going this route what channel to right and left aileron servos?
Thanks!
Rich
