On the other JR's you don't use the Y you turn on the flapperons and plug one aileron servo into the aileron and one into the aux port of the receiver. The throw on the flaps might need to be changed to a - value instead of a + to get them moving in the right direction. I have not had to mess with my set-up for a long time so I hope my memory is working . he he The info in the manual under flapperons should help explain it and show a diagram to help. Hope this helps I am at work or I would get a manual and try and help more.
