I am building an Ultimate 40 ARF from Nitroplanes...as some of you already know

. I installed my Spektrum receiver and battery and have a problem with my wing servos and that is that when I use a Y connector to hook the two seperate servos to one lead going into the aileron port both servos operate in the same direction. that is that both sides go up or down together. I have used this exact same duel aileron servo, y connector setup, same receiver etc. in another plane and it works just fine. I am very confused now- did I miss something basic here. Here I thought I was just about ready to break in this new engine and take this plane out this weekend.
