Dart, I had to use the reversing y to connect the flap servo's. The ailerons go on channel 1 and 6 and you enable the flaperon fuction. The Futaba manual with you radio explains this pretty good. The flaps with the Reversing Y go on channel 5, the gear channel. This lets all the servo arms point towards the wingtips like the examples in the Ultra stick instructions. For Crow I put the flaps down with the gear switch and ailerons both go up with the airbrake switch. I am sure there are other ways to do this and get the same results.
