With this setup it doesn't matter which lead goes to which servo. The control surface movements are correct connected either way
althought I use a Tracker II , this is not true for my 2 servo set up for ailerons. If swithed around, the servos move in the opposite direction. I also use channel 6 in order to mix in flaps.
I don't want to spend a lot of time troubleshooting this but I think it works with any reciever. Because each servo is driving in the opposite direction when the leads are reversed (and thus the input impulse is reversed) the movement of the control surface comes out the same direction. I've done this with two planes now and it works fine.
