What's interesting about this is that no matter what leads to where, if the ailerons are set up correctly, they will work correctly no matter what leads get hooked up to what.. left to left.. or left to right.. doesn't matter. At first, this is a bit confusing, but a little thought tells you that the signal leads are common.. (as are the power leads) so it doesn't know nor care what it's hooked up to as long as it's hooked up to aileron servo leads.
