RE: Are there different ways to set up Dual elevators w/o y harnesses?
Another way would be to use Hi-tec digital servos and reverse the direction of one via a programmer. THen all you have to do is use a simple "Y" harness. No mixing to play with just plug & play. If you do not want to pay for the programmer places like servocity will reverse the direction of a servo for you.
I hope that helps!
