Hi, I'm building a Waco Biplane it has four aileron servos. I have a 10CG radio with a 14 Chanel receiver I have two servos on chanels 1and 7 no problem there. I've been trying to get the other two servos useing the program mix useing 1 and 7 as the master and 6 and 8 as the slave. But I can't get it to work, will I be able to do it with out useing a Y harness. Thank you
