I have been reading a little about utilizing flaperon and spoileron functions. I would like to try to set this up to get faster descent rates on elevators and help settle out some wing rock but I cant seem to get it to work on my Futaba 9C. I THINK that the problem is the ailevator function used to operate separate elevator servos. Is there another way to set up my separate elevator servos in my transmitter without using a Y Harness so that I can use these functions?
