Oh sorry I forgot you're doing a Pitts....I have a Pitts Python...I cant remember if I Y'ed the 2 lefts together and the 2 rights together or if I Y'ed the tops together and the bottoms together...I'm pretty sure I did the top to the top and bottom etc. in that case use 2 channels or you can get a servo matcher....a servo matcher is just another item to fail.....
Have you given any thought to the optic kill switch? or and the choke servo.....A friend of mine was almost killed by a gasser that didn't have the kill switch.....
