Here's what it says in the manual:

If you are using a computer radio with expo, we suggest that you run 100% expo on the ailerons and about 60% on the elevator.
(we are using full available throws. you may not want to use as much when you first test fly).
A good starting point would be 3/8" throw up and down for ailerons and 1/4" for the elevator both up and down
(if you use a heavier engine which brings the CG to the forward limits, go to 3/8" throw on the elevator).


with that said, i have about 1 and 1/4 inch throws , but like i said before,, USE A TON OF EXPO~!!

good luck , and hit us with your flight reports....
