RE: Dual Rates and ATV's?
ON my Carden 330 I have one 8611A on each half. I setup the ATV at 140% on the 10X radio. full up and down deflection is 20 degree of throw. I used dual rate to set my low rate.
I also added 3/4 of lead to the counter balance of the elevator(advise received from Ivan Kristensen). This setup was worked great.
