JDHammer,

You must remember that the control surfaces are quite powerful, especially the rudder. 1/2" could be alot or not enough depending on your abilities. I would suggest putting dual rates and adding expo on your high rates. 1/2 sounds like a good starting point for high at the moment. I will be interested to hear about your first flight. BTW, what does your airplane weigh and what is your engine choice?
