True, in fact proper set up is so important as well as correct CG that I have started putting digital servos in my planes and what a difference it makes. I am striving to get my airplanes to fly like the ones on the sim. I can tell I'm going in the right direction. It's a very time consuming and frustrating process though. I can't wait to start using the flight instructor portion of the G4, there is a lot of good information on this sim. Well worth a couple of hundred bucks!
