I'm at a stage where it's time to juggle the components to come up with the working CG. What do you know about those GWS servos? The guy at the LHS says that the GWS servos with 19 ozs of torque would work OK. I have had so many problems with HS 81s with poor centering and stripping gears, I think it is time for a change. The HS 85s might be the best choice here, but I would like to know if any of those dirt cheap GWS servos can work just as well?
