Jim,

Thanks for the input.

I am begining to think you may be right on the servo here. I have alot of movement in the shaft of the servo with the supplied connections...it seams to be pretty high relative to the top of the servo which is putting a pretty good load on the the output shaft. The JR's must be stronger here.

As far as speed goes, I am running a Saito 91 with a 14x6 prop and get the flutter just after lift off and at anything above 40% tthrottle...so far all I have been comfortable doing is basic loops and rolls to see how the elevator is going to react.

By the way, how do you have your 100 mounted...sidways or inverted?

Thanks again.
Eric
