I have to ask what was the linkage setup like? Unless you have really strong digitals, I hope that the clevis at the surface was attached at the end of the horn and the linkage at the servo was attached towards the middle of the horn. Leverage plays a big part in how much a servo will take. You have to be careful not to overload the servos. With such big emphasis on 3D type throws, a common thing I see is to have the servos installed with horns set up for the most throw. THis will most likely give the servo the least amount of mechanical advantage and will contribute to rapid failure of nylon geared servos. I had a Sig CAP and installed metal gear 645 hi tecs running on 6v instead of 4.8. The tourque rating was around 75 oz in. These were on my ailerons, rudder, and elevator halves. I did not have a problem with flutter on any of my surfaces. The Cap had a Saito 180 up front. All I am saying is to examine the geometry of your setup and make sure to give the servo as much mechanical advantage as possilbe.
