The all-moving Supra stab is aerodynamically balanced, so the stab servo loads from the airload are minimal. The only loads the stab servo will see is due to the inertial load when the boom "cracks the whip" in the zoom. I have no idea what the associated accelerations of the tail might be here, but let's assume the tail is accelerated vertically at 100 G's. The 1 oz stab then "weighs" 100 oz. Since the stab's CG is about 0.5" behind the pivot, the hinge moment will be 50 in-oz. With the typical 2:1 horn length ratio for an all-moving tail, this translates to Stab servo moment = 25 in-oz But again, the crucial assumption here is the 100G vertical acceleration of the tail. No idea what it really might be. It could probably be estimated from a high-speed telephoto movie of the zoom seen from the side. RCSE-List facilities provided by Model Airplane News.
