I was always puzzled a little by recommendations to use a mighty servo on the full flying stab. I totally understand the need for precision here (digital servos), but why use a very powerfull servo? If the stab pivots around its aerodynamic center and has a symmetric airfoil (both are true in 99.9% cases, including ICON I assume), then the control moments on the stab are near zero. The loads on the stab servo are miniscule compared to those of a flap servo. Am I wrong here? Oleg. RCSE-List facilities provided by Model Airplane News.
