Thanks for the technical description, now, how does one tell if they're overloading their servo (before the servo fries)? Given that even at full 140% deflection of near 90deg at the servo I only get 40deg at the surface I'm not running at 1:1 and the servo is getting the advantage, and using that ratio with the 5925's rating I get 238oz of torque (about 17lbs). NOTE: the axis of rotation at the control horn isn't over the hinge, its a fraction of an inch behind, so you can't really use the length-of-arm:lengh-of-horn ratio, you have to use the deg-of-rot:deg-of-rot as I used above. So, given that, its stands to reason that I could move up from a 1.25" arm to a 1.5" arm and the servo would still have the advantage, no?
