And if you want a little more torque try the Savox 1230SG 499.9 oz of torque out of a standard size servo for $69.95
Hey John, put in the new 500 1230sg for rudder in my F rigger, good luck trying to hold the rudder while U turn the steering wheel, will rip your hand off, super strong,very smooth, I have a servo tester I built about 18 years ago, just hooked it to 12 volt motorcycle battery, mounted into a 1/4 inch aluminum servo holder, bolted to 2/4 side was, used metal arm, ran a metal 3/16 threaded rod down
to a, 5 1/4 pound of pie steel, hanging 4 inches of the floor, servo tester has 3 speeds, slow, medium fast and high, which moves the arm from end to end in 1 second. I just wanted to test the longevity of the servo so I set the servo tester on medium, pushed the batter switch, and watched that servo sling the 5 pound ball, back and forth, for 1 1/2 hour with out stopping, once or missing a lite. The diode lites, lite up individually as the servo goes from one end, to the other end. I finally got tired of watching the back and forth, well have to try it in the white whale soon, maybe it will tame it down some. John I made it back on IW, Yaaaahooooo.
