Mark,

I see what you mean but let me give you something to ponder....Let's say that JR rates a servo at 100 ounce inches of torque measured at 1" away from the center of the arm. Let's say that servo made by XYZ company also lists their servo at 100 ounce inches of torque but the measurement was taken at .5" away from the center of the arm. According to your chart wouldn't the JR servo actually be TWICE as powerful than brand XYZ? If you moved the measured position on the JR servo to the .5" position, like brand XYZ, would it not read 200 ounce inches? This is what I want to know---Where on the output arm do the servo manufacturers measure torque from?

Yes, adjusting the ATV does increase resolution. I was thinking about analogue servos when keeping the servos at 100% of their throw or greater. Digitals produce almost max power even right off of center where analogue servos don't make max torque until they are near max throw. However, linkages also play an important role in "torque multiplication" as Ultra Viper put it. To maintain max leverage on a control surface it is best to put the control rod on the inner most hole on the servo and on the outer most hole on the control surface. (While still maintaining enough control surface throw) Setting the ATV to 125% increases resolution AND allows the control rods to be positioned for the best mechanical advantage.
