KST X10 Mini Wing Servo - 7.5Kg (104.16 oz in), .09sec - High Voltage

If the X10 is physically too big and the X08 is too low on torque the X10 mini might be just right.

The X10 mini, like it's bigger brother, the X10, sports an improved motor controller that's driving a coreless motor which is in turn is spinning a minimal backlash, hardened steel, dual ball bearing gear train, all cased up in a 7075 aircraft aluminum, billet machined enclosure.
