This set is good for its small price, the regulator is a very nice item for adjusting the speed of the drill. I just needed to apply some very soft grease to the motor bearings, before i did it, the motor caused bad vibrations at the higher speeds. After greasing, it runs smooth. The motor is a 12 Volt type as you maybe know it from some FP-helis or bigger coaxial helis. Looks like a Mabuchi 360. Very nice tool for drilling holes for servo mounting into plywood, shortening your pushrods, grinding some small surfaces. A must have for any modeler.
