This is the Hitec HS-645MG High-Torque Metal-Geared Universal Servo. These metal-geared high-torque servos work great for steering servos. The connector is universal, so it will work with JR, Hitec, Futaba, and current Airtronics radio systems. This servo puts out 133 oz/in of torque at 6 volts! This is great for cars, trucks, boats, and airplanes.
Unbreakable MP Gear
The heart of the unbreakable geartrain is the MP Gear. The MP Gear is made utilizing a revolutionary production technique that injects a high impact plastic around a metal pinion gear to form an unbreakable first gear. By utilizing this gear Hitec has succesfully reduced the amount of drive train noise that is common in metal gear servos and at the same time added considerable strength to the geartrain.
