This is the Hitec HS-82MG Metal Gear Micro Universal Servo. Because this servo has the universal connector, it will work with JR, Hitec, Futaba, and Airtronics Z radio systems. These are great for small planes, gliders, electric helicopters and 1/18 scale cars.
Hitec took one of their top selling servos and made it even better. Based on the ultra popular HS-81MG, the HS-82MG gets a new stronger motor and updated electronics for more precise centering. The HS-82MG is perfect for smaller aircraft and helicopters where a durable geartrain is required.
Features: For small planes, gliders, electric helicopters and 1/18 scale cars
