Description
The MKS HV747 High Torque Servo is designed for glider control surfaces and is perfect for many high performance gas, jet, and electric RC planes. The speed, strength and precision of the HV747 is astonishing. They were used on Mr Kuo Ping Lin's record breaking F3F glider racing flight.

The gear train uses a new type of gear structure, giving negligible backlash and an even longer service life. The MKS HV747 is powered by a substantial 12 mm diameter x 20 mm long high eficiency coreless DC motor, and can operate with supplies from 5.5V to 8.4V, allowing the servo to be operated safely from an unregulated 2S LiPo battery. The feedback mechanism uses a 9mm VR ultra high resolution potentiometer, to ensure the servo moves very accurately, and holds its position 100% when adverse torque is applied.

The MKS hallmark CNC aluminium alloy case adds rigidity and crash resistance to the servo. The gears are pre-loaded to remove all slop or backlash from the geartrain, allowing a level of precision unequalled by other manufacturers. 

The extreme reliability and performance of these servos also makes them very suitable for use in film and motion picture industry special effect departments. They are also used in robotic, drone, UAV, UAS, academic research, military, and other highly demanding applications.

The MKS HV747 uses a Futaba 25T spline on the output shaft, so a Futaba metal arms can be fitted, if required.
