MKS HV737 Servo – 10.2Kg.cm 0.09s 38.5g 15mm

The MKS HV737 High Speed Servo is designed for glider rudder, elevator, and V tails, and is perfect for many high performance gas, jet, and electric RC planes. The speed, strength and precision of the HV737 is astonishing.

The gear train uses a new type of gear structure, giving negligible backlash and an even longer service life. The MKS HV737 is powered by a substantial 12 mm diameter x 20 mm length efficient coreless DC motor. It can operate with supplies from 5.5V to 8.4V, allowing the servo to be used safely from an unregulated 2S LiPo battery. The feedback mechanism uses a 9 mm 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 HV737 uses a Futaba 25T spline on the output shaft, so a Futaba metal arms can be fitted, if required.
