MKS HS75H Hall Effect Servo - 4.0Kg.cm 0.09s 7.9g 7mm

The MKS HS75H servo is a 7.5mm thin high voltage servo with a hall effect (magnetic) position sensor, for maximum resolution and reliability. This version has normal mounting tabs making it suitable for fitting in a fuselage.

The MKS HS75H is ideal for F3K, F5K, F5D, and all small models that require excellent precision, massive torque, and adequate speed. It is probably the best 7.5 mm thick servo currently produced. It looks beautiful and with a torque of 4 Kg cm it is amazingly powerful with an excellent 0.09s/60 deg speed.

The supplied accessories include a pulley type output disk, making this servo ideal for pull-spring tail surface connections, as popularised on DLGs but also finding favour in other classes of models. Although old school modellers are reticent about trying pull-spring it is actually very quick and easy to set up, and results in a lightweight and totally slop free control surface linkage. Easily implemented using our torque springs and pull cord sets.

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.

This servo is also available with wing mounting lugs, see the MKS HS75.
