The
MKS HV6120H servo is the latest servo from MKS aimed at the F5J and light large glider market. It has normal mounting lugs suitable for fuselage mounting. It is more powerful, faster, and considerably more robust than the DS6100 and HV6100 servos, and operates over a wide voltage range. It is rated for operation down to 3.5V making it safe for use on 1S LiPo batteries and up to 8.4V making it fine on 2S LiPo batteries also.
The HV6120 is ideal for F3K, F5J, F5D, and all small models that require excellent precision, massive torque, and adequate speed. It is possibly the best 8 mm thick servo produced so far. It looks beautiful and with a torque of up to 5.4 Kg cm it is amazingly powerful.
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.
