Description

The MKS DS75K servo is the latest small servo from MKS. It is more powerful, faster, and considerably more robust than the DS65K. It is also rated for operation down to 3.5V making it safe for use on 1S LiPo batteries. Its clever inverted motor design makes it very compact, in fact it is nearly as small as the SD100/D47 in the vertical and horizontal directions.

The DS75K is ideal for F3K, F5D, and all small models that require excellent precision, massive torque, and adequate speed. Along with the DS65K it is probably the best 8.5 mm thick servo ever produced. It looks beautiful and with a torque of 2.4 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.

A version is also available without mounting lugs - see the DS75K-N

Excellent servo!

Excellent servo!
Almost as small as a Dymond D47 but much stronger!
Height can be reduced even more by using a countersunk M2.5 x 4mm screw for the servo arm.
The servo cables are very short at 67mm! Too short for the rear servos in a 4 in pod F3K install to reach the receiver!

PLEASE make them available with at least 80mm cables like D47 or even 100mm.
This is the wrong place to save weight! You can always shorten the cable if you want but extensions are bulky and some don't want to solder longer cables!
Further at least one or two more servo arms should be included as with many much cheaper servos.
As of today I don't regret paying the high price. I will try to find out how long these last.

I got the old type with the motor cables not covered although the new type with the full metal housing was pictured.

Used in a Stream NXT on flaperon and tails. Excellent on 1 cell. To fit in the NXT wing they have to go 5 mm forward in the milled servo pocket. Totally slop free top drive install. In the fuse it is an easy fit.
Expensive, but well worth the money in my opinion.
Ordered an extra set of plastic horns. Thats the only minus; for the price they should include more horn options.

Excellent but note arm length

Bought these quality servos for a weasel trek but found the supplied arms a bit short in length for the application,so ordered the longer plastic arms which suited the plane much better.
Servo zero,s accurately am very pleased with them.


 Review by:

Excellent servo.
Used them before on rudder and elevator in tweagle td.
Now they are operating the flap in a homebuild 3 m f5j to full satisfaction.
Well worth the money.


 Review by:

Love these servos, fast, accurate and reliable. My first choice for an aileron servo in a DLG.


 Review by:

I use these in my Tweagle TD. Nice fit in the small nose. Powerfull and accurate. They drain the batterie faster than other sevo' though.
