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.

Low/standard voltage versions of the DS75K are available with standard mounting lugs (the DS75K), wing mounting lugs (the DS75K-R), and no mounting lugs (the DS75K-N). High voltage versions are available with standard mounting lugs (the HV75K), wing mounting lugs (the HV75K-R), and no mounting lugs (the HV75K-N).

Servo replacement

I have recently replaced the elevator servo in my Sprite with the MKS DS75 K , although rather expensive what a brilliant result. Service from Neal as always absolutely brilliant.

Great servo. Stands in ailerons, flaps and Elevator on Hyper2,3. The second season works without complaints. No backlash and perfect centering !
Good store service and fast delivery !

Elevator servo

This is my second MKS DS75K. Although expensive it will probably last long enough to justify the cost. Very well made - strong case, no slop in the drive. Excellent power output for the size and weight. The low height is one of the biggest selling points - it can fit in tight spaces such as the rear fuselage on the Knief Racer.

Recently became a MKS user and wish I had sooner. These DS75 are amazing. So much smoother and quieter than the KST I was previously using. Absolutely no gear play, definitely worth the price. Only negative I'd say is the short leads, they are shorter than the SD100. Although for installs close to the rx it's not a problem and keeps things neat.

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.
