This product has been replaced by the KST X10-710

The KST X10-710 is a drop-in replacement of the DS145.

It is an improved servo with a better specification.

The KST DS145MG is an amazingly good metal cased servo, suitable for glider fuselages, and helis, and all RC models. It is exactly the same size and has 90% of the performance and build quality of the market leader, for 40% less. Like the more expensive servo it has no geartrain slop. Unlike the other it comes with a well fitting anodised alloy output arm.

At only 10mm thick this great wing-servo can easily fit in thin glider and jet wings. With a massive torque the KST DS145 is appropriate for F3F, F3B, F3J, F5J, all fast gliders, 450 and larger helicopters and jets.

I bought 2 of these off Neil for my Nan models Orion and wow, value for money, amazing!

Brilliant servos, powerful, no slop and very efficient.

They fly my machine around like nothing else I have had before.

Nicely engineered feel, and efficient

Fast delivery, much appreciated. I really like the solid engineered feel of these servos. In my "wing" glider, 2 servos use up very little battery power - my experience over many outings is that 2 typically consume 155mA per hour in total, which is great for those wishing to use smaller capacity batteries for space/lightness reasons, or just enjoy plenty of hours flying between charges.

Ideal for very tight places and reasonable grunt at 5.2Kg
very nicely made.

Good servo, very precise, powerful and light. Costs half of other servos much lauded with the same characteristics.

KST DS145MG Servo

This servo is perfect for use with the JR Axis Gyro. It is powerful enough for all but the heaviest use. It's low profile allows it to fit within a wing or deep narrow fuselage.
Service from Hyperflight was exemplary and could not have been bettered.

Kst servo Ds145mg

Great price, fast service. Very smooth and positive servo. I have great confidence in these and have not had any problems with them in any shape or form

 Review by:

i bought these to use in a 3D model (using a 4S power system) that had large surfaces that moved to extreme positions - hence i needed servos that would provide power , speed and high resolution . I was dubious that a £25 servo could meet my reqts however reviews from other pilots advised they were worth a look. Having now fitted these servos to the model i can advise that they meet all my reqts and even with extended arms on servos there centering is spot on . There is no servo hum at neutral , speed is superb and they provide a really tight link to all control surfaces . i have used the metal servo arms supplied , these ensuring a solid link to all control surfaces . torque more than adequate for my model , in future i will use these on larger model (6s ) - highly recommended

 Review by:

I have been a modeller for the past 45years and have tried lots of well known brand servos over this time. I wanted some quality servos for my new camera gimbal for my aeropic quad.I looked rather deeply into the subject to the point of thinking of building my own.
I could not find any servo with zero backlash on the gear train. However I was so impressed by a video i seen featuring these so i decided to purchase a pair.

Money very well spent!

This servo just speaks quality product from the time you pick it up to connecting it to your radio quiet power with a reasonable response. The mounting lugs are robust and the whole servo speaks quality. It is supplied with a lovely quality alloy servo arm and a collection of nylon arms and screws. The alloy arm is a perfect engineering fit to the knurling on the output shaft and requires a perfectly true pull to remove it. This quality of engineering I like.
I will be purchasing more of these servos in the future for my larger models
I only have one negitive thing to say and its so minor i was not going to mention it the mounting lugs are bored for a 3mm threaded screw But there is not enough free space against the casing for the head of a 3mm threaded pin either a allan head or dome head to fit without taking a little from the diameter of the screw head However having said this, I highly recommend this servo if you require precision and like quality engineering and a servo you feel you can trust
