MKS DS6125 Mini - discontinued, replaced by MKS HV6130

I needed to replace the hitecHS81 aileron servos for my Reichard SVIST thermal soarer/warmliner and since I had already fitted one of these MKS 6125 mini servos in the tail for the elevator I had no reservations about putting these into the wings. Excellent servo with good centering - highly recommended

Very good equipment, great shop, fast shipping, you can trust.

As I have come to expect, the service from Hyperflight is first class, with a replacement for the MKS 6125 Mini, arriving next day from being ordered*****
However I do think these servo's have issues, that talking to other flyers have come to light. I had to replace this one that suddenly decided to behave in a very un-flyable way, by losing it's neutral position from when last flown coupled with a lot of jittering around neutral position.
Had to buy another due to it being fitted to a built up wing that means being able to fit between the rib spacing.

A very powerful gear train. I use them for flaps them on sailplanes under 2Kg without issue. Only one problem in five years and that was my fault not the servo's.

Awesome servo, but very delicate with tensión issues (2 already blown due to NiMh cells well charged) Would reccomend voltage regulator to keep within safe limits...

Best servos ever made

Yesterday I recived the 2 servos .They are a true masterpice . I buithem as a replacemant for my S 3150 in the flaps of my Supra . I think I made the perfect election.

They are beautiful strong and fit them into F3F ELDORADO from Jaro Muller.

Fast and highly accurate servo. The mechanical design is perfect. But with a weak engine and a cheap motor. I do not know whether to recommend it. Maybe I fly too fast;)

Un très bon servo rapide et très peu de jeu, même après 1 an d'utilisation en competition.
Le boitier métal permet une fixation pratique et solide dans les ailes fines comme celles du Supra.
Un excellent servo.

I have been using 3150 servos from Futaba for years and they are great but the MKS is a jewel, same size (although thinner), stronger, more precise, no backlash in gear train, and a much better way to install in wings.

Highly recommended

Excellent servos with a tight slop-free gear train and plenty of torque. I've found them to be particularly good for large flaps on Open class e-Soaring models. Not the cheapest servo around, but definitely one of the very best! Highly recommended.

I thought I would give these MKS servos a go as an alternative to the usual Futaba 3150 and Hyperion DS095 servos I have been using of late.

I was not disappointed. They have zero slop and are super strong. I have yet to break one (which is impressive as anyone who has seen my flying will testify).

The certainty of hitting the same zero position each time you come out of thermal or speed camber is a great bonus and a slop free servo means one less thing to worry about by the time your control gets to the control surfaces...

Over all - a great servo.

Even though I have a full compliment of 3150's ready I will be getting another set of MKS servos to fit out my new Stork 4 when it arrives. :)
