JVerified owneron MKS Servos X6 HBL575SL Brushless Titanium Gear Low Profile Digital Servo (High Voltage)

Insanely great servo, with insane specs even more so do to it being the smallest low profile surface servo I am aware of. There are some very, very minor jitters, thus no worries as they only appear when their is no load on the servo (EX: wheels off the ground do to car being held or on a stand) Pretty much minor jitters are the same sometimes seen with some of the KO servo's. The X6 uses 4 pole motor, hence another possible reason for possible jitters. This servo is not only beautiful as again it really performs excellent, being super strong, fast, dialed accurate and able to withstand a beating. Oh! as mentioned I have noticed the minor jitters however when used with a higher end ESC I have not had any jitters.

This gets 4 stars until I can get the jitters worked out of it. I bought a couple of these, they look beautiful and seem to be well built. They are quiet and smooth. They actuate very precisely and can rotate completely. Most drop in washers don't fit as the mounting holes are too small. Not a big deal if you want to ream or drill them out. I'm waiting on android programming that is supposed to come out this new year. I was told by mks that I can tune the jitters out and that they would work just as any other servo. Apparently this has to do with bandwidth I was told.

This thing is butter. I had the HBL550LX ($100 one) in my car and was completely happy with it- you can see my review. But my son needed a servo so I gave it to him. Amain was out of stock so I got this HBL575SL and wow. It is the smoothest and most quiet servo I have ever used, or seen. As far as torque and speed go, I can't tell the difference in a 1/10 car. MKS spec's. this one as slightly faster and stronger. I used to spend $60-$85 on Savox, and then worry and wait for the inevitable problems. If you have the budget to spend $150, buy this. If not, get the $100 MKS. Either way, your getting your $$$ worth, and a far superior product: function, reliability and finish.

Great servo, I use these for both 1/10 on road touring cars and 1/10 off road buggies. Fast, precise and quality build.

Jim GlasgowVerified ownerMay 7, 2026on MKS Servos X6 HBL575SL Brushless Titanium Gear Low Profile Digital Servo (High Voltage)

Hands down my Favorite Servo for Dirt Oval, Sedan, and Offroad. The MKS X6 HBL575SL are in all of my cars. Servo is rock solid and bullet proof. Transit times are fast, precise, and the servo centers perfectly every time. Nothing better out there than MKS Servos for 1/10 scale in my opinion.

What reviewers say

Reviewers generally rate this high-voltage low-profile titanium-gear servo very highly, praising its speed, precision, smooth and quiet operation, strength, and build quality across 1/10 touring, buggy, and oval applications. One reviewer notes it is among the smallest low-profile surface servos they know of. The main recurring issue is minor jitter, which one owner reports only when the car is held or on a stand with no load; the owner was told by the manufacturer this can be tuned out, with the fix linked to bandwidth and pending programming software. Another reviewer reports that most drop-in washers do not fit the mounting holes, requiring reaming or drilling. One review compares it favourably with the cheaper HBL550LX and notes the price is higher.

  • + Fast, precise and accurate response
  • + Smooth and quiet operation
  • + Strong and durable build
  • + Compact low-profile size
  • − Minor jitter with no load
  • − Drop-in washers may not fit mounting holes
  • − Higher price than some alternatives
