Speed and accuracy combine making this T-120 Lo-Pro Servo a perfect choice when precision and quick reflexes are at work. Designed to give you the industry’s highest per degree resolution steering and plenty of speed to keep that chassis where you want it.

Full Metal Gear set, All Aluminum Housing, Digital Position Encoding and loads of Torque, this servo keeps you in control. Fine-tune your setup with an extensive set of adjustments via Tekin’s HotWire PC Interface (TEKTT1451).

The Difference is in the Design
Tekin servos are crafted from the highest quality materials available. CNC Precision Cut gears provide an extremely smooth and efficient drive train. 6061-T6 machined aluminum 3-piece o-ring housings provide strength and protection from the elements while the finish quality and design are second to none. Sleek chamfered edges and bold lines combined with a matte anodized finish are sure to accent any build.

Included with the T-120 Lo-Pro Servo is a machined aluminum Vector 25T servo arm.

Advanced Technology:

  • Digital Magnetic Position Encoder (DPE): Our servos use Digital Magnetic Position Encoding (DPE) rather than a standard potentiometer, which gives Tekin servos industry leading accuracy, linearity and consistency.
  • Accuracy: Precise linear movement through the entire motion range with less than .2 degrees of deviation from start point to end point make Tekin the superior performance product.  Low deviation DPE technology translates to pinpoint accuracy not found in other potentiometer servos, which tend to wander and center poorly and get worse as they age. Tekin is built to last at peak performance.
  • Linearity: Potentiometer servos can be up to seven degrees non-linear from end point to end point, creating a disconnected feel from your transmitter. Tekin servos eliminate this disconnect, giving you a linear feel and more precise control over your servo movement and position.
  • Consistency: Performance is important but we are all about consistent performance. Potentiometer performance drifts due to many variables; heat, age, component quality, etc. DPE is a rock-solid, repeatable and consistent technology bringing an unmatched consistency to Tekin servos. Tired of constantly trimming your servo and having response feel different during times of longer usage? Tekin servos are the answer.
  • Efficiency: Accuracy drives efficiency. A servo that has to work less to center or stop without overshooting position is using less energy. This means less heat build-up, less component fatigue and longer life.
  • Adaptability: Tekin Servos come with a series of unique features; DPE technology lets you set the center point anywhere, and servo travel limits can be set without reducing the End Point Adjustments (EPA’s) on your transmitter.  Most servos are limited to 90° travel in each direction with a physical stop point; DPE means that Tekin servos can be programmed to travel beyond 360°-- up to 5 full rotations in each direction!
  • Element Proof: Dependable, no matter the terrain. Element Proof Tekin products are designed to handle water, mud & snow within reasonable restrictions. While we are not afraid to take on the elements, submerging is not recommended.

The only reason I have not given this servo a five-star is due to the very weak aluminum servo horn twisting after three packs. I'm using this servo in my TLR22x-4, so it's not like I put it in anything too demanding.

Exceeds expectations. Love being able to program separately outside of transmitter settings and especially reset zero. Only complaint is Hotwire programing for servo is only PC at the moment. Hopefully soon the iPhone app is updated to add compatibility so I can leave the laptop at home. Otherwise, would be hard pressed to find a truly better servo line on the market.

Tekin T-120 Low Profile Digital Hi-Speed Programmable Servo (High Voltage)
Purchased with and installed into my new Associated B6.2 a couple months back. After using about 20 Protek servos in every other rig Ive built in the last 2 years, several 170SBL's, 170TBL's, a couple 370TBL's, 3 160TBL's, 2 160SS's and several 160T's and never having a single issue or complaint, it was difficult to buy something different haha, but I will say that the finish quality, appearance and performance is as good or better than any of the 3 different low profile servos I have in other vehicles from the other brand. This one is more expensive, but Im definitely going to try some full size versions in some of the bigger vehicles Ill buy going forward as they will match the Tekin ESC's and motors that I use for every 1/8 rig I build. I really like how the servo continually rotates so the horn can be installed anywhere and the servo can then be centered to make it work. It was odd at first being able to just wind the horn all the way around non stop, but it actually makes more sense to do it this way. Lastly, once I saw the servo in person I wasnt aware how nice the aluminum case machining is. These servos are awesome looking!

Possibly the sexiest looking servo ever created.
I'll take two they're small.
Strong, plenty fast and too early for longevity test.
