Review: Used it in 6s arrma fireteam - So I had the 20 kv servo for close to a year and never used it,but my arrma fireteam 6s stopped steering 100% and I was not wanting to wait until the replacement came so I figured this was not going to be powerful enough or hold up, so it installed easily, and looks like it is a factory piece, it's not as fast as I would like, but truthfully it's as fast as the spectrum one and doesn't cost even half of the price, I've ran 2 battery packs and some light bashing and it's still working properly, and the durability of it seems to be well worth the price and even better than some of the other ones that are twice as high, really I don't have any complaints other than it does sound a little bit more noisy than I like but it's probably because it is having to work harder than intended, I think if it was a 35 or 45 it would have not been as loud because it would have not been under as much strain, but for now this 20kg is stronger than expected.

## Questions & Answers

**Q: Does the pulse width need to vary beyond the range produced by a typical hobby receiver to get the full 270 degree rotation?**
A: Yes,you're right! Generally speaking, the output pulse width of the remote control is in the range of 1000-2000,so the displayed angle is 135 degrees;To get the full 270 degrees rotation, the output pulse width should be 500-2500.  :)

**Q: Will this servo fit a traxxas rustler?**
A: Yes,this rc servo can fit traxxas rustler

**Q: What are the motor arm dimensions? What size are the holes in the arm? Are they clearance holes or threaded? Where are the wires located on the back?**
A: Thanks for your question.Servo Arm is 25Tooth,they are threaded.More info please contact with seller.

**Q: my esc has output voltage of 12v can work with 12v?**
A: It's not ok cause the voltage is too high

### ⭐⭐⭐⭐⭐ Durable and responsive
*by J***O on November 29, 2025*

Used for steering in a robot and RC car. Works well, durable and stable.

### ⭐⭐⭐⭐⭐ Great servo with a lot of power for the size.
*by B***L on March 6, 2024*

I ordered this for my HPI Baja 5B because the steering/throttle servo went bad, and I ran across this on Amazon. It was priced really well so I thought I'd give it a try, and needless to say, I'm pretty impressed. I was able to install it without any modifications, and it was a perfect fit. Setup was easy, and it has a lot of torque for its size, and it is pretty quiet. It is well worth the money.
