20KG Digital Servo High Torque Full Metal Gear Waterproof for RC Model DIY, DS3218MG,Control Angle 270°

Works as it should, durable, easy to install.

I love these servo, quick enough and plenty of power.

Perfect

It's extra tall, so it might be a tight fit in some RC cars like the Tamiya Grasshopper or Grasshopper II / 2. It only generated 12-15 kg in tests before the recent update on 2025, so just buy one that is double the torque that you need. All that said, it has metal gears, is digital, and is waterproof, and very inexpensive, so as long as you know what you are getting, and compensate for that, it's a good deal. While it claims the brand is Annimos, they are just a distributor of the DSServo brand servos

Awesome project! My 3 year old beats the he’ll out of his Arrma Gorgon now since replacing with this servo after the stock plastic gear junk broke after a few uses. Highly recommend on something light and 2 wd because the slow rate

Works well

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.

I use this servo motor to turn a knob to turn on our old window AC unit. The knob was very rusty and required a lot of force to turn which my old 9G servo motor could not turn. This handled it without any issues.One thing to point out is that the servo.detach function doesn't seem to have any affect on it. Meaning that the motor will constantly try to hold it's position and if something is pulling the motor, it will try to correct it while making an audible high pitch noise constantly. I also wish there were other attachment options. Other than that, this is a great motor!
