Yahboom 25KG High Torque Digital Servo Full Metal Gear Servo Motor for RC Model DIY Waterproof Control Angle 180° DS3218MG (25kg servo)

OK so, I have tested this on a few rigs... A slash, stampede and a trx4. Real quick ill say, No, it is not suitable for any serious rock crawling. And will likely not stand up to an inexperienced child or otherwise making mistakes with trim and cramming it too far to one side. It IS better than the stock trx-4 servo. That all being said, it's great when paired up with a trusty servo saver. It's quick enough, has all metal gearing and is as easily serviceable as a servo gets. The stampede with its larger 2.8 wheels tested it best, I made sure to land completely wrong from heights and with speed that would be considered generally abusive. The thing still works just fine. Bottom line: it's a great cheapish servo with plenty of torque, speed and durability for your garden variety entry and mid level bashers. So one star knocked for overall value as the servo horn and other bits included will be almost completely useless for nearly all using this as a steering servo in a vehicle. If you have a use for this servo and the included other bits, you probably don't need my advice... Yea whatever, it's cheap, neon green and works.

Works great for my brake and throttle on a Baja gaser 5T-love the green arm -as my truck is also Green! Tested on asphalt-all good - truck is built for sand so we will see-battery pack is 5000 5 hump back c -cell 6volt charged up -locks brakes up noProblem..40lbs 1/5 truck

Torque ratings are acurate. The finish and overall construction is very good. The speed is slower than I would like but for the price its decent. I mounted this on my old Axial Wraith that I hadn't ran for years and did the job after my $100 Spektrum took a dump

The short story, you're better off buying the popular 20kg servo instead of this one.Longer story. I while back, the traxxas 2075 stripped the gears in my slash. I replaced it with one of the Red 20kg servos. Worked well, super strong, shouldn't have any issues.Another 2075 servo got stripped in my crawler. Came back to amazon to buy another 20kg servo as I had a good experience with the last one. This green one looks exactly like the popular 20kg red one, and knowing how things are, I suspected they are all coming from the same place. So I decided to pick this one up, give this seller a try, and plus its green which is a little cooler than all the red ones.Unfortunately, it seems these are a cheaper version of the cheap ones.... yeah. But even for the same price. They're much slower than the red one in my slash. The torque is there, but I suspect the gear ratio was setup for torque and compromised on speed (unlike the red which is strong AND fast). It's just about okay in a crawler, a bit annoying but not enough to swap it out. In a faster RC it would be super annoying to have such slow steering.I took a shot with this sellers product. A bit disappointed in the end. Next time I'll be sticking to the better Red servo and make sure I purchase from the main seller to avoid buying a copy.

Every single one of my rc has one of these servos. I probably have 5 more not even pictured that run them as well. Never had one show up bad. Never had one issue with one and these have more than enough power to turn 3.8 tires in any terrain no problem. Will continue to buy them for any new rc I end up getting. You cannot go wrong with one of these!!!

It works great but be careful with your end point adjustments or you will break stuff it’s a really strong servo.

Been running one in my arrma felony. Tons of power and gets the job done. No complaints

I'm sure this will be a good servo for robots. But as far as R/C vehicles go its a no go. Steering is very glitchy. Will not come back to center. Slowly comes back torwards center but no matter what direction it comes back frim it stops just shy of center making my truck veer off. It is a slow servo. Will not keep up with steering my truck. I'm not sure if it's just a bad servo in general. I never had a setvo act like this one. For 25 dollars there are better servos. I'm going to stick with Futaba. They have never failed me.

Fonctionne bien mais vitesse de réponse un peu lent. Pour un crawler pas de problème

Buen torque, buena calidad
