20KG RC Servo High Torque Servo Motors, Waterproof Full Metal Gear Steering Servo for 1/6 1/8 1/10 1/12 RC Car Robot DIY, Digital Servo with 25T Servo Horn, Control Angle 180°

I installed this servo in a 2wd Traxxas Slash for my son. Very easy to install, Great quality, very powerful. The noise seems about average. Compared to more expensive servos this is a very good value for the money.

Good looks and good build. It works very well. It has an advanced PWM programming option with Arduino, a nice touch considering the price.

Great servo and affordable

The media could not be loaded. Direct replacement minus some minor trimming on the ears since its reversed on the mount in my build. Works great but is a little slow as you can see but its got good power which the previous 9kg servo was lacking.

I guess I got a bad one. On my servo tester, which works as expected with 4 other servos I have, this one did not responds as it should. I have never seen another servo act likes one did. When doing a full sweep it would very slowly rotate, one step at a time and take almost 2 minutes to rotate about 150 degrees, then it would quickly rotate all the way in a fraction of a second, just like all my other servos do. I tried different voltages from 5 to 8 volts and two different servo testers with the same results. Sometimes, if asked to move by a small angle, say 10 degrees, it would behave normally. However when asked to move 30 or more degrees, it went into this ultra slow step-by-step mode. I was monitoring current and voltage (HP power supply) and it wasn't drawing excess current or causing a voltage dip. I have no idea what it was doing in its ultra slow mode. It was as though the controller was telling it to rotate by 1 degree every second or two - but it wasn't. All my other similar servos rotated normally.It looks nice, it arrived quickly wit all the advertised accessories. It just didn't work right. I returned it for a full refund. No problems. I didn't try a second one and if I had, maybe I would have gotten a good one?.Who knows. Butthis one was a dud.

Very strong servo had a large turning radius and fit in my Traxxas rustler perfectly and had no problem fight the pressure of turning at 50+mph (had a lot of power) definitely would recommend! the noise however was very loud but didn't bother me much with the cover on. control was great was able to move very fast to where I wanted it to go! and the 180-degree turning range was just amazing, again would recommend!

It does not work normally with Arduino but it can work. The sweep test program worked but if you try to just give it a target it does not. I modified the sweep program to increment the position 1 step at a time to reach the goal and it worked great. Seems odd that it won't move directly to position but since it can be incremented to position it is just a few extra lines of code. Am making a remote door opener that pulls down the handle to unlock the door, needed some torque to get it done and this servo was able to do it.

Really nice servos. Quiet and smooth movement. Will be ordering more soon. Great price and delivery as well.
