4Pcs MG995 RC Servo 20kg Metal Gear Servo Analog Servo Metal Gear Servo High Speed Torque Digital Servo Motor for Smart Car Robot Boat RC Helicopter(Control Angle 180)

Llegaron muy cumplidos, cumplen muy bien su función en vehículos Tamiya truck.

I purchased these to automate my ham shack a bit. Blinds, A/C registers, stuff like that. I’m disabled and these will help out a lot. They have plenty of torque. My daughter tried to stop a servo. She didn’t have a chance. She’s no lightweight either. She snapped a real Craftsman socket when she was 15. They’re easily converted to 360° rotation. With metal gears, several arms, spacers and screws for the price, I’m impressed!

When I ordered these servos, I only needed one, The price for 4 was very attractive, so I decided to get them and have 3 spares for future use. While waiting for the parts to be delivered, a steering servo failed on a different car. So, I have installed 2 of the 4 servos and they work fine. I did test the remaining 2 servos and they work too.

UPDATE: After ~5 hours of total use, 3 of the 4 units have failed. The servo pots are not functioning and at the end point of travel, the servo keeps "searching" meaning it continues to move back and forth when the transmitter is held at the end of range. I will be removing these servos from all my cars and trucks.For the price I was not expecting high quality units. They function and rotate as advertised, but the biggest issue is that fit does not center consistently. This becomes a major issue when racing at speed. Imagine coming off a turn heading into the straight and slamming into the wall instead at high speed. It's not a pretty sight.For low speed rock crawling, it works great due to the high torque.Overall it works as a servo should, but not consistently.

The media could not be loaded.  I used this for an "automated" Trick or Treat shute, and it did the job. It seemed to have a good amount of torque, and it felt pretty sturdy. It was compatible with the arduino 'servo' library!

Came quick and work. They are definitely cheap as I have to replace them often on my rc car because they break.

Two of the 4 work perfectly, the other two also work buy are much noisier and feel a bit rough. Not sure if they'll stand the test of time, but we'll see.While you can physically rotate the servo a little over 180 degrees manually, when it's being controlled by an rc receiver it will only rotate 90 degrees total. That's 45 from center position in either direction. This is pretty normal as the PWM range of RC equipment limit's the movement. If using an Arduino you'll probably get the full range. You can also solder in some resistors to extend the movement range - google it.

I needed some high torque servo's to replace the old ones in some of my rc cars. They seem to have more torque then the old ones, the only thing about these you have to figure out what way to plug them in so they move the right way there is no direction limit on them if they operate the wrong way then flip the plug.

All was good. It arrived in good time and no damage.

bought it because the gears were all metal, but the gears inside are plastic. I bought it today and opened it to see if it was cheated. Please return it

Most of the servos worked well, just one couldn't do a complete 180 degrees, more like ~160

So far I have tried one of them and it is working better in comparison to other low-cost servos I had. They are larger than the similar servo type which scared me in the beginning. but I ended up using the same power (I am using 4x NiMH).I believe do due to the relatively better quality of the material used in the gears, it is carrying the load smoothly (relatively). I am not sure about the electrical component though. Jitter sometimes appears. This can be due to issues with the servos themselves or my controller. It was not possible for me to confirm which one is the case.The packaging includes servo horns of different sorts. It even includes self-screws which are very useful if you want to attach to your 3D prints/wooden parts. The shaft has internal metal threads which means that you can connect the horn properly to the motor (not like cheap plastic threads).
