4-Pack Servo Motor MG995 Control Angle180 Metal Gear Servo 13KG Digital High Speed Torque Servo Motor for DIY Smart Robot Toys RC Toy Car Model Helicopter RC Boat

Price was awesome for 4 fast Metal Gear 20KG Servos! worked perfect on two of my 1/10 crawlers both with rear steer definitely an upgrade over the 6KG stock,

Good servos tested well at 5V

I got these servos to use for a small electronics project (completing a 100 jump challenge in Mario RPG, haha). It was a fun motivation to gain a little experience working with electronics hardware.My first attempt used a little 5 volt 2 amp power supply I had laying around, and wired directly to a Raspberry pi 3b. But it turned out this was not nearly good enough, as the servo would move erratically or not at all. I upgraded to a much stronger variable voltage desktop power supply and put a proper servo controller between the Pi and the servo, and then it worked great. There are wiring diagrams on adafruit and tips on reddit. The best way to learn is to try!

These aren't the best servos you can buy, but they might be the best you can get in this price range.I bought 20 of these to build a hexbot; overall they work OK. They're a little noisy and loose and sloppy in their control. I had 2 fail (lock up/burn up) and probably 2 more with positioning issues that cause them to oscillate when they should be still.All that being said they're "good enough" - I'll forgive a lot of these sins for the price point. With the better alternate being 4x the cost, they're cheap enough I can buy extras to swap out the ones that have issues.

Replaced my spectrum 600 servoPerfect fitMy 7yo has not killed this one yetBut I have 3 spare , all for less then 1 oem metal gear

Estos motores me sorprendieron, los elegí principalmente porque sus engranajes son metálicos, lo cual les da una vida útil mucho mayor que los de plástico. Los usé en un proyecto de electrónica donde se requería bastante fuerza, y respondieron muy bien. Funcionaron sin problemas, con buen torque y precisión. Perfectos para proyectos exigentes. También mencionar que trae piezas extras.

Thus far, the single servo I've put to use has only been used in one test flight, so I don't know if there are any longevity issues with these servos. What I can tell you is that the ones I received are branded "Deegoo FPV" and all the gears are metal. I've seen other reviews mention plastic gears, which I was okay with when purchasing, as I needed cheap servos for my project. The photos of the servos with plastic gears have a different name on the stickers than mine do, so if you order these and they don't say "Deegoo FPV", they most likely have different gears, and I'd return them for replacements.The only con for me, is the grease seeps out of the casing, and can leave grease marks in a toolbox or plane. But at least they're lubricated!

The information on the product page says "Metal" and "Metal Gear". This is misleading, as the Servo is pure plastic and there is only one metal- gear among the gears. All the rest of the gears are not metal, they are cheap plastic gears that break very easily, causing the engine to run idle. I tried two motors, both brake with less than 7 kg/cm force. I bought this brand a couple of years ago and they were fine. Now they have changed to cheap junk. Not worth the money. I tried to reach the seller - no way...
