6PCS MG996R Servo Motor Metal Gear Servo Motor Torque Digital Servo Motor High Speed Torque Servo Motor for Smart Car Robot Boat RC Helicopter Compatible Arduino Raspberry Pi Project

Good price, they do the job.Been using them in my FourStar 54 for a year, no issues.Update: Now the second season of flying with them. Still not one issue or failure.

Everything is cool

needed a couple for a rc warship and didn't feel like hooking up a BEC.... it works great so far

Very strong. My hand could not stop this servo. Only wish it could controlled rotate 270 degrees....but you get what you pay for! Good value overall. Would recommend.EDIT: a few months later, and I managed to brake one of the motors. It's not their fault, though, I applied more voltage than it was rated for (I gave it a staggering 100W!), because i'm too curious. Probably gonna buy a replacement and be more responsible with this one :}

Other reviews said buyer beware ,about the all metal gears being plastic. I opened up two of the servos I just received and both had an all metal gear train, no plastic. Makes them a really good deal for the money.

I bought lots of these for a robot, but unfortunately many of them don't work

Don't know if they are water resistant

So far these servos have exceded my expectations for the inmoov robot hands, seem to give him plenty of a grip on objects. 6 pack was perfect for these.
