Review on Longruner 10X MG996R Metal Gear Torque Digital Servo Motor For RC Model Car Boat Helicopter - LKY62 by Harry Ashcraft

I bought 20 of these for a Hexapod robot build that needed 18 of them. At around $4.50 each this was an enormous cost saving over other servos and made the Hexapod build possible. I've run these continuously at 6 volts and have them moving as fast as possible and they do their job outstandingly for this kind of project. For the Hexapod I don't need good accuracy or repeatability, so if those things are an issue with these servos then I don't see it, so I can't speak for it.However, it is now 2 1/2 months after my purchase and a third servo has gone bad, stopped moving, dead just like two before it, and now I'm out of spares. So maybe run them at 5.5 volts and maybe not at maximum speed all the time and perhaps they'll last longer?Also taking a dead one apart, you discover the servo shaft visible from the outside and it's gear are made of brass, but all the other gears are plastic, so "metal geared" is a little misleading.
