2 PCS MG995 Servo Motor Control Angle 180° Metal Gear Waterproof Digital High Speed Torque for RC Airplane Helicopter Mechanical Arm Car

The gears are plastic and not metal as they claiming

These servos seem to get a lot of interference and are very jittery, they went into the bin. No use at all!

They have some strengh to them. However, i installed a set of these on my nitro rc car and the throttle one keeps stalling/locking on to full throttle after around 10 minutes of use. This has caused quite considerable damage to my car with it running away and crashing. Also, they turn quiet fast but the response time is aweful. I can go from full brakes to full throttle on my controller and the servo takes around half a second to respond. I know its the servos as the old ones respond fine. Its same with the one i put on steering too. You have to think a second ahead before putting input into controller. Its a small delay but big enough to be able to lose control. Ill be sending these back.

No matter what pin combinations I use on my 3D printers control board, I get a short to ground with both of the units in this two pack.This only occurs when the servo is actuated and I can only deduce that there is a fault electrical assembly or design as I do not have this issue with other servos.

Not that happy with these servos they sound real gritty as if they don't mesh together properly.
