HS-5055MG Metal Gear Micro Servo Motor

That servo broke after a few hours of usage. After inspecting inside to understand what transpired, it looks like the metal gears advertisement concerns only some of the gears. The one immediately next to the motor gear is made of cheap thin white plastic and lost a third of its teeth in one go... Very disappointed...

I used these servos in my micro robot arms https://www.youtube.com/watch?v=7KrpF0ggmlg and they work much better than the cheaper version of this servo (HS-55). Provide good torque, smooth and much more robust than HS-55. For the lot which I purchased I did not have any problems with any of the servos.

Though more on the $$$ side I still did not find a better servo in this size. I would reccomend the digital servo programmer if you need to adjust parameters.

I bought this servo as a replacement steering servo for my Torro 1/16 scale M16 Halftrack. It came with a selection of control arms and was pretty much a drop in. I had to enlarge the hole in the control arm to fit the M16 and re program it for direction but Robotshop was very helpful and it works like a charm.
