Hitec D954SW High Torque Steel Gear Servo (High Voltage)
Worked well for 1-1/2 years through several pretty severe tumbles on my Axial Capra. Broke a tooth on a very minor tumble, and 10 mins later the whole thing was stripped. Called Hitec, gears aren't covered under their two-year warranty, and that's not mentioned in the section for servo warranty, it's covered later under the general limitations of the warranty, which I didn't read until after I was badgering them about the warranty. However, they honored the first paragraph after I was a squeaky wheel by sending me a new gear set.

All that said, it's not quite perfect, but it's quite good, and after all is said and done, I'd buy another.
