JK Products 48P Plastic Pinion Gear (3.17mm Bore) (31T)
Installed in a Kyosho Javelin re re. 17.5T HW motor and ESC, Kyosho upgrade spur gear.

The good: This gear works as advertised. Just by rolling the buggy on a flat surface, I could tell that rolling resistance was greatly reduced. Tested under power, the car was noticeably quicker.

The bad: The gear is strangely noisy. It may be an imperial and not metric pitch.

It also is very thin and I am not sure how long it will last, or whether it will cause my spur gear to develop weird wear patterns.

The baffling: Why did JK make the grub screw imperial and not metric?
