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?

I have ran the 31t pinion for months in both 21.5 and 17.5 with a slipper eliminator on carpet for 2wd racing. I have zero issues and this pinion literally shaved off .2 seconds of my overall 12ish second lap times. It shows 0 wear and tear just looks dirty. No gear cover either. I will be ordering more in various sizes when I move to mod.

The set screw is not 1.5mm like it should be. None of my standard RC tools work with it.

These gears work great if you run on carpet or use a transmission gear cover...if you run in dirt ouside they may pick up small particles and chip the teeth.
