New gears for OpenRC F1 car.

New gears to give more ratios to choose from for the F1 OpenRC car from Barspin. The 9t pinion and 46t spur gives a top speed only 56% that of the stock gears. Apply a tiny amount of grease to the pinion if it melts. Mine work great.

The parts contain:
A 46t spur, bigger than the 40t stock spur.
9t, 10t, 11t, 12t and 13t pinions.
