TT01 Question

Just got one and I have a Firebolt motor with an 18T pinion on it and it doesn't seem to match up with my spur gear. What size pinion do i need to use?

Try 19T pinion/61T spur.

Just counted my spur and it's a 61 so I'll have to order a 19T pinion unless anyone else wants to chime in

Just be sure you get a Tamiya metric pitch pinion.

The American 48P gears are a slightly different pitch from Tamiya 48P gears so the two will not mesh correctly.

These Tamiya pinion sets are available:

50355 18T, 19T AV Pinion Gear Set
50356 20T, 21T AV Pinion Gear Set
50357 22T, 23T AV Pinion Gear Set

These are 48 pitch metric pinions. The number of teeth is stamped on the pinion so they can be identified which is which, and are made of aluminum.
