Kyosho Big Brute pinion
#1

OK, So I bought a Big Brute the other week. (I had one as my 1st hobby RC) However, the pinion is knackered, and I have no idea what gear pitch Kyosho used on these old Car Crusher series kits. Does anyone have a clue? I hear arguments between 0.8mod and 32dp, but I need fact.
So if anyone knows, could you let me know please, that'd be great. Thanks in advance

Not sure what pitch the big brute pinion is but my old turbo optima has a 32 pitch pinion. There's a few on e bay.

I contacted Kyosho America and asked them but haven't heard back yet. Maybe they will answer my question. We'll see..

Maybe we'll have an answer for him then. Hope he comes back and checks. :-)

So, Kyosho never got back to me. Anyway, looking at the manual, that's defenitly a 32 pitch pinion gear.

Hi guys
Many thanks for helping me out. Well appreciated. I did some digging of my own and after much ado, I found the pitch is officially, 0.8 mod, but 32dp is indeed a suitable replacement.
We all came to the same conclusion. Thanks go out again to you guys for chipping in.

Tamiyas have always been 0.6 module. I gather it's a metric pitch, and being a Japanese firm, that sounds plausible. While 32, 48 and 64dp are imperial maybe, being used by the likes of Associated, Losi etc back in the day, and both hailing from the US. Makes sense to me.
