Could I install this on my arrma mojave 4s?

Damian Doran / 2nd November 2025

That would be a little small - this is the standard Mojave 4s pinion: ARA310999

Good morning, I'm after a couple of steel pinions for my Tamiya Clodbuster. It's 32p 13t, the only ones I can seem to find on your site are the Arma ones. https://wheelspinmodels.co.uk/i/303807/ Would these be compatible? I'm assuming so as it's just the pitch and tooth count which matters? Thanks, Dave.

Dave Jones / 15th March 2021

Yep - these should work - they sound the right pitch and tooth count. Just bear in mind these fit a 5mm motor shaft (yours is likely 3.2mm?)
