What pitch do I have???

Hi Guys,

I bought a Duratrax Vendetta, and I received a Align 430L brushless motor with it, but the problem is that the shaft from the motor is 3.16mm and the standard pinion from the Vendetta is like 2mm or something. So I searched for a 3.2mm pinion, and I saw one on this site, and the pitch of it is 32. But I don't know what pitch the standard pinion has, and I can't find something on the site.

So how can I measure the pitch of my pinion?

Thanks!
