Injora gear pitch?

[Tucky]

I have looked all over but can’t find the pitch of spur gear in the injora 370 transmission. I need to order up a pinion that will match up.
Anybody know what it is? Can I measure it with a thread pitch gauge or are they two different things?

Thanks

I didn't see anything regarding the pinion mentioned on the Injora listing for the 370 transmission, but .4mod is mentioned at the links below.

Cool, I’m putting a quikrun mini 16 in my TRX4M and I’ve probably already have that pinion hanging around somewhere, I’ll drill it out to 2.5mm and give it a shot.
