I've been seeing threads and talks on pinion gears...and i need some info please. If i had to find an 8 or 10 pinion gear would it lower the ratio as well? ...an can it be done on stock NB motor or preferably it should be done on higher powered motors?

And for the others gears...would finding gears with more teeth for lower ratio mean they would have to be bigger in size? ...or if i'm lucky i can find direct replacements from old toys. I'll be breaking up some of my old toys and i would like to know what i'm searching for.

Sorry if my questions might sound stupid to many but i'm really no expert on the matter.

thanks guys.

The pinion stock NEWBRIGHT owns ten tooth, install an eight tooth (YELLOW CRAWLER) would be very well ..
I keep my stock motor on YELLOW CRAWLER , but I installed a new gear in each diff ..

Change your motor for more efficient would be very well ..

I left the three stock diff in each gear, but I have to add one more (34x10) ..

I recommend the new gear system of MR FLAPDING 90/1 ..
