ZX5 FS, with Orion 8.5, novak GTB

[dgrobe2112]

Guys, i did the search function, and couldnt find what i was lookin for. anyway, i thinl the lazer has a different final gear ratio than the B44.

How do you go about finding out the final drive? if i did it correctly, i come out to a 2.2 gear ratio on the Kyosho FS.

I am gonna run a 8.5 motor, what should i start at with the stock spur gear?
