Hi all,
I run a 1/10 touring car with 64pitch gearing. My internal ratio is 1.85.

If for example I ran:
a 100t spur and 44t pinion I would have a final drive ratio of 4.205
or
a 116t spur and 51t pinion I would have a final drive ratio of 4.208

(Putting aside the very minute difference in FDR) Obviously running option 2 above I have more teeth in my gearing over all.

Theoretically the strain on the motor would be the same.. ? I don't know

My questions are,

- would there be any difference to the drive of the car? (acceleration, speed, etc)

- and are there any advantages or disadvantages of each situation?

Many thanks for any responses!
