thanks guys...
that sounds great. i guess i will try the Novak motor.
and i am sure to be faster than the other car ...
your ratio should be about 7,8:1 .. more or less the same as 64/17...
the tires are great, but hadn't had the chance to try the tamiya S-Grips right now. (for comparing the differences) i hope to have the time for testing this week
they should also be faster , due to the bigger diameter.
