I have just purchased an early production shaft drive tourer with no details as yet of the internal ratio.
Also, I will be trying this car out with both a 10.5t brushless and a 17.5t brushless, so what are the idea ratios as a starting point for both these winds? (I have run a 17.5t in another car at about 3.6:1 which seemed about right).
Thanks in advance,
spur/pinion X internal gear ratio.
how large is the track you're running on. i was at a 3.5fdr for my 17.5 but tried a 4.0fdr and i was just as fast but the motor was cooler and i had more low end speed.
for the 10.5 i believe it/s 5.6fdr and up, just guessing.
