Hey, I just purchased a Tamiya TA04S that has basically been hopped up to R status... anyways, I'm looking to get into racing indoor on-road, but I'm a total RC newb when it comes to advanced car building like this. I need to get some pinion gears, and maybe a couple spurs depending on what I need.
Basically, what I'm looking to know is are there standards in racing that everyone runs the same gear ratio?
if so, what is fairly typical for indoor road courses?
I know the internal transmission ratio of the TA04 is 2.123, and the spurs I currently have are 48 pitch 90T, 83T, and 64 pitch 96T, and 128T. I only have a 48 pitch 19 tooth pinion, and need to get some others to make the final drive I want.
I ordered a 39 tooth pinion to go with my 128 that will give my car a final drive ratio of 7:1 according to the calculation (spur/pinion x internal ratio).
That may not be good for racing though, I really don't know.
What ratio should I have for a road course, and what may be some good combinations to get it. Probably should use 64 pitch?
I appreciate any info to help me get this bad boy going
