speed = rollout x RPM x 60 / FDR

You probably missed the 60, as RPM is per minute, whereas speed is per hour.

Rollout is already PI x Tire Diameter / FDR. You're including the FDR twice in the formula. Plus you need to divide by 1000000 to convert milimeter to kilometer.

No wonder the tire rollout is always at 197.8 !

The real tire rollout calculation includes FDR.

Rollout = PI x Tire Diameter / FDR

You use the rollout chart to determine your gear ratios and tire diameters accordingly for a certain track.

Thanks esham. Excellent work. However, I don't deserve the credit. This chart came from either the Kyosho Japanese web site or some other Japanese RC site. I just downloaded it and passed it along...

Really excellent work! Thank you..

I've just put together an excel spreadsheet with the calculations for Gear Ratios. It lets you enter your numbers tires dia/rpm and so on and calculates the result based on this wonderful chart.. PM me if you'd like a copy..

Cheers,

I did,.... T-1031 works better (highly noticeable when using OS engines), did a modified hand-made version of a T-1031 too for tight tracks,... rocket acceleration when mated w/ 12 TR(P)T,....

Thanks! True, the acceleration was super! Thought it was just only design for the 12TR, but was working very well w/ my TT12S1.

Buddy, if I recall correctly, your problem seems to be with the pipe you have. That should be the first thing you replace. If your pipe is not working well, the gear set will not help you either.
