Top speed calculator

i was bored today, and made a top speed calculator for RC cars. it could work for a greenpower car, so have a look :-)
download version 1.2, its the only one that works. the others are for reference.

internal gear ratio should be set to 1, pinion is the gear on the motor, and spur the one on the axle, and the motor RPM is 2000.
Enjoy finding all the bugs! -
314mph for meee

Here are two that I've found useful for those who can't get Joe's to do the business.
For the first, you need to set RPM to 2000 select a wheel size in inches (measure it rather than read it on the tyre) and it will give you the final ratio based on your target speed.

Use this one if you have a lay shaft (intermediary)

Enter rider cadence as 2000 rpm.
