There is a discussion on the mini micro forum about setting up 1/18th off road vehicles to race on-road courses (mainly carpet 1/10 tracks).

They claim that by adjusting the suspensions and using 1/10 scale foam tires that the 1/18th buggys and trucks will out corner regular 1/18th scale TC like the X-ray M18. I checked the dimensions and these 1/18th off road vehicles have the same length and wheelbase as 1/18 on road but they are as wide and have the same track as a 1/10 TC.

If indeed these mini trucks corner better because of they are twice as wide as the mini TC then I wonder what would happen if you took a standard 12 scale car(or a 1/10 pan car) and dramtically reduced its wheelbase down to something like 6 inchs.

Would you then have a even better cornering car?
Is the only reason RC cars try to maintian the basic dimensions of a car which is twice as long as it is wide because thats what the full size cars do?
