A 10th scale car doing 10mph does not equate to a full size car doing 100mph. Simply multiplying the speed by the scale does not work.

An example from the real world:-
A whippet can reach speeds of 35 mph and is very close to a half scale grey hound. Yet you do not see a grey hound running at 70mph. More like 40mph.
Similarly, the top speed of a humming bird is equal to that of a goose.

The scale speed calculation which provides the most realistic performance where the scale model performs in a realistic manner:-
The speed is found by multiplying the 'real' speed by one over the square root of the scale.

A 10th scale model doing 25mph equates to a full scale speed of about 75mph.

maybe 1000th even?

(thats weird.. i think my spell check messed with the 'th')
