Well, this years scout race is in the books. Thanks to the wealth of information available here, and tips from many of you, we were able to take first and second place in our pack. Our average times were 2.54 and 2.55 for the two cars on a 35 foot besttrack. I know that each track is different and you can’t make meaningful comparisons, but I did it anyway. The speed we were running today... 2.54 sec / 358 inches ( racing length of a 35 foot best ) = ~.007 sec per inch. Now to scale that up... .007 * 442 inches ( racing length on a 42 foot best ) = 3.13 seconds. Looks like I’ve got a lot of work to do...
