Oh, just noticed this posting.
The track in this thread fits on a 8' x 12' table.
The one used in the Sprite Proxy is Luf's Targa Burnaby.
I believe the average running length is around 80 - 90 feet and you would be able to fit a similar configuration in your available area. It's just a terrific track to run with the elevation changes and new wide sweeping back corner. I'll take more exact measurements before this Friday's races at Luf's.
He's contemplating some major revisions so stay tuned!
