Ok , so that is one part of the regs.
But we did see very obvious differences in performance in the nearly original and close to 100% wood and the small wheels. So that could be one class.
And then we have those in between.
And then we have the "design houses", Red Dawg Engineering, Gormandy of Sea Lots, BSL out of Arima in California, and Crichlow aint reach as yet.
Interesting to look at the Video above and see the extremes with enclosed cocoons, nearly prostrate literally lying down on a seat with four wheels, the zero wind resistance layout on some.
That is where we can eventually reach with different classes.
And still no FIA Licence required!
