Scott I copy the rules down here, I am going to ask the guys in the dc region if they have anything. As Lynn said dave is been researching about FJ, and he is going to be the fj safety steward for next year, he also mentioned that he is willing to let other kids to use his kart.


Rules

At any Solo event where Formula Junior (FJ) uses the same course
layout as all other classes: For any heat in which FJ is in competition,
no car in the grid may be in motion when any FJ kart is moving under
its own power. From the start of FJ competition, when the fi rst driver
in the class leaves the grid for the start line, until the last driver has
returned his kart to the FJ grid, this rule shall apply.

The Formula Junior (FJ) program is provided that allows regions to permit
minors less than 18 years of age to compete in Solo events in nonshifter-
based racing karts. The purpose of this program is to serve as a
tool for membership recruitment and retention by providing competition
opportunities for the entire family.
