I think the way to solve this problem is to follow the National trend...just keep adding more classes. This way, 1 out of every 10 racers can be a National Champion.
Factory Masters sounds good.
While we're at it, let's add:
Rubber Factory Stock Brushless
Foam Novice Stock LiPo
Pneumatic Sportsman 19T Hamster-wheel
Mod TC3 Racers from Arkansas with Orange HPI Mustang bodies
But seriously, this reminds me of a quote from former Steelers LB Greg Lloyd.
"When that guy lines up across from me, he's got two choices. Either step up his game, or get his @ss kicked all day."
Anybody who wants to futher segregate the classes by moving the fast guys away from the rest (and make more classes) should read that quote.
This is competition...not kiddie-league soccer where even last place gets a trophy.
