And the one's that can fudge the rules without getting caught are the winners in any racing.Racing plane, racing rules. http://www.sonerai.net/repository/formula_v_rules.pdf
Plane must weigh a minimum of 450 lb. Pilot must weigh at least 170 or sit on some ballast. Remember racing rules are restrictive to try and make a fair contest. What you can do for racing is completely different than sport flyer. I noticed that the speeds are intended to stay below 190. Weight may be the enemy, but in racing its not a free for all. You have to play by rules.
When NHRA drag racing went to Bracket Racing, I quit. I don't like socialized racing.
