2011 Sport Race Rules
Be aware that continuing this year we are going to be VERY stringent on following the ruleset, and Keith Morgan will be our Racing Director in charge of processing models and engines. His word will be final and no arguments will be tolerated. I would like to personally thank Keith for his generous offer to volunteer in this most necessary role, that will hopefully save racing, such as it is now, and perhaps help it flourish with increased participation in the future.
