We are excited to announce our updated schedule and rules for the 2027 Season at Checkered Flag R/C Raceway. All races will run one qualifying round and the mains. We want to thank all of you for your support over the years and are looking forward to celebrating Season 24. Anyone interested in sponsoring a class or the track please contact us with any questions.
2027 Class Rules
• All classes are required to display proportional sized numbers on each door, and the roof/wing of the vehicle. This not only increases racing realism, but also enhances the race director’s ability to make sure each car is counting correctly, and provide accurate running order announcements during the race.* It is each Racers responsibility to supply their own 2 wire MyLaps Transponder. Thank you for your cooperation in making the racing experience at Checkered Flag Raceway the best it can possibly be!
