IMPORTANT: “Spirit of Competition”

If it is not in the rules and does not encompass the spirit of controlled RC racing with realistic scale looking cars consider it illegal. The intent is to provide a level playing field and put the emphasis on “Fun friendly competition” Regarding TECH - we will be running on the honor system with each driver responsible for ensuring that their car is legal under the “RCO Basic Class Specification” with top three finishers in each main must be willing to submit their RC racer for a quick inspection should there be a protest from the run group. An inspection / self tech table will be provided for all participants to use at any time with the basic regulations posted for quick reference. Minimum Ride Heights are required to protect the running surface – the carpet is expensive and we want to keep it in good order for many years to come. Always use common sense and safety precautions when charging battery packs and please respect the facility we are fortunate to be permitted to use.

The focus of the OORRCR is to provide a fun place to enjoy the scale on road racing hobby! :)
