I don't know if R/C Racing will ever get national coverage the likes of ESPN, however, I do believe that ROAR could help Race Directors with a little money to aid in advertising costs for the event. Having the race at a public venue would be much easier with on road classes, not too easy with Off-Roads.
Having said that, it would be interesting to see what kind of general media coverage the Off-Road Worlds will get next month...
