I think that at a race such as the IIC, Cleveland, or even a Nationals the "stock" class should be for non sponsored racers, the 19T class should be kinda like a pro stock class with 30-60% sponsored drivers and any club racer that is up to the challenge and the same with mod which would include Factory drivers, 30-60% sponsored drivers and the ballsie club racer. Like people have said if your novice you probably wont be at a national or any such caliber race but there are racers that never been to such races that would have a lot more fun and a more enjoyable experience if they werent moving over for 5 fast sponsored drivers 10 times in 1 heat, r/c is very competitive and people get discouraged easily when they feel like a moving opsticle, but they also want the chance to race at a prestigious event and get to watch there favorite drivers battle without being in there way.
