Well, I can look through the ROAR rule book, and I don't really see too many things that are "out of touch."
When this "rocket ship" body thing started, the manufacturers were doing it knowing full well that ROAR or IFMAR might put their foot down. The rule book HAS ALWAYS SAID the bodies will resemble the bodies of full scale vehicles for the class being raced. I'm sorry, but real off road buggies have a net over the window, and none of them look like off shore racing boats...
