believe it or not that little damn shell do so little to attract new comers
the drivers' attitude arround the pit, the drivers' ability to drive, the tracks' location and condition, fellow racers' manner when driving, the paintjob on the shells, all contribute to make this hobby attractive.
plenty of new comers come up and talk to me when i play at the track and they are attracted by the speed and atmosphere, and of course our friendly racers around the pit.
at the speed of today's rc cars what can you see except of the main colors on the bodies when the cars are moving, and if you look for scale appearence on the bench then as someone mentioned you might as well look for 1/24 models
you can talk to your local tracks organizers to see if they are interested in creating a new class with tamiya and kyosho bodies only, and screw ROAR and IFMAR, who cares about them when you do local races and only racing the local people, the people can decide the rules
another thing is scale bodies are expensive here in north america, specially in canada, the tamiya distrubitor is selling the bodies around 3 times more expensive than the price of the same shell in asia area, that deters new entries if what they are looking for is scale
