Dang man I bet plane tickets all over the U.S., Japan, Europe etc. get really expensive.
I find it hard to believe that one of the most popular forms of real racing doesn't have a large following...
Since when does a national event constitute a class being popular? Every company that I am aware of makes at least one drift car, same goes for rally cars.
Nope I mean rally, ya know that class that has been going since the 1930's all over the world. Kyosho, Thunder Tiger, Traxxas, HPI, Tamiya, Losi, Associated, Atomik, Rally Legends, Exceed, etc. all make or have made rally cars in the last few years. And besides a couple of these companies most of them make several models of the cars, same with drifters.
Its not a massive class, but does have a growing following. It has always had a really good following over in Europe, but real Rally is still trying to gain momentum in the U.S.
Again National events and guys at your local track don't constitute a class being popular. Most of RC is comprised of bashers and guys that go out by themselves to have fun. I am willing to bet most of those "bashers" don't own stadium trucks. RC is about personal appeal and to many the scale aspect is becoming ever popular.
Race classes die over the years, its a fact, its doesn't happen because of looks, it happens because of politics and things being blown out of proportion. But most guys race because of a competitive drive, many will say they go to hang out with their friends, but at the very least the first event they came too they came to compete.
