I want to see something like an r/c decathlon. One driver has to take his one vehicle and compete with it in an oval, on-road, off-road, rally, drift, drag, etc... race. The car would have to stay basically the same during the entire competition. Maybe allow different tires or shocks depending on the type of race. Maybe a different body as well.
Let's see how good the best r/c racer's are when they have to do it all in one event.
I'm currently racing VTA. Check here for rules/info: http://www.usvintagetransam.com/
