Its a good idea, but maybe too little too late. Kids have that now through sim racing games. And varous motorsports do use games/sims to scout talent. A case could still be made for RC where the hands on and wrenching aspect comes in. But for the actual racing, it'd be hard to compete with 1:1 sims, at least for people aspiring to become real racing drivers.

For stepping outside of the hobby. Traxxas proved it can be done. The difference is, they did it to promote theirbrand, not necessarily racing. But they do get people into the hobby. If AE or Losi started doing what traxxas did, that may get more people into model racing.
