As Poboy said, welcome to the asylum, though they don't quite let the inmates run it (thank god)
I come from drag racing and used to be into RC cars. I'm really having a great time with these little motors. You'll be able to feed the need, you can soup these freaking things to the moon. I had a my minibike with a 5.5 honda on nitromethane last year, and although it kept my hands and knees skinned up, and ruined my rear fender it was a huge amount of fun. 50mph on a minibike is like 130 in a drag car.
