I used to have a stadium blitzer too. That was my first decent RC and I remember it being pretty fast. I used to be able to hit the double jump down my local bmx track, jump the first hump and land on the downhill of the second. My Revo is a monster in comparison, and at least twice as fast, but I remember the blitzer being pretty good.
I think if you want another hobby, it could well be fun to rebuild. If you want to get back into RC properly though, get a nitro truck like the Losi, T-Maxx, HPI Savage or Revo. Much more time needed, but much more rewarding. I started the hobby thinking it'd be good fun as 'something else' to do, and now it's my main hobby. Really addictive and good fun.
