For a while I had a nice little RC-10 that was semi-"tricked out". I got my it (+ remote + many spare parts + charger + extra battery pack) from a friend that raced them. It was about $350 worth of hardware that he let me have for about $125.

And because he raced them he had his car modded quite a bit. He had all the excess weight trimmed off, and the suspension was lowered and stiffened, low profile super-soft tires.
That was fun for while, but luckily the spare parts included another set of tires (knobby) and larger, softer shocks for transition back into a Baja buggy.
But it got stolen!
I'll never forget one night when driving with a friend I noticed there was no one on the road we were going down. So I stopped the truck and told him to put the RC-10 out in front of us then get back in the truck and control it while I drove behind it. I just wanted to see how fast it was.
Well, nothing too exciting about this story (I didn't run over my RC-10 or anything like that

) but I was pretty impressed that the little thing could do a little over 30 mph.
