Wow JW, talk about a bad attitude. If you beat up your cars then of course you'll have to fix 'em. That's part of the hobby. Don't take it out on other people, especially those just getting interested in it :think:
I love r/c, I've had a team associated RC10 truck for a couple years now. Great little hobby, especially if you find a local track or make one yourself. Just be sure to take care of it and you'll never have any big problems with it! Mainly just be sure to clean it off often. I rinse the dirt off mine and then use a commercial compressed-liquid cleaner bottle to shoot into the small spots, which pulls the dirt out of places I otherwise couldn't get to.
Those tiny little engines are air cooled and if you don't clean 'em they'll get covered in mud, causing them to overheat pretty easily. That's the only thing I'd warn you to be sure to do regularly.
You should expect to spend some time taking care of your r/c, though. Don't go out and buy one thinking it'll be something you can just hose off and put away. You WILL have to do some small maintenance. But it's not a big deal, and if anything, that should be part of the reason you want to get into it in the first place.
The biggest single "thing" I've had to do to my buggy in several years of tooling around with it was replacing the steering rod connectors. One day I was driving it up and down the street and I let it get too far away, lost the radio signal, and the car veered into a curb at an angle. It snapped the rods where they meet the wheel. Made a quick trip down to the local hobby shop (where, btw, they should have replacements for ANY part of the car, so no need to worry about anything like that), got the new connectors, came home, unscrewed the old ones, put on the new ones, and the buggy was back on the road in twenty minutes! The engine had barely cooled before I started it back up again.
So yea.. I say go for it! And by all means let us know what you get.
