The awesome thing about hobby grade r/c is that if you do break them, and you will eventually, they can be easily repaired. Most major manufacturers even offer detailed .PDF files online of exactly where each part goes, the part number for it, and some even include the msrp on the part so you can get a ballpark estimate of repairs. You either like to tinker or you don't, and if you don't then radio controlled vehicles might not be a long-lived hobby for you.
I hate to break stuff, but at the same time it's just an excuse to buy a better part to replace it with and make it better than new. Plus it gives you something to do on the rainy days. I'ts really a hobby that includes many other hobbies.
You can paint, customize, repair, troubleshoot, enjoy, spend 3-5 hours at work on this website talking about the hobby, etc...lots of different things all wrapped up into one great hobby.
