The arf vs kit debate probably won't go away like everyone says, and yes, they have gotten a lot better. I have built a couple that I really like, but the main problem you have with an ARF only builder is that he doesn't know what needs to be beefed up unless someone goes over it and shows him. You have the same problem with a new kit builder as well though. Anyone over powering a model should at least talk to people and find out what needs to be beefed up to make it stand up to the added power. Unfortunately, if they are new, they don't know to do that either. Its kind of a double edge sword. What do you do.

They do make some pretty nice ARFs though. (never thought I would hear myself say that.)
