Personally I think Dion is on the right track. When "surfing" this site, I'm looking to view ideas and/or issues of a certain aircraft. There is a "Warbirds" option, but it's mixed with Kits and Arfs.
I build/ fly both kits and ARF's by the way.
If I'm looking for ideas, say on my next project - Hangar 9 Hellcat (when will they release that baby anyway!!!!), I have to look/post in both ARF/RTF and Warbirds. And for my current project, a Top Flite Bearcat, I look in Kit building and Warbirds.
I think it make since to split the categories as I've outlined above.
Change it/ don't change it, I still enjoy this site and appreciate all the sharing of information and ideas.

I forgot, there is also the "Scale Aircraft" forum.

So where do I post questions on the Hangar 9 Hellcat? Warbirds and warplanes? Scale aircraft? (Yes I would call it scale) or ARF/RTF?
What if I crashed it while Sport Flying? Would those questions go in Kit building or Sport Flying? [sm=bananahead.gif]
