RE: Arf's and builders ?
I build kits and assemble ARFs. I think the ARF has opened up the hobby to a different kind of participant. Whether it's a time issue or the lack of tools/confidence to build a kit to completion and see it fly. Either way it is good for the hobby. I myself build kits and assemble ARFs. I hope to see the hobby build more ARC's. Ie.. TF giant P-51. If I could purchase more large aircraft built but not covered, I would most likely stop building altogether. This would give me the ability to have a new airplane with minimal build time, yet be able to cover and detail as I like.
Just my two cents worth.
