Sorry, I have been tied up today so I am replying late. My comment that I can't build an airframe for the price I can buy the same ARF has been pretty well answered with other people's posts, but just as an example: To cut out from balsa, plywood, and spruce the parts for a 1/3 scale aerobatic scale model, I would guess the bill for wood alone would be $300.00 or more. Then add another $200 for covering. Then consider a fiberglass cowl, hardware package, dural landing gear and so on. I would spend close to $750 to $800 to build the same airframe I can buy in ARF form for $600.00. Back in the "old days" when no one knew what an ARF was, us "geezers" built because there was no alternative to it.
