Jerermy Clarkson from the 'Top Gear' TV show has a mid sized plane sitting in his front yard. Its damn cool, but maybe a little bigger than your plans. Im sure theres one like your thinking, just waiting to find a new home. If not, it wouldnt be to hard to build one. Id buy a balsa wood model kit, then scale up the plans. Once built and painted, it would easily appear to be real.
