It must be, Kieren. The control surfaces, and tail structures are no where near scale. That implies it is intended to fly.
Royal used to make a 1/4 scale version of the 109F4 (I think it was). It had a pretty hefty price for a balsa kit, but Royal kits were the best then and probably still are.
Recently, the only Royal 1/4 scale kits I have seen are the F4U1D and the Christen Eagle II.
