If this photo had been taken in England (which it clearly wasn't - too much sun!) I'd have said the builder was Dave "Tubby" Day,whose website is still viewable somewhere. I saw him fly the shiniest (Monokote) red Nobler I've ever seen - on practice flights, just for fun, he'd do two or three consecutive square eights so incredibly small and tight you could hardly believe what you were seeing. That must have been fifty years ago...
