Where have all the ALL balsa kits gone? I am new to the board so forgive me please. When I was younger like 30 years ago my father always made his planes from a kit of balsa. I am trying to get my son interested and all I can find are pre-maid kits of various materials OTHER than balsa. What fun is that? Are there any manufacturers out there that still make all balsa R/C kits and if so PLEASE point them out to me. Thanks.
