RE: Will increasing the thickness of a biplane wing decrease the stall speed, or just add useless dr
If you want a bipe that is excellent in aerobatics yet will have a good glide ratio then the Goldberg Bucker Jungman is the ticket. Unfortunately it is out of production. I have sent emails suggesting they bring it back but to no avail. Anyone who has flown one knows what I am talking about. Just an fyi.
