RE: KOSMO .60 BY MANTUA MODELS.
Yes I have a NIB kit that I got off a friend. It's a 1974 italian champs winning design by Benito Bertolani. Never heard of him but the plane is very nice. It has some very nice prefabricated wooden parts and apart from the straight trailing edge it's not unlike the Blue Angel. Mine includes all hardware (for fixed trike gear) and even a hardwood/metal universal wing jig.
