Dave Klein is a serious glider flyer and he just happens to be a engineer working with composites structures on UAV's. I interviewed Dave and we chat about composite structures and how they apply to the planes we all fly. Lots of discussion on HLG/F3K/F3B technology and other subjects, techy, but no math needed to understand this stuff.
