How about building a plane that uses the magnus effect, like a Flettner airplane?
After doing a search on your youtube channel and the forums, I don't see where Flite Test has done that yet...
Hey guys! Love your show and your work. You guys are the Mythbusters of flying stuff! I would love to see your take on the FanWing (fanwing.com) concept. It uses the Magnus Effect for propulsion and lift. No props or jets! Anyway you guys are great. Thanks for all you do!
