Perhaps even a little more ingenious than old Mac. Talk about working with what you have on hand. This from the site: "20 year old Chinese farmer Wu Zhongyuan built himself a helicopter using only — according to the man — what he remembers of middle school physics lessons and "relevant knowledge [found while] surfing the Internet via my mobile phone."
Well, sure looks like things worked out. His single-seater conveyance has blades made from the wood of an Elm tree, a frame reinforced with steel pipes and uses an engine from a motorcycle — all for around $1,600. Wu claims the 'copter can get him as high as 2,600 feet, though it seems he's grounded for the time being as the Chinese government has forbid him to fly because of safety reasons." via BoingBoing
