This superlight (84 pound) pedal-powered aircraft is built using techniques common to RC aircraft builders. It represents one of several projects taking to Chinese skies in a Do-It-Yourself movement.
A Chinese DIYer named Mao Yiqing has designed and built the human-powered aircraft, which he calls Mozi (after the 5th century inventor of the kite), using his skills running Oxai, a company that builds RC planes. Mozi was built using many of the same techniques and materials — balsa wood, styrofoam and carbon fiber — as his model planes.

Yiqing was preparing his plane, which weighs 84 pounds and has a wingspan of 81 feet, for a 4-mile flight across Dianshan Lake near Shanghai.
