Ornithopter

It's a bird, It's a plane, No! It's...well...um both?!
An ornithoter is a flying machine that acquires lift by flapping a pair of wings. It converts rotational energy into linear (flapping) movement with a crankshaft at the front. Way back when, smart people, like da Vinci, believed this was the easiest way to give man powered flight. We know that this assumption was clearly wrong. Experiment launching this device at different angles ,relative to the wind, to get the best flight possible. (The wind may also assist in some crazy acrobatics!) All you need to do now is print/assemble your Ornithopter and get ready to take to the skies! https://youtu.be/W-_lnUAN0RA
