About this 3D model

A fun little flying model helicopter. As simple as it gets! Two propellers held apart by a body and a paper clip, and powered by a rubber band. Quick to print and build and really easy to get it flying. I made the propeller design as an upright flat so that it prints quickly without needing support. The pitch on the propellers is added after printing by heating and bending. http://youtu.be/ShZxD3JiJlY
