AutoGyro Ring Glider

There are a couple of problems with most of the 3D printed flying rings: Firstly, it's difficult to get the right mass distribution with 3D printed plastic. Secondly, they are damnedably difficult to throw with the proper spin, and liable to tear your rotator cuff.This is a rubber band launched version that derives its spin from the angled fins that connect the ring to the central “stick”. The stick itself solves the mass distribution problem allowing you to have a uniformly thin ring, yet still get enough mass out front to locate the center of gravity at the center of lift. And minimal cross sectional area minimizes drag.Launching with a rubber band, however, presents it's own challenges as the lower part of the circular wing wants to hit the launching stick. To solve this, I've used an articulated stick where the business end springs forward out of the way once the rubber band launch tension is released.Note: I've completely updated the launcher so that it releases the glider more re
