Elastic Launched Glider

General
Elastic Launch Glider is a 2012 Division C trial event at the National Tournament.

The 2012 rules may be found here.

Basics
This event is a building event consisting of two parts: a glider made to be launched by the pulling and releasing of a rubber loop, which can be constructed based on plans of the competitor, or from a kit, and a flight log similar to that of other aviation events.

Construction
The glider is allowed to be built from any plan, published, student-devised, or otherwise. It can be built from wood, carbon fiber, glue, paper, and plastic flim only, with any non-metal malleable substance able to be used as ballast. In competition, the glider is launched with the elastic loop, fly upwards balistically until it reaches the ceiling (it is an indoor-only event), and transition into a circular glide which maximizes the time taken to descend to the floor; thus, the glider has to be built to be able to do this. Firstly, it has to be able to withstand the initial jolt of the launch, which means the contruction, particularly of the wings, is significantly different from that of the other aviation events. The glider as a whole has to be much more durable but just as aerodynamic as the wings/rotors of the devices of Helicopter/Wright Stuff.
