Can I ask what was the frame made out of ? And I've seen the plastic coating before isn't I shrink wrapped over the frame ? What's it called .
How did you stop it from snapping in the middle like most do ?
Sorry for the questions and if you'd rather email it's woody@apexloft.com
Thanks woody

Heat shrink Mylar
The wing has a full span aluminium Cylindrical spar with all bending moments and forces calculated using engineering science. You can look up specs for bending moments etc in engineering textbooks and materials suppliers.
The glider was all carefully calculated with wing LD ratios and wing loading and tip losses carefully calculated on paper before any building began.
You can easily get specs on wing sections online nowdays.

Um, Make sure your pilot is very fit and not fat and actually knows how to fly.
Practice flying the glider on a hill MANY times.
George flew the glider numerous times over land.
Understand ground effect.
Most of your flight will be in ground effect.
Get lots of airspeed by diving gently initially. Don't try to stay high or you will stall. Convert some of the initial height into airspeed and then you can cover a lot of distance. Try to get as much airspeed as possible on the ramp
