2009 August LIFT
Thanks for sending in your lifts!
Tony Prentice sent cool link for Worthing Birdman videos, stills, and news: HERE. "The big flyers of the day were Toby Quantrill at 75m, Roy Freeman at 82.03m and the longest flight was by Steve Elkins at 99.87m, just 13cm off the 100 metre goal."
SPEEDLAB 16 m2 speedglider plans
The SPEEDLAB is a reduced version of the gnuEASY, with some variations:
- Removal of the profile number 12 (even simpler)
- Removal of all mylar reinforcements
- Leading edge improved with fiberglass rods 2 mm (rigifoil)
- Area reduced to 16 m2, then, very little consumption of ripstop tissue (46 ml) and dyneema lines (185 m).
- Inexpensive, and easy to build...
best regards,

Enter the brainstorming fun session on
"beginning and ending PG flying
at 1000 m above ground level (AGL)" (This is very different from common practice.)

"Most model motors in the size ranges of interest in this presentation are brushless, and are
either inrunners or outrunners"
