Videos of Phil Barnes launching early versions of the DHL Logic. Aileron and Poly. They're not the best quality as the encoder kept dropping frames but you can get an Idea of how he launches a DHLG.

Bert Magin taking a stock Xterminator Fuse and Obsession wing and Side arm launching it. No reinforcement eventually took it's toll. Says Bert,  "I can throw just as high as my Javelin launch with less effort."

Phil Barnes new beautiful DHL prototype Kevlar and Carbon wings. In bottom picture, right wing will be an aileron wing.  Kevlar is laid on a bias with carbon cloth in-between carbon cap and leading edge for an exceptionally strong wing and still very light at 4 ounces. Pic files are a little large. PhilsNewWings_Jpg_1.JPG (65743 bytes)
