The Wasp is designed for the pilot who wants to continue to progress after leaving flight school or the recreational pilot looking for a safe reliable wing that uses the latest technology.
Several performance enhancing design features have been incorporated in the glider giving better stability and glider cleanliness.
The Wasp offers easy and responsive handling with good performance. At the safer end of the EN-B range, it is a rock solid glider that everyone will feel comfortable flying.
The Wasp profits from our latest evolution in glider design. The wings structure is clean and simple. The Cord Cut Billow technology really enhances stability and performance on this glider. Our Optimized Line Layout system yields a total line length of just 328m on the M size providing less drag and better flying.
We have used a Plastic Reinforced Leading Edge and Elliptic cell openings give the Wasp a clean nose and progressive, smooth collapse recovery.
Bruce Goldsmith’s gliders have been known for having great handling, the Wasp is no exception.


Cord Cut Billow technology has been developed to improve the form friction, glider stability and overall performance of our gliders. Two seams run cord-wise across the top panels of the leading edge, and these accommodate the panel ballooning that happens when the wing is inflated. Up to ten centimetres of excess material is created on the sides of an inflated flat panel bending over a wing profile. Normally this results in ripples on the seams, but our Cord Cut Billow technology means the bulge is absorbed into the panels, which reduces this rippling. This in turn improves the rib’s profile shape and stability.

Balanced Pitch Control The profile of the wing has been carefully selected to provide stabilizing glider reactions in turbulent air. When the wing rocks back or surges forward from turbulence or brake inputs, it will automatically and gently rotate back to the neutral position above the pilot.

Compared to the traditional Mylar leading edges a Reinforced Leading Edge with plastic spars makes the glider lighter, more durable, and reduces the creases on the seams Each plastic wire has its own pocket behind the top surface seam giving a more robust construction than inserting the plastic into the exterior seam. This also makes it easier to replace damaged plastic.

We have found that elliptical cell openings give better lower surface tension making for smoother inflation, and re-inflation after collapses.
