Description:

The Duck has been designed primarily for aerial combat and aerobatic mucking about on the slope. It's extremely agile, boasts remarkable inverted performance and corners like it's bouncing off a wall.

The Duck is very flier-friendly. While tip-stalling is a problem that plagues many other swept flying wings on the market, the Duck has been designed to overcome this tendency and behaves itself admirably when setup as per our recommendations. Recovery from stalls or mid-air collisions is also very quick, allowing flight control to be regained before contact with the ground in most situations.

The relatively light wingloading of the Duck combined with its carefully calculated aerodynamic design allows it to be slowed down to a hover without stalling and accurately positioned to pounce down on its target. Hand-catches and spot landings are made much easier and its lift characteristics also enable the Duck to comfortably fly in conditions that would be considered a little marginal for the Skua and Booby.

Even though speed wasn't the highest of design priorities for the Duck, it delivered a pleasant surprise during testing. The Duck is indeed very quick and capable of out-running any other wing in its class. Its broad speed range combined with its hard-hitting manoeuvrability make it a fearsome competitor in any combat session.

Durability is top-notch. The Duck is constructed entirely out of expanded polypropylene (EPP) foam and reinforced with a carbon fibre ribbon spar system that combines super stiff in-flight characteristics with the flexibility required to absorb the forces of impact without damage. EPP foam will not dent, crease or crack like regular polystyrene foam and, when combined with fibreglass reinforced strapping tape for added tensile strength, will immediately spring back to shape ready for action even after the meanest abuse.

While not designed specifically for beginners, the Duck can still very successfully be used for learning the basics of slope flying as long as care is taken during its construction and the CG (balance) and control throws are setup appropriately as per the included instructions. The Duck can handle the inevitable beginner bashes with ease and, once skills improve, the extra performance compared to a more docile traditional trainer model will likely be appreciated by most flyers.

Whether you're an avid slope combat competitor, a newbie to sloping, or someone who simply appreciates flight characteristics that enable you to perform your slope stunts like a seasoned pro, one wing holds its head above the pack. Duck!
