Cul de canard Cul de canard Cul de canard (CDC) (French for "duck bottom") are the feathers from the back of a duck directly around the preen gland (uropygial gland); they are very buoyant due to preen oil produced by the preen gland. They are used when tying dry flies for fly fishing. They owe their buoyancy to their proximity to the ducks preen gland which secretes an oil distributed by the duck as a cleaning and waterproofing measure. It is unnecessary for the angler to add additional oil by way of floatant. Flies incorporating CDC are easy to dress requiring no floatant
Aviafiber Canard 2FL Aviafiber Canard 2FL The Aviafiber Canard 2FL was a one-person recreational aircraft of highly unusual design, designed and built in Switzerland during the late 1970s and early 1980s. Variously described as a rigid-wing hang-glider or as a foot-launched sailplane, the Canard 2FL was the brainchild of Swiss aerodynamicist Hans Farner. Of fibreglass construction, it consisted of a tiny fuselage, just big enough to accommodate the pilot in a prone position, provided with doors in the bottom through which the pilot's legs could extend for takeoff and landing. A large canard was fitted at the nose (as the name suggests), and
