Deltaplane Deltaplane : Space
Français Envoyer traduction
English Easiest hang glider to land that I have ever flown. Period.

Deltaplane Deltaplane : Eclipse
Français Envoyer traduction
English This glider was designed by Jean-Michel Bernasconi and Bob England, and was manufactured not by Airwave but by Pacific Windcraft in Salinas, California. It was produced from 1985 to 1988. It is possible that some sails were sold to Airwave and fitted to locally-produced airframes. (This was certainly done with the Eclipse's successor, the Mark IV, which was called the "Calypso" in Europe. By that time, Pacific Windcraft entered into partnership with Airwave and became Pacific Airwave.)
The Eclipse was, without a doubt, the lightest-handling glider I have ever flown. It could easily be steered with one hand in steady winds! It was also the hardest glider to stall that I have ever flown. Even when it was close enough to stall speed to "mush," I could still get a controlled turn out of it when I needed to, without a tip stalling. I test-flew dozens of them when I worked for PW, and found them lacking only in glide at speed.

Deltaplane Deltaplane : Demon
Français Envoyer traduction
English For the record, the Demon was also made under license from Hiway by Flight Designs of Salinas, California. The American version also served as the wing for the "Jetwing" trike also produced by Flight Designs. After Flight Designs was bought out by Pioneer Parachute in 1982, some sails were made by the latter company. These were highly inferior to the original versions, and can be identified by the use of straight-stitch seams rather than zig-zag seams.

Deltaplane Deltaplane : Vision
Français Envoyer traduction
English This was not an Airwave glider, although Airwave did produce later versions of the Vision Mark 4 and Vision Pulse under the "Calypso" name. It was produced by Pacific Windcraft, of Salinas, California, from 1982 to 1985, when it was replaced by the Vision Eclipse. At one point, a few Vision sails were shipped to manufacturers in England and France, where they were fitted onto locally made airframes.

The Vision was the first double-surface glider to use a harder cloth for the main body and a softer cloth for the double surface, a configuration that allowed for higher camber at the loads experienced in landing. This resulted in a glider that was nearly as easy to land as a single-surface glider while providing a speed range more characteristic of a double-surface glider.

It was designed by Jean-Michel Bernasconi, with some help on the sail from me, as I was the head sailmaker for Pacific Windcraft.

Deltaplane Deltaplane : Sierra
Français Envoyer traduction
English The Seagull Sierra, designed in 1980 by Tom Peghiny, was Seagull's only double-surface glider. I do not believe it was ever offered for sale, as Seagull went defunct before the glider was HGMA certified. I remember a few prototypes flying in 1980; these were reported to have good performance but poor handling characteristics, possibly due to a very tight sail and insufficiently flexible airframe.

Deltaplane Deltaplane : Seagull 4
Français Envoyer traduction
English The Seagull 4 was almost identical to the Seagull 3. The most conspicuous difference was a cambered, S-shaped keel instead of a straight tube. I believe it also had a two-piece swept-back cross-brace rather than a single tube.

Deltaplane Deltaplane : Cirrus 5b
Français Envoyer traduction
English The Cirrus 5 was introduced in 1977 in four sizes, with the C5A being the largest and the C5D being the smallest. The C5B had a keel pocket and six flexible battens per side. Although designed for the novice pilot, it was quite tail-heavy and inclined to tip-stall during low-speed turns. Its handling and sink rate did not approach that of the Olympus, but it had better penetration at speed. Manufacture was discontinued in 1981.

Deltaplane Deltaplane : Eagle
Français Envoyer traduction
English The Eagle was never really a hang glider, being intended for motorized flight. As far as I know, it was foot-launched only once, as part of an early FAA requirement for ultralights, by one of the factory pilots.

Deltaplane Deltaplane : Dove
Français Envoyer traduction
English This was intended as a successor to the Cirrus 5, without deflexors but with a sail cut to compensate for the leading edge's bend under load. For its time, it was a decent "floater" but didn't have the speed range of the Cirrus models. Since it was lighter than most gliders of the time, it found some use as a trainer for novice pilots.
