Deltaplane : Esprit
Français		Envoyer traduction
English	The Esprit was not an Airwave glider. It was produced from 1983 to 1985 by Pacific Windcraft of Salinas, California. Intended as a higher-performance version of the Vision, it was particularly popular as a tow glider behind the La Mouette trikes that PW as importing. There was only one Esprit ever made that doubled as a trike glider. I owned it. Due to its higher weight, its sink rate was poorer than the stock ones when flown unpowered, but the stiff frame gave it better penetration and glide at speed.

Deltaplane : Asg 23
Français		Envoyer traduction
English	I'm not sure Randy's right about this being an ASG-23. If it was made in 1979, I think it was an ASG-25, since Tom Price had already been hired by Electra Flyer by spring 1978. (That was when I came to work for Electra Flyer, and Tom was already there.) I remember helping Tom make a couple of these sails and fit them to a crossbar-less frame with fiberglass leading edges. The ASG-23, as I recollect, was a more conventional glider with crossbar, preformed ribs, and fiberglass leading edge tips to tension the trailing edge at the tips, much like the Stratus gliders. (I don't think the crossbar was enclosed.) It went out of production in the winter of 1977-1978, when Tom closed his own sail loft and went to work for Electra Flyer. I remember seeing some stored ASG-23 patterns in the sail loft there, but no sails were made from them.

Deltaplane : Vulcan

English	I worked at the Electra Flyer factory when this glider was being developed. It was an attempt at a bowsprit glider to compete with similar designs from other manufacturers. I seem to recall that it lacked pitch stability and had too much spiral instability for comfortable thermalling. Its sink rate was also unacceptably high, according to the test pilots I talked to at the time. At any rate, it was not a successful design, and never saw production.

Deltaplane : Spirit
Français		Envoyer traduction
English	Introduced in 1980, the Spirit was the successor to the Floater, with a simplified sail cut but retaining the Floater's general planform and hinged cross-spar. The sink rate suffered somewhat from the modifications, but it was fairly maneuverable and easier to launch and land than its predecessor. I owned and flew one of these about a year and a half, accumulating many hours of mountain thermalling, before selling it to buy a Flight Designs Javelin, which was better suited to dune soaring.

Deltaplane : Floater
Français		Envoyer traduction
English	Designed primarily by Tom Price (with some input from Tom Peghiny and Larry Newman) and released in 1979, the Floater was Electra Flyer's first attempt at a glider to compete with the Moyes gliders and La Mouette's Atlas, both of which employed light wing loading to achieve a low sink rate while still offering some glide at speed. While it achieved both goals, it turned out not to be competitive with its rivals. It remained in production for a year, being replaced with a somewhat smaller version called the Spirit which, while it did not have the Floater's sink rate, was more maneuverable and easier to fly. The largest size floater was a popular tandem glider in the early 1980s.

Deltaplane : Space

English	Easiest hang glider to land that I have ever flown. Period.

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 : 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 : 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.
