Pacific Gull HA Series

The HA Series is a design extension of the basic Rogallo. Aith an increased aspect ratio and less surface area it offered a higher glide ratio than a standard Rogallo. It is both stable and aerodynamically balanced, has no tendency to flat spin, and exhibits excellent dive recovery.

The HA Series had more adjustments than any other glider. It is equipped with two adjustable keel channels to tune keel bow and control bar postion, reversible wires to permit seated or prone flying without re-riging, three centre of gravity positions, three upper rigging turnbuckles, seven positions for wing dihedral, and optional three position sail billow and riser kit. It has eight ball-lok pins and a sliding-wing folding cross bar syatemtp let any adjustments be made in 30 seconds and completely set up in 3.5 minutes.

The airframe is made from 6061-T6 1.5in x .058 anodised aluminium. Aluminium inner-compressin bushings are used in place of wooden doweling. The rigging cable in 3/32in 7×7 vinyl covered stainless steel. All hardware is anodised stainless steel.

The sail is made from 3.8oz Howe & Bainbridge stabilised dacron, then available in 11 colours.

There was the options of seated, prone or combination rigid/flexible sitting harness with back rest and front strap.

Pacific Gull Alpine

The Alpine is a double surface, battened, flexible sail, high performance glider. Speciffically designed for cross-country soaring, it features no low speed yaw, dampened pitch response, keel reflex and tip washout behind the centre of gravity by over four feet, acting as “up” elevator.

The Alpine is equipped with cross-bar, keel adjustment channels, front mast cable tensioner, adjustable centre of gravity, reversible lower wires to allow seated or prone flying, and fully ball-lok pin for quick set-up. The glider features truncated tips for wash-out adjustment and exact tuning.

Te airframe is made from 6061-T6 anodised aluminium. The keel is 1.5 in x .058, crossbars are 1 5/8in x .058 and leading edges are 1.75in x .035. The keel is precambered to a specific shape. Leading edges are reinforced with plug-in deflexers.

Cables are 3/32in 7×7 nylon coated stainless steel. All hardware is anodised aluminium and stainless steel. There are custom injected molded batten tips, spar saddles, and aluminium extrusions.

The sail is a double surface stretched membrane made from 3.8 oz Howe & Bainbridge dacron in 11 colours. The sail has 10 pre-bent aluminium cambered battens.

There was the options of seated, prone or combination rigid/flexible sitting harness with back rest and front strap.

Pacific Diffusion Select

Produced at Kembs-Loechle (Franse) close to Mulhouse, by Pacific Diffusion, the select was a 1986 hang glider for advanced pilots. Chayrou produced the Select, a copy of the Express which he made before at Oderen.

The Select could reach 80+ km / h without disproportionate effort. The large model was stable spiral, which was not the case with the small size, which had no keel pocket.

Select 140
Wing area: 14 m²
Wing span: 10 m
Aspect ratio: 7.15
Hang glider weight: 23 kg

Pacific Diffusion

André Chayrou, starting from plans made by the manufacturer Pacific Kites, was the owner of Pacific Wings until 1985 (purchased by Aérotech).

On his departure from Oderen, Andre Chayrou created in 1985 “Pacific Diffusion” and moved to Kembs Loechle, near Mulhouse to make the “Select”, which was none other than the Express.

Hang glider builder

Orion Delta Tee

A 1990 hang glider for Intermediate pilots from Switzerland. Very balanced wing on all axes, and very pleasant to fly. It has a very slow flying regime that allows it to climb very well in thermal. It is a bit slow to reverse turns, and must be anticipated.

Minimum pilot weight: 65 kg
Maximum pilot weight: 95 kg

Offpiste Discovery

The 1996 Discovery was designed as a Skyfloater. It was aimed at those pilots wishing to fly for fun having found that the latest superships are demanding of skills especially in light wind conditions.

The 1996 Discovery was available in two sizes: 160 and 195. A feature of the Discovery is that it can be flown prone or seated.

Discovery 2

The 1997 Discovery 2 catered for all weights of pilot by four sizes: 160, 195, 195S and 210. The price was £1750, rising to £1800 for the 195 S version. A retro-fit kit was available for around £100 to upgrade the Mk 1 to Mk 2 spec.

The 1997 Discovery 2 was described as glorious in light conditions due to low wing loading and featherlight handling, however once you pull the bar in more than a few inches glide and sink rate are terrible.
