Pacific Gull HA Series
 
Pacif-Gull-HA-01
 
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 7x7 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.
