Lark II
 
The Lark II is an improved version of the standard Rogallo. A nose anle of 90 degrees, slightly cut keel, roach tips and two battens, giving better glide and soaring performance plus much improved stability and handling over standard Rogallos. It also has stronger than usual tubing.
 
Breakdown capability for shipping at about half the leading edge/keel length. Rounded nose plate help prevent sudden stops and rigging can be easily adjusted for either prone or seated flight. Options included harness and storge cover. An owner’s manual was included.
The airframe is made from aircraft grade 6063-T832. Sizes varies from 1½ x .049 in to 1 7/8 x .058 in. Dowelling is not used for lighter weight. Strength comes from stainless steel bushings and inside sleeving.
 
Marine stainless steel 3/32in 7x7 is used throughout with protective coating on bottom wires. Quick links and pins are used so rigging and control frame can be quickly removed. All hardware is of stainless steel or aircraft quality aluminium. Nuts, washers, bolts and turnbuckles are aircraft grade.
 
The sail is 3.0 oz dacron with double zig-zag stiching and was available in seven standard colour patterns from one to five colours.
Either a “bikini” harness, swing seat, or supine harness were available.
