Manta Pegasus
The Pegasus is a high performance truncated-tip Rogallo that can be handled by intermediate level pilots. It features high penetration and quick roll response yet has a gentle stall. Its sail is cambered, roached, and truncated with pockets of pre-formed ribs, applied leading edge pockets and applied keel pocket. The high aspect ratio and generously cambered sail give both low minimum sik and high L/D.
The control bar is fully adjustable for prone or swing seat flying, folds down easily for carrying, has neoprene cushioning and optional wheel assembly. The Pegasus also features adjustable keel reflex, optional take down to 6 ft 6 in, and no tool set-up or take-down.
The airframe is made from 6061-T6 1.in x .049 anodised aluminium tubing with hardwood dowels and with bushings. Rigging cable is 3/32in 7×7 stainless steel with snap-on cable cover optional. The cabling is double swagged at every connection point.
All bolts are AN os MS quality, self-locking nuts. Stainless steel noseplate, tangs and thimbles. The sail is made from 3.8oz stabilised dacron, double zig-zag stitching, reinforced at stress points, spar-flex compensation for clean inflight shape, perpendicular-sewn seams for dimensional stability, and was available in 10 colours.
The Pegasus came with a flying seat with individual leg straps, or optional harness.

Manta Fledgling / Fledge / Voyager
A 1974 hang glider for advanced pilots. The Fledgling uses two identical spars that carry equal loads. The rear spar is in a streamlined pocket. The Fledgling is completely self-launchable and folds down to a Rogallo size package. The rudders that aid stability and turning are actuated by control cables attached to the swing seat, harness or by twist grip, supine.
The airfoil remains rigid in flight by use of pre-formed, removable ribs. No tools are required for set-up. The spars are made from 6061-T6, 1.5in x .049 tubing and rigging cable is 3/32in 7 x 7 stainless steel. All hardware is aircraft quality.
The sail is made from 3.8oz stabilised dacron, then available in 11 colours. A flying supine seat with individual leg straps, or prone harness were optional.
Some of the greatest characteristics of the Fledge was the ability to penetrate high winds. It was always fun to spin.
The Fledge 2 was a 1980 hang glider.
The Fledging IIB was motorized to give the Pterodactyl Fledging, one of the first ULM.
The 1983 Fledge 3 was nasty in a spin when the center of drag (the Fledge) traded places with the center of mass (the pilot). Next thing, flying upside down at 1 negative G. Some say it was an absolute bitch to rig and weighed a ton and ground handling was terrible, trying to get used to yaw induced roll.
The Fledge Voyager was a 1980 version for advanced pilots.
The 3ET (extending type) has 1.50 m extra on each side plus and Casper shutters that augers the potence at the wingtip in turn it turns flat, does perfect loops at + 6g positive and negative.

Magnan Sundance
Sundance is a high performance, single surface swept tailless monoplane of constant chord. The Sundance system of constructin breaks down into a Rogallo size bag. The SSundance employs drag rudders for positive turn response while longitudinal control is achieved through weight shift. Spoilers were also optional, interconnected with the drag rudders.
The airframe is made fro 2024-T3, 1.75in x .035 wall for the leading edge, 2024-T3 1in x .049 for the struts and trailing edge. All tubes and parts are 100% bright dip anodised in three different colours: black, red and clear. All stress points on the tubing are sleeved reinforced.
Rigging cable is aircraft 3/32in 7 x 7 302 stainless steel with continuous top rigging and double nico pressed. Tangs, shackles, and nose plates are 305 stainless steel. The strut brackets, kingpost plug, drag rudder plugs, and elbow joints are machined from 6061-T6 alumnium and bright dipped anodised. Nuts, bolts, washers, and turnbuckles are aircraft quality.
The sail is Howe & Bainbridge 3.8oz stabilised dacron. All seams are double and single zig-zag stitched and stress points are reinforced. All sails came with Velcro fastening. There was a choice of 11 colours.
Special hardware include injection molded plastic saddles, micro-balloon tips for the ribs, and compression plugs for structural integrity.
The Sundance was provided with a seated harness. The prone harness is constructed of 8oz para’pac nylon and 1in foam. Webbing is a combination of 8000 lb test web for attachment points and 2000 lb test streamlined tubukar web for the suspension lines. Seats and supine harness are constructed of injection molded polyurethane plastic. Web is 5000 lb test.

With a wider than average span, the lateral control is very responsive, partially due to the roached tip design which increases washout under loading. Pitch control is responsive but not sensitive to minor control because of dampening. It is stable on all axis, and no spin tendency and parachute landings can be made without problem of dropping off.
The Harrier IV features a precambered keel and precambered full length ribs throughout the sail. It came with 66in bar, double deflexers, 100% anodised in black, red, or clear.
The airframe is made from 2024-T3 1.75in x .035, 6061-T6 1.75in x .049 leading edge, cross bar and keel, 6061-T6 1in x .083 for the control bar, and 2024-T3 1in x .049 for the kingpost. All holes are sleeved, dowled and bushed.
Rigging cable is aircraft 3/32 7×7 302 stainless steel with continuous top rigging and double nico pressed. Tangs, shackles, and nose plates are stainless steel. The kingpost bracket, control bracket, kingpost plug and elbow joints are 6061-T6 aluminium. Deflexers are made from machined 2024-T3 aluminium. Nuts, washers, bolts, and turnbuckles are aircraft quality. All aluminium components are bright-dip anodised either red, black, or clear. All steel components are polished.
The sail is Howe & Bainbridge 3.8oz stabilised dacron in a choice of 11 colours. All seams are double zig-zag stitched and stress points reinforced. The sail is designed with roached tips for improved efficiency and stability. Each sail came with Velcro fasteners for the ribs.
