Manta 80S
 
The Manta 80S is a standard Rogallo developed for beginning through advanced pilots. It is stable, predicable, and responsive when tracking or turning. The 80˚ nose angle gives high penetration qualities and wide speed range.
 
The 80S airframe is of 6061-T6 1.5 x .049 in anodised aluminium tubing with hardwood dowels and bushings. Cables were 3/32in 7x7 stainless steel with snap-on cable covers optional. The cables were double swaged at every connection. All bolts are AN or MS quality, nuts are self-locking, and noseplate, tangs and thimbles are stainless steel.
 
The 80S sail is 3.8 oz stabilised dacron, double zig-zag stitched, reinforced at stress points, with spar-flex compensation for clean inflight shape and perpendicular-sewn seams for dimensional stability. It was available in 10 colours.
 
The 80S came with a flying seat with individual leg straps or optional prone harness. The control bars is fully adjustable for prone or swing seat, folds down for carrying, has neoprene cushining and optional whel assembly. The 80S also features adjustable keel reflex and optional take down to 6 ft 6 in.

Manta 80SK
 
The Manta 80SK has a slightly shorter keel than the Manta 80 for a moderate performance gain and increased handling sensitivity. It has the same penetration stability and maneuverability characteristics as the Standard. The shorter keel relieves parasitic drag, improves speed and ncreases pitch response.
 
The Manta 80SK control bar is fully adjustable for prone or swing seat flying, folds down for transport, has neoprene cushioning and optional wheel assembly. They also featured adjustable keel reflex and optional take down to 6 ft 6 in, requiring no tools.
 
The airframe is of 6061-T6 1.5in x .049 anodised aluminium with hardwood dowels and bushings. The cables are 3 3/32 7x7 stainless steel with snap on cable covers optional. Double swagged at every connection point.
 
All bolts are AN or MS quality, with self-locking nuts, stainless steel noseplate, tangs and thimbles.
 
The sail is 3.8oz stabilised dacron, double zig-zag stitched, reinforced at stress points, with spar flex compensation for clean inflight shape and perpendicular sewn seams for dimensional stability.
 
The Manta 80SK2 was designed for intermediate pilots ready to advance to a higher performing glider. Its shortened keel increased the aspect ratio, improved pitch response and reduced parasitic drag. The 80SK2 has an increased speed range and greater maneuverability.
