UP-AS90
 
The AS-90 design is a development of the high performance Mark II Dragonfly technology to a standard Rogallo glider. It incorporates foam core sandwich construction, tapered batons and applied leading edges. This resulted in improving the glide ration and minimum sink rate, and quicker ive recovery made possible by the battened, roach tip sail design.
 
The AS-90 features an adjustable centre of gravity control bar mounting bracket, and adjustable dihedral and reflex with shackle system on the control bar.
 
The leading edge spars are 6061-T6 1.5in x 0.49 aluminium tubing and keel and cross-spar are 1.5in x 0.49. Ultralite Products saddles are at all tubing joints to distribute loading over the tube surfaces.
 
The cables are 304 3/32in 7x7 stainless steel, and all gradw 8 aircraft bolts, washers and nuts. Stainless steel nose plate, tangs, control bar bracket and kingpost bracket are fitted.
 
The sail is Howe & Bainbridge 3.8 oz stailised dacron, with applied leading edge pockets for minimum airfoil distortion.
 
The 6061-T6 1in x 0.83 aluminium control bar is anodised, and can be rigged for prone or seated flying wth optional ‘flip-flop’ rigging.
 
The AS-90 has a solid feeling in the air and reported as easy to takeoff and land. A design for beginners, it is built to the limit of the FAI rules. Very gentle stall characteristics permit highly controlled parachute descents.
