UP-Brock
 
The standard Rogallo Brock 82S was a favourite for beginners. Easy to handle n the ground and with predictable flight characteristics, a sensitivity to control makes it ideal for ridge lift soaring.
 
It has a one piece stainless steel aero dynamic nose plate for hole alignment and an adjustable centre of gravity control bar mounting bracket.
 
The airframe is made from 6061 T-6 aluinium tubing with spars 1.5in x .049 and sleeves 1 5/8in x .058. Special Ultralite Products saddles are used at all tubing joints to distribute loading. The control bar is 6061 T-6 1in x .083 aluminium which was available in 40in, 44in, and 50in sizes. A swing seat was included.
 
The sail is Howe & Bainbridge 3.0 or 3.8 oz stabilised dacron. Individually sewn from to a combination choice of 11 colours. The rigging cable is 304 3/32in 7x7 stainless steel. Flying wires are not adjustable. Landing wires are turnbuckle tensioned.
