The Sorrell SNS-7 Hiperbipe is a two-seat, negative stagger, conventional landing gear-equipped cabin biplane designed for amateur construction that was produced in kit form by Sorrell Aviation of Tenino, Washington.[1]

Design and development

The SNS-7 (Sorrell Negative Stagger, Model 7) was intended to give full unlimited aerobatic performance without sacrificing the comforts of a cabin-style aircraft.[1]

The Sorrell family originated from the state of Oregon, which was the last state to ban homebuilt aircraft. Hobie Sorrell petitioned congress for experimental aircraft regulations, and his son Tim designed the Hiperbipe in a series of family designed homebuilt aircraft.[2] The design is of mixed construction. The fuselage, tail, engine mount, landing gear mounts, interplane struts and flight controls are all built from welded 4130 steel. The wings are made from wood, with wooden stressed skin. The landing gear is sprung steel tube. The engine cowling and wheel pants are fibreglass. The whole airframe is covered in doped aircraft fabric, including the plywood-covered wings. The airfoil is a custom symmetrical design.[1][3]

The SNS-7 is capable of advanced aerobatics, including vertical eight point rolls and inside and outside vertical eights.[1]

The Hiperbipe kit has been out of production since the 1980s.

Operational history

In April 2010 there were 22 Hiperbipes registered in the USA, two in Canada and one in the UK.[4][5][6]
