Sorrell SNS-7 Hiperbipe with an unusual registration at the Boundary Bay Airshow.
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.
The SNS-7 is capable of advanced aerobatics, including vertical eight point rolls and inside and outside vertical eights.
The Hiperbipe kit has been out of production since the 1980s.
In April 2010 there were 22 Hiperbipes registered in the USA, two in Canada and one in the UK.
