The Sorrell Hiperlight is a family of single and two seat, negative stagger biplanes, designed for amateur construction.

[1][2][3][4][5] The design was sold initially by Sunrise Aircraft of Sheridan, Oregon and as of May 2022 was produced by Thunderbird Aviation of Ray, Michigan.

[2][3][4][5][6] The single seat SNS-8 Hiperlight was designed by the Sorrell brothers in 1982 at the request of the US Rotax engine distributor to provide an enclosed cockpit aircraft design to utilize the 28 hp (21 kW) Rotax 277 engine.

The resulting aircraft was a scaled-down version of the very successful Sorrell Hiperbipe aerobatic cabin biplane and with an empty weight of 247 lb (112 kg) fit the US ultralight category.

The aircraft has full-span ailerons on the bottom wing that droop together when the stick is pulled back, giving the same effect as flaps in the landing flare.
