This composite design came from German engineer Horst Ruschmeyer. Solaris Aviation, Inc., a U.S.-based company, purchased the assets of Ruschmeyer Aircraft, GmbH in 1999. Each model of the Sigma differs purely by horsepower. The tapering wings have a 6.97 aspect ratio, a laminar-flow airfoil, leading-edge stall strips and tilted wing tips. The small ailerons have slight differential action, with deflection limited by concealed massbalances. Inboard are large, three-position, electric Fowler flaps with similarly shrouded hinges and mechanisms. All models feature retractable trailing link landing gear and gull wing doors. The airframe is designed to 9 Gs.
