The Viper Jet MKII is a jet aircraft designed and produced by Viper Aircraft Corporation in kit form for homebuilding. It is a conventional, low-wing monoplane with swept wings and tail and two seats in tandem under a bubble canopy. The jet intakes are located at the sides of the fuselage and the tricycle undercarriage is retractable. Construction throughout is of composite materials. In 2008, Viper Aircraft announced an enlarged, turbofan-powered follow-on design as the Viper Aircraft FanJet. The company has also proposed a military trainer version of the Viper Jet, as well as a UAV version. The Viper Jet MKII is consequently designed as a very lightweight composite and balsa/ply built-up structure, with features similar to a world class F3A-Pattern plane. Lightest lay-ups, perfectly engineered aerodynamics and structural reinforcements only where they are needed; this model is perfectly suited for electric ducted fan flying. The pre-installed fiberglass intake ducting is engineered for efficiency and pure performance, making this aircraft capable of extreme speeds with just stock Sapac MB1 motor and Sapac EDF system. ARF lets you use the provided fixed landing gear system, but it is also designed for the optional Sapac RZ180 pneumatic retract system with scale set of spring loaded struts. The Viper comes with a full hardware package and illustrated instruction manual.

The Viper Jet is a high-performance ducted fan model with an incredibly sleek design, a real rocket ship in the making!
