Designer : Scott Hanchette

Originally conceived to use a piston engine driving a five- or six-blade pusher propeller, brothers Scott and Dan Hanchette commenced work on the prototype, then known as the ViperFan, in February 1996.

However, concerns about the difficulty and cost associated with eliminating vibration from the drivetrain led the Hanchettes to choose turbojet propulsion instead, and they installed a Turbomeca Marboré engine in place of the Continental flat-6 they had originally envisaged as a powerplant.

The Viperjet prototype flew late in October 1999 and made its public debut at EAA AirVenture Oshkosh in 2000.The Hanchette brothers, however, were unhappy with both the low power and the high fuel consumption of the Turbomeca engine, and soon swapped it for a General Electric T58 turboshaft engine with the power turbine removed, turning it into a turbojet.

While this worked, it still did not produce as much thrust as the Hanchettes hoped for, and eventually, they selected the General Electric J85 With this engine producing around four times the thrust of the previous powerplants tested in the Viper, the Hanchettes substantially redesigned the aircraft, dubbing the J85-powered version the MKII The prototype was dismantled and rebuilt, with parts of the canopy and fuselage center section all that remained of the original design.

The slightly larger MKII also features a pressurized cabin, nearly three times the fuel tankage, stronger undercarriage, and optional tip tanks.The MKII prototype flew on 12 June 2005 and Viper Aircraft offered replacement MKII parts to all customers who had purchased kits of the original version, now dubbed the MKI.

In 2006, the base MKII kit cost US$182,000, but since builders can purchase additional components already pre-made by Viper Aircraft, customers spent an average of $350,000 on their kits. They would then have to spend approximately another $300,000 and around 3,000 to 3,500 hours to complete the aircraft. The company also offers customers a builder assistance program to help them assemble the major airframe components and a training program to help them learn to fly their ViperJet once it is complete.

Zero Gravity Builders provides builder assistance for the ViperJet MKII, ViperJet LXR and Viper FanJet. Viper Aircraft had sold 21 kits by September 2006 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 ViperJet, as well as a UAV version.
