Maverick Twinjet 1500
Bob Bornhofen was retired when he got into the aviation business, and had no aviation background. He wondered why he couldn't buy a personal jet, and in 1998 he decided to create one. Bornhofen has been funding much of the project out of his own pocket.
To be marketed as a kit, the Twinjet has a pre-preg eglass composite airframe with carbon fiber control surfaces and empennage.
The TwinJet was not certified because it uses two converted surplus GE-T58 military helicopter engines (overhauled and zero-timed).
The TwinJet was designed in anticipation of the FJX-2 engine, which was being developed under the General Aviation Propulsion program. The FJX-2 was going to be a new generation turbofan engine producing 700-800 pounds of thrust.
When delays occurred for that engine, Bob Bornhofen elected to use the T58 engines so he wouldn't slow the TwinJet development.
