Home-Built Engine Designes

GTBA Engine

The GTBA Engine is a work in progress engine designed to be easy to build and inexpensive to obtain. The engine is designed around a turbocharger impeller/turbine pair. The engine is designed to be easy to scale so that members can build one using any turbocharger they can obtain.

UT-160

The UT-160 is a modern design available for homebuilders. Plans are available as CAD files and the wheels are available via jetmax.ch. The engine is easy to build and is a favorite for modification with GTBA members.

MW54

PARTS NO LONGER AVAILABLE

The MW 54 is a modern design available for homebuilders. The engine is different to all the other engines. It is much smaller and lighter, and is slightly less powerful at 10 lbs thrust. Plans are now available for the turbo prop attachment.
