The YUMA kit is highly prefabricated and the airframe can be considered 85% complete. This is well in excess of the so-called 51% rule that exists in various countries. The YUMA therefore has a very quick build time. The adjacent photos show the basic structure as delivered. The kit includes all components, material, and hardware needed to complete the airframe, however, the choice of engine, propeller, and instruments is left to the builder. The following summarizes the kit:
- Welded tubular alloy-steel cockpit structure and riveted aluminum tail cone (with internal anti-corrosion primer)
- Riveted aluminum-alloy wings, horizontal and vertical stabilizers
- All control surfaces and flaps of aluminum alloy covered with Dacron™ fabric
