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:

- The fuselage is comprised of a welded tubular alloy-steel cockpit structure and riveted aluminum tail cone (with internal anti-corrosion primer).

- Riveted aluminium-alloy wings, horizontal and vertical stabilizers.

- All control surfaces and flaps are of aluminum alloy covered with 90 gr/m2 Dacron fabric.

- Engine mount and wing struts in CroMoly steel, cockpit door frames in aluminum-alloy.

- Alloy-steel exhaust system.

- Fuel quick drain.

- Battery.

- Polycarbonate side windows, ceiling and windshield.

- Aluminum wing tanks and 5 liter header tank.

- Composite wing tips, stabilizer tips, cowling and internal panels.

- Blank instrument panel.

- Leaf spring main gear, front fork and wheels complete with disk brakes.

- Rudder pedals, flap control system and joysticks.

- Control cables, small parts for the complete assembly.

- Padded leather seats.

Approximately 200 hours are required to complete the aircraft. Not included in the kit: engine, propeller, instruments and paint.
