Structure

Fuselage:

The semi-monocoque structure uses plywood sandwich formers and bulkheads, with laminated wood longerons placed in the corners and a plywood skin. The frames are made with a water-jet cutter.

Wing:

The wing uses a semi-monocoque structure with plywood ribs, carbon or wood spars and webs, and a plywood skin. The ribs are made with a water-jet cutter. The wing can be removed while the aircraft is on its landing gear, which makes maintenance and repairs easier.

100% mass balanced ailerons, frames plywood sandwich, laminated wood stringers. Fabric covered.

Horizontal tail:

The stabilizer uses a semi-monocoque structure with plywood sandwich frames, laminated wood stringers in the corners, and a plywood skin. The elevator is fully mass-balanced and built with plywood sandwich frames and laminated wood stringers. It is covered with fabric, and the horizontal stabilizer can be removed.

Vertical tail:

The stabilizer uses a semi-monocoque structure with plywood sandwich frames, laminated wood stringers in the corners, and a plywood skin. The rudder is fully mass balanced and built with frames, plywood sandwich, and laminated wood stringers. It is covered with fabric. The vertical stabilizer is integrated into the fuselage.

Cockpit:

Seat

Fixed seat with three fixing positions (fore/aft) attachment for FIA approved "car race-seat". Four or five point seat belts. Seat and belts are fixed to safety cage, which forms strong structure for central part of fuselage.

Obvious

All homebuilt aircraft use these purchased parts. Many people may not realize how easy it is to buy these items or semi-finished products. Examples include the engine, propeller, sheet material, screws, bolts, nuts, cables, instruments, safety belts, paints, wheels, rims, and tail wheel.

Not so obvious

Fuel tank, seat, landing gear spring.
