Thin plywood skins form much of the aircraft’s exterior structure.
03 — Carbon
Carbon is used selectively in structural areas, including spar caps and reinforcement.
04 — XPS foam
Lightweight XPS foam is used in parts of the wing and airframe structure.

Built, not just assembled.
Inside the Spacek factory: wood, plywood, foam and composite, cut and glued and bagged and sanded by people at benches. That is how these airplanes are made, and a kit is the same work handed over partway through.
