Carbon Fiber Structure

Carbon fiber tubes form the structural skeleton of the Stork — wing spars, motor booms, and reinforcement — delivering rigidity at a fraction of aluminum's weight.

Why Carbon Fiber

The Stork's LW-PLA airframe is lightweight but needs internal structure to handle flight loads — bending forces on the wings, motor vibration, and landing impacts. Carbon fiber tubes provide that structure.

Carbon fiber offers the highest strength-to-weight ratio of any practical structural material. A 10 mm carbon tube weighs a fraction of an equivalent aluminum tube while matching or exceeding its stiffness.

Structural Applications

Wing Main Spar

10 mm round

Carries all bending loads during cruise flight. The main structural element of the wing.

Wing Secondary Spar

8 mm round

Supports trailing edge, mounts control surfaces, and adds torsional rigidity to the wing.

Wing Rib Spars

6 mm round

Connect ribs to the main spar structure. Distribute aerodynamic loads across the wing skin.

VTOL Motor Booms

10×10 mm square

Mount the four lift motors to the wing. Square profile resists rotation and provides flat motor mounting surfaces.

Strength without weight

Every Stork includes a full carbon fiber structural kit, cut and fitted to the airframe.
