The wing spar is a safety-critical load path. During cruise flight, aerodynamic lift acts distributed across the wing panel while gravity and payload loads act at the fuselage attachment point — creating a bending moment that the spar must resist continuously. At cruise speed, this bending moment is substantial. A standard printed plastic spar will deflect excessively and may fail under sustained load. Chopped carbon fiber filament provides marginal improvement. Continuous carbon fiber — where the fiber runs unbroken from one wing root to the other — is the correct structural solution. The CCF spar in the GatorRay carries this bending moment exactly as a hand-laid composite spar would, at a fraction of the manufacturing cost and with the geometric freedom of additive fabrication.
