The prompt
Create a solid parametric CAD model of a twin-motor high-speed RC airplane. The central fuselage is a lofted aerodynamic body, 500mm in length, 70mm in maximum width, and 60mm in maximum height to accommodate a large 6S battery. The fuselage tapers to a sharp conical nose at the front and converges to a thin edge at the rear. Attached to the fuselage are symmetrical swept-back wings, creating a total wingspan of 800mm. The wings have a thin, streamlined airfoil profile for high-speed flight. Merge two forward-facing cylinders into the leading edge of the wings, located 150mm away from the central fuselage on both sides. These cylinders are 32mm in diameter and 40mm long, serving as nacelles for twin motors. Add two small vertical stabilizers angled slightly outward at the rear of the fuselage. Apply generous fillets to all intersecting joints between the wings, nacelles, and fuselage to ensure smooth, aerodynamic airflow.
