How can you make biplane?

To make a biplane, you'll need to design two wings stacked one above the other, ensuring they are structurally sound and balanced for flight. Start by constructing a lightweight frame using materials like balsa wood or aluminum, and attach the wings securely. Install a small engine for propulsion and control surfaces like ailerons and rudders for maneuverability. Finally, equip it with a landing gear system for takeoff and landing.
