Mini Rubber Band Flying Plane

Mini Rubber Band Flying Airplane – Assembly and Use Instructions Required Materials 2 x 20 mm rubber bands OR 1 x 45 mm rubber band (looped twice). How It Works The rubber band acts as the motor. It should be wound for about 30 turns (or more, depending on the elasticity of the material). When released, the rubber band unwinds rapidly: This rotation spins the propeller, generating thrust. As the airplane gains speed, the wings generate lift, allowing it to climb and fly for several seconds. Important Details Rubber band torque: 30 turns is the "sweet spot" for storing maximum energy without breaking the rubber band or deforming the frame. Propeller pitch: Ensure that both blades are angled evenly. Looking from the front, the blades must be slightly twisted in opposite directions from each other (like a screw) to effectively "bite" the air and create airflow.
