Rewrite the text to focus on the V912 helicopter, its blades, and the user's experiments with 3D printing. Mention the three types of blades tested, their features, and the effects on stability and flight time. Also include details about the 3D printed canopy and mention that a video is available to see the helicopter in action. End with an update on the latest blade design and the printing method used for the lightest version. The V912 RC helicopter boasts a 40cm main rotor diameter and 4-axis control. The user has experimented with various 3D printed blades, testing three different versions. The original blades were nearly identical to the originals, while two others aimed for more silence. Increasing rotor speed improved stability but reduced flight time, making it ideal for small indoor spaces or windy conditions. The second blade version was slightly quieter without scientific measurements. The user also 3D printed a canopy with ongoing improvements using the "vase" technique. A video demonstrates the helicopter in action. The latest design features improved original blades with a smooth shape for stability and silence. Printing the lightest version used "perimeter only," vertical blade placement, 0% infill, three shells, and a 0.25 height.
