These ready-to-mount propellers are ideal for makers, hobby engineers, and anyone who wants to build rubber-band powered aircraft. The built-in propeller shaft, rubber band hook, and plastic mount makes it effortless to slip the propeller onto a wooden fuselage and start crafting your invention. Works great with regular 4.5" long craft sticks! Note: This product does not include craft sticks or rubber bands.
Made with high quality steel and plastic!
Semi-flexible plastic is resilient enough to withstand minor to moderate crashes, and the steel will not bend under normal use
Generates plenty of lift and thrust!
Try using a single rubber band to release energy at a slower rate, or try doubling rubber bands to spend less time winding it up and to get a faster burst of energy
