Description

  • Designed for STEM Projects: This 10-pack of 6-inch plastic propellers is specifically engineered for rubber band-powered creations, including model airplanes, helicopters, and propeller-driven cars.
  • Easy to Use: The propeller assembly mounts securely onto standard craft sticks, popsicle sticks, or balsa wood measuring up to 0.135 by 0.35 inches, providing a reliable foundation for building.
  • Directional Thrust Control: Featuring a built-in propeller shaft with a small hook for rubber bands, the design only permits winding in one direction. This ensures the generated thrust consistently moves your project forward.
  • Adjustable Performance: The propellers generate substantial lift and thrust. Builders can use a single rubber band for a slower, sustained energy release, or double the rubber bands for a quicker, more powerful burst of energy.
  • Durable Materials: Constructed with high-quality steel and semi-flexible plastic. The plastic blades are resilient enough to withstand minor to moderate impacts, while the steel shaft resists bending during normal use.

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.
