STEM Inventions 6Inch Plastic Propellers 10Pack Build Rubber Band Powered Planes Helicopters and More STEM Projects

Designed for STEM Projects This 10pack of 6inch plastic propellers is specifically engineered for rubber bandpowered creations including model airplanes helicopters and propellerdriven cars Easy to Use The propeller assembly mounts securely onto standard craft sticks popsicle sticks or balsa wood measuring up to 0135 by 035 inches providing a reliable foundation for building Directional Thrust Control Featuring a builtin 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 highquality steel and semiflexible plastic The plastic blades are resilient enough to withstand minor to moderate impacts while the steel shaft resists bending during normal use.
