  • Functionality of Propeller: the design of the red plastic propeller, with its built in shaft and small hook, is specifically made for being powered by rubber bands; The propeller of our rubber band helicopter kit will only allow you to wind it one way; With its thoughtful design, the kit offers that the direction of energy release is always right; Our propellers for stem projects are suitable for a wide range of STEM projects, including propeller planes, and propeller powered cars

  • Energy Release Manipulation: for those with an interest in energy manipulation, this plastic propeller kit enables altering the rate of energy release; Using a single rubber band allows a slower rate of energy release, while combining multiple bands can facilitate a much faster burst of energy, giving you the control to observe and analyze variations in energy transformations

They don't work. Wind one up and toss it in the air - the body spins instead of the propeller.

Thought this would at least fly a little bit, but nope straight to the ground.

Too cheaply made. Failed to function. Many children sad.

For their helicopter usage, these are so-so. Using them to turn gliders into fun-to-fly airplanes, much better. However, the back hook that attaches the rubber band opposite of the propeller, is a tad flimsy and cheap. The rubber band is mostly strips of rubber that you fashion into a band for various amounts of strength. The back hook is not meant to hold a whole lot of tension, so we've had a couple failures due to that. Other than that, this is a nice kit for hobby projects
