VEX Robotics Zip Flyer by HEXBUG
This robotic gadget is capable of shooting propellers over 30 feet in the air! Pull the zip-cord stick to release, the faster you pull, the higher they’ll go. The excitement doesn’t stop there, the VEX Robotics Zip Flyer can be built for both hand-held and tabletop action. Two ways to build, two ways to launch.
