It has an easy to follow instruction manual that my son was able to figure out on his own. It is empowering for children to be able to build their own toys, and see the mechanism that goes into making it. It can be used to instill self confidence in children, as they will be pleased and blown away to be able to create a robotic machine from pieces. It includes 3 different colored propeller flyers, and over 80 snap together pieces.
My son was skeptical at it's ability to fly over 30 feet in the air while building, but was blown away not only at how high it was able to fly, but how easy it was to use and play! Children simply pull the zip-cord stick to release, the faster they pull, the higher it goes. It builds strong as the pieces do not fall apart easily once snapped into place, so children are able to actually use it and play with their creation. The VEX Robotics Zip Flyer gives two ways to build, allowing the zip flyer to launch straight up or as a Side Winder by building it with an angle. It does not require any batteries to operate, and it set at an affordable rate of $12.99. Additional information and where to buy can be found here.
