Powered by a simple rubber-band propulsion system, this kit provides a low-cost, repeatable way to learn the basics of model aircraft construction and flight. It’s well-suited for hobbyists seeking a satisfying build-and-fly experience that builds practical skills and serves as a stepping stone to more advanced kits in the series.
