Guillow's Fly Boy STEM Balsa Wood Model Airplane Kit - Level 4

The Fly Boy is the fourth and most advanced model in Guillow's Build-N-Fly construction series, a rubber-powered balsa wood airplane that actually flies. This kit represents the capstone of a structured learning progression designed to take builders from basic gliders to a stick-and-tissue model with a box fuselage. Made by the Paul K. Guillow Company, the series teaches model airplane construction and flight step by step, with the Fly Boy requiring skills developed through the earlier three levels. Rubber-band powered flight mechanism launches the completed plane into real flight Fourth skill level in a four-model series that builds construction techniques from simple to advanced Balsa wood construction teaches hands-on engineering and aerodynamics through assembly Box fuselage and stick-and-tissue design offer more complex building challenges than earlier series levels
