Volume 3 continued with another 15 new models, many of which were named after famous aviators. The rainbow logo was switched back to the plain blue color and a “Certified Edition” banner was added to the corner. This volume made several design improvements. It dropped the metal hooks used by the rubber band catapult and replaced them with built in paper notches. This made the construction easier for beginners. The kit also dropped the usage of lead as nose weight for balancing the aircraft. This also made construction easier, but more importantly, it was no longer toxic! This set debuted the “TriLinear” series of gliders and continued with the "Racer" and "Light Plane" series.
