Imagine a bird-like creature with a 40-foot wingspan, an eight-foot beak, and fierce talons soaring through the skies above you! Now you can build and fly a model of this incredible pterosaur, the Quetzalcoatlus — the largest flying animal of all time. Assemble the model and hang it from your ceiling with the included hardware. A battery-powered motor propels your Quetzalcoatlus through the air while a thin cable keeps it soaring along a circular flight path. Learn how the propellor makes the model fly, about the similarities between pterosaurs and modern-day birds, and all about this awe-inspiring giant of the prehistoric skies.
