LiPo (Lithium-Polymer) batteries are a popular means for powering our electric models. As is the case when working with any power source, there are a few things that modelers need to know to stay safe and keep their batteries performing.
Sir George Cayley, often called the Father of Aeronautics, designed a helicopter powered by a bow-string mechanism with feather blades (similar to the reproduction shown here). Later, he experimented by flying a model with multiple adjustable surfaces, allowing him to understand how every change affected the model’s flight. This model is a ½ scale replica of his original 1804 model. Cayley used the data from these experiments to publish his On Aerial Navigation in 1809.
