Understanding the technology and its safe use EducationFor some pilots, the idea of tuning a combustion engine is enough to keep them away from the flying field. Electric-powered aircraft provide these pilots a means to enjoy model aviation without the fuss of a “traditional” engine. LiPo (Lithium-Polymer) batteries are a popular means for powering our electric models. When used properly, these batteries provide convenient, reliable, renewable, and relatively inexpensive power. 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. In this four-part series, we’ll teach you all about this popular power source.
