With no Hi-start or cumbersome launch system to worry about, its built-in high-power electric motor system and lightweight construction delivers a soaring experience that's hassle-free. The distinctive, 2-meter span elliptical polyhedral wing allows it to efficiently capture lift and deliver excellent maneuverability with the simplicity of three-channel control. The 480-class brushless motor not only gives the Radian glider outstanding climb performance, its efficiency with the required battery will allow you to climb back up to altitude to chase those thermals multiple times on a single charge. The original Park Zone Radian airplane introduced many to the elegant simplicity of thermal soaring. Made of durable Z-foam material and equipped with a smooth, efficient brushless power system, it gave RC pilots a level of enjoyment that's made flying with a glider the perfect activity even for grabbing a quick flight. This E-Flite Radian motor glider carries on the design with improvements to the airframe for an even easier soaring experience.
