The E-flite Eratix 3D Flat Foamy 450mm offers the aggressive aerobatic plus smooth sport and slow-flying performance of flat foam models - without all the hassles of buying components for and building one! It arrives fully factory assembled and ready to bind to your compatible Spektrum transmitter, allowing you to fly in almost no time. Inspired by the UMX Extra 300 and Yak 54 flat foamy models, its laser-cut and composite reinforced airframe makes it light enough to fly extreme 3D maneuvers indoors in spaces no larger than a living or conference room, or almost anywhere outdoors. The factory-installed brushless outrunner motor with a prop saver is compatible with popular 2S 280-350mAh batteries. It's also equipped with expertly tuned AS3X and SAFE Select technologies, plus it provides real-time battery voltage and other telemetry information to compatible transmitters. This makes it a versatile addition to the hangar for a wide variety of intermediate to experienced pilots!
