NOW EVEN EASIER TO FLYThe UMX™Radian®ultra-micro motor glider became a class favorite by delivering a unique flying experience you simply can't get from any other model. Due to its traditional motor glider design, the Radian is inherently stable and easy to fly almost anywhere — indoors in gymnasiums and other suitable spaces, and outdoors in most yards, parks and sports fields. The exclusive Spektrum™AS3X®technology of its installed electronics smooths out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you're flying a much larger airplane. E-flite®engineers upgraded this new version to include optional-use SAFE®Select technology, making the Radian even easier for more people to fly in more places. Plus, you can receive real-time battery voltage telemetry with compatible transmitters! It's the perfect next step after learning to fly, a great first glider and an exciting everyday sport model for a wide variety of pilots.UPDATED FOR ULTRA-SMOOTH SOARINGThe ever-popular UMX™Radian®has been updated and upgraded so it's even easier and more fun to fly than before!

This Bind-N-Fly®Basic model arrives factory-assembled and nearly flight-ready right out of the box. Simply install the one-piece wing with a few screws, install a charged battery, bind it to your compatible Spektrum transmitter and fly. Advanced EPS construction provides a lightweight yet durable airframe. The distinctive, gracefully curved polyhedral wing and efficient airfoil deliver outstanding soaring performance and long flight times with or without motor power. The factory-installed power system features a coreless motor, gearbox and an efficient folding propeller. It produces excellent climb performance and extends flight times up to 10-20+ minutes with a mix of power on/off flying using 1S 150-200mAh batteries.
