The E-flite UMX Radian Bind-N-Fly Basic Electric Airplane has been updated and upgraded with exclusive Spektrum optional-use SAFE Select technology so it's easier and more fun to fly than before! The ultra-micro motor glider now provides real-time battery voltage telemetry to compatible transmitters. 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. Because of its ultra-micro size, the UMX Radian can be flown indoors in gymnasiums and other suitable spaces, or outdoors pretty much anywhere — in most yards, parks, sports fields and beyond! If you learned to fly with a HobbyZone Sport Cub S, you can use the same transmitter, battery and charger and make the Radian an economical next step. It's an ideal first glider or everyday sport model for low-time to experienced pilots interested in an easy to fly, ultra-micro class motor glider that delivers a unique flying experience!
