The ever-popular UMX Radian has been updated and upgraded so it's even easier and more fun to fly than before! The ultra-micro motor glider now includes exclusive Spektrum optional-use SAFE Select technology and provides real-time battery voltage telemetry to compatible transmitters. This Bind-N-FlyBasic 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!
Bind-N-Fly convenience
This Bind-N-Fly (BNF) Basic model comes out of the box with the power system, servos and a Spektrum 2.4GHz receiver installed, so all you need to do is bind the receiver to a compatible Spektrum DSMX/DSM2 equipped transmitter (sold separately), install a charged battery (sold separately) and fly!
Exclusive technologies
This UMX Radian is equipped with exclusive Spektrum AS3X (Artificial Stabilization – 3-aXis) and SAFE (Sensor Assisted Flight Envelope) Select technologies. AS3X works behind the scenes to smooth 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. Optional-use SAFE Select offers pitch and bank angle limits along with automatic self-leveling that can be turned on and off at the flip of a switch, making it easy to fly for low-time and experienced pilots alike.
Telemetry capable
The UMX Radian is equipped with a control unit/flight controller that includes two servos plus an ESC and Spektrum receiver that provides real-time flight battery voltage telemetry to compatible Spektrum AirWare equipped transmitters (including the DX6e and 8e, DX6 G2/G3 and 8 G2, the DX9, NX6, 8 and 10, the iX12, iX20 and others) while you fly.
Long flight times
The factory-installed power system features a coreless motor, gearbox and an efficient folding propeller that delivers excellent climb performance and long flight times up to 10-20+ minutes with a mix of power on/off flying when using 1S 150–200mAh batteries.
Factory-assembled
The UMX Radian arrives factory-assembled and ready to fly 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 you're ready to fly!
