The E-flite UMX Radian is a powered sailplane that packs all the simple fun of the larger ParkZone Radian into a much smaller package that is an absolute pleasure to fly. AS3X technology gives pilots the feeling of flying a much larger glider, especially outdoors, as it offsets the effects of wind and turbulence. The distinctive cambered wing delivers excellent lift and impressive glide ratio with simple 3-channel control. The lightweight brush drive system requires only a single-cell Li-Po battery to provide excellent takeoff performance and long flight times. Plus, the one-piece wing is easy to remove and store in the box with a handle, so you can soar through the clouds in complete comfort.
