E-flite Ultra Micro eXtreme Extra 300

Oct 24, 2010 No Comments by



























The Ultra Micro eXtreme (UMX™) Extra 300 3D BNF makes the dream of a 3D plane you can fly almost anywhere indoors a reality. With a flying weight of barely over an ounce (about 33 grams), battery and all, it is slow and light enough to fly extreme 3D maneuvers in spaces no larger than a dining or conference room.


Its ingenious laser-cut foam airframe, designed by ETOC champ Seth Arnold, uses a fraction of the foam material typically used in profile planes of this type and is covered with micro-thin film. Carbon fiber reinforcement rods keep flexing and twisting to a minimum so you can fly the most aggressive 3D maneuvers with absolute precision.

Best of all, it’s a Bind-N-Fly® aircraft so you can have it up and flying in the time it takes to charge the battery and bind it to your DSM2™ aircraft transmitter.*

*A DSM2 aircraft transmitter with adjustable dual rates and exponential is recommended.
