Video Overview


Overview

The Ultra Micro eXtreme (UMX) Extra 300 3D makes the dream of a 3D plane you can fly almost anywhere a reality. With a flying weight of barely over an ounce (just 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, makes it all possible.

The structure uses a fraction of the foam material usually used in profile planes of this type and is covered with micro-thin film. The airframe is reinforced with carbon fiber rods that keep flexing and twisting to a minimum so you can fly the most aggressive 3D maneuvers with absolute precision. Optional Side Force Generators are also included. These razor-thin pieces of foam slide onto the leading edge of the wing and enhance rudder authority in knife-edge flight. They improve tracking during precision aerobatics too.

The UMX™ Extra 300 3D BNF comes completely assembled with a punchy 8.5mm coreless brushed motor and Spektrum™ AR6400L Ultra Micro DSM2 Receiver/ESC installed. Built-in long-throw servos on the AR6400L drive the elevator and rudder while two independent Spektrum AS2000L long-throw ultra micro servos drive the ailerons. A 1S 3.7V 150mAh Li-Po battery and DC Li-Po charger are also included. For best performance, a DSM2 aircraft transmitter with dual rates and expo is recommended.
