The Ultra Micro eXtreme (UMX) Extra 300 3D takes the idea of a 3D plane you can fly almost anywhere and turns it into a reality. With a flying weight of 33 grams (barely over an ounce), battery and all, it is slow and light enough to fly extreme 3D manoeuvres in spaces no larger than a dining or conference room.
It features an ingenious laser-cut foam airframe, designed by ETOC champ Seth Arnold. The open-frame structure is covered with a micro-thin film and it uses a fraction of the foam material usually used in profile planes of this type.
This super light airframe is reinforced with carbon fibre rods that reduce airframe flexing and twisting to a minimum so you can fly the most aggressive 3D manoeuvres with absolute precision.
Optional Side Force Generators are also included for enhanced aerobatic performance. These razor-thin pieces of foam slide onto the leading edge of the wing and enhance rudder authority in knife-edge flight. They also improve tracking during precision aerobatics too.
The UMX™ Extra 300 3D BNF comes completely assembled with an extremely efficient 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.
For best performance and to maximise your flying fun a DSM2 aircraft transmitter with dual rates and expo is recommended.
