Main components such as the strong FRP fuselage and balsa main and tail wings are pre-assembled. Proven DF45 ducted fan unit produces stable and powerful thrust. 3-servo specifications provide free control of the elevon and swing wing's swept back angle. Brushless motor and fan combine in a one-piece high-efficiency fan unit that produces 270g of thrust (fan unit thrust). One-piece shroud's brushless motor generates 50,000 RPM of pulling power. Battery can be changed simply by removing the canopy (secured with screw). Servo linkages also do not require any special work. 11.1V-700 - 910mAh Li-Po (Lithium Polymer) battery provides the high power.
