Swing the wings out for excellent low speed stability, or fly with the wings swept back for high speed performance.Lightweight and simple structure uses one servo to control the swing angle of the main wing.Main components such as the strong FRP fuselage, balsa main and tail wings are pre-built in this factory-assembled kit.Mixing radio system realizes precise control inputs and angle of the swing-wing.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 high-efficiency one-piece fan unit that produces 270g of thrust (fan unit thrust).One-piece shroud's brushless motor generates 50,000 RPM of pulling power.11.1V-700 - 910mAh Li-Po (Lithium Polymer) battery provides the power for potent jet flight. (No.ORI60037 recommended)Removable canopy enables easy access for changing battery and linkages or other maintenance.Balsa rib tail wing is pre-covered in film. Simply fix to the fuselage to complete. 4-channel specifications for elevon, throttle and swing-wing control.
