216002 - X3 Basic Kit (with CNC Tail Blade grips) ● The X3 Continues the X series of high-strength design with its 6mm main shaft 5mm spindle shaft, 4mm horizontal tail shaft and M2.5 screws, supports 315 ~ 360mm main rotor blades. These specifications exceed that of most standard 450 sized helicopters making it suited to the high loads of today’s extreme 3D flying. ● Head with integrated phase type Vanda design. Its’ all bearing design yields low drag and very smooth operation. Ball joint arms allow for convenient user adjustment. ● Integrated tail gearbox design developed on the X7 and X4. Double tail pitch control structure distributes forces more evenly on the tail shaft. Dual thrust bearing design leads to an exceptional smooth tail. ● Unilateral plate body design is very simple, ensuring accurate main shaft bearing installation, compact structure. 6mm thick main gear with a helical design give a large surface area for powerful motors (2221 ~ 2520) yet with exceptional quietness in use. Tail drive gear uses the same design as the X7 with a tail shaft direct drive bevel gear, the crown gear is also designed with a metal plate, to ensure a true and smooth running gear. ● Quick release battery rail mounting allows for simple and quick battery replacement. The battery is built into the body of the main frames which provides exceptional crash protection for the battery in a crash. ● The tail rotor servo is installed inside the frames and is compatible mini and micro servos.
