CopterX CX 450SE V2 Edition (eCCPM) represents the state of the art in micro helicopter technology, utilizing the latest design techniques and highest material quality, aluminum parts are anodized in a pleasant blue color. This kit is for the flyers who want uncompromised performance and quality. This SE arrived with 95% Assembled! New CNC carbon frame improve the rigidity and perfect for 3D flying. Changing servo location to CCPM version, new aluminum parts for prompt, precision actions. SSG battery mounting plate connects to main frame. It makes the center of gravity closed to rotor blade, reduced the correction when the heli rotation rolling. Rigid CNC aluminum rotor head for precision and smooth movements. Using Ball and Hiller two systems mixing control. Through simple structure of Ball control system, power-saving of Hiller system and CCPM control, can simultaneously control 3 servo for AILE, EVLE, PIT 3 actions. This CCPM control system is great for 3D flying control and extending life cycle of servos. New streamlined carbon tail rotor blades makes the gyro more efficient. New tail rotor control set, CNC control piece and movable ball link for smooth pitch travel. Providing flybar weight- When normal flying, you can add the weights on flybar paddles for stable flight. When aerobatic flying, you don't need to add the weight, but you can see the flexibility of 3D actions. CNC Metal tail unit and tail holder are using high rigid aluminum, falling resistance. New gear ratio (4.24:1), suitable for the motor with higher KV, provide more safty. Use Aluminum alloy drive pulley and tail drive pulley, high regid and wear resistance. It is efficient to reduce the rotation loss and makes more smooth. All kit use stainless steel linkage ball, wear resistance, anti-oxidization.
