Features:

This kit is for the fliers who would like to want the excellent performance and quality. This kit is 80% pre-assembled.
* Rigid CNC aluminum rotor head for precision and smooth movements.
* Using new Main rotor holder with thrust bearing and 5mm Feathering shaft, features smooth rotation and stability under high rotation speed.
* 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 tail rotor control set with dual bearing, features CNC control piece and smooth structure design, get 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? need to add the weight, but you can see the flexibility of 3D actions.
* CNC tail pulley assembly and tail holder are using high rigid aluminum alloy, features wear resistant and 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.
* Tail rotor hub made of stainless steel, very rigid.
* Use 31pcs precision bearing.
* Great stable and sensitive mixing lever design! Can disply the great stability and precision for 3D flight.
* Adjustable pitch system, hold rotation system, tail rotor drive belt system! It is a work of great originality for helicopter!
