EXI MB450 Aluminum Alloy ARF Electric Mini Heli w/ 325 Carbon Fiber Blade
(PART COMPATIBLE WITH TREX450)

(Canopy may need some modification to fit)

This kit is for the flyers who want uncompromised performance and quality. This product arrived with 95% pre-assembled.

• New CNC fiber frame only 1.2 mm, improve the rigidity and perfect for 3D flying.
  
• CCPM version, new aluminum parts for prompt, precision actions.
  
• New longer 3K battery mounting plate connects to main frame. It makes the center of gravity closed to rotor blade, and can adjust the center of gravity according to the weight of battery, it reduces the correction when the heli rolling.
  

• Rigid CNC aluminum rotor head for precision and smooth movements.
  
• Tail rotor hub made of stainless steel, very rigid.
  
• Use 35pcs precision bearing.
  
• Great stable and sensitive mixing lever design! Can disply the great stability and precision for 3D flight.
  
• Special adjustable pitch system, hold rotation system, tail rotor drive belt system! It is a work of great originality for helicopter!

Key Features

Using new Main rotor holder with thrust bearing and 4mm 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 c.g. amended tail blades feature streamlined and quick, make the gyro more efficient.
  
• 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¡¯t 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.
  
• Using new high strength ball links and stainless steel linkage balls on the whole unit, feature wear resistance, anti-oxidization.
  

  

  

  

  

  The MB 450 uses a combination of tough, lightweight aluminum and updated composite parts and is designed and equipped to be capable of the most extreme 3D maneuvers . And since it's 95% assembled, you can have it flying in just a few hours.
