T-REX 450S ARF Combo

• T-REX 450S (eCCPM) helicopter is great for 3D flight and wind resistance, the main frames are made by high strength light aluminum alloy and carbon fiber materail, suitable for 3D Acrobatics and beginners.
• Package- Helicopter completely assembled. The users only need to simply install the power/electronic equipment and make some adjustments. Then enjoy the flight.
• 1mm CNC aluminum alloy main frames features the rigidity and great for 3D flight.
• Aluminum alloy battery mounting plate is fixed to aluminum alloy mounting plate mount for connecting to main frames. Set the battery here and make the center of gravity close to the rotor blade sides for reducing the trim when the heli rolling.
• CNC Main rotor housing is made by hard aluminum alloy material.
• 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 design for Tail pitch assembly, upgrade to ball control slider bushing with dual bearing, add collars to ball links for reducing the gaps, maks the change of pitch travel more smooth.
• Using new design on tail rudder control rod and control guide for smooth control, the design is same as TREX 600.
• 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.
• New gear ratio(4.24:1), suitable for the motor with higher KV, provide more safty.
• Using super strength drive belt and tail drive gear, features wear resistant to reduce power loss.
• All kit use stainless steel linkage ball, wear resistance, anti-oxidization.
• Tail rotor hub made of stainless steel, very rigid.
• Use 33pcs 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!
