EXI MA450 Aluminum Alloy ARF Electric Mini Heli w/ 325 Carbon
Fiber Blade
(Assembled with TREX450 HOP
UPS)
This MA 450 is for the flyers who want uncompromised performance
and quality. This product arrived with 95% pre-assembled. It 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 this kit is
95% assembled, you can have it flying in just a few hours.
Features
-
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!
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 safety.
Using new high strength ball links and stainless steel linkage
balls on the whole unit, feature wear resistance, anti-oxidization.
