TREX550 1


Manufactured with durable lightweight fiber material, 
and utilizing an engineered aerodynamic design, 
the Align Advanced Lightweight Canopy forms a 
protective shield for the entire machine. 
The Align T-Rex 550X is 200g lighter than our pervious model.


Landing skid is tilted 5 degree forward which improves crashworthiness.


The 550EFL Flybarless Rotor Head System utilizes extreme low CG design 
to effectively reduce resistance during 3D maneuvers while increasing flight 
responsiveness and precision. In addition, the high quality of the helicopter 
design is accented with red anodized and stainless color precision machined metal parts. 


Align Advanced Metal Swashplate firmly connects to rotor grips preventing rotor head 
disengagement during intense flight. Two linkage ball mounting holes provided to 
improve control of system movement. A resolution hole or larger movement reaction 
hole can be selected based on your flying preference or style.


Brand new 730MX motor is especially designed for power upgraded T-REX 550X, 
normally found in 700 class high spec helicopter, that enthusiasts can clearly feel 
the dramatic increase in power and torque, while taking advantage of its higher efficiency, 
lower current and temperature benefits. Features with high torque, high efficiency, stable and quiet.


The high-end Microbeast PLUS 6-axis gyro with 32-bit high-speed processor is much precise 
and superior in programming and computing allow for significant handling performance and 
delicate response. In addition, the Microbeast PLUS gyro is vibration-reducing improvement 
and strongly reduce the effects of the vibration to flying performance.


32-bit fast-speed processor.
High quality MOSFET.
Adjustable BEC function, supply power to receiver and servos.
Superior governor feature.
Support 730MX Brushless Motor, Extreme 3D Flight.
Support USB interface to PC for firmware updating.


Designed specifically for helicopters, utilizing a brushless motor for fast speed, 
high torque, and super efficient reaction time, allowing the Align 700X 
to perform faster with precision. The brand new DS820 high voltage brushless servo 
is equipped with a new CNC machined aluminum case. This new aluminum case exhibits 
top of the line servo aesthetics while providing a heat sink function for the best protection of the servo.


3K Main frame features; embedded battery mounting rails, integrated magazine structure, 
and a latch design which provides great protection for the battery while providing 
a convenient way for mounting. This unique use of open spaces within 
the frame creates a rigid frame and is aesthetically pleasing.


Integration of CNC Aluminum alloy and POM Polyacetal which can lower friction between 
the linkage ball and the Metal Anti Rotation Bracket. In addition, this new design increases 
the efficiencies and accuracy of the servos.


Carbon Fiber Tail Control Rod improves the helicopter tail control. 


Durable and Precise! Manufactured with stronger material, the Torque Tube Front Drive Gear 
is more durable and precise. The stronger material reduces the probability of gear striping during flight 
or damaging the gear as a result of a crash.The newly designed dual point supported tail pitch assembly 
delivers slop free performance while improving rudder resolution and precision.
