    The NEW T-REX 550X is definitely a significant leap forward in performance, enhanced by increased power, the integration of numerous innovative design changes, and lightweight improvements. The T-REX 550X performance is outstanding!

    The brand new FL Flybarless Rotor Head System utilizes an extremely low CG design, reducing resistance during 3D maneuvers while increasing flight responsiveness and precision. A progressive design adds a gloss silver and red anodizing appearance which continue our quality development based on our 700 class helicopter. The T-REX 550X main frame utilizes composite material integration technology on carbon side frame plates, including the addition of battery mounting side rails, and a top motor mount design. In addition, the T-REX 550X's lightweight design is 200~250g (Combo250g/Super Combo 200g) lighter than our pervious model, this effectively increase the power and improves flight time.

    The T-REX 550X utilizes the powerful 730MX (960KV) motor and our RCE-BL100A Brushless ESC which both are highly efficient providing superior power, improving the performance of the 6S power system. The NEW DS820/DS825 high voltage brushless servos are extremely efficient and out perform other servos in this class. To protect these servos the new high-end CNC aluminum case function as a heat sink allowing the servos to operate at a lower temperature.

    With improved performance and increased power, as well as included top of the line electronic equipment. The new T-REX 550 X will arouse your enthusiasm and devotion to the T-REX Family.

    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.


    The matting carbon tail boom using 3K carbon fiber and aluminum imbedded technology, features light weight and high strength.


    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.

     Comes with this new T-Rex 550X is the new servos from Align with very light plastic case and CNC metal case. Designed specifically for helicopters,utilizes brushless motor for fast speed, high torque and super efficiency reaction, allowing helicopter to perform with faster and higher precision. Brand new high voltage brushless servo equipped new CNC machined aluminum case, not only exhibited top of the line servo aesthetics, but also combine heat sink function and best protection for the servo. Utilizes brushless motor design for fast speed, high efficiency. And with the absence of brush wear, the longevity of servo is greatly increased. Supports 8.4v high voltage to provide optimal speed and torque performance of the brushless servo.
