All-New Align T-REX 700X is specially designed for extreme 3D flight addicts.

The advanced engineered narrow body design efficiently decreases gear abrasion, machine deformation, increases power, and extends flying durability. The unique Split-Type Main Frame design, made of composite material side plates, is engineered using our proprietary embedding technology, which strengthens the entire structure and provides better accessibility for servicing the T-REX 700X. This extraordinary design includes a progressive lightweight landing skid making the T-REX 700X the leader in the 700 class. The Align T-Rex 700X is 400g (0.882lbs) lighter than our pervious model, this can effectively increase your flight time. The brand new 700EFL Flybarless Rotor Head System utilizes an extremely low CG design which reduces resistance during 3D maneuvers while increasing flight responsiveness and precision.

The T-REX 700X is equipped with the new 850MX motor which is highly efficient with superior power, excellent torque, low current draw, and is the most advanced motor approved by World RC Champions. The new designed motor cooling mount plate can reduce the motor operating temperature up to 20°C (68°F). The helicopter’s high quality design is accented with precision machined red and silver metal parts. The brand new RCE-BL130A brushless ESC supplies extreme power. The ESC includes a superior governor and BEC which allows you to set 5V-8V (Step: 0.1V). The NEW DS820M/DS825M high voltage brushless servos are more 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.

We developed the ultimate perfect 700 class helicopter which is stronger, yet lightweight, and built with precision manufactured high-quality parts. The T-REX 700X, King of the Sky, has arrived! What are you waiting for? The innovative design and high-end electronics will give you an adrenaline rush!


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.


Landing skid is tilted 5 degree forward which improves crashworthiness.


Engineered Narrow Body Design efficiently decreases gear abrasion and machine deformation. The Align T-Rex 700X newly designed narrow body is more powerful and has longer flying durability.


The 700EFL 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.


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.


Our new 850MX motor inherited features from the previous 800MX such as high efficiency, superior power, excellent torque, low current draw, and a low operating temperature. The 850MX is capable of maintaining a more consistent torque and head speed through continuous 3D maneuvers. This is a particularly designed for 3D flights.


The CNC Plate is designed to strengthen the Align 700X frame while efficiently acting as a heat sink to efficiently dissipate motor heat. (This can lower motor temperature up to 20 degrees Celsius during flight)


New RCE-BL130A Brushless ESC: 32-bit fast-speed processor. High quality MOSFET. Adjustable BEC function, supply power to receiver and servos. Superior governor feature.


3K Main frame features; embedded battery mounting rails, integrated magazine structure, and a latch design. The CNC Aluminum Battery Mount provides great protection for the battery while providing a convenient way for mounting.


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 DS820M 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.


Composite material side plates engineered by exclusive embedding technology, which strengthens the entire structure and eases serviceability.


Innovative Servo Embedded Mount. Servo mount manufactured using the latest composite material technology to integrate carbon fiber and POM (polyacetal), which efficiently strengthen its protective function and reduces abrasion of signal wires.


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.


Highly enhance structural strength, effectively increase the torsional capability.


Brand new matting carbon tailboom using 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. A simple enhanced Multiple-bearing design allows smooth and accurate movement. Take control of your T-Rex 700X just the way you like it!
