The T-REX 450 has been the ideal choice for entry level R/C helicopters. To cater to the beginner enthusiasts and solve the problem of assembly and adjustment, Align introduces the T-REX 450LP ARTF (Almost Ready to Fly). Completed with an Align A10 transmitter and newly released MiniGRS flybarless system, you are now able to experience RC Helicopter flight.

The helicopter utilizes a DFC rotor head, paired with the MiniGRS flybarless system optimized for the T-REX 450LP flight characteristics. Without any adjustment or tuning, this RC Helicopter combo from Align provides optimal stability suitable for pilots of all levels.

Equipped with new digital high voltage (HV) servos DS450 and DS455, supporting 8.4 volts to provide optimal speed and torque performance. Paired with the new RCE-BL45P ESC, with adjustable 5~8.4V BEC function to profoundly improve flight performance.

ALIGN A10 is AFHDS (Automatic Frequency Hopping Digital System) is a 10 channel 2.4GHz transmitter. The A10 is an ergonomic design to provide a comfortable feel with smoother control. The Align A10 is a full function transmitter offering helicopter/aircraft /multicopter modes. A simple control interface allows for easy setup.

With the addition of the brand new A10 transmitter and MiniGRS, the T-REX 450LP ARTF pushes past the performance limitation of a flybar helicopter, improving both stability and 3D performance, at a down to earth price level.


Equipped with the DFC flybarless head designed for extremely low CG (Center of Gravity) to minimize wind resistance while providing an enhanced direct control feel. Included as standard features are the new main rotor head block and spindle design. New designed 325mm 3D main rotor blades are stable and agile resulting in improved flight performance for the beginner or 3D pilot.


Align has over 25 years of experience with motor core technical knowledge. Based on 3s 11.1V the 460MX (3200KV) motor designed explicitly for the T-REX 450L Dominator, featuring superior efficiency, high power output, extreme torque, low current, and low operating temperature. The 460MX motor shares the same extraordinary engineering design features as the 850MX Dominator motor.


Three programmable throttle speed settings for quick throttle response control. Adjustable BEC output voltage (5~8.5V), auto power detection system suitable for 2S~6S LiPo battery, a continues 3A current rating, a burst rating of 6A, continuous current 50A and a surge current 60A for 15 seconds.


Carbon main frames utilize composite integration technology to embed the battery mounting rails directly into the frames. This high-end manufacturing process allows for the intelligent use of open space in the frame body for a more rigid frame structure to improve flight performance. The T-REX 450L cleverly expands on the core concepts of the T-REX 450 Pro design to continue our design excellence.

1. Automatic Frequency Hopping Digital System, AFHDS is a highly developed remote signal transmission system, providing long range, minimizing interference, with lower power consumption.
2. The frequency range of the system is 2.408 ~ 2.475 GHz. The waveband is separated from 160 independent frequencies. The transmitter uses 16 different frequency and 160 different frequency hopping algorithms. Each time the transmitter is powered on a different frequency hopping scheme is used allowing the transmitter to avoid interference of the transmission signal.
3. Each transmitter has unique ID code when binding to the receiver, the receiver saves this unique ID code and only accepts a signal transmitted by the saved ID code transmitter. This process avoids receiving another transmitter signals and significantly enhance the anti-interference ability and security.


A roll style slider is used to scroll through menu options providing a quick setup. 20 models memory with either Chinese or English interface, three aircraft options (helicopter/airplane/multicopter), Modes 1-4 available with optional direction output, set buzzer warnings, and supported firmware upgrade.

Up to four electronic timmers. Ergonomic design for comfortable feel and smoother control. The transmitter case is matte black with spined red control sticks to give a unique, and stunning look,
This system uses a high-quality gain antenna covering the entire available bandwidth. With high sensitivity receiver, the system can effectively avoid long-distance transmission signal interference.
Adopted low power rated electronics and a highly sensitive receiver chip. The transmitter frequency module uses an intermittent transmission signal to reduce transmission power and increase battery life dramatically. Provided charging port, simulator support, and firmware update ability.

A6B is a bi-directional receiver for fixed wing/gliders/helicopter, adopts AFHDS2A (Automatic Frequency Hopping Digital System Second Generation) and omnidirectional antenna which has a powerful anti-interference function.
