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.


Included is the A10 Transmitter with Automatic Frequency Hopping Digital System, AFHDS is a highly developed remote signal transmission system, providing long range, minimizing interference, with lower power consumption.


Easly charge the T-REX 450LP ARTF battery with the included RCC-3SX Align Balance Charger for 2S 7.4V and 3S 11.1V lipo batteries.


Included is an Align 3S 11.1V Lipo battery. When ordering your T-REX 450LP ARTF we suggest ordering an additional battery.

The T-REX 450LP ARTF assembly is simple and quick by following the instructional video. You will be ready to fly before the battery is full charged.
