This is the Align T-REX 450LP "ARTF" Electric Helicopter. Pilots looking for an excellent quality and ready-to-go package in a 450 class helicopter, look no further. In a matter of about 20-30 minutes you can be up in the air with the T-Rex 450LP. Built on the successful 450L platform, the LP is an strong and proven design with incredible presence in the sky allowing for excellent visuals and stable and steady flight. As pilots progress in skill, the 450LP is both capable and upgradeable, allowing for an even longer timespan of ownership. 

Packaged with the 450LP is the Align A10 2.4Ghz Radio Controller, which sports 10 channes, helicopter, airplane, and drone programming, all in a compact and lightweight design. The 2.4GHz module utilizes automatic frequency hopping digital system (AFHDS), offering robust signal strength even at extreme distances. Programming the radio is a breeze thanks to the scroll wheel found on the right side of the radio. Up to 20 models can be stored on the A10 radio system. 

The electronics package is no different than found in the higher end 450 Align Kits. Align 460MX Brushless Motor, BL45P ESC, DS450 Cyclic Servos, & a DS455 Tail Servo are outfitted providing the pilot with consistent day to day reliability that is critical when learning to fly, or just taking a break through the day and enjoying helicopter flight.  The 3s Battery is mounted to a tray which is a quick and easy way to swap packs out to ensure that you are focusing on flying, and not strapping down batteries to a frame or a tray wasting precious time. 

The Align Mini GRS Flybarless Gyro System offers a simplistic approach to flybarless gyros, and is directly compatible with the Align A10 radio system. This gyro can be utilized in the T-Rex 250, 450, 470, and 500 models, allowing for flexible use of the Gyro in the future if the pilot so chooses. Additionally, this gyro system supports Futaba S-FHSS with built-in capabilities, as well as an ANT port for Spektrum DSM X Sattelites. 

NOTE: This helicopter is described as "ARTF" because the tail boom and torque tube assembly are not installed on the model from the factory. This process is outlined in the manual and should only take about 15 minutes to complete. Other than this, the model includes EVERYTHING in the box to fly, with the exception of "AA" batteries for the radio. 



  • Equipped with the DFC flybarless head assembly, with extremely low CG design to minimize wind resistance while providing more direct control feel. In addition, the main rotor head block and spindle design have been incorporated as standard feature.
  • Carbon side frame plates utilized composite material integration technology, featuring integrated battery mounting rails. The clever use of open spaces within the frame resulting in a structure that is both rigid and aesthetically pleasing. In addition, the T-Rex 450LP cleverly expands on the core concepts of T-Rex 450 Pro designs, to carry on the heritage of its mature design of excellence.
  • Designed with direct servo CCPM control, and a single piece main bearing block with integrated servo mounts similar to that of T-Rex 700E DFC, for simplified servo installation and clean aesthetics.
  • Included 460MX (3200KV) motor is tailor made 3S voltage and the T-Rex 450LP, featuring superior efficiency, high power output, extreme torque, and low current, low temperature.
  • Includes RCE-BL45P electronic speed controller,capable of 2S-6S lipos, with switching BEC featuring variable voltage adjustment between 5V-8.4V.
  • Frame reinforcement plates were added to effectively increase frame rigidity and increase anti-torsion ability. Classic red anodizing increases overall aesthetics of the helicopter.
  • Battery mounting plate with battery latching design, along with integrated mounting rails in side frames to simplify battery installs while protecting them.
  • Swash anti-rotation guide with embedded anti-wear material, effectively minimize the wear between swashplate long ball and guide.
  • Vertical rudder servo mount design for closer CG, increasing the sportiness of 3D flights.
  • Added tailboom support bridge design to increase the rigidity of the overall tailboom/support assembly.
  • Tail is made from competitive material using special embedded carbon technology for enhanced structural strength and excellent visibility.
  • Tail blade grips with thrust bearing design, dramatically increase rudder precision and tail locking effectiveness, while increasing the longevity of bearings.
  • Dual point supported tail control assembly for slop free tail, improving rudder resolution and control precision.

Align T-Rex 450LP Dominator RTF Electric Helicopter
First, Amain was great and as helpful as possible. Heli was shipped fast and arrived well. BEFORE YOU HOVER....Turn on A-10 radio, go to EACH and EVERY window in menue and take a picture or write down EVERY value. WHY? This hell comes fully adjusted and ready to hover in novice mode. Apparently, this is NOT the same as "factory setting" in the menue. Mine hovered OK initially, but as an experienced heli pilot I wanted to make some minor adjustments. I did, but in the process I made some "tweaks" that I didn't like and decided to go back to "factory Settings" per the menue instructions and start over. When I next tried to hover the heli, it was totally uncontrollable! I tried this many times to no change. Even the throttle hold switch did not work!
After 2 bad tipovers on the ground, more than $100 in parts, going through 2 sets of TX batteries I never did find the right combination of settings that were on my radio when I received it!
I also had a problem with the wheel selector on the A-10 TX. It was very hard to turn and after it was pressed to enter a setting it would stay stuck in that position until I gently pried it out with a screw driver. A real pain when you are trying to program!!

I built and flew an "old" Align 450 with flyer and that kit seemed much more robust than this one. It was certainly much easier to work on! Since I never got past an initial hover with this one I cannot attest to its flying capabilities. I WILL say stay clear of the A-10 radio that comes with it.

This is NOT an Amain issue. It is an Align issue!!

Align T-Rex 450LP Dominator RTF Electric Helicopter
Nice it is already built but the radio and receiver in it is not so good it's transmitting PWM I think I did not find S-BUSS you have to set some tweaks to dual rates N Expo, Pitch Curves are set at 0% at 0, at Low throttle At 60%/2, 60%/3,and 60% at High. Adjust the radio to your liking and some tweaks to Radio and the receiver/gyro if needed I changed settings to stop any floating around at a hover it doe's well for a practice flyer great tail rudder lock just cyclic pitch and roll you can do that on the receiver it has pitch roll and yaw screw make small adjustments back and forth with the provided black hard plastic screw driver so you do not strip screw in the receiver, nice to pull it out ball assembled and do flight check and fly. The only reason it got a 5 is this is a very nice align helicopter and already assembled, do not like the receiver to much, but it works with this little 450lP dominator with torque tube tail drive, Get extra boom and front and rear torque tube gears.

Align T-Rex 450LP Dominator RTF Electric Helicopter
So far I am very happy with this RTF. Havent got much time to fly yet.
Very easy to finish assembly. No problems binding on first turn on. The transmitter is a little cheaply made but works perfectly.

Align T-Rex 450LP Dominator RTF Electric Helicopter
Very high quality product , but that's to be expected from Align . Zero issues from assembly to set up . Perfect heli in my opinion . Great size not too small like the 200-300 class you'll out grow . Not too large where replacement parts and upgrades can be expensive . It's one of the most popular helis for a reason . If it's in stock definitely grab one , they tend to sell out fast . Lucky to find it when I did

Align T-Rex 450LP Dominator RTF Electric Helicopter
Rtf? Radio does not work. Called to get RMA. Had to call enterprise hobby. Then told they would not take care of it. Told to call amain .. Finally got RMA. Sent my package thru ups. Then got another email to send it to another supplier after I had already sent it off. So have not been able to fly. So much for rtf.

More comments after I get to fly

Align T-Rex 450LP Dominator RTF Electric Helicopter
Overpriced Piece of junk. Parts break and fall apart when you try to take off everytime. Brand New and I already spent hundreds on parts to try to fix it and didn't even take off yet. I'll never buy align helicopters again.
