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 introduced T-REX 450LP ARTF (Almost Ready to Fly). Completed with Align A10 transmitter and newly released MiniGRS flybarless system, just easy to experience the fun fly enjoyment.
The helicopter utilizes DFC rotor, paired with MiniGRS flybarless system optimized for T-REX 450LP flight characteristics. Without any adjustment or tuning, this combo will be provided optimal stability suitable for pilot of all levels.
Equipped with newly digital high voltage servo DS450 and DS455, supports 8.4 high voltage to provide optimal speed and torque performance. Paired with newly RCE-BL45P ESC, supports adjustable 5~8.4V BEC function to highly improve flight performance.
ALIGN A10 is AFHDS (Automatic Frequency Hopping Digital System) 2.4GHz transmitter provided with 10 channels. The stick and holder are designed based on ergonomic bringing much smoother control. Completed function with the mode of helicopter / aircraft / multicopter. Logical and simple control interface, and easy to set up.
With the addition of the brand new A10 transmitter and MiniGRS, the T-REX 450LP ARTF pushes past the performance limitation of flybar helicopter, improving both stability and 3D performance, while maintaining a down to earth price level.

This is a really good kit if you’re looking to step up to something bigger than Micros. This heli pretty easy to get up in the air. You take it out of the box, install the tail, boom, set the transmitter up a little bit, then you should be good to get in the air and the transmitter. The biggest thing you have to change is the throttle curves. Compared to micros this is very stable! It flies and sounds awesome! It’s a great size to lug around, it’s actually significantly smaller than my TB40. The biggest difference between this one, and the Kit they have is this one is 3S, it comes with a transmitter, the mini GRS flight controller, and the blade grips and linkages are plastic. Being 3S this does feel a little underpowered, but not too bad if you’re a sport flyer, you probably won’t even notice it. I noticed it most at lower head speeds where it will bog under our hard collective pull. It gets pretty quick when you crank it up! I do plan on converting this to 6S eventually, in putting a spirit three flight controller on it instead of the mini GRS. The mini GRS is OK, but it leaves something to be desired. I’ve already done my share of upgrades to this machine, there are probably more upgrades for this Heli than any other Heli out there! This guy has been around for a long time! It has a lot of parts that are compatible with a lot of older T-Rex 450 models, and there are lots of aftermarket parts, such as tarot and Garrt for example. One of the biggest upgrades that everybody should make with this thing is get the T-Rex 470 L landing skids. It leans the Heli forward a little bit, and gets the tail rotor away from the ground because the umbrella gears for torque tube strip if you look at them the wrong way! With the 450 landing skids, the tailfin pretty much touches the ground. Very happy with this so far, highly recommended!
Thank you HeliDirect, this bird came in fast and delivered with care, got this heli to surprise and gift to my wife as she begins her flying along side with me. Trex has come along ways on new tech and I’m just Amazed at this new bird compared to my older ones I’m still flying. Anyway the bird itself was easy to finish assembling and it flys Super. This is an Awesome RTF kit.
The last helicopter I flew before the trex 450 was a heli baby from the seventy's the 450 is a very stable machine, in the process of removing the few plastic parts and upgrading to all aluminum over all a great little helicopter
On arrival i unpacked & checked all parts to find the canopy Cracked & Damaged! & the Transmitter was badly Scratched! which i find hard to understand when its bubble rapped & boxed. My conclusion would suggest that i was sent a 2nd hand Transmitter?
I have emailed & there first reply, they said it was cosmetic!! would i like a discount!! Hell No i want them replaced!
The helicopter seems fine but the radio had some minor damage, mostly cosmetic. Customer Service had no trouble repairing and returning it. Been a bit busy so I haven't had an opportunity fly the bird.
The helicopter is great,just don’t think you will go out and fly it with being a beginner,it’s not a beginner helicopter,
Go my issue resolved Thanks HD.
System would not stay bind to transmitter.
When I received the system. I tried to bind the heli and worked on day 1 but all the servos were setup wrong. Called HD no response called Align and I was able to get Tech to help setup the heli and servos correctly. The next day the heli wouldn't bind, tried everything I could find on the web still a no go. Going on 3 weeks and been trying to get this heli replaced/refunded by HeliDirect and been told they are waiting for Align to respone. I just want a replacement from your stock and you can send this heli back to align. Don't understand why I the customer have to wait for Align.
HeliDirect is my go to store for most everything RCHeli. The Trex 450 was initially sold out for Christmas but they put me on their notification list and true to their word, I was notified as soon as it became available.
Shipping was crazy fast and communication awesome.
Thanks HeliDirect
Awesome copter with great design and styling.
I have received my helicopter and am using the simulator to learn to fly it. I am very pleased so far with my helicopter, appears to be a quality product.
Super fast delivery!
Great Heli!
Great delivery time sick an amazing performance helicopter
Unit works well flys easy out of the box.
Good unit for a beginner but would definitely start on a simulator first.
Always great products
goosky s2 is one of the best helis for beginners, its stable , it flies like a much larger heli, it has some weight to it, I've crashed a couple of times and nothing broke. i am so happy i bought this heli, it makes me a better pilot, I've had others, no were near the quality of build. definitely buy a sim to learn the basics. i would buy it again. i love the hobby and i hope this review inspires other people to buy this model...
Every time I have ordered a heli, parts etc it has always been exactly what I ordered and always shows up on time per my choice of shipping. I always go to helidirect first because of the excellent service!
This machine is well built and relatively durable. Out of the box, you put the tail boom on, easy. Add batteries to the A10 transmitter and ready, set, go. The 3s power is plenty at least for me. I can’t do hard 3d stuff anyway. Sport flying and hovering. The radio for an rtf kit in my eyes is really good. Stick tension is good and the switches feel good. The radio itself isn’t too big or little, fits my hands well.
I will add that this helicopter may not be the right choice for someone with no experience flying helicopters. Yes, you can dial it down some but while flys really well there is no self righting in the FBL system.
This is probably an ideal step up after something with some stabilization, still a very solid performer and well worth the money
Very nice easy way to get started in hobby every thing needed is in the box and Very well made looks great
Align T-REX 450LP Dominator RTF (AC) - RH45E32XT
Just perfect. Fast delivery as always. Thank i
Great helicopter but really not good for beginners no safe flight installed
I WAS SENT A BROKEN DAMAGED HELICOPTER AND I'M WAITING TO RECEIVE A BRAND NEW ONE SINCE I'VE ALREADY RETURNED THE BROKEN ONE I WAS SENT TERRIBLE.
Works perfectly. I did alter the pitch curve a little, that was it Love it
Fantastico es bueno que lo vendan programado
What is needed to fly?
Hi Ron
This kits is all you need, but you may need to buy some more extra batteries if you want to have more flights.
