WOW, what a great heli!!!

The HK-450TT PRO 3D Torque-Tube Helicopter Kit (Align T-Rex Compat.) is such a great cheap heli, that is exactly similar to the Align Trex 450 Pro, but a very cheap clone version.

After my experience with the HK 450 V.2, I have written a review about it here, if you haven't read it, please do, you might find some interesting info there, I had to go to a better higher spec heli, I liked the 450 size helicopter, and I'm not willing to pay big time in the hobby, not just yet, but as you may know, hobbies are addictive, and you have to spend some money on it, so going for the same size heli, the 450 Pro is the logical successor, it is a bit under 60$, but the quality is worth it.

It has all carbon fiber frame, it comes with all metal parts in the main head, and the tail rotor assembly, it is torque tube, that means no belt, so less vibration, so better stability.

It is a fully redesigned heli, so no parts from the older version the HK 450 V.2 will fit with this heli.

Although this is a much better helicopter, one major draw back I had with this heli is that it is a little tight with the space on it, that I had to put the receiver the Turnigy 9X 2.4GHz 8Ch Receiver (V2) on the outside of the frame using double side tape, but the Hobby King 2.4Ghz Receiver 6Ch V2 was just OK, and it fit inside the frame perfect.

Here are the electronics I used for this heli.

Motor: Turnigy Typhoon 450H 2218H Heli Motor 3450kv (450 class)

Battery: ZIPPY Flightmax 2200mAh 3S1P 20C

ESC: TURNIGY Plush 40amp Speed Controller

Programming Card: TURNIGY BESC Programming Card

Swash Servos: HXT900 9g / 1.6kg / .12sec Micro Servo

Tail Servo: HK15158A Digital BB/Coreless Mini Servo 25g / 2.8kg / 0.07s

I will soon write some reviews about each of these components, so please stay tuned.
