HK-450TT PRO V2 Flybarless 3D Torque-Tube Helicopter Kit (Align T-Rex Compat.) (USA Warehouse)
Our most popular HK450PRO helicopter kit now offered in a flybarless torque tube version!
HK-450TT PRO V2 Flybarless CCPM 3D Electric Helicopter Kit (Align T-rex Compatible). Modeled on the famous and proven Align T-Rex 450PRO V2 Flybarless helicopter kit. Take a close look at the head and tail of this awesome machine. It's ultra light, yet rigid design is strong enough for even the most skitzophrenic of 3D helicopter pilots!
When comparing helicopters, carefully look at the tail and head unit. Our 450PRO V2 Flybarless is FULLY 'PRO' and does not use parts from previous models.
*Now featuring an upgraded metal tail slider and tail slider control arm!
Features: • Newly designed low wind resistance flybarless rotor head assembly with reduced distance between rotor head and frame, effectively lowering the CG for better 3D performance. • Single piece integrated design of main bearing block and servo mount. • Single piece integrated design of anti-rotation guide and gyro mount. • Single piece integrated landing gear. • High precision flybarless head system. • Newly designed high resolution swashplate. • Single piece battery mount with integrated canopy mount designed to bring CG closer to disk plane. • Highly rigid frame with single piece carbon side and bottom plates. • Highly efficient shaft driven tail design. • Weighted tail rotor blade grips to repel centripetal forces. • Straight-up in-frame alloy rudder servo mount for improved geometry and better CG. • Newly designed aerodynamic canopy. • Newly designed high strength main blade grips. • Upgraded metal tail slider and tail slider control arm.
FBL head is smaller, less complex, has fewer parts that could fail, causes less wind resistence, and easier to fix. With a good FBL gyro, I can think of no benefit to sticking with flybar. I don't even think the name brand companies (Align, Gaui, etc) offer new models with flybars anymore.
hello, I am sort of a noob when it comes to helis. I have used a simulator and have a coax heli. I am ready to move up to a fp or cp heli but was wondering what are the pros and cons of a flybarless head? thanks!

Align main/auto/oneway $20.........so for $208 CAD plus batteries you have a pretty cool 450 helicopter. dont forget you need some tool, a charger, thread locker and a radio.
Be prepared: 1. to replace every gear with either an align or tarot (cheaper and just as good as aligh) parts. 2. to replace most of, if not all, of the tail assembly with align or tarot parts. 3. to replace the entire head with align or tarot parts. 4. to replace every bearing with anything else that fits.
I have built 4 of these, and quality and fit has been all over the place. on 3 of the 4, I replaced all of the above. On the 4th, everything but the tail. It's still a deal if you get your replacement (tarot) parts from somepleace like infinity hobby. About $110 total gets you a complete tarot 450 pro v2 DFC. Not a bad deal at all.
From my experience, the Tarot helis are much higher quality. The first and last order I placed with value hobby took 3 weeks to get, and I had to email them a couple of times. The heli that they have listed doesn't look like any Tarot heli that I've seen. The good Tarot 450 FBL costs about 150 even from china.
Motor: HeliDrive SK3 or one of the Turnigy ones. ESC: 40-50A, the Turnigy Plush's are good. Servos: HXT900s or metal geared Corona ones. Setup should be fine with a 2200 mAH 3S for sport flying and then good for 3D once you master that. Have fun and fly safe!
Really new into these heli's
been playing with a lot of micro helis and sorta want to move into bigger and outdoor helis
not sure if this is a good idea but what would be required to buy also when i get one of these kits?
like i see the required section, but is there any suggested motors, servos, batteries, etc...? (do i need to get my own radio also?)
You will need a motor, 3 cyclic servos and 1 tail servo, batteries, ESC and you will need your transmitter and receiver. If you have never flown a collective pitch helicopter it would be smart to get a simulator, that way your learning curve will be easier and cheaper. I have not been in helicopters very long but I started with a trex 450 v2 clone kit of about 37 dollars and got everything as cheap as possible. Many would tell you to go for the big things right off the bat but I dont regret how
This HobbyKing 450 Pro helicopter is outstanding!
First impressions were great, it was shipped quickly in a very small box, the build went very smooth with little to no issues (Not a single stripped or stuck screw)! However, there are a few minor things I would recommend replacing with other brand parts such as Align...
Almost essential to replace:
Torque Tube (the stock torque drive shaft is very heavy, the Align version is 1/4 the weight)
Front Umbrella drive gear (it chipped in hover mid flight during maiden flight, almost crashed but luckily I was only 5 feet off the ground)
Not essential but helps in performance / etc:
Replacing the stock tail boom with a carbon fiber boom ($4.00) (half the weight, helps with balance)
Longer carbon tail fin for easier grass take-offs
Anyways, I fitted this with a Tarot FBL system, 9g servos, scorpion motor and Hobbywing esc. I am running this as a 6s (25 volt) setup and I'm using the Turnigy 1.3 6s packs (I'm getting 13 minute run times!). The helicopter came out of the box with no bent or broken parts and in a hover it has no vibrations. After 3 flights of tuning and getting use to how it flies I was doing rolls, flips, tic-tocs and inverted hovering - this unit had no problem with any of that. This is the newer PRO model which has a re-designed airframe that has a higher COG, meaning more responsive rolls and a more crisp feeling. The

STAY AWAY!...soft aluminum all around :(...scratched the inside of the tail case by just inserting the boom!? ..Tail case misaligned, machining fragments all around, VERY soft and useless dampers on head. A total waste of money..Anti rotation pin on swash plate popped off! Whoever assembled the swash, stripped the hole and just glued the pin back in...WTF...
I should have known better...this is my second HK kit, thought hobbyking got their act together....NOPE!!....to the trash it goes!

I built and it flys! I followed the youtube builds carefully and took my time. My first heli build. Heli went together easily. Had to open up some of the holes to get bearing blocks aligned. Tail assembly came put together with thread loc but not the head. The main blades were perfectly balanced right out of the box. Seriously, mine were perfect. The main gear on the other hand was not round and although i managed to get it meshed with both the pinion and tail gear the tolerance was variable and made a strange noise so i changed the whole thing out for an Align main/auto/oneway assembly ($19.99 CAD). Big difference.
The zyx-s setup was pretty easy and works well with orange sat rec. dont forget you need the zyx sat adapter lead.
