HK-450TT PRO V2 Flybarless 3D Torque-Tube Helicopter Kit (Align T-Rex Compat.)
HK-450TT PRO V2 Flybarless 3D Torque-Tube Helicopter Kit (Align T-Rex Compat.)

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!

• 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.

very happy with this heli just on 25 hours of fight time iv whore out bearing in a trunigy 500x 4000 and a few parts in this heli but for a cheap kit i love it here is a video of it in flying *******youtu.be/-rWZoYQmx_8

This kit came with imperial-sized screws (those small ones). I.e. 1.5mm hex screwdriver is too loose and 2mm doesn't fit. I had to purchase an imperial-sized hex screwdrivers set like this one http://www.hobbyking.com/hobbyking/store/uh_viewItem
.asp?idProduct=49405 P.S.
This is my first heli kit so it might be obvious to more experienced modellers.

On my previous searches around the web, all pointed to the H-1 configuration, but my mind was always looking for the 120º* of the swash plate hehe. But now I´*m convinced. Thanks again and keep the good work. PM

I bought this heli and the Tarot ZYX-S2. I have the Futaba T8FG and my question is: Do I configure on the radio, the normal 90º* (H-1) or the 120º* (HR3) swash plate? Thanks in advance. PM

The ZYX requires all swash plate mixing to be disabled in the transmitter, so probably "normal 90" should be used. I have used the ZYX with a $pektrum dee exx 8, and on that TX the correct swash setting was called "1 Servo Normal". HTH

What size screws does it use? I'd like to replace all the screws with better quality ones.

Hi there, I got this kit 5 months ago with the intention to build however most of the kit was not up to what I would expect sadly, I ended up replacing all screws with align ones. Much stronger and never had a problem with them.

This kit is excellent value for money. The new head is smooth and works well. The swash is very good and smooth, The tail has a new type slider on it and mine has no slop, a first on this size of heli, the tail holders seem to have a counter weight system built into them. I am amazed at what you get for the money. The blades that came with mine are good quality and usable.The torque tube seems a good quality unit and the drive is free from friction and hopefully static. All in all I am well pleased with the kit and look forward to getting it in the air.

got this today, it is such a difference to my HK450 V2, looks ace. Te screws are a lot better than on the v2 models. The FBL head looks also better than the one I have for my v2 but I did not fly it yet.

I'd prefer if they would include a glass fibre canopy but will just get one with my next order.

Finished the kit assembly and have now flown around 15 flights, sport flight and a lot of flips/inverted/rainbows/loose tictocs/punchouts etc Quality overall is pretty nice and looks great in black, one carbon frame half is rattier than the other (as usual with hk) but the mechanics of the frame, head and most of the tail are really solid. Head is rigid with no slop and feels nice and high quality. The all metal tail slider mech is a nice touch although the one problem I've encountered so far is that the brass tail slide bushing broke in half during the first test hover meaning the tail control arms weren't in contact with the slider anymore. Lost tail control in a low hover because of this so watch out. Never had this problem on other clone 450 tails so hopefully it's just my particular part that was a dud. Other than that the heli is great and flies insane with the following loadout.

the quality is amazing. the head has absolutely zero slop in it, is very rigid, and smooth moving. i can tell it will be great for 3D. i still need to check for WARP in the gears but the tail gears came slightly warped, a few teeth are stripped at the root and is not smooth at all. yours may come without it bent like that, but the hk helicopters usually just need align gears and youre good. the TT gears are usually soft and would not recommend flying if they dont seem in perfect shape. to be honest, i did not like the 450 pro i got last year but this one looks like a step up. will be using my zyx and nano techs!

- The carbon fibre frame is a little bit rough on the edges. Need a bit of sanding. Appear not as well made as HK450 V2 frame.
- The flybarless head looks very well made. The swashplate is very good, tight tolerance, not as loose as V2 swashplate.
- Torque tube tail end is good too.
Can't wait to fly it !!
