Love the kit, will by again for spares. I only swapped out the main gear since that was bent for a tarot main gear and use an align pinion. Compared with the assault 450 DFC this kit has an inferior rear rotor assembly in terms of play in the components. But all in all that is negligible and when build thoroughly and with good components, you get a very sturdy and reliable helicopter.

Not flown yet, but it looks like a great option for 1st 450, or a "spare" or lamb for learning new moves.

No manual or parts list provided so not recommended for newbies. Come well packed. Tail servo tray requires 35-40mm 'B' measurement servo where as the 3 cyclics must be micro sized.

I purchased this kit from HK to see how it would fare against other helis I have built and owned. Ill start by saying for the price its hard to beat but with that price comes downfalls. First thing I noticed off the bat is that the machining for the tail rotor feathering shaft was incorrect allowing only a few degrees of tail blade pitch to turn the nose right, to correct this I replaced the whole tail block assembly with and align 450 dominator TT tail. Continuing with the tail the tail boom block that comes with this heli is very sloppy, the horizontal TT drive gear is able to slide left, right,up, and down in its housing causing the gears to strip very easily and it almost caused a catastrophic crash, thanks Realflight for the practice Auto with tail failed training! As a temporary fix I applied electrical tape around the bearing to secure it but decided to replace it with and align TT pro tail housing assembly with black align gears which are said to be much stronger. However, this heli has many good features as well. The head was sturdy and well machined, the frame is stiff and looks great but make sure you sand the edges, the blades seemed cheap but they did the job. All in all, you will be satisfied with the heli but you need to be prepared to spend a few extra dollars on some of the quality parts that I mentioned to have worry free flight.

Bought this kit as my first 450 size helicopter. All the parts were ok, assembling the kit was easy. Only issue I have is with tail control arm which has a little slop at connecting point with tail hub control ball. This slop can be improved by flatten the arm circle connected to the ball.
Head is ok, managed to break a screw because to much locktite but found a way to replace it.
Canopy is bad but can be used, still I recommend to buy another from the start.

It is well made heli for its price, torque tube version has some pros and cons, but in general if put together correctly works fine. Don't forget to threadlock ALL metal to metal screws.
