Much better quality than the standard HK450 GT head assembly. Much tighter and less vibration mid air.

Very nice complete head for the money, was different to the head that came off my HK450 but it will fit. This head assembly is also compatible with the genuine Align parts so as it wears out you can use Align parts to trick it out.

There was a lot of slop in it and at the same time half of parts couldn't move freely. I thought it was badly assembled so I decided to disassemble it completely , grease and assemble again.

What I discovered was terrifying. Where to start.... I'll write below everything that was defective (every part was defective but I'll give detailed explanation)...

Bearing inside blade holders were moving freely, no threadlock used.
Thrust bearings were dry. No grease used...
Six bearings inside arms (they were threadlocked) were glued completely so they couldn't move at all. That resulted very high resistance in moving arms.
Also, bearings inside flybar seesaw holder were moving clearly, no threadlock used.
Half of ball links were sloppy.
Ball inside swashplate couldn't move freely even after applying grease.
No bearings were used in radius arms resulting sloppy movements.
Screw hole on main shaft was larger than it should be resulting play of main rotor.

So, this main rotor is useless, it cannot be used at all.
It must be defective batch or something because other reviews tell different story.
But in my case I'm very disappointed.

I am happy with it. Main shaft were crooked and I've got to change it, but otherwise it's well made. Finish is not perfect but cannot complain with that price.

Well. What to say.... The product as such is OK, but some important details could be improved. Espetially the main screws, holding the ball ends in the swashplate coud be hex type, not PH. And the same is for the screws at the flybar control arms, whas-out control arms and mainly the those on the flybar seesaw hub. The Philips type of screws are totaly useless for the rotorhead
