I was wondering if somebody has come across a problem I found during assembly of the flybarless head?The balls on the swashplate have been replaced with the ones supplied in the kit.However I have found if I operate the radio and activate the swash in roll and pitch the arms from the blades drop off the balls on the swashplate. My question is which way do the ball links connect onto the swashplate balls.One side of the links seem to have a small champher and the other side doesn't.So which way to connect?

Only way I could cure the problem was to refit the original balls and rod ends on the swashplate .

What spindle or feathering shaft works with this head, HK450GT or HK450PRO ´*s ?

450 pro ok

HK supply the feathering shaft and 4.8 mm balls for the swashplate now .The only thing you need from the old head is the head damper rubbers .

Does anyone know what size the links and rods are on the HK 450 FBL Head Blade Grips? I can't find them anywhere. I used standard Trex 450 links on the bottom of the long rods and didn't change out for the larger swash balls but had too on the wash out arms. It seems that the only way to get links for this guy is to buy a new head. I'm thinking 600 size links and rods might work.

Both of my heads came with four oversized link balls. I used two on the inner swash for the swash locker arms, but used regular HK plastic links on the bottom of the linkage rods from the main grips - leaving me two spare oversized link balls and two spare oversized plastic links. These heads seem to stay more slop-free than my Tarot heads, and so far I haven't needed to use my spare bits, after well over a hundred flights on each head.

Hi would this work on a E-sky belt cp v2 heli? thanks in advance guys

I'm pretty sure it will work. It's made for a 4mm mainshaft, and it has two Jesus bolt holes in the head. In the worst instance, you might need to adjust the length of the inner swash to main grip links. I love this head on my 450's.

2 Problems:

- it's not an update fr a HK450 / T-REX 450 but for the 450 PRO! You need dampers and shaft from 450 pro.

- The included golden washers are wrong size, they touch the inner ring of the bearings. Outer diameter is ok, but inner diameter should be >1mm larger. This is a big problem, I could not find these washers anywhere :( It _works_ with the included washers, but it is suboptimal, the gearings are not working smooth.

I managed to get this together and when put together correctly, it does fit and align as required. When assembling the swash follower arms, it's important to get the directions of the parts right, otherwise the alignment is out.
A small 0.25mm washer between the flange bearings stops them from binding when the screw is tightened.
The links on the plastic arms are a fraction too large. Align balls are 4.75mm. These links are more like 4.8mm.

bought 2 of these,really nicely machined well made unit. Requires 450 pro feathering shaft, and some Curtis Youngblood green(hard)dampers.
I'd rather pay more and have these included in head kit. Follower arms have very large and inconsistent ball link holes. 4.68mm to 4.84mm. No balls out there that fit properly and you don't want to lose these arms in flight, read major crash!! http://www.rjxhobby.com/Uploadfiles/450FBL.pdf (assembly guide pix
