Just thought it was a bit patronising for somebody who was poor at grammar to offer advice, especially when suggesting something so parochial. Who knows or cares what a Photography 101 is? Is it relevant to a company based in HK? Also, a kid is a young goat. If you mean something else use the correct word otherwise you might as well go back to grunting incoherently.
Not really interested, if you can't be bothered to make yourself clearly understood by the rest of the world, why should anyone bother to try to decode your rants? Most people who don't have English as their first language still manage to make themselves understood, so just try harder.
The lack of a flybar makes the heli less stable. If you have a tail gyro, you can fly without a full FBL gyro (google for NOBAR), but it's not for beginners. Hovering should be pretty much the same as with an FBL gyro, but once you start to fly around and especially if there is some wind, well you'll have a handful!
The largest bearings go in the blade grips. I found the inner ones were a bit loose, and used some threadlock to secure them. Also be aware that the tiny steel washers go in between the small flanged bearings that are a tight press fit in the swash locker arms. Once those bearings are in place, they're hard to remove, so don't forget to fit the washers! (as I did! :()
There are 4 large bearings, two each for the blade grips. There are two thrust bearing assemblies for the main grips, and also four small flanged bearings for the swash locker arms. Note that you have to use the two small, thin steel washers between the bearings in the swash locker arms. Those bearings are a tight press fit, so hard to remove if you forget the washers.
It's unfortunate that the breakaway ball links that fit the Align and Tarot FBL heads won't fit this because the ball links are the wrong size. The arms seem to bend every crash and a new set of arms cost almost as much as a new helicopter. I was thinking you might be able to fashion your own breakaway balls using a some rigid nylon or HDPE tubing (1mm ID and 4mm OD or similar) a standard screw in ball link and some M2 threaded rod. The idea is that you'd screw the ball into a short piece of the rigid tubing then screw the threaded rod into the other end and then screw that into the arm and if the rotor hits something it would just snap off.
I received a Flybarless Head and due to the missing parts, I was not able to assemble the FBL. Please can somebody tell me what the total amount of items in this set is? The helpdesk was telling me that if I got all the parts from the original photo on this page, there are no parts missing. On the photo are 47 items displayed. I received 66 items. However, in the manual on this page are 70 items.
I got the same as you did. I used the dampers from the old head. The cap from the old head could be used, but i won't since it is just cosmetic as far as I can tell. If you do use it, make sure the screw is the correct length or it will interfere with the feathering shaft.
I'm very happy with the quality. Haven't flown it yet since it is -25 outside, but will soon.
If you are referring to the links that go from the swash to the seesaw mixing arm on the stock 450 pro, those worked fine for me from the swash to the blade grip on this FBL head. BTW, I did not use the feathering shaft supplied with this kit, I used the stock 450pro one.
The regular Pro 32mm links work fine. Compared with the FB setup on the Pro, you can raise the swash slightly if you want the swash locker alloy arms to be level at 50% collective - but it's not really important to have them set that way. The head has two mounting holes - I use the upper one, to lower the head compared with the FB.
I put together this head and I have found that there is a lot of slop in the swash follower arms. The instructions show 2 flange bearings per arm where as the kit came with only 1 per arm along with a bushing/standoff. The problem comes from the amount of slop in the bearing itself. What have I done wrong or what can I do to solve the problem?
I've attached a video showing the slop. I have not tried to fly with this head yet so it is brand new and has not been crashed or otherwise damaged.
It is hard to see but if you look carefully after I turn the head the spacer is there.
Do you have 1 or two flange bearings in each of your swash follower arms? In the spacer1 pic it looks like you have two bearings there, one on the inside and one on the outside. My kit *only came with 2 bearings, not 4.
Hi! Indeed, your spacer is there, and the kit came with 4 flange bearings 2 for each swash arm, 1 for inside, 1 for outside. Check all your peaces again, I buy 2 kits like that, and they came with all peaces.
I bought 3 of these heads, and only 1 of them came with all the pieces required to make it work.
1 of them had 2 of the larger swash balls missing (easy fix, use align links on the end of the rod)
Another has the pitch rods missing.
I'd say quality control isn't quite up to scratch. So I wouldn't doubt for a second that those flange bearing could have been missing from the kit and YES, there should be 4.
I've purchased 3 heads so far - 1 was complete and had 2 extra washout arms, 1 was missing 2 of the flange bearings (yes should be 4 per kit) and 1 was missing 2 missing 2 of the flange bearings and 2 blade grip bearings.
I only needed 2 heads but bought the 3rd for spares - lucky I did as it covered the missing pieces - lol
just awesome! watched your video and got infected :-) i puted microbeast and savöx servos in my HK450GTPro and this HK FBL head. GREAT, it flies like a big bird. awesome flips and rolls and hovers stable like hell! now i love my 450 :-)
A couple notes from when I assembled this head:
Additional parts required are:
- feathering shaft (51mm x 4mm)
- dampers (4mm hole)
- the thick washers that fit next to dampers
- washers that go under the bolts at
the feathering shaft ends
- two small 0.12mm thick washers
Some of these parts are included with the 51mm feathering shaft sold by HobbyKing.
- Order and direction of parts in swash follower arms is critical to get the alignment right
- the four flanged bearings go in the tops of the swash follower arms. Two per arm, one bearing in each side of the hole.
- I found that a small 0.12mm washer was needed between the flanged bearings, otherwise they would bind when the 16mm screws were tightened.
- the link holes in the swash follower arms are a fraction too large (4.8mm rather than 4.75mm). Personally, I would rather that they were too small, because they can always be reamed out. As it is, the only thing you can do is find some bigger balls.
There are a couple nylon washers included with the kit. Does anyone know where they go? The only use I can see for them is as spacers in the blade grips, to adjust for rotor blades with thinner roots.
Will spindles be available for this? I ordered one of these, its fantastic, but I dumb-thumbed my heli in inverted, and bent the feathering shaft, and when I went to replace it, found it to be considerably longer than a standard v2 feathering shaft. Anyone know what shaft will fit? will it be available here, or is this a disposable flybarless head?
You need the 51x4mm Feathering shaft. (I think the 450V2 has 41x4mm, right?) Some washers are missing, but you should have them from the original head, if it has thrust bearings and 4mm shaft, the washers will fit.
it says FBL in the title of this product. that's mean if you search flybarless, you can't find it.
1 thumbs up!
- 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.

sehr effektiver und preiswerter Umbau fr die 450er Klasse- wichtig unbedingt Blattlagerwelle vom Pro nehmen-
mit dem- Beastx - zusammen ein super Combo

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

this is not a straet fit on a 450 v2 as the fether sharft is to short you will need a 52mm sharft from the 450 pro not that mind but i have to wait for them to be in stock [hk y not put it in the bag]
