Hiya fellas.

Apologises for being so quiet.
Thought this might be of interest in here.
I can see a HH with this

.....................................................................

With the new X4 FBL bits coming out, thought it might be a possibility of using the lower X4 FBL mainshaft and maybe a X5 FBL on our Hurricane 550's. After looking at few of the exploded view diagrams, it looked like that a few bits were interchangeable.

So ordered both the X4 and X5 conversion kits to see what was possible.
.............................................................................
Will update the text here over the next few days.. For now, lots of pics

..........................................................................................................

Sorry about the backdrop.My hobby room has been taken over by bathroom reno stuff

...................................................

Ok, i ordered the X4 FBL conversion set and the X5 FBL conversion set(doesn't come with blade grips so got some aswell)

The X4 kit comes with FBL mainshaft(shorter then the stock hurri), washout arms(swash lock arms), complete head(grips,grip extensions,headblock etc), 31mm link rods.Ball links and associated bolts etc.

The X5 kit comes with FBL head, longer link rods(50mm iirc), blade grip extensions,washout arms(swash lock arms) FBL mainshaft,ball links and associated bolts.

The instructions for each conversion. X4 on the left, X5 on the right.
The X4 has two holes in the mainshaft.Lower one is the main head bolt.The washout arms are screwed into the upper holes on the headblock(threaded) and protrude into the mainshaft.

The X5 uses the single mainshaft bolt to secure the washout arms aswell as the headblock.

X4 FBL complete head assembly

Headblocks side by side. The holes visible are....on the X4, for securing the washout arms.Threaded hole.There is another hole just under going at 90 for the main haedblock bolt. On the X5, main bolt hole witch also holds the washout arms aswell

Headblock diameter same. The X4 comes stock with black dampers.Softer of the two.

Mainshafts lined up

X4 FBL and X5 FBL mainshafts. Collar up are the same distance

X4 FBL and X5 FBL grip extensions overlaid. Identical

X4 blade grip. Suits 10mm root.ie 425's

X5 blade grip. 12mm for 500's +

X4 and X5 spindle shafts. 6mm diameter. I forget which one is which

Same bolts and spacers used.

Dampers. Same dimensions. Black is the softer of the two. 75 compared to 95 iirc

Washout arms.
X4 ontop is shorter than the X5. The X5 has a very large swash compared to the hurricane

X4 washout arm

X5 washout arm. Substantionally longers

Both the X4 and X5 heads allow the same amount of travel

The X4 head asembly sits about 15mm lower than the X5

Fitted with the X5 FBL head. Sits much much nicer than the higher stock hurricane. About 20mm lower

Boom clearance with the X5 FBL head

Now with the X4 head. Subtract a further 15mm

In the end i went with the X4 FBL head purely based on the low look. Both head assemblies will work.

To do the conversion with the X5 head....

Parts needed.

X5 FBL head assembly. Ie. Head block, grips, FBL grip extensions, 50mm link rods, X4 FBL mainshaft. X4 FBL washout arms. 35mmx 3mm bolt(comes with headblock)

X4 conversion.
X4 mainshaft, headblock, X5 main grips, FBL grip extensions, X4 washout arms,31mm link rods, mainshaft bolt(would come with headblock, i think)2 x 3mm x 10mm bolts for washout arms

I would suggest using the red dampers when using 550's on either setup

Now to fit the BeastX and see how we go

Good stuff Vas. What helicopter did Gaui make the X4 head for. I have never seen a Gaui X4. Judging from the pics I would assume the root on the blades would have to be 10mm?

I will wait until you get time to update the text before asking a bunch of questions. Although I probably won't be going FBL anytime soon it is nice to have all the info.

This X4 is a mysterious beast! Some sort of 425 v2. No mention on Gaui's site and no parts listed from what I can see. Though it appears you have Gaui made parts. It was put together by pitchup.se I think

Text added.

Heya Jerry. Chipbutty is correct and the original named X4 was developed/produced by Gaui for pitchup. The origianl X4 featured direct to swash setup with 425/550 head and the 425/550 gear train.

I'd say these new X4 head parts are an offshoot of the X5 assemblies and aimed at the Gaui 425.
An upgrade of sorts. Hence the 10mm blade root

All the parts are listed on the Gaui website.On the new products pages.

I'm very impressed sir... Love the Bobby Watts canopy! Any inside info as to when Gaui is going to come up with an FBL system that doesn't use a separate swash driver? Scott

Thanks Scott. Is all fun .I guess that's just another thing that makes the hurri so nice

I took the shelf canopy out for the photo shoot.Have to put her best look on

Is not a flying canopy

As for the seperate swash driver,i'm not sure i follow. Thought that the above pics covered that bit. I really held off going FBL with the Hurri version as i had severe issues looking at the swash lock setup and 3 storey high head. Just looked wrong. Will say one thing though. Some new Gaui's are about to come and might have ummm different swash lock setups on the FBL versions. China model show is at the end of April and supposed to be a few announcements
