I searched and could not find a definitive procedure for converting a Fury Extreme to FBL. Does anyone have a link or could outline the procedures here that would be appreciated.

I have been out of the scene for a couple years but still have 5 Extremes, I would like to jump right back in FBL.

Thanks in advance.

Do you want to waste $$$ on a FBL head , or easily modify the standard head ?

I modded mine , both Extreme and Tempest head , and the Fury 55 head too ..

Simply remove the flybar assy ; leave the bell mixers on the grips , then extend the rod from the bell mixer that used to go to the flybar carrier down to the M3 bolt near the bottom of the head . You'll need to space it out from the head about 6mm , I used the bolts that clamp the (metal) head to the shaft..
then fit your electronics , BeastX is fantastic !!! , setup as reqd and go fly!

Use a Mikado or other( align 600 works , but need to rake the antirotation bracket forward a tad ) 10mm hub to lock the swash ...

RJX head and vbar!

I have converted my Fury Tempest and my Synergy and both are flying extremely well!

Very easy to implement.

You should be able to make any 50/600 size head work, they all use 10mm main shafts.

Converting the stock FB head:
The distance from center-line of the head to the center-line of the grip ball should be 32-35mm on a 50/600 size FBL head to get proper resolution. On mine the length of the ball and extension is 14mm, yielding 34mm from head center-line to ball center-line.
I made extensions, but I would think a extended ball should be available, 12-14mm should work.
I used the RJX arms and clamp for swash anti-rotation (Helidirect is one of many that carry it)
It flies great and cost $30 for the conversion.

I did the above mod to mine first , then changed it to leave the bell mixers on .. It feels much smoother ie more X-cell like , with the mixer !!

I think it's illegal to fit rjx parts to a MA machine..

The Fury is very easy to convert because the centerline of the grip ball is in line with the centerline of the head. This is required for proper phasing when using FBL. Correct phasing is necessary or cyclic inputs get mixed and you will get a bit of aileron when you apply elevator and visa versa. It is one of the few heads that is like this.

And if it takes RJX to accomplish it, so be it

One of the few inexpensive upgrades for the Fury.

Of course, you can buy the MA head for $234.99 if you wish.

I've been flying my Ion-x ( = electric Fury extreme) FBL for over 2 years now, no problems.

I used MrMel's tip which was to just replace the stock MA grips with Quick UK Raptor 60/90 metal grips. These are a direct fit/swap on the Fury extreme head. I got these at;
http://www.ronlund.com/mm5/merchant...Code=QUKR6H-08B

Also used the Mikado swash driver. Got it from;
http://www.readyheli.com/MIK4018-Sw...mm_p_35279.html

I personally don't like having the blade grip balls facing outward. If you use a lot of +/- collective pitch, they could pop off. This is the reason that no FBL head is made this way.

MA will be be producing a 90 sized FBL head later this year. In the meantime they strongly recommend you do not use their current 50 sized FBL head on a 90 heli.

Cheers,
TomC

Fastflyer20, Is there any reason why the ball standoff on rotor arm should be that far from the Hub.

JustinStuart, Can I just buy the tempest grips to put on the stratus head? Also, is that the 3d or FAI extension on the grips. And what is the part number for the small ball link extension? That is the exact setup I would like to use.

The pitch arms are the "FAI style" and the small spacers on the end are called "negative delta spacers". You can actually use the MinAir double balls instead, but since my MinAir is a gasser, I wanted to "lock" the links on the end so that they could not vibrate off.

As for putting Tempest grips on the other headblock, I do not know. But if you give MinAir a call (or PM them), they can tell you for certain.

IYKIST - it is due to the restitution required by the servos and as I understand it, a 50 size should be around 32-35MM from the center-line of the head block/main shaft.

I understand it, a 50 size should be around 32-35MM from the center-line of the head block/main shaft.
Irregardless of the size of the helicopter, the ideal ratio for the distance between the balls on the blade grips and the distance between the balls on the inner swash ring is 1.5 : 1

So if your inner swash balls are 35mm from one side to the other, you want your blade grips balls to be 1.5x35mm or 52.5mm from one side to the other.

If you can keep the ratio around 1.5 you will get good performance.

I have flown early FBL setups where the control rods from the inner swash ring to the blade grips were nearly parallel, and even with tiny servo horns to improve resolution, it still flew poorly.

With my Tempest head conversion using the FAI arms, the ratio is exactly 1:1.5 and it works out pretty well. If you get the blade grips balls too far out, you do not get enough pitch. I have seen Align heads modified in this way, and the helicopter has a very slow roll rate. But it's definitely better to have too much resolution (and very little mechanical advantage) than to have too much mechanical advantage.
