Hi all,
This posting is almost a "copy and paste" of this thread that Scarecrow has linked and post it here again to share it with you -because I'm really,really very satisfied with this controller.
-smile-
And most of my inspirations to do something like this I got from this thread!
So I decided it's time to open a account here to be able to answer directly if you have questions .
First a video :
(BTW: if you are wondering what it this thing I tilt 90° and use as a collective:
A picture Tale:
"Dual Thrust" or "What I did in my Easter Holiday")
Short summary:
I always used a MS-FFB2 for DCS-BlackSchark but I was very unhappy with the lack of buttons on the stick in DCS-a10.
I switched forth and back between the Cougar and the MS-FFB2 - and this was very unsatisfying and I searched for a solution for this lack of button/lack of FFB dilemma...
Finally I found it by digging up this video:

And after some testing... (read more about my first steps here:
http://forums.eagle.ru/showthread.ph...91#post1304491)
...I was not really satisfied with the power of the FFB.
And after I opened my trusty (btw:8 years old) MS-FFB2 for the first time I saw that it might be is possible to attach a second mechanism to it to double the FFB force - so the extended handle will still be hold in place in every situation.
I also found out when DirectX send a FFB command it will executed by every FFB controller you add.
I found it out by moving my MS-FFB2 and saw that the Logitech FBB-steering wheel turned also in the x-axis the same as the joystick...
So I bought the second MS-FFB2 (at a price I don't dare to tell... the seller didn't know what he was offering... - I gave him 10€ extra in the end...).
When you plug in two MS-FFB2 - they will react in sync to a FFB command.
So I realised that I "only" have to reconnect some wires of the second MS-FFB2 to sync both. -
at least in DCS-Simulations.
Nice -isn't it ?!
So here is what I did

:
Here a some photos of the most important steps with explanation so you get a Idea what I have done.
They are not meant to use as a manual and there is no chronological order (!) - it's just how I did it... 
There are also some steps missing (I just didn't took pictures)
Using the methods / circuits / components / constructions as described in this document is entirely at your own risk.
If you damage your PC / Joystick / Keyboard / Yourself by any of the things I wrote down in this document, it’s NOT MY FAULT.

Snapper reported some problems in IL2 - The both FFB don't work in sync using my method. He will try a different approach using only one FFB circuit board to drive all four motors:

So If you want to build something like this yourself: ask me - and I will try hard to answer!
I use a old bass-box of a old 2.1 sound system as casing for the stick.

Here you can see how I attached the switch-panel (I used a unused part of the saitek throttle quadrant - that I use as a
dual-trust controller) :
Here is the stick in front of my (also) modified office-chair:

Soldering...
...even more soldering... (I hate this kind of work!

- but it is very important to do it clean with concentration! )

They just fit perfect and assure that the gears are already in the right distance!
