I always wanted an X56 stick, but went for the Thrustmaster t1600.
Can't say anything negative about the new model from Logitech (X56). Some say the price is rather high.
It ain't high. When you get a full set of the t1600m, you even get a pair of rudder pedals, this price is higher.
Setup? Just pick custom profile in ED. Works right out of the box(es) for me. I do have the TARGET installed, but since my keyboard isn't English layout I have to switch if I want to use the application.
So this is what I can tell you about the set so far:
Main stick, USB connection. 8 way hat on top. 16 buttons total, 12 on base and 4 on the stick itself. Small sliding throttle. Twist function on stick.
Hall Effect Sensor (magnetic..), for measuring the position of the stick. The hand rest can be switched between left or right handed. Two sticks can be used at the same time using TARGET software.
Throttle, USB connection. Sliding throttle. Do note it does not have any notch or so for the middle!
Axis: The throttle itself. The built in rudder. A mini stick. "Antenna wheel" (you use the pinkie finger for this one).
A connector for the external TFRP rudder, also this gives you an extra 3 axes.
Small screw under the base for tension adjustment.
14 buttons + 8 way PoV hat. Two 4-way hat switches, 1 push mini stick, one 2-pos. slider. The PoV hat has a button aswell.
The throttle is missin a "notch" that would be something good, so if you want to have it centered you need to find a solution, where you can see it somehow.
Not much to say about the rudder itself. Like the rest it's made of plastic (of some sort). They can be connected either via USB (if bought separate, an adapter is included), or directly to the throttle. They have air-brake features if wanted to be used in say DCS.
Both the joystick and throttle can be mounted to a cockpit with 2 M6 screws/bolts. The threaded holes are "offset" on the bases, so bottom right and top left on both of them.
They might not look like much, but they do the work. And combined with rudder pedals, you get real freedom.
Also, as another forum member said, the throttle sits on "rails" these are lubricated from factory. But not much.
I can strongly suggest silicon based lubricant for it, and much.
Sorry for such a long post.
