My thoughts so far on my X55 ownership
I have one and its a very good flight stick. I really liked the X52 however this takes everything up a notch, and has way more buttons, which is handy for elite.
there are a number of questionmarks over their QC however with a greater than average number having niggles.
There are also a handful of issues with them which are fixable our end, but still less than ideal for a stick pushing £150.
(I for instance was getting ghost key presses when using the throttle - which was infuriating on elite when I suddenly emergency ejected my entire cargo on coming into land.
not only did i lose all my cargo, I got fined for littering to just top it off.
When it works though it is fantastic. its a nicely chunky piece of kit and really helps sell that feeling of you are flying a proper vehicle.
hopefully my ghost keypresses are fixed now (disable usb legacy support in bios and use USB3.0 port) apparently this fixes it, however i need to keep testing for a while to be sure. I have submitted a ticket too to saitek.
Whilst it does not sound like I am really endorsing the stick, so long as it now works properly after sorting the usb I have no regrets buying. it has a twistable shaft so you can yaw without having to buy pedals, which is a big advantage over the thrustmaster warthog imo.... though the feeling of quality of the warthog is at another level.
