I have a X-55 and would not recommend it. After few months of useage the joystick the joystick buttons stopped working, only way to get them to work is to hit the top of the stick and comes and goes. Springs could be better.
For $250 it's a "great deal" but in order to get a price of $250 they use the cheapest Chinese parts. So don't expect it to last long.
RGB Throttle is ok, but I can't assign RTY dials in DCS and same for M.2/M.3
Oh and for warranty,
I suggest you read this......
I got no where with them, bottom line support is terrible. x56 i expect it to be no better.
