On the subject of the Hotas X (or 4 or One) lacking buttons, what I do is use all four buttons next to my thumb on the throttle stick as modifiers. For example, my hat stick on the main stick is lateral/vertical thrusters by default. With the top throttle button down it does pips, with the 2nd button it does targetting (next/prev ship, next/prev subsystem), with the 3rd it opens my various HUD panels and with the 4th is does misc' things (lights, nightvision, silent running and FA off). So that means I have 20 functions on the hat stick alone. Now, before people shoot me down (literally!) I will add that in some ways this is a terrible setup as it means I can't operate my lateral thrusters and my pips at the same time but, as a non-PVP pilot who likes doing a casual amount of everything, sometimes in VR, it works brilliantly for me because I have pretty much everything bound to this stick (including the camera suite and the DSS) in a way that seems perfectly logical to me (although I was told several times at Lavecon that it was "a weird and perverse setup".
