Hey,
I use a Saitek X52 HOTAS since Elite's release and there are a few buttons/sliders which I never found a use for. So, what functions have you applied to the following knobs and sliders?
1.) Precision Slide: it is the small slider on the upper side of your throttle;
In combat mode I use the Precision Slide as a toggle for FA on or off. I also use the Wheel Button on the throttle as a hold for FA off.
In analysis mode I use the Precision Slide for tuning. I use a large deadband so only the top and bottom part of the slide is used.
2.) Rotary 1 and 2: the small wheels on top and front side of the throttle;
In combat mode I don't use the Rotary 1 pot but use its button to enter head look.
In analysis mode I use the Rotary 1 pot for absolute tuning. I keep it set to Ammonia Worlds as ELW and WW bracket that frequency. So a quick look using a macro* that enters FSS from speed lets me know if I want to stop and examine the system.
In combat mode I use the Rotary 2 pot for the radar and the button as Fire Group 2.
In analysis mode I don't use the Rotary 2 pot. I use the button to fire the probes.
3.) Ministicks: on the front side of the throttle.
I don't use the Ministick but I use the [enter] button to see the backside

of the planet in FSS.
* It took me ages to get macros to work.
FYI You need to delete the 3 pinkie modes and not have the HOTAS properties open for it to work.
Also out of laziness I sometimes use the same fire groups for FSS and combat. I get warnings about not being able to use "this" module in that mode but who reads warnings anyway?
And talking about the X52: Mine is getting on ( > 5k hours) and some of the buttons are giving "double bounces" e.g. when I pressed deploy hardpoints it deploys them and about 60% of the time retracts them immediately. That can be worked around using the software.
