I use the middle (F1) as my mode toggle between modes 1 and 4 to get up views on the 8-way hat switch (A1 mini-stick) mode 1 is look around and mode 4 are look around/up views. The 8-way hat was slightly off centered which is why I had to calibrate - no issues since.
Left side F2 is my map toggle
I haven't figured a use for the right side F3 just yet (new stick and all)
The left lower "swivel" - mine is self-centering and has a nub - I use it for flaps up/down
The middle (Slider) is the throttle.
The right lower swivel I have set for elev trim up/dwn - it's just a rotating wheel both ways.
I use the top right hat (A4) for my auto pilot stuff and the press for damage report
I use the middle hat (A3) for eng toggle, dive flaps, gear and tailhook with the press being wep.
I use the lower side hat for level bombing stuff (still figuring this out)
The other buttons and triggers are for guns/zoom and ord selection/fire. The speedfire trigger are my guns and the regular trigger is for check 6's.
I think I have a fairly logical and useful setup, but I'm still figuring it out...
Haven't set mode 2/3 for gunning and GV's yet, but i'm sure it will pretty much all be on the stick with left over slots.
I have TM rudder pedals and have the twisty function disabled.
