At last I'm pretty much satisfied with my Akers Barnes build. So far here's what I've got:
The seat and the Freetrack headset
G940 and G27
Control Panel. I will add more buttons as needed. I use HIDmacros for FSX assignments.
Rudder, plane mode
Pedals, car mode. The pedals board slides back and forth, and is locks in place in each mode.
