Thanks for the excellent diagram. Not quite clear on the following:
2 Xdcrs(contains 4x triple potentiometers per axis).

FCPC1 & FCSC1 driven by separate linkage. (Dual Channel output 4 potentiometers, 2 unused) per axis.
FCPC2 & 3; FCSC2 driven by the other linkage (Dual Channel output 6 potentiometers) per axis
So what you are saying is that:

The system has a total of (4 x 3) 12 pots per pitch and roll axis, total 24

FCPC1 and FCSC1 each get pitch and roll, triple redundant, 12 pots (minus 2 ?)

FCPC2 and FCSC2 each get pitch and toll, triple redundant, 12 pots

Question: Why are two pots unused ?.

Looks like a clever design though, in that the redundancy even extends
to the mechanical linkages. In the unlikely event that one linkage
disconnects or breaks, the second linkage and potentiometer set would continue to
function.

Question: What is the function of the solenoid and does that lock the
stick at any point (zero ?) in it's travel ?.
