Transmitter Switch Modes for ArduPilot

When operating an R/C vehicle with a control board like ArduPilot / ArduCopter / ArduPlane, a standard feature is the ability to switch between flight modes (like "stabilized", "circle", "Return-To-Launch") using switches on the transmitter.  With the combination of a two-position and a three-position switch, any one of six flight modes can be selected.  A good article on setting this up for various transmitters is here.

Here are the settings for the transmitters I use:
 
Futaba 7C setup for six modes using switches D & G:
  PARAMETR CH5-SW>G
  E.POINT CH:5 UP 47% DN 48%
  SUB-TRIM CH:5 GEAR>+60
  P-MIX1 MAS>OFS SLV>CH5 SW>D-UP RT>-50%

Futaba 9C setup for six modes using switches C & D:
  AUX-CH CH5=>Sw-C
  SUB-TRIM 5:GEA=>-60
  ENDPOINT 5:GEA 48% / 47%
  REVERSE 5:GEA=REV
  Mix PROG.MIX1
    MAS=>OFST, SLV=>5, LINK=>ON, SW=>D, POSI=>DOWN
    RATE=>+50%

Alternate Futaba 9C setup for six modes using switches C & D:
  AUX-CH CH5=>Sw-C
  SUB-TRIM 5:GEA=>-80
  Mix PMX-6 CRV
    MAS=>5, SLV=>5, LINK=>ON, SW=>D, POSI=>DOWN
    POS 1=>-77%, (2=>-40%), 3=>-47%, (4=>+10%), 5=>+77%
      (position 2 and 4 have no effect)
