Alan, for the "check takeoff flaps is set" you can assign a function value:
If the flap position is not set, RF link will not go live.
This is one of the auto sensing items, just like on the latest Boeing ECL system.

The auto sensing parameters I use on the A-10 are:

. Engine switch OFF
. Flap takeoff position
. Gear down
. Brakes ON
. Canopy open ( to access some switch )

Also note that this check list is model dependent. So the auto sensing values can be customized for each case...
