Yes I can map keys to incremental flap operation but i normally use one of the levers on the Saitek throttle quadrant to give continuous control. It is when you use a control axis like this that it does not work.
Roger...I forgot about the axis
If you have a registered version of FSUIPC4 you
can solve your issue in a couple of different ways. Creating aircraft.dependent
assignments for that axis and is the case of the Spit, have it send a single
Flaps_Up or _Down command when the axis is moved from each limit in
the proper direction. For the P-51D, create 5 incremental 'bands' to send '
the incremental flaps up/down commands when the axis goes through a
band in the proper direction.
If you controller software permits the creation of 'bands' for axis programming
you could just program the axis for the 5 'bands' that send the incremental
commands to FSX. In the case of the Spit, the 4 additional commands would
just be ignored. The software would have to be able to determine in which
direction you entered the 'band' in order to send either an up or down command.
Most controller software allows for different 'profiles' so that you can tailor the
axis for each aircraft and load the appropriate profile for the plane you are flying.
A more elaborate, rather elegant, solution would be to use a Lua script
to set the appropriate flap position based upon aircraft that is loaded
and the position of the axis.
