Pete, thanks for the direction.   As a newbie Lua programmer, I was able to hack together the code below.  I read the x and right joystick inputs, converted into usable aileron, rudder, and elevator values, and sent to FS.  This at least gives me different parameters I can use to tune and adjust both in the lua module and in the aircraft.cfg for real-world flight dynamics of a paraglider.  Note that I did try to make the flaps work but was not able to get the controls to function correctly :(

	-- Read x and y linear inputs of joystick, calculate corrected ailerons, elevator, and rudder, and write to FS 
	--
	-- loop forever
	 while 1 do
	-- read x and y axis (joystick) inputs
	 x_axis = ipc.axis(1, "X") 
	 y_axis = ipc.axis(1, "Y")
	-- convert x and y axis inputs into differential aileron_value
	 aileron_value = (x_axis - y_axis) / 2
	-- convert x and y axis inputs into average elevator value
	 ele_value = (-x_axis - y_axis) / 8
	-- convert x and y axis inputs into differential rudder value
	 rudder_value = (x_axis - y_axis) / 2
	-- write aileron_value, ele_value, and rudder_value to FSX
	 ipc.writeSW(0x0BB6, aileron_value) 
	 ipc.writeSW(0x0BB2, ele_value) 
	 ipc.writeSW(0x0BBA, rudder_value)
	-- display in FS Window
	 ipc.display("X="..x_axis.."\nY="..y_axis.."\nAV="..aileron_value.."\nElev="..ele_value.."\nRV="..rudder_value)
