Mapping key commands using RealAir Duke

Hello. I would like to map the cowl Engine 1 and Engine 2 cowl flap switches on the RealAir Duke. I figure they should work with either of these two mappings:INC_COWL_FLAPS1DEC_COWL_FLAPS1INC_COWL_FLAPS2DEC_COWL_FLAPS2or justINC_COWL_FLAPSDEC_COWL_FLAPSThe FSX default Baron works fine with either of these mappings. I was able to map GEAR_UP and GEAR_DOWN for the Duke so maybe cowl flaps can't be mapped, which would be disapponting because my Saitek hardware offer lots of button possibilities. Anyone else try this?Thanks,Scott
