Thanks .

Are you talking about the mini overhead? What aircraft? There are snippits available from folks who have already programmed it. Select your device in spad, the click online snipit and download one. Also The folks at spad have done wonderful walkthroughs on how Spad works to interface with common hardware.

Its the mini overhead from flight sim pm 737.

Never used spad as yet.

Can u help me out ?
