Thanks to all who have done this before - I have been researching as much as I can, and all I can say at this point is I am confused. I am trying to decide between a Leo Bodner interface card, Phidgets cards, or Open Cockpits cards as the way to connect my throttles to FSX. I can use either servo (R/C Hi Tech) or DC motors as drives with linear pots for position, but I know nothing about programming language. I have tried to find examples of code that others have used but so far I would not consider this a success. Can any one give me some pointers? Thanks == Jack
