Imported plane

Okay I'm not sure if this is something I am suppose to be able to do or not....I took a certain plane from CFS2 and tried to import it into FS9. It works...kinda. It's in the game and it flies but has some major problems. First, the landing gear is not visible and the control surfaces don't move. Second, it seems like the plane defaults to some little prop engine and sound (this plane is a jet). It sounds like a little Cessna and has very little power as it can barely reach 200 knots. So, my questions of course are: why doesn't my gear show up and controls move, and what file determines which engine and sounds the aircraft uses?
