I know of three FS9 or FS9-capable Staggerwings.
SimTech and Lago both released payware Staggerwings, both on wheels and the Lago also on floats. Both are nice models with VCs. The SimTech one was later released as freeware, and the tag in the zip file tells me that my copy came from Avsim. I don't know if the Lago models can still be found anywhere, or if they were ever released as freeware. (I got my copy direct from the modeler as thanks for helping him with a paint job.)
Paul Clawson made a freeware Staggerwing. It's also a nice model, but it's old and has no VC. Paul's models can usually be found at AvSim and/or FlightSim.
The Lago and Clawson models were FS2002 models but they both work in FS9 (i.e., no missing props or other animations.)
