Well in addition to the Voison, which is still in 3D development, I've got a few other planes in FlightGear:

A 1914 Bleriot Militaire.

The Henry Farman 20..

Sopwith Tabloid floatplane.

Caudron 10 meter trainer

Barmy OFFer in questionable standing, maybe collapsed in a corner?

Join the few, the touched, the moon spacklers.
