SALUTE
Ar-196 seaplane - Fake Nakajima E8N Dave, there will be a small navy on both sides so seaplanes will add fun & interest.
Cr-42 - Fake Kawasaki Ki-10, it also carries bombs that you will need to stop the chinese advance
Gladiator - Fake random random chinese fighter.
MBR seaplane - Just for fun, i'm sure you will enjoy shooting them down.
don't worry, this list will be trimmed down as thiings progress.
