I know that in online play, new aircraft are invisible to other players but i heard that once another player has the the new aircraft too then they can see each other with them.
Me and my friend have decided to make a dogfight between FW-190 A-3 in an empty training server but we couldnt see each other and i thought we could if both of us had the plane.
So is it impossible to play online with new aircraft?

Yes, the host must have the aircraft installed, if a dedicated server, it must be running the modified Dedicated Server 1.1
