WFP is an extensive modification to Red Baron.
I have completed and will soon release a modification that will allow you to fly some two seaters early in the war. The flyables will be the Aviatik C.I, BE2c,and Farman F.40. They will be flyable from August 1 1915 until January 1 1916. It gives you a little taste of two seater duty before transitioning to scouts.
All new cockpits have been made for these types. Appropriate missions are assigned. Appropriate flight models and damage models are used. Observer gunners work properly (rear in the Avi and BE, front on the Farman).
I have already engaged a Caudron G.IV in an Aviatik - good fun
