IMHO huge mileage could be had with the FE2. The B and D are differentiated primarily by engine (120 and 160 HP). It can also be used in drag as a Farman substitute. And who wouldn't want to buy one?

Here's the longer list. Scouts are OK almost beginning to end. The Halberstadt D.II and Nieuports 24 and 27 are probably the biggest holes, but they are not that bad. IMHO the minor types can wait (Morane N, DH5, Snipe, Roland D.II and D.VI, SSW. etc.).

Filling back to front:
1918
A dedicated recon for the Germans (LVG C.V would be my recommendation)
Salmson SA2 for the French.
British are doing OK.

Mid-late 1917
Dorand AR for the French
Strutter for French and British
Rumpler C.IV (honorable mention to Alb C.VII and C.X).


Late 1916 - Mid 1917
Farman F.40
BE2e
FE2d

Mid 1916 and earlier
FE2b (really just an engine change)
BE2c
Voisin L.III (honorable mention to Caudron C.IV)

Patrick has a good list.

I agree, Patrick knows.
No sarcasm, honest.

Good thing is 777 hold Patrick in good regards, maybe (just maybe really) he could talk some?
