Don't forget that the first Il-2 started out with only 10 or so aircraft, and was considered state of the art. 8 years later, we have 300 aircraft. Patience.
Don't quote me on this, but as far as I can remember these aircraft are slated to be flyable:
Hurricane MkI (possible variants based on prop - sorry, tiny pilot not included)
Spit MkI
Blenheim Mk IV (aka Bolingbroke)
D.H. TigerMoth - 2 seat trainer.
Bf-109 (possible variants with or without cannons)
Bf-110 (D I believe)
He-111
Ju-87 B-2
Ju-88 A-1
Fiat G-50
Fiat Br.20 (bomber)
Su-26 as a demonstrator of the FM to current pilots, and just for fun
as AI:
Gloster Gladiator
Vickers Wellington
Avro Anson (2 possible types)
Avro-Rota Cierva Autogyro
Supermarine Walrus
Short Sunderland
Boulton Paul Defiant (possible night-fighter variant)
Blenheim MkI (possible night-fighter variant)
Bristol Beaufighter
FW-200
He-59
He- 115
Do-17 (two variants with differing engines)
Ju-52 (with and without floats)
Fiat CR.42
Bf-108 Taifun
Pretty comprehensive if you ask me, especially for a first release. With 3rd party input it will only get better.
PS- if anyone wants to update this list, go for it, I'm only going off memory.
