Hallo
I am a great collector of alot of versions of one plane in IL-2

(Bf-109, Spits, FW-190 etc) ... but..
for not overstressing our beloved 3d-artist we should only ask for the really final developement versions of the seafire and spitfire !
Seafire FR.47 and Spitfire Mk.24
In principle all earlyer variants (despite produced in important numbers) were developement steps on the way to handle the enormous torque of the mighty Griffons.
Whyle the Navy choosed the contraprop way, the airforce (they had trials with contraprops too) chossed the way of a way bigger tail/Keel/Rudder. already the last Mk.21 had these bigger tails.
The early Mk.21 were: " not flyable for average pilots..."
All of the last Spit-Seafire versions had the modified shorter AND stiffer wings for better rollrates
Its just my meaning

Thx @ all people who supporte the developpement of these powerfull planes
Cheers
Doc
