The D-11 is actually slightly faster than the D-40, surprisingly both in mil and WEP and is a better turner. The D-25 is only nominally slower in WEP. The D-11 is almost always left out of AvA setups where it can be used because of the misconception. The M is the only significant European game changer in regards to performance.
You are never going to outrun a 190 or outturn a 109 in a D series jug which doesn't mean you can't stomp them if you play them well. With the Russian planes, te Luftwaffe will have their hands full.
The D-40 was equipped with zero length 5" HVAR rockets which were not used in the european campaign. Something else which was not modeled in the game and which is not well known is that the 5" rockets had to be launched before firing the guns, as the casing ejector holes were located as to break the rocket launch wires when fired. The D-40 RA block was built in the Evansville Indiana Plant. The were usually sent to the Pacific whereas RE Blocks built in Long Island, NY tended to go to Europe.
I'm not just trying to be difficult, I just like to see AvA be as good as it can be. You know I have been a big fan and supporter bringing folks in when there is a good setup. I wish it had the same appeal as the MAs. Two sides with low or no icons is the best immersion, not to mention the weather modeling.
Thanks again Jaeger~
