Ditto here. Definite difference I notice.
One interesting experience was the deacking process - I've strafed the ack guns with a P-47, and was frustrated because it won't go down. But then, when I strafed with a mere 109 with puny guns, the acks went down on the first pass.
This was so peculiar, that I've decided to check convergence ranges on the P-47, and try various settings for ack strafing.
Well, waddayaknow.. when the firing range is off, all the bullets you fire from a wing armed plane like the P-47, tends to miss. AA guns are very small targets, and all the bullet streams land on either side of the ack, but never the ack itself. Only at a certain, single distance where the convergence was set, the acks were hit and went down.
I think it'd actually be better to aim slightly off the center when strafing acks, if you are in a plane with wing armament, to acount for the problems met with convergence.
