Purely for my own education as I don't know the answer.
How common was gondola use by 109s? I went through all my 109 books looking for photo evidence of front line units with gondolas.
The only place I seemed to find them showing up consistantly was in the MTO with JG27 or 53 on their G6s. Were these for hunting Allied bombers or for dogfighting?
I'd think it was for bomber hunting but not for dogfighting as the performance penalty would have offset the advantage of the more cannon.
Again, like the Spit Vc, just because it could carry 4 cannon, doesn't mean it makes sense for the game.
Personally I don't care if a 109 driver has gondolas. I figure unless I don't see him, that he's going to be easier to kill with the added weight and performance penalty from the gondolas. And if he's a good 109 stick, he's not going to need em to kill me anyway

My feeling is folks are just desperate for the hitting power to make things go pop faster and that the argument that historically they could carry the gondolas is just a cover for wanting to make it easier to kill in a definately non historic fashion in the MA.
So I guess the other question becomes, would Erich Hartmann have chosen to take gondolas or not, since the 109 fans are all would be Erich Hartmann's anyway

This would be Johnnie Johnson would never want a 4 cannon Spit V in a dogfight.
