Hello Schurem,
Yes, we do. There are versions of the Bf-110 ("Wilde Sau") and the Ki-46 with upward firing guns. I don't recall which mod-pack they came with (I'm still using a dinosaur-U.I. 1.0 install with other mods added), but I am sure you will find them through the search function. There may even be other aircraft available with a similar gun configuration. To throw in a little advertising: Even though it doesn't have upward firing guns, have you tried the He-219, my favorite Axis night fighter?
Regards,
RB

XB-49
i don't know why, but i really enjoy using this. i remember once barrel rolling around a Halifax, and hitting it the hole time!
Yes, It Rocks. The 110 is my fav. Against a formation of B-24s (in night livery of course) I have downed four before I had to limp home. Great Mod IMO.
