The JU-87G w/ cannons was great in Warbirds, I remember chasing a JU-52 back to base while flying this special Stuka. He was outrunning me and between 4 and 6K out (it wasn't displaying the range anymore).
He was in level flight, as was I, and I was directly behind him. I shot my cannon 3 times, carefully trying to work out the elevation, and my last shot actually hit and tore his plane apart.
It was a one in a million shot, and the guy was absolutely shocked (as was I).
It's not dangerous enough to change gameplay for all you conservatives, but it's definately fun enough for those of us who enjoy flying this quirky and historical bird.
