Snail,
if i see that diagram right, from 600m and with an impact angle of 50 degrees (very poor hit) it still could penetrate a 35mm thick armor.
This remark made me review a number of films again.
I know that the most important part of my success in the Hurri D (and, to a lesser degree, the IL-2) is the fact that I'm diving steeper on my prey than the majority. Many players just fly towards the tank and shoot at whatever angle they just happen to have. Now I checked the last few films and found that most of my kills had been made at angles between 45-50 degrees only. Even for me, who is very much used to that plane & tactic, establishing angles of 60° or better (which is mandatory vs better protected tanks like the T-34) is a pain in the butt, so to speak.
So even with the (supposed) superior penetration of the BK 3,7, the best bet for the 'average' player may still be to use the real world tactic and approach the tank on the deck from rear or sides.
But with a plane as slow, big and relatively little armored as the Ju-87 flying right into enemy MG and cannon barrels, it might lead to a surprisingly high number of casualties...
I just can't wait for it!
