The P47 also seems like it collides with terrain a lot more than SCAS, but I haven't used SCAS in awhile due to liking other doctrines better.
If I was better at navigating the mod tools I would like to find what angle the weapons are fired at. P47s just seem to be fired at a tighter angle to the ground, which would cause the collision
I could be wrong, it could just be more noticeable because there's fewer projectiles and they are easier to see
BTW in the IL2 ptab thread I had said I could be wrong about them not being bugged. My point was that regardless it is
possible for them to still do really good damage, as my test showed. And at least with that ability you have full control of it. AT loiters might go after a halftrack if you get unlucky
