This is a very nice mod.
The B-25 is one of my favorite aircraft of WWII. It’s actually the first WWII airplane I ever saw in real life (B-25D in Overloon, The Netherlands), and the first WWII airplane I saw flying (B-25J ‘Sarinah’ of the Royal Netherlands Airforce Historical Flight).
I got all versions to work, but there are some problems:
1: The early A model does not have any tailguns.
2: The late A model does not have an upper turret and the nosegun is shooting to the rear (at the bombardier/nose gunner and the other crew members). Also the tailguns on the A late aren’t working. (Or does an enemy has to be exactly at my six?)
I did a test to check the nosegun behaviour. I flew in a straight line, untill a Zero was at my 7 o’clock, almost my six. (The Zero was slightly high btw). The Zero attacked me, and shot me up pretty bad, but the tailguns weren’t shooting back. The only gun that was shooting at the Zero was the nosegun!!!
I don’t have any problems with the B-25B’s. I hope that this information can be of any use to you.
I really like this mod, big thanks SAS~Riken!
