ok new question is there any weakness that I should look out for? except steep dives( I did that before I made this post)
All planes have their weaknesses, for example the B-25H isn't very maneuverable so it's really not that smart to try and dog fight it. The rear gunner position is also very easy to take out, if you're being attacked from the dead six position, it is very important that you shoot the attacker down as quickly as you can before he gets in too close or he'll take out the rear turret.
It also doesn't have a bomb sight, so you really have to know where to aim for bomb drops. Also, since the elevators and/or wings will rip off if you try and pull more than 3Gs in a fast dive, it's best to use shallow dive bombing techniques if you plan on using it as a bomber. Even though its got waist guns, visibility is rather limited in these areas, best to use the top turret to engage bandits attacking from the port or starboard side.
