I don't understand your topic.
I use the B17 frequently and don't seem me absolutely that the guns of the B17 are overmodelled.
Before understand like use the guns correctly and learn to shoot in deflection, I have been shoot down dozens of times.
You are enough look at my kill ratio for become considers that the B17 is an easy prey, for whom he has understood like carry him attack to this type of airplane.
Absurdity seems me that you claim that flights almost disarmed.
If you are not able to individualize a technique for strike the B17, simply, avoid them.
You don't ask that comes transformed in C47, those, in the arena, there is already.
Is easy and comfortable, attach a big slow target, hoping that it don't defend, take yours correct portion of risk and, please, use the training arena.
