I have been playing AH2 for about 2 1/2 years now and as far as I can make out BnZ is my least favourite tactic.
I would like to say that its because I am a knight of the air and like to do battle with dignity but such is not the case. It is because it is just too difficult.
WW2 Aircraft have such low tolerance to speed and G-Force that with combat you only have one chance to pull off a succesful attack.
If you find yourself only having one chance to pull of a successful BnZ pass, that just means you really don't know how to properly BnZ. Which could explain why such a rather simple tactic is difficult for you.
Now the ratio changes with the aircraft your flying, the P-51 seems to be the worst choice and yet it is used by so many for this purpose. It is an unstable firing platform and compresses easily. And if that werent enough the 50's do little damage unless a decisive burst finds its mark.
The P-51D is probably one of the better BnZ planes in the game. It is stable, in both flight and as a gun platform and if you know how to aim, those 6x .50 cals are deadly. The fact that you really don't know the characteristics of the P-51 could explain why you have such a tough time with a simple tactic like BnZ.
The Typhoon and Tempest are the best at this role, the Hispano cannons have brilliant ballistics and do tonnes of damage with just one hit and both aircraft have high tolerence to speed and G.
So with all this in mind, why do so many follow this tactic, well my response would be that they do not know the performance of their aircraft and the little tricks assocsiated with it to fight in a turn or E battle.
So it seems that the most difficult tactic is by far the easiest.
Any thoughts?
You probably have more success in the Typhoon or Tempest while "BnZing" because run away...err I mean extend half a sector until the other guy gets bored and you come back for a pick.
My suggestion to you would be to chuck your hubris about how great you are and how you can whip anyone in a Spitfire Mk XVI and seek the help of a trainer to learn basically what is one of the most simple tactics to use and learn how to properly BnZ.
