Try a Fw with 4 cannons...Go external view offline....You will see muzzle flashes on all 4 cannons if you hold the trigger down untill it is empty ammo.
The outer cannons show muzzle flashes even after the ammo is depleted.
Now try same FW....Fire the 4 cannons off and on till the outer guns empty..If you look you will see the outer guns no longer have muzzle flash.
