Short answer, NO as modifying Weapon Models, Damage models etc is prohibited on this site. Any further discussion of the subject will result in the thread's removal...

However, you're welcome to discuss tactics for improving early aircrafts' effectiveness -- i'd suggest ensuring that you always attack at relatively close range and make sure that you attack at where your weapons converge. I have mine set for 200m.
