At first I wanted to rush through this plane on my way to Javelin. I had 140k free xp, "oh it will take only 100k if I don't elite this thing, don't research expensive top engine and gun". Then I found out it's much more difficult to operate with 4 Hispanos when I had 6 of them on the previous tier. Then I kinda liked how this thing flies and the role you can have with 16 rockets and this speed - disrupt all enemy cap attempts and so on - so I said "what the hell, let's max this thing out and see what those ADENs are".
One of the best decisions I made in this game.
The ADENs trajectory and shell speed take some time to get used to. But once you master that, flying this thing becomes a joy. Fulfilling requirements for Specialized status never felt like a grind, not for a second. And once you make it and do what I did here with the guns, this thing becomes an absolute beast. Being a Tier 9 you'll have a lot of battles with Tier 8 where you are a nightmare for any RB-17 or GAA. Even in tier 10-9 battles, you are a devastator. For all the bombers & GAA, regardless of how tough they are, it's a single pass.
Quite frankly, now I have doubts about the Javelin. It also pack 4 ADENs but here they are grouped under the nose and on Javelin they are on the wings and need to converge - read as dispersion - but we'll see.
This is what I did with the plane. The pilot needs MM II, you'll have to master the weird (slow) shell trajectory, but now it's simply the ultimate HF hammer.
