Dunno about in WW2 but in Aces High 2 it only has 1 20mm cannon (with 120 rounds) and 2 12.7mm MGs.
I've recently decided to fly the Yak-9U a lot this tour, actually tonight was only my 2nd night flying it. How do you set your convergance? What's the longest range you take shots at unmoving targets on your 12? Do you fire both weapons together or keep them seperate?
It seems obvious to me that the P-38 armament is heads and tails better than the Yak-9U. More rounds, also nose mounted, twice the number of MGs, and although I've not fired the Yak's guns enough yet to know for sure, supposedly better balistics. I suppose it loses to the Yak-9U in weight... obviously all those rounds and the extra guns are heavier.
I think he made a typo.
The Yakovlev's armament is similar to the 109G's, and I feel almost as comfortable shooting in it as the 109, so I'll comment a bit here.
I have my convergence in the Yakovlev and the 109 set to 300 yards. I will almost never fire my cannon past D400, and I usually wait until a casual D200 to pull the trigger.

If someone is way out there, (D600, D800) I'll shoot my MG's to get him to turn. However, I will not waste my cannon ammo at these ranges.
At close ranges, I let loose everything.
Past that,
4 Hispanos is the best armament in game.
However, when we get the Me410 I believe the hizookas will be surpassed in total dominance by the Me410's dual Mk103s.
