While HTC doesn't publically anounce what their sources were for modelling any particular plane, it's rather obvious that our in-game "190A-5" matches perfectly the chart of a captured, repaired, and modified 190G-3 which stands apart distinctly from the speed and power charts of 190A-5s.
We've updated the "109G-10" to reflect its proper name... It was always based onthe K-4, and now it is a K-4. Let's do the same here. Rename the A-5 to the G-3.
Remove the cowl guns (the flight test simply added weight ballast where they were, assuming that would make it an A-5, which it didn't), remove the outboard MG/FF (190Gs did not carry this), reduce the inboard MG151/20 to 150 rounds per gun (a weight savings measure).
The 190G series was the long-distance bomber. It could carry the following loadouts:
Centerline:
drop tank
500kg bomb
250kg bomb
4x50kg
Wing pylons:
2 DTs
2 250kg bombs
2x 20mm gunpods with 250 rpg (for both ground attack and bomber hunting) -- probably won't see this in-game though
What we have is not a true 190A-5, so let's name it what it is truly modeled after, and add the loadout options.
Then we open up the path for a true 190A-5 later on. The modeling is already done. The power curves and the speeds all match up to a 190G-3. Let's just make it a G-3!
