But this seems rather arbitrary and limiting. I wonder why only 5?
I have reviewed historical ladeplans that also allowed a variety of fuel configurations. Additionally, I have picked in-game load-outs where the fuel usage was a primary consideration.
5 does not seem enough to me to afford avoiding the unnecessary wastage of fuel -or- account for the added bomb load configurations in upgrades to AC models.
War Thunder allows 9 for the JU 88A-4 without even considering fuel or LMA,LMB mines!

I hope this is something that can eventually be expanded.
