I've been asking for Me 262 ordnance upgrades for some time.

For instance, unless it was a subvariant with a bombing computer, I think they could install all of the nose guns. Usually, you'd have two removed for weight, etc. And the latter is the default with no options for otherwise.

The Stormbird could carry cluster bombs, and I think it could also carry lighter bombs than the default on the forward racks. I really would like to see more options there in the future. Apparently, because the '262 was so fast, cluster bombs were in fact the preferred weapon, and the latter are not currently available.

The variant I liked was the recon variant with only a single Mk-108 cannon!

The game could definitely do with a bit of a revision when it comes to axis bombs (as mentioned - ability to carry less bombs on the Ar-234, and an ability to carry gunpods or more variations for the Bf-109Z)... I really enjoyed the mods I made to do that.
