Oh no worries - you are helping! I want to get this right and I've never created a MP scenario before.
I don't think you should send the money - that is a balance flaw - the intention is for the Luftwaffe to have to ground or at least not build more aircraft if the Allied attacks on industry are successful (because they start selling happiness improvements if they don't have a positive cashflow, and all of their aircraft are "attack" meaning that they upset the population regardless of where they are). If you transfer money, things aren't working as intended. How much is your overflow at this point, roughly (I don't think it's giving anything useful away to me to know how much $ you have given that I've only hit one target that affects it).
Also - one issue with the plan of giving flak to the Luftwaffe - your aircraft are going to to get stuck on these flak units if you fly into them, because they will be carriers... Acceptable trade off? I would have a house rule that aircraft aren't to do that, and I figure any mistakes will only hurt the Luftwaffe as they will likely come when they're trying to intercept something, so I can live with it if you can.
