MA setting is 2.0 In the ETO map you can go from London to Essen, (48 to 30) with 100% fuel, but that is it.
Fuel will be set to 1.5 which will give you about 1/3 more range, (a bit more realistic with the scale of the ETO map). With drop tanks you should be able to fly into Germany a ways and home again.
I would strongly suggest anyone who is going to fly across the channel take drop tanks.
