Agree Vatikus... This is a simulation... We paid good money for the module, so I want the whole airplane. This is the closest I will ever get to flying an FW190, and DCS is renowned for study sim level products, so it should be as close to right as possible. In the field, as you obviously know, the Luftwaffe was constantly reconfiguring the FW190 to fit all sorts of missions and pilot preferences. These configurations ranged from simply changing the arrangement of the guns (or removing them all together) to adding armor, to using a different propeller (of which there are three types used on the A8 if my understanding is correct). Lots of other little field mods as well.
Unlike others, I have found the 190 to be a passable PvP aircraft. I would like to have the ability to customize my loadouts like the actual Luftwaffe pilots could and did so that I can be better equipped for certain missions or even play styles. And I like to play offline, so I want to have the ability to armor up and go B-17 busting.
