Well, even though we are about to be able to create new planes in il2 this is going to be a sticky subject for awhile yet. My opinion is to just wait and see what the AAA folks are going to say about it. They posted that new planes can now be inserted into il2 but nothing has come out yet, I'm guessing that the reason for this is they want to be extra careful that this goes smoothly without causing more controversial problems, just a guess though.

Is it possible to change weapon load outs? I dont want to anything unrealistic, but just more variety of combinations of the weapons the aircraft did carry but the game doesnt offer
For example, the late model lightnings had four hardpoints, two inboard, two outboard, but the game doesnt allow bombs or tanks fitted on the inboard racks if gunpods are fitted outboard, same with it wont allow tanks inboard, rockets outboard but does allow bombs inboard rockets outboard. :?
Thats just one example, as most know there are many more weapon mixes for aircraft missing. Some PTO allied aircraft had "field mods" for extra ammo, and this is missing on most aircraft in the game
With the possibility of new aircraft to come a weapons/FM change is inevitable. BUT, creating a new/modifying an old FM/DM for a new aircraft would not harm onlineplay IF the modded FM/DM is applied only to a new aircraft, and not an existing one. That way, only servers that actually have the extra aircraft in their planesets will allow users to play online with them.
