I think someone said it before, but the game will search for the folders for these planes as long as it has the entries in the files in the STD folder, and crash if it does not find the folders they relate to, so no go with just adding the - to the folders. maybe if you had a seperate copy of the STD folder to copy into the mods folder for when you want to disable these aircraft, as well as the original... i could email you a copy with these alterations made?

As to the default skins it sounds like you have it sorted already? is the new fb_3do20.SFS file a part of a skins mod you use? as i said i have never needed to change it. Also there is in the unified installer a default skins mod with a folder for each aircraft - presumably just copy the skin you want into the appropriate folder (this i haven't tried yet)
