I hope I don't feel dumb when I hear the solution to this, But I am not able to add a drop tank to the 109. I can add tanks to the FW. When I do an arm and refuel sitting on the runway I only get a choice to add an SC250 or SC500 bomb. I tried offline writing a mission with an airstart that included the drop tank. When I launch the mission my plane doesn't have a drop tank.
What am I missing? I've searched forum and internet and manual. I dont' have a clue here....
