When posting in this forum, please specify which version of Draken you are referring to, and also which versions of FSX and Windows you are using. Additional info about your hardware and any other addons you are using might also be helpful. You can also add the specs of your setup in your signature.
Please give your topic a descriptive title such as “Contrails not visible” or “No sound in exterior view”. Topics with titles such as “Help me” will get a low priority.
Do not yell in the forum. Using CAPS LOCK or exclamation signs in the titles or in the posts will not get you more attention, rather the opposite.
