The long awaited version 5.1 has been completed and will be available here later this week. Version 5.1 is a major update with higher resolution textures and much improved modeling, animations and effects. This will be a full download and not a patch, although it will be free of charge for all users that have purchased version 5.0.
It will fly in FSX!
Version 5.1 will be fully compatible with Microsoft Flight Simulator X (SP2 minimum), although some Prepar3D specific features such as dynamic lighting will not work in FSX.
An update patch for Draken 35OE to version 1.1 that will implement FSX compatibility will also be released shortly.
