This update finally makes Chaff useful and can be used to jam the Shilka's tracking radar. I've actually now also completed the whole jamming system so it is possible to simulate not just countermeasures like chaff and flares but also things like the "Disco Light" AN/ALQ-144 IR Jammer that is present on a lot of helicopters. 1. Chaff can now jam the Shilka's tracking Radar. It is reasonably effective but it may take several dispenses to fully jam the Shilka. Chaff's jamming ability is very short lived so it is quite possible for a jammed shilka to re-acquire you again pretty quickly. 2. Chaff now makes a noise when dispensed. 3. The Kiowa now has its "Hero" external model. 4. The Kiowa now has water interaction settings. 5. Tweaked the Kiowa's drag and lift settings so it can now obtain a reasonable forward speed when fully loaded.
