I have just reinstalled FS9 and have no Prop Wash Dust from the helicopters. I get dust that pops up when it crashes, but no"take off" or "landing" dust.Can anyone offer some suggestions?Also, in most of the helicopters I've downloaded, ie the Hughes 500,I have no spinning tail rotor.Any help?ATI Radeon 9800Win 2000 Pro NTFS Format1.5 Gig DDR RamThanksDarryl

FS9 has a differnt calling system for the engines and to get the tail rotors going you need to either tag it differently in the design program or add another engine entry to the general engine data section in the aircraft cfg. Like so.....[GeneralEngineData]engine_type=5 Engine.0=-0.833333, -20.0, 60.0engine.1 = -25.67, -0.44, 3.98On the effects, check you aircraft cfg in the effects section to make sure the naming is correct and it matches the effect.Regards, MichaelKDFWhttp://www.calvirair.com/mcpics/PBTMCa.jpgCalVirAir International VACougar Mountain Helicopters & Aviation[link:www.cgrmthelos.com]Cougar Mountain Helicopters
