easyfly sim ?
as I can't fly 3D at all can't help much with that aspect.. but there were some good downloadable planes from william rohner or whatever his name is.. but the links to his site keep getting messed up cause he's moved it a couple times. I'll see if I can find the link from home and maybe post a few of the planes that I've already downloaded... as there was a NICE trainer and a good Stik style plane as well..
