Thanks! Unfortunately it's going to remain a tech demo for now. It was my first attempt at making something substantial in 3d and I think I bit off more than I could chew. I can always come back to it now that I've learned a bit more about 3d but I'm working on something else for now.
I wanted the game to be more arcade style than simulation, but I think with some dampening like you said could make it require more skill and make it more fun to fly. I'm glad you like it, I think it's a fun little game for what it is.
