Stems,I'm not sure if this is related to your problem or not but the default DC-3 gave me fits for a long time to the point I couldn't fly it. I couldn't land it. When I would flare the airplane it would just drift off the runway before touchdown, this happened no matter what I did.Somewhere down the line I replaced the aircraft's cfg. I copied out the cfg with the repaints and installed the original cfg. from the disc. That solved the problem. I then copied the added texture entries back in and I was set to go.I have no idea what part of the cfg got corrupted or how or why it happened.

I think Peter is right I set the Taxi Wind to automatic in FSUIPC and things improved and now I can roll and land much better. I am no Pilot but I can understand very well what Peter was saying altough I never immagined that the effect is so drastic on an A/C such as A320 or B737. I do not remeber having this in FS2002. If the problem was a wrong allocated key or button then would mean that the A/C will always go to the same side but in my case the nose always turned towards the wind direction whether it is from the left or right. I was testing with 16Knots winds, now I can take of and land with the same settings.
