I did a little experiment and was taxiing Flight One's ATR with no winds and it was very steady. My taxi direction was 320.I added about 10 knots of wind comming from 295 and I noticed the ATR would careen and require constant correction.My question is since this A/C weighs over 45,000 pounds with passengers and fuel, how in the world can a 10 knot wind from any direction cause any taxi correction?? Or is the CH Products rudders that are out of callibration? Can some one with the Flight One ATR and the CH Products Rudders try this experiment?Can we assume the the wind physics of FS 2004 are out of wack?Thanks!Barry

Yes, it 's the physics. Use FSUIPC registered version to fix.Allcott

How should I do to let FSUIPC take care of this issue?
