Whether I use the MS tug, with an MS FSX-SE standard aircraft, or the pushback instruction built into my Majestic Dash oe PDMG 737, the pushback tug behaves strangely. On starting it moves smoothly. It's when it returns to the stand that the behaviour changes. Sometimes the tug returns to its start point before the pushback has completed (a/c still continues to move) but always it moves back erratically, like a 'crab, rather than in a straight line. Any ideas?
