Thanks for the great product.I really hope you can fix this problem started from you made the quick edit pushback.
The problem doesn't have anything to do with the Quick Pushback or the today's update, and it's a result of a change made several weeks ago, to fix lots of other problems users reported of the pushback truck making a 180 around the nosegear, on some airports with some airplanes. This has the side effect of enlarging the curve radius in other airports/airplanes.
That's the whole point of having the quick pushback to begin with: so you don't have to rely on an automatic system, which will never work in all sceneries out there, most of them with plenty of errors so, you should try that, and keep in mind the latest Quick pushback used is automatically saved and can be recalled without entering the quick edit mode again. The main advantage of the new custom pushback, is that you are no longer limited by issues/bugs/quirks in the underlying AFCAD.
In any case, it would be useful if you could make an example, possibly using a default airplane with a default scenery or an FSDT scenery, of an automatic Left/Right pushback that worked best before, since we might tweak the automatic system again.
