Mark: Thanks for your reply; Yes I have studied this carefuly and have also read the help section of FSX; But my 727 doesn't like pushback turns...It pushes back only in straight  lines...That's why when I realized I had this problem I searched and found Rob Baredregts' Ground Handling gauge  which fixes this issue, But at the same time adds a very annoying brake sound. I began with this issue already in V2.2 of the 727 cap. I had all the posts in the forum,But I guess they got old and dusty and since have been deleted.

Knowing that my system struggles I just attemted again a pushback from the gate.
I loaded FSX with my default flight at the runway; Then I moved the Cessna to a gate with a tug,by choosing it via the options menu,Not by Slewing. Once ther I loaded the 727,loaded all the views and then Presses Shift+p inmediately fallowed by 1 or 2...The plane only began to move backwards...After a distance of aproximately the main gear and front gear it should beggin´to turn...?

It keeps on going straight backwards...? :-/

I have the same issue with my Super VC10
