Aerodynamics issue with my plane?

[GKSP]

Hi forum members!  I have recently made an Airbus A320 for fun, but whenever I take off or use pitch control, my plane always banks gradually left.

The craft file is here.

Feel free to respond with feedback, comments, or anything regarding this.

A few questions to help us;

Any mods used?

Did you attach everything with symetry?

If you have used struts, have you checked on the runway that they are all where they should be? Sometimes one half of a symetrical pair will decide to either fail to attach, or attach somewhere else. Same for fuel lines.

It seems to work just fine for me. Do you fly with SAS on?

Yeah, the top-front strut on the starboard wing is missing.

To everyone:  thanks for the info about the symmetry and struts.  I did fly with SAS on, and I will get a screenshot up probably in a few hours!  Thanks, bewing for finding that strut.

The mods I have are:  Mechjeb, KAX, BDA, kerbal konstructs, and TakeCommand.  No mod parts are on the plane.
