I noticed this for a while but it actually seemed to vanish the more refined my start up procedures got (That or I got used to getting rid of it!)
Not to sound patronizing, but have you turned all the SAS controls on? Is your fuel spread even? Are you in freeflight with wind at 0 and are you setting Take off Trim? If so you'll need to trim it out once you're airborn. Infact you'll be trimming a lot of the time, not as much as a chopper, but a lot! Also as stated above, your weapon load out is fine? Try going in with totally empty stores, sidewinders and all.
Aside from that I'm not sure. I did notice that exact same lazy list to the right but the more experience I had with the plane, the more it seemed to vanish. Now i'm not sure if I just automatically correct for it.
