Problem with vertical surface force

[kez]

I am trying to create a realistic flight model and I'm currently stuck on trying to edit the horizontal and vertical surface forces so that the plane has a somewhat realistic turn rate, but when the aircraft is banked even slightly, it tends to start "falling" towards the direction it is banked in ragardless of the amount of thrust the plane is given. The plane also seems to wobble really bad when rolling, which at first I thought was a problem with the center of mass being off, but the problem persisted after centering the model in both milkshape and by code. I also tried lowering the lift but that doesn't work either. This problem is very annoying and is kind of hard to explain so heres a video showing whats wrong.

I've experimented with surface forces above 2.0 and while they solve the problem, they're not really the desired results I'm looking for (aircraft has too much friction and turns too tightly) I currently have vertical surface force to 0.60 (editing horizontal surface force apparently has NO EFFECT at all. I've tried ridiculously high and low values with no luck) Has anyone else stumbled across this issue or knows whats really happening here?

heres the code

If you're experiencing side-slip you need to increase the vertical surface force.
