For cylindrical vehicles, aerodynamic force should not be dependent on roll. However, with FAR (haven't tried with stock), the reported AerodynamicForce depends on the roll of the vehicle. (note that gravity is hacked in this clip).

I think that this is being caused by the way that the lift vector direction is calculated, using the cross product of the vehicle right vector and the velocity. This is appropriate under most conditions for aircraft, but does not work for cylindrical vehicles.
