Are fairings meant to create a massive aerodynamics forces from beyond the tip?

So this one has been bugging me for a lot recently as I try to get some of my older rockets working again.

I've noticed that fairings are creating a much larger sideways drag force than fuel tanks of the same diameter and length, and the drag force comes from well beyond the tip of the fairing when it should really come from the middle. I can solve it by sticking huge fins on my rockets but I prefer rockets without them. I've not been able to get any of my preferred launchers to fly without large fins on.

Is there any solution or workaround for this?

After further investigation, there are three bugs going on here.

1) The location of the body lift line before decoupling the fairing is incorrect. It's applying lift force too far ahead of the fairing (i.e. the overlay is correct).

- My StockBugFixes now contain the fix for this in ModuleProceduralFairingFix. (http://forum.kerbalspaceprogram.com/threads/97285)

2) The location of the cyan overlay line after decoupling the fairing is not correct. That is, it's showing the lift too far ahead, but that's an overlay problem. That's not a force position problem.

- Fix for this is to simply cycle the overlay after decoupling (I did not include this fix because it seemed wasteful to spend CPU cycles checking for and fixing the overlay).

3) The direction of the body lift after decoupling is incorrect. The overlay is showing the direction that lift is being applied, which is in an incorrect direction (i.e. the overlay direction is correct).

- This is not limited to the procedural fairings, but is actually a systemic problem in the body lift algorithms. You can replace the fairing with any part that's wider than it is tall (such as a SAS module, or FL-T100), and the incorrect direction of body lift results.

Thanks sal.  I'll use that fix. Hopefully this bug will be dealt with in 1.1.
