S-wing drag

[miklkit]

I've been noticing that the S-wing has more drag than other wings so went to the Wiki to find out how much more.  It turns out that all wings have a drag of 0.02.  This is incorrect.  Is there a source that lists the proper drag values?

Look at the delta.cfg link in the infobox to the right of the wiki page and it'll tell you more.  The maximum and minimum drag values in the file are .02, but there's an angular drag value of 2, and a value for drag that varies with the angle of attack between 0 and .6 in ModuleLiftingSurface.

Whether those figures mean anything to you is another matter.  If that's not what you want, then you might be best off looking at modder resources:  modders who make wing parts need to make their wings perform predictably in concert with KSP stock wings, so seeing what they're using to do that (and how they're comparing their parts to stock parts) might be of help.  The mods themselves might also be instructive:  B9 Procedural Wings comes to mind as one that not only properly has to account for drag, but must do so on the fly, to coin a pun.

Good luck!

Ah, I did not know that the .cfg was readable there.    Yes the drag at maxangleofattack is twice that of the standard wings, so that adds drag.  There is also an entry that says all the wings I looked at use an internal drag model.  Look into modders stuff?  That is way above my pay grade. 

So I'm back to flying one plane where the only difference is the wings and trying to find any difference in performance.  So far the difference is 2 high drag wings vs 10 low drag wings to get about the same lift.  The s-wing might be the winner here.
