KR> KR2S Wing sweep question.

[Pete]

I was working with the CAD drawings I've done in Rhino for the KR2S and 
I noticed that the outer wing according to plans has a minute amount of 
forward sweep. I wonder if this has anything to do with the very 
sensitive aft CG issues the plane experiences?
Can anyone else confirm or debunk this discovery?
Cheers.
