REFLECTOR: Questions b4 I cut the winglet

[mbuc]

I still have the dilemma of how to measure.  If I measure across the 
top, I am ok, but when I measure off of the bottom, It is past the TE. 

If I measure the 12 inches across the camber,  I am still in the foam, 
and if  I measure the bottom across the camber, it goes right to the 
trailing edge.

They look perfect the way they are!

My brain hurts.
