No one but the originator wanted it at 30%... I noted that you need much more power if its behind 27% than if its ahead... because behind is less stable and less safe.
I responded to your earlier comments:
"25 to 27% MAC of the moving surface is the ideal range for the pivot line" (post no. 2)
and:
"The number I was quoted for stability was 27%... not 25" (post no. 11)
I would not place it behind 25% at all. Not even 2% behind 25%.
