I was hoping some one would bring that up :) For a while a thought maybe that was a good diagnosis for what I have been seeing, however sean kind of opened my eyes to turbulance on my little range there.

I have a new buddy at work who invited me to come fly my big nitro rc helicopters on his acreage when it warms up, kind of wanting to throw in the idea of shooting too, maybe I can eliminate the turbulance variable and see what pure wind does.
