I just ordered a dual battery kit for my Phantom. http://www.flying-hobby.com/phantom-dua ... 12000.html I haven't received it yet, but I was looking at the pictures and began wondering if the position of the batteries will affect the the lift from the propellers. Will the thrust be be dissipated by the batteries hanging on the outside of the copter? I'm obviously not an engineer and may be fretting over nothing. Has anyone else had first hand experience with these mounts and their affect on lift?
