RE: Phase 3 EF - 16
DUH ! I finally figured out the answer to my CG issue ....balance it upside down. The center of mass (weight) is above the center line (and wing) and affects the static balance. First time I tried it with my home made CG machine, it locked right in after moving the battery (very slightly) a couple of times. It balanced very near the front of the cheater holes using a 3S 2200mah 20C battery with the 64mm fan and 4500kv motor mounted at the 1 1/2" position. It flew a little twitchy in pitch so I need to move the battery a hair forward but, other than that it was pretty solid. The CG is pretty sensitive on my bird ....when I move the battery a little it makes a very noticeable difference in flight.
