This little heli is very sensative to even small changes in weight distribution. The CF rod absolutly changed the CG enough that the heli was effected.

Just some more stuff I learned this weekend

Right on Bob! The CoG is a MAJOR factor in the performance department with this heli... I have been experimenting with this alternate battery location for just that reason; you would be surprised at the difference it makes with respect to rolls and flips. This raises the center of mass by roughly 15% (rough estimate) but can only be done if the boom has been extended; otherwise it brings the CoG too far forward.
