Had searched this complete thread for COG measurement & couldn't locate it. I followed the 30% rule from the leading edge (7.5cm) to get the battery in place. I was looking on RC groups for colour scheme ideas when I noticed somebody suggest 2.5cm, that equates to 10%. I have checked my Eflite Extra 300 3D indoor flier & COG marking is sitting at approx 30% and flies stable. Can someone clear this up for me please?
