Just wondering how you are "supposed" to measure CG. Its funy, I have been building and flying for 13 years, and I never actually found out. My question relates to using a flexible tape that measures from the leading edge following the curvature of the airfoil, vs. my top down method of laying a rigid tape or ruler flat against it and measuring there. Thus far my CG's have always been fine, but my latest model has a VERY short range and a thick foil.

Thanks in advance,
Brett
