Plans show between the front egde and rear edge of the main spar. About 3 3/4 inches puts it in the middle of the CG. Instructions say to refer to plan for location.. Not listed in assm. manual.

Hi, the plans for the Goldberg Cub show the CG being in the middle of the main spar with a range of approx. +/-.25in.
Just an FYI, the instruction book refers to the plans for the CG.
As for a 40 size engine, I cant reccommend it. When I built mine many years ago I initailly used a 40. I was less than impressed with the setup and ended up getting a bigger engine. IMO stick with the 65.
Cheers.
