I just got done moving the battery behind the servo's, I went to check the c.g. of the plane and if I try to check it right side up, going off of what the manual says and using the main wing spar as the c.g. point the plane is tail heavy, but if I check the c.g. with the plane inverted on the same spar, the c.g. is perfect. It sits nice and parallel with the ground. What do you guys think?
