C of G position
OK
C of G is 1 3/4" ahead of the front edge fo the wing spar slot in the side of the fuse. Or 9 5/8" back from the leading edge of the wing at the root.
If you using the original wings, the main engine former has to be in the correct location because the spar retainers are attached to it. BTW, the spar retainers should be attached to the back of the former and not the front.
If you need anything else, let me know before I put all back in the box.
