Moved some things around. Rudder servo pull pull aft, Elev servo aft (single), radio & 4.8 bat aft, (FWIW TE prop is 8" fwd of supplied ply motor mount. Ended up with about 3/4 oz lead near TE hor stab.

If I were doing it again, probably alum standoffs instead of engine mount pictured. I'm still learning and the plane needs 6V bat which would more than offset the small lead added.

Plane balances to midpoint of suggested CG.

tkg: On the G23, could you give us an idea of distance forward of firewall to the prop? I just centered the engine on the supplied mount.
