First of all Thanks for help.
My CG is 4.5 inches behind leading edge, someone said it should be 2.5, I think.

Checked landing gear (how mounted). Per plans. Sit slightly behind CG per plans to help nose fall forward.

I do have room to move motor LA 46 forward, possibly where rear bolts could be moved to front bolts, then add new front bolt holes. There may be a possibility I mounted motor to far back to begin with. But dont think so.

Had foam core wings made fully sheeted, but does not feel heavy, but do not have scales available at the moment. Covered with dope/med silkspan, 2 coats, lightly sanded. Primered once, sanded/filled, sanded then painted white Rustoleum lacquer. Just enough to cover.

Fuse is dope/silkspan medium. same as wing procedure.

Other things 2" Great Planes spinner 12/5 Rev Up prop, not APC like first said. Light foam wheels Tom Morris. Ball links carbon shaft.
All light quality stuff. Its possible I mounted motor wrong, to far backward.

Thing is a plane anchor

It seems the odd ball in the equation is the foam wing which tends to be heavier(a little or a lot, depending on technique)than built up wings. Most of the wing weight would seem to be behind the CG so, viola, a tail heavy airplane.
Move the engine forward. If still tail heavy, add lead as far forward as you can get it until the CG is close. You should have lots of power available to fly it even if overweight. The LA 46 pulls my 55 oz Skylark of similar size, though less drag, like it is a featherweight.
