I hate to say it but at 23gms already for only about half the model for a 25cm span you may as well stop right now. That's far too heavy to fly well at all. An acceptable weight for just the fuselage and prop for this size would be about half that weight even for casual front yard sport flying.

You're going to need to find ways to use less material. For example I see that you're still using a motor tube and wrapping a fuselage around that tube. That's a lot of extra material to achieve what is basically a doubling up of the construction. Perhaps work on forming the outer skin into a U shape with a glued in top cap so it can be stiff enough to accept the rubber loading on it's own.

Even just making the tabs on the formers smaller would be a good step in the right direction.
