Jim, there is an even easier way, cut a slot about 1/2 in by 1/8 in at the trailing edge of the wing, cut a slot in line with the push rod ,without the clevis or balljoint,push the pushrod forward to shorten the slot.
This slot will be about 3/16 in by 1 1/2 in long.

Put the horn in the wing slot and slide it back to the rear of the slot at the trailing edge,then slide the wing into the fuse,align and glue.
The horn and its parts can now be slid forward and inserted into the rear of the wing and reinforced with a fiberglass wrap.

The fillets will cover the slots at the trailing edge and you only have the patch the slot for the push rod.

Build the fuselage in two sections, a front section which slips over the wing from the front, and a rear section which slips over from the rear.  If you think about it, the structure and function of the front and rear of the fuselage are rather different and no reason to make the whole fuselage in one piece.

The main  reason to make  and  keep the fuse in 1  piece  is  for  alignment. When you make  a  2  piece  fuse  it can get glued together at an off angle. and  many times  does.

It is  just much more bullet proof  to keep it 1 piece.
Todays  laser cutting  would help a  lot  but you still have  a better chance to get one half off a little
