Here is the finished core, the root section, the tip section and the core placed over the plan

Knowing Chris, I can imagine that has been keeping him awake at night with worry

I was keeping my involvement in this project quiet as I know I have a tendency to cause Jon to roll his eyes!

That's pretty neat Mike

Although originally planning on a sparless wing, it had been pointed out that the aileron and flap servo bays create a weak point and have decided to add a spar just in case. I tried cutting slots for the spar caps but could not get consistent results using the hot wire. So have decided to cut a vertical slice out of the wing and then rejoin it with a pre-made spar. I've gone for 1/4 x 3/16 caps and 3/16 balsa shear web which is drying overnight.

I cut the wings in half and re-joined them with the spar in place. A light pass with the sanding block levelled them with the foam (protected with masking tape.
Then cut out the servo bays prior to sheeting. I'll keep the foam blocks and cut a slice to line the floor of the bays later.
Then cut a slot for the servo wires.

That wing isn't failing Mike!
