Back to the wings.
Tonight I laid out the aileron and servo locations on the wings.
I use a plywood template and bend copper wire that I put in my solder gun to cut out the foam.
the last two pictures show the "tunnel" for the servo wire. After I melt the tunnel out I back fill the slot in surface of the wing
with sheet balsa sanded down to fit the slot.

The 1/4 x 1/2 servo rails have been expoxied in place. I will back fill extended sides with scrap foam, give the wings a light sanding and they will be ready to be sheeted this weekend
