I have re-designed the top wing attachment to use two screws into the bottom of the top wing, instead of the pin as designed in the kit. I am using two wing servos in the bottom wing, and the upper ailerons will be driven by connecting rods. My outer wing struts will screw onto the sides of the tabs in the wings (similar to the kit). I did think about making the wing tabs go into pockets on the struts, but didn't want to add complexity.

I can't be certain from your description, but it seems that yours might be a modified original kit. If you are able to post some pictures that show the internal structure, those of us familiar with the plane might be able to tell more.
