For the rear deck, push it up against the canopy deck and draw a mark for the location. Remove the canopy deck and glue on the rear deck. I used wood glue on the inside and some CA on the outside edge. I started with one side, pushed down and aligned the side with the fuselage side. THen I put CA on the other outside edge (the deck will lift up a little on the other side to get the glue in. Then press that side down so its aligned with the fuselage side. Finally glue the front and rear ply formers in place and then put balsa sheeting across the front of hte deck.
