The composites that came with the kit have been quite a challenge. Miss-shaped and and some times a little damaged (see my post on a wing tip) I have become accustomed to heating and shaping along with some filing to get the proper fit. I sent a lot of time fitting, removing, heating, (repeat) to get a fitment I could use to final rivet. The canopy composite seems to come with pilot holes..... Do Not Use them. I thought they were a guide but it turns out not to be the case. Fit with straps and use the fuselage rivets and center measurements as your guides. The newer manuals have more photos to help with alignment. The rivet hole finder is your best friend in this procedure. I found it easier to epoxy the spacing strap, firewall, and cowling attachment together so that there was not metal straps flopping around. After aligning the metal pieces the holes were up-sized to 4.0 mm (5/32) with a reaming bit. These bits are really nice because of how smooth they leave the hole. I had one particularity badly shaped corner that I managed to get into reasonable fit. Holes were counter sunk and generous amounts of Sika was applied
