Fuel tank mounts are installed. I used Medium “Purple” CA to attaché the rails. There are plywood doubler pieces that slide over the Rail “U” shapes then you glue the rail into the router grooves on the inside of the fuse wall. The plywood doublers are then glued up tight against the fuse side. This makes a strong and lightweight tank mounting system. The laser cutting on these parts was excellent and they fit tight but no extra sanding or fitting was required on mine. If your needs a little sanding its no big deal just clean up the edges a bit and it will all fit nicely.

Some minor force was needed to get the rails into place. The technique I use was to align one side then pivot the rail into place straight down from the canopy opening. If you tried to plant one side then slide it in at a angle say front to back horizontally you could break the rail assembly apart. Coming straight down kept everything together. Only a small amount of force was needed to spread the fuse sides as the rail pops into place
