Landing gear mounts:
Almost complete. Because the cannisters will make it difficult to access the landing gear nuts, I opted to attach some tee nuts to some hard maple in lieu of using nyloc nuts. Still need to relieve the center to make room for the center mounting bolt to the fuse sides. Had considered using the aluminum square stock and tapping threads in it, but the weight penalty was pretty steep. And I was concerned with a hard landing the force being directly applied to the center fuse mounting bolt versus the inherent flexibility currently built in to the design.
Cannister mounts:
Started gluing them in. With the header lengths, the can outlets will be just behind the end of the cowl. Because it is a tight fit, I am opting to help route cooling air around the front cannister mount through the lightening holes in the fuse. Instead of gluing balsa sheeting to the fuse sides to close off the tunnel, I am spacing the sheeting out with 1/4" square stock to help get an additional flow of air to the cans.
Fuse stiffening:
Adding some carbon fiber rod trussing to the bottom rear of the fuse to really stiffen it up. Will make it easier setting up the stab tube socket in the fuse as it won't flex once this is done. Thanks to my father-in-law for the old carbon arrow shafts. They will work great and nice and light. Going to use Hysol 9430 to glue in the carbon as that stuff really bonds well to the carbon. Will pre-prep and clean the shafts with acetone to help soften up the epoxy to help with bonding.
