Okay, guys. Here's the "Exhaust System Install" progress. Made the canister cradle from edge-grain balsa, laminated in ply, lined with silicon pad, then epoxied to the wing center section, bottom. It is shown with the KS canister laying on it, and will be secured using O-rings (on order) that will go from screw, over canister, then onto other screw. Done this in the past, and works well. The cradle weighs 4 grams.

When I get the header, I'll assemble the whole thing, coupler, pipe inlet extension, and everything and do pics.
