Rivnuts

I'm trying to work through the fuselage more or less sequentially, so one of the first QB jobs is a whole bunch of rivnuts.

I'd put all these ones in with Loctite 277 threadlocker, however some builders are using JB Weld, and I note newer (late 2022) revisions of the manual suggest steel epoxy for rivnuts elsewhere.

Rudder Pedals

Next up are the rudder pedal mounting brackets and pedals themselves. These are fairly straightforward although the bushings have tight tolerances and I am considering sanding them down a little bit as there is minimal resistance to pedal movement with them clecoed in place.

Engine mount permanent installation

The factory temporarily mounts the engine mount to the firewall for transport, so these bolts need to be swapped out. My aircraft will have a parachute, so this is where the front cables attach too. Unfortunately the supplied AN5-7A bolts are too short to pass through the parachute cable tang as well, so they are swapped out for -11A bolts.

Mount is under tension so needs creative strapping to keep it aligned with the firewall holes.

Always good to have help with these tricky jobs.

Most builders seem to reverse the installation so the nut is on the external side of the firewall so that it can be seen post-installation of the upper canopy fibreglass piece, which makes sense so I have done the same.

Cowling mount and reinforcement strip

This is a bit tricky to get in on the quick-build as the side skins are riveted on throughout their length, however the reinforcing strips can be snuck in between the skin and firewall with a bit of patience.

Very similar between left and right so keep careful track.
