Fabricated GMU25 stiffener mount plate. Cut avionics shelf angle.
Fabricated extended forward baggage floor. I decided to use the lower compartment to mount the GPS20A and the GAD27. My plan is to mount the ECU’s and the GEA24 behind the panel so I can run the wires along the top skin behind the forward baggage door brace to the engine.
My mock up. Not much room in an RV8 but this should work. I wanted my ECU’s in a relatively cool area with wire routing as separated as possible to negate any failure effecting the other system. Only took me 3 days to figure out the placement. I will probably relocate the avionics ground bus to the lower bulkhead. I’m sure I will change it another twenty times.
Spent yesterday planning and tracing avionics and switch cutout lines on panel.
Match drilled doubler plate to aft skin and bulkhead. Drilled doubler for antenna mount, dimpled, primed and riveted to skin. Riveted GMU and avionics shelves to fuselage longerons. Cut ELT coax to length.
Ready to rivet on the skin!
Installed nine more click bonds at various fuselage locations.
Primed and riveted avionics shelf. Installed ELT and transponder mounts.
