Rerouted the transponder wire thru the corrugated tubing. May be a little short now. Secured the ELT speaker to the lower F-707 bulkhead. Added several more wire tie downs to the aft fuselage. Swapped out the silver screws on the ELT remote control on the panel with some new 4-40 screws and used a sharpie to blacken the head. Haven't been able to find black 4-40 screws.
