I removed the fairing and drilled out the holes in the fuselage to .193" for the M3 rivnuts. I then installed all of the rivnuts.
During install my drill operated rivnut to snapped the M3 arbor. I have put a lot of rivnuts in with this tool and it was getting beat up a bit so I wasn't that surprised. I had bought a manual tool for another purpose not too long a go, and while it was a bit slower and more awkward, it got the job done and has the advantage of being able to feel when the rivnut is set rather than worring about what torque setting to use.
