I used 8 clips total so far. I think that should do it. My brother Steve gave me one of his extra clips a while back as a model. Even though I have 11 extra clips of my own I decided to use his as one of my 8 used. Sort of a tribute to him. It will be a conversation piece.
I used 4 clips in the aft section at locations where you rivet the longeron to the bottom side skin. Using these locations allows you to rivet them on now before the top skin and gives you better access to rivet.
I used 3 clips in the cabin area where the canopy decks will cover them.
One more clip just 1 hole forward of the instrument panel. It’s one hole forward of that vertical line of 4 holes in the side skin.
