I'm wondering if there's a mono-builder out there who has data from his (or her?)
C of G calculations which would reveal how much the C of G shifts as a consequence
of finish painting?
In other words, I'm wondering if I have an otherwise complete aircraft in primer
and do a preliminary C of G calculation, how much of a shift should I estimate
will occur when painting is complete?

Dave, Did you use NAS 517-2-9 screws for CS08, if so I will take your
earlier advice and order -8,-9 and -10.
This blow by blow of yours is great, it needs putting together in a 'how
to' to supplement Mod 78.
I also bought a remote camera, as well as being helpful it showed me how
much I need to clean up before I fly.

I'm not convinced of that, since the paint density is constant throughout an
d the moment arm is much much longer for the paint on the fin than on the co
wls.
I would expect the cg to move rearward slightly....how much I'd have no idea
.
Cheers,
Pete
