Exactly 49% !  Now, how that 49% is calculated is not grey - it's
non-existent!  You take your best guess at the total labor that would be
involved in the original kit or plans and then deduct the estimated =
labor to
build the parts you bought. You, the builder, are supposed to have =
invested
51% of the effort. =20

However, this isn't even the way the FAA does it - because many guys =
spend
half their building hours on the finish and not on the airframe. So, =
under
my little scenario above you could buy a completed RV-x and then spend =
700
or so hours painting it and making it look pretty and claim you built =
51%
based on hours alone! =20

Take your best guess!
