datums(door post and the front of the top rail on the floats)It's a
question of how to do the math.Have to dig into the text books again I
guess.I left the battery unsecured till I know where I need to put
it.I'll be sure to do the mechanical test with the pipe to be sure.
Thanks

As I alluded to before Jason.. Call your MDRA inspector.. they seem
to have
an issue with no negative numbers in your W & B calculations. I guess
Alexander can't figure out subtraction.....
If that is the case.. use your nose wheel or the end of the float
deck as
your datum so everything is postive behind it. Be sure to get an
accurate
measurement to the center of the door post or leading edge for when
you
switch to conventional gear and to convert the Murphy 7.7 to 19.7
(or what
ever the current spelled out) WING range to reflect your datum.. IE:
your
empty C of G range is now gonna be MAM's numbers PLUS the distance
from the
leading edge to the nose wheel or float deck end.

OK, I'll just take Wayne's empirical data report here as [almost]
complete
vindication of the probable accuracy, propriety, virtue, brilliance,
etc.,
of my previously described measurement (spring gear axle center @
0.5"
forward of leading edge) and -- quite uncharacteristically -- say no
more.
And definitely, worry no more. ;-)

a hike
to and around 3979m (13,054 ft.) -- and lived to tell about it.
