We weighed the plane yesterday and now getting around to computing the
W&B computations.



While we pretty much followed the excellent spreadsheet I downloaded,
there was one thing we could not do.  Since we do not have a way of
fueling and de-fueling the plane easily, we cannot compute the arm for
the fuel tanks using the methods outlined in the spreadsheet.



Since our plane is pretty much in stock configuration, with the tank
size and location per plan, the CG for the fuel tank should be in a
known location.  Does anyone have the arm number for the fuel tanks for
STD fuselage, STD wing aircraft?



Also, what is the gross weight of standard wing aircraft?  The Velocity
web site has 2300lb as the suggested gross.  I have seen others quote
2400.  What is the generally accepted number for standard wing plane
with Franklin?



Incidentally, my plane tipped the scale at 1423lb.  A bit on the heavy
side compared to 1300lb factory quotes.



Hiroo
