Model Forum / Radio Controlled / Air Models / June 2004

I have a Pitts Special that I have inherited but I don't know what the C of
G is for it.  This model has an 79.5" upper wing span and is approximately a
40% scale model.  It is a very well done in the Holiday Inn Aerobatic Team
colors.  It was built from plans but I don't know who drew up the plans and
I can no longer ask.  I would hate to damage it so I would rather not rely
on my calculations alone.  Since the Pitts Special has both staggered wings,
and a swept back upper, but straight lower wing, I would like to compare my
calculations to what others have.  I figured that the C of G should be at
55.9% of the upper wing (measured from the leading edge at the root).

Can anyone give me the C of G they have for their Pitts Special models,
expressed in a percentage of the upper wing cord, measured at the root?  I
figure that as long as your models are built to scale I should be able to
translate your measurements to my model.  At the very least maybe it will
verify my calculations.
