Q1_Aircraft: Q1 C of G

Hi I was wondering if anyone could help me? I am working on a Q1 and I
want to know if the center of gravity of the aircraft is determend
when the tail is raised to flight attitude or parked with 3 wheels on
the ground? Or How many inches arm min and max in either position?
Thank you in advance.. Marvin

Yup,

raise the tail until the firewall is vertical.

I will look in the handbook for the numbers if someone does not beat
me to it. This C of G range (0.75')is absolutely critical. I have
flown the aircraft once on the forward limit and it was one of my
least pleasant aviation experiences, consider it in the same light
as 'practice bleeding'

Regards

John

0.75 inches seems too small
maybe about 3'

Marvin,

Static CG is measured with the tail on the ground and is for ground
handling. Aerodynamic CG is when in the flying attitude. You need to
know both.
