| Subject: | Center-of-Gravity for Mark 3 |
I just completed the weight-and-balance for my newly rebuilt Mark3 (see
attached file). I don=99t have a manual for this plane. Can
anyone tell me what the acceptable center-of-gravity range is for a Mk3
(as a distance from the leading edge)? Per my calculations, I=99m
getting numbers that show a substantially aft center-of-gravity. I=99
m getting, depending on loading condition COG ranging from 21.94=9D
to 29.34=9D. One entry on the matronics website indicate that
the range should be from 16.5=9D to 23.1=9D from the leading
edge???
Thanks for your help,
Dee LeBlanc

According to the original manual, the cg is determined as a percentage of the chord,
rather than a specific number of inches.

Go to page 40 on the link, it is on 3 pages total, 40-43.
Looking at your figures, I realize that my answer is not exactly what you need,
sort of an apples and oranges thing - here is how I did mine using the manual;
see attachment.
Hope this helps.

The range I use for my MkIII is:
Aft CG Limit is 23.1" or 35% of wing chord
Forward CG Limit is 16.5" or 25% of wing chord
