I used that COG calc yesterderday and wasnt sure of the measurements;
i used these figures
tip cord - 200mm (7.9inch)
root cord - 350mm - (13.8inch)
Span - 1400mm - (55.1inch)
Sweep (distance)- 457mm - (18inch)
COG Result - 264mm - (10.41inch)
I'm entering the figures in Inches.....Is that correct?
What have i missed???
The sweep back you entered is the dimention for the 2m span version and the other dimentions are for the 1.4m span version
It should look like the file below for the 1.4m set of cores
And like this for the 2m version
