ok, so here we go, this is my very first home made plane
...
The measure are in milimeters
And here is my results... It's that I just don't know what's what
The red circle shows you input a Static Margin of 10%. It shows in the green circle that the CG for that SM would be 7.26 back from the LE of the wing.
The CG range is usually from a SM of 10% to 15% for just flying around safely. If you reinput the measurements into that geistware and ask for 15%, you'll see the other location for the range where the CG will be safe.
It will be safe to fly an airplane with the measurements you input with the CG somewhere from 7.26 to wherever the 15% input gives for that input.
