Ted, that looks about ok.
Here's my drawing, I've taken your pic into ACAD and took into account the fuselage area, forward because it's obviously a MiG29 ;-).
The calculation is done in WinSchwer, if you want I can send you the file and also the program

Cheers,
RD

Thanks Ralf.

I guess it does look a little bit like a "29". I had not noticed that.

I have not heard of that program WinSchwer. Is it a CAD program?

Thanks again.

Ted

Ted, no, I've overlaid your sketch in AutoCad and imported the values into that CoG calc program... email follows.
Cheers,

due to multiple requests, here's the program... it's freeware and you can find various versions available on the net.
I always take the average between the two values given, so 12% stability. Worked extremely well everytime.
cheers,
