Older 30% AW Edge C of G?
 

I have an older AW Edge 30% gasser. I run a 3.2 Brison. I bought the plane used from my father and he bought it used from another friend. There is no manual for it so I would like to know where the factory C of G is. Can I figure this out somehow? Is it directly beneath the wing tube?

What I typically do for first flights is measure the wing tip, from the leading edge to the aileron's trailing edge, and set my CG at 28% - 30% of that measurement. I use the same percentages whether it's a straight leading edge like the Edge or tapered. I usually end up at 32% or 33%. Some people's default approach is to start out with the CG at the front of the plane's wing tube and then adjust per personal preference.
