I found a month ago an Excel file (chart) on this forum. But I can't find it anymore. I don't remember if it was a post attachement or an external link.
It was a grid, comparing Wing area and airplane weight. By looking at this chart you can see if you had something, light, normal, on the heavy side or not flyable.

Someone know where I can find this file?
Looks like the file I attach to this post, but in Excel.

Thanks.

Nice chart don’t know where to find it but I would love to have this as a reference
I usually know where to start any way but it would be great to just check things quickly
If you find it could you post it on this thread ill post any info I can find also

That's a slick chart. I've seen it before years ago.

It seems pretty close to being on the money too. Other than the "Trainer" band should also include lightweight 3D models.
