Well, part of it is 3 holes where I shot it with my son's BB rifle. It was way up in the pine tree and I had to use binoculars to see it. It was behind so many branches and wedged in tight. Being a pine, there are no leaves to lose in the Fall, so I thought it was up there for good. They all thought I missed with the rifle, but I knew I had to hit it a least a few times in the 10 shots I took. I'm an Expert marksman. I couldn't see it without the binoculars while I was taking the shots, but I still knew exactly where it was. My son was the first one to see the BB holes after my wife recovered it.

I was thinking tonight that I might make a C channel out of it. I fly C and my son's planes are B. My red C has a Rx motor out problem. That makes 2 for me. This one went while it was flying. So, I may as well turn this into a C so my son and I will still each have 2 planes.
The lower wing is attached to the bottom of the upper wing with an overlap of 1/2". Double sided clear tape between the wings holds the entire seam, and short pieces of single sided clear tape reinforces the leading and trailing edges. I was going to attach them properly if this test configuration worked, but it worked so good that I didn't want to mess with it. The plane flies great. Smooth turns, stable, a real treat to fly.

I don't have any problem understanding your CG Finder drawings. Hey, I work on a CAD system every day, and I still do that type of drawing occasionally.

BTW, it wasn't as wet as I thought. It dried out already and I had to try it. It still works.
