Not really anymore with the revised location.

JohnVH, you are correct. Its from the center of the tube. I was wrong.

People freaked when this plane came out because they were having to add so much weight to the nose to get it in the range.
I have a friend who got his early in the first run. Put a ZDZ 80 twin in it and was way behind the tube for CG. What did he do? He went out and flew it. Flew fine for him there. Matter of fact he felt it needed to go further back.
A few months later Horizon revised the CG location to just about where he was.

You can fly these planes at a much wider CG range than people think.
