I was always having trouble balancing my large planes. It seemed I needed two people to assist me. They would have to crawl under the wing and hold up the plane. It wasn't very accurate and I wanted something I could use by myself.
Here's the simple CG Balancer for large scale planes that I came up with.
Place under plane and push down. Lets you lift plane from ground, rather than having to lift plane by hand and set it on something.
I used 1/2" aluminum rod, but you can use a pipe and "T" rig also. Works great.
I will have some pictures from the Horizon Aerotow ready for the next issue. I will include some "how it works" photos.
