Could someone explain the basics of CG placement? I've head about calculating the MAC based of wing cord and sweep but still don't "get" the effect that different % would have on flight performance. For example, I have heard (perhaps falsely) that moving the CG back makes the plane more aerobatic/less stable. I have a heavily modified BUSA Eindecker on which I've moved the wing forward into the scale location. Can I still used the balance point indicated on the plans?
