After practicing sculpture, I decided to get into animation and run into a problem. I started practicing animation, but I have a problem. I chose the bones for this exercise. The exercise was to make a turn of paper and I wanted it to fly, to do it in other ways, but I had never done it before with bones. At the time of trying to fly, the plane is deformed very ugly. Any idea how to fix it?
You can join all your bones to make a unique armature (ctrl J) or recreate your armature from scratch. In both cases it's better to create an additional big bone which won't have any weight on the mesh but will be the parent of all your bones. To do that you will have to select all your bones, then, at last, the parent bone you have created and ctrl P > Keep Offset. You also have to control that the influence of your bones on the mesh is correct, either in Weight Paint mode, or with Vertex Groups assignments.
When all this will be finished you can create the wings animation and repeat this animation in loop with the NLA editor, and move the whole armature along a straight line or along a curve with a Follow Path.
