RE: CrazyBall
I made one tiny change to my Crazy Ball. I added two 1.5 mm carbon rods running thru the fuselage, each tieing two servo cases together. That stiffens them up some and should give me a little more control surface travel. It may also create a new break point. We'll see.
I think my Crazy Ball is now in a fairly stable, just go fly it and have fun! state.
