Hmmm, I have a Harrier 90 sitting in a box that I thought about returning for a Funtana 90. Are you saying that the Harrier 90 does not wing rock at harrier? I was skeptical at first because of the rounded wing tip and the constant chord. I even thought about cutting off the wing tip right from the get go.

But now that you point it out, it does have very low aspect ratio. Each wing half looks practically square. I mean the box that contains each wing half looks square to me. So does it absolutely does not wing rock? Or only at a certain setting?
