If what you are saying is true, then why does the Harrier 3D not rock the wings in a harrier? It has huge barn door ailerons and tapered wing tips. The only difference I can see is the aspect ratio is way low. Yes, the airfoil is different too from the Funtana, but this plane has been optimized for harriers, so why then does it have tapered wing tips? I flew a Harrier once, and didn't really like it, so I got the Funtana 90. Now that I have flown the Funtana, I wish I bought the Harrier. Maybe I'll get one next, but I need to destroy the Funtana first.
