A friend who owns a MachII has helped me understand that there is a wide range of setup for the wand/ flap relationship and so I was wrong in saying-absolutely- that when the wand kicks forward it causes a crash. As I understand it ,it is a matter of set-up and the wand could be set up to have that kind of authority but it is impossible to tell for sure by looking at it. However, that explains the wand springing forward with little or no response from the boat.
So I apologize for the incorrect information.
However, what is still clear is that a wand system still requires the ability to reduce or eliminate lift in order to control altitude. And on multihull foilers the flap movement will likely be much greater than on the Moth in order to facilitate large amounts of downforce from the windward foil.
