Hello Maugan,
Of course I have. I referred to the two control schemes in production without saying their names, Hobie Cat and Rave. I just wanted to be sure I didn't step on anybody's toes so I didn't use any company names.
By the way, the wands do not control pitch angle; they control lift by varying a trailing edge flap. The scheme with the water ski out front controls lift by varying foil angle of attack.
