Just found this info on the new Slingshot SlingWing
Looks like Slingshot were the first developers of the single-strut inflatable wing and have been refining it since 2011 - waiting for big lift foil wings like the Infinity 84 and 76
Construction quality looks first rate in the pix and I like the window.
I've got my order in with Jesper - arriving late June, can't wait. Kook times ahead
