It's not a rev. At least using the definition of a product of Revolution Enterprises.
Anybody who's spent any decent amount of time doing 3-d bridleless flying knows that a Rev will work "inside out." But they also know the kite flies better the other way around.
This so called StringRev flies best/only with the spars on the bridle-side of the sail.
We use them for high winds (+ 20 Mph)
Al the credits go to Ruud de Haas who made these.....They fly even better in reverse than normal forward flights !!!
