Weight?? Maybe the battens add an ounce or 2. Lets be honest now.
Firstup - full credit for running an excellent kite design website. I like how kite-stuff focusses on kite design without hype from people pushing product. I think some of the ideas there are leading edge.
I wasn't really clear in my first post. I'm most skeptical about battens on the leading edge. Manufacturers claim improved "stability" but it seems too many other variables are changed from year to year to really assess this claim.
As for reducing flutter on the TE, this can be achieved through the scalloping the TE and while this sacrifices a small amount of area it does so without adding weight. I'm still not convinced that the added area maintained through the use of battens sufficiently offets the penalty from the added weight. Have you tried scalloping on your designs?
In addition, battens add to the manufacturing time & complexity as well as making kites a little harder to pack and store. I hope designers can come up with designs that don't need them to fly well. There are already examples out there...
