Ok so I have an older model Supersonic, put it together for the first time.

 

The Instructions say "The lead. edge curves back rounded, not flat"

 

Viewed upside down from the back, Is this what that means:

It is very interesting, anyone know what the curve is supposed to achieve?

 

I am really interested in seeing how the wind pressure affects the Curve too.

That looks similar to my Blast and Power Blast, which are supposed to have the same curve.

 

Simple answer, the airflow becomes like that of a wing ... so the faster you go forward, the more lift you get ... which in this case equals power.

 

I can hold my Power Blast 2-4 in my finger tips at the very end with the leading edge facing into the wind and essentially fly it to keep it level. Try that indoors and unless you're Chuck Norris you won't have the strenght to lift it with your fingertips. ;)

Might have something to do when the sail becomes loaded and is forced to the back.

A curve is built into the airflow's shape, just like a plane's wing.  Proof lies in the fact the you can "dead-launch" the speed series kites

Thanks for the responses guys.

 

It is a very interesting kite, Just need a decent wind now.

you can frame it lighter, but you'll loose that discussed curvature if you go to thinner diameter leader edge tubes.

 

It will fly in lower winds with lighter weight down tubes only, just be careful with how much wind you "test" it in,... 

 

my supersonic has 2P SS down-tubes for our local conditions, but the "real" spars are in that case if it EVER started blowing hard enough to warrant the increased weight & strength.

The curved leading also eliminates the need for leading edge venting as found on the standard Revs. The air flows easily past the leading edge in reverse flight instead of "welling up" against it, making reverse flight faster and easier than a standard Rev.

Wow, and I didn't even know what the mesh was for on the others.

Thanks.
