Re: Deadly bacteria kills 9 in Florida coastal waters

I picked up a staph like infection a few years ago kiting through a cut from shaving that day. Not a pleasant experience. 2 weeks of feeling like walking death but it cleared up without hospitalization.

Re: Do Kites Fly Better with Strut Vavles Closed?

I also heard that if you apply a teflon coating to the bottom if your board, it will go faster.

Re: Do Kites Fly Better with Strut Vavles Closed?

I seriously doubt it. There is very little squeezing pressure on a strut bladder. There is bending for on bladders though. Is it any harder to bend a strut or LE with the valves closed by hand? No, didnt think so. Air compresses very easily, especially at the pressures our kites hold. A deformation ...

Re: RPM size to go with 12m Rally ?

Im a Slingshot dealer in Canada. My recomendations are: if you want to unhook or kiteloop heavily, go RPM 8m. The 8 RPM has a nice 4-5 knot overlap with the 12 Rally where the 9 has a little too much for my taste. It sits deeper in the window to improve freestyle ability but sacrificing upwind abili...

Re: Unexpected telltale results

El Rudo, "almost the same" planform can mean huge differences, especially with bridle changes. And i dont fault the industry for not licensing this concept. Truly revolutionary changes have been widely licensed across the board: LEI kites, single point inflation etc. so why not the venturi if its as...

Re: Unexpected telltale results

Another thing: slots on aircraft wings are always, or almost always incorporated into a feature that drastically changes the shape of the airfoil (slat & flap extension). They are not useful for standard AOA changes, but for maintaining lift through drastic changes to the camber and speed of the air...

Re: Unexpected telltale results

In theory the Venturi system should work. On aircraft wings slots are added to basically allow a secondary flow of laminar air over the wing to increase lift at low speeds. These are only used in specific flight profiles (usually landing) and only on specific airplanes (usually high speed/low lift w...

Re: Unexpected telltale results

Telltales near the trailing egde would be deceptive. A kite, similar to an airplane wing has a point where the smooth laminar flow of air seperates and becomes turbulent. The Separation Point always exists and as a stall condition nears, that point moves forward. Only when you teach the critical ang...
