You can get it for the asking. Second, here is the address and phone: Health Sports Technologhy Group 216 Loma Vista Street Suite G El Segundo, CA 90245 phone/fax: 1-310-414-0977 Third, if you contact them, tell them that I sent you. Fourth, HSTG sponsors Storm Front and I sell their products. Fifth, the data is in a graph, which I've interpreted to get the numbers that I am placing in the following table. The weights are for 32.5 inch spars. Sixth, my memory is not so good, but was not wildly incorrect. Here's the data, I've sorted it by weight (in grams). The deflection is in inches with a non-specified weight hanging in the middle of the spar. Spar Weight Deflection ---------------------------------- SkyShark IIIp 11 .42 SkyShark Vp 13 .37 Rev 2 13.4 .45 SkyShark VIIp 16 .31 Rev 3 18 .33 Rev 4 27 .22 I use the Vp spars in the light wind team kites. Individual flyers can probably use the IIIp spars, but team flying usually abuses kites more than individual flying. Regular to high wind kites use the VIIp kites. For really high wind, I switch to more highly vented sails (more screen door material) and stick with the VIIp rods. One interesting thing about the trend towards light weight spars is that, generally, it is easier to helicopter slide and to land a heavier kite than a lighter one, given that the kite isn't too heavy. That's why I've gone to adding weight to a kite as the wind increases... -- Marty Sasaki Harvard University Sasaki Kite Fabrications sasaki@noc.harvard.edu Network Services Division 26 Green Street 617-496-4320 10 Ware Street Jamaica Plain, MA 02130 Cambridge, MA 02138-4002 phone/fax: 617-522-8546 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
