I have : made two kites with valve-vents. First was a soft arch (15mx1.5m), this : had a strip of fabric the width of the gauze, which was sewn to the gauze : with a single seam that ran down the middle of both the strip and the gauze. : This kite failed to inflate until I removed the strip. Is there any milage in cross venting at the wing tips in combination with flapper valves on the leading edge gauze. THe idea being that you want to stop the tips deflating, (flapper valve) but you are still pressurising the tips from the main body of the kite. If the cross vents are big enough, then there should not be explosion problems. I feel this would work better than cross venting and sealing the tips (no le vent). Umm, did someone try making one with no LE vent at the tips? -- __ Andrew Hawken ________________________________________________________ a.hawken@qmw.ac.uk __ As far as I can make out, *I* am responsible?! __ andiih@micromuse.com ____________________________________________________
