Mostly cloudy today on the heath with the occasional spot of rain in a somewhat blustery SW breeze. Full vents with 4 wrap after initial attempts with lighter spars. It was sunny later in the afternoon after the end of the TDF.
Most of the personal kites we were using today have been in use for many years and are not in any way compromised by wear issues. The last set of 1.5 team sails arrived in 2008 at Portsmouth as I recall. We have just retired them from regular team use so they were good for seven years.
We have zig-zag stitched the leading edge mesh as necessary and have no reason to believe that this and frayed fabric edges have any real impact on flying characteristics.
The only issue that we have seen over the years with Revolution Kites is with ‘stretchy’ fabric. Some of the earlier sails we had made were only good for a short time and ended up on the walls of kite collectors. <grins>
