When fabric is worn out it is full of tiny holes. I've sometimes checked pieces of old kite fabrics under microscope and it looks bad. Damaged areas can have perhaps 5-20% of the surface missing from the air tightness perspective. It is almost same if kite has big holes in it.dave1986 wrote: ↑Wed Jan 08, 2020 2:38 pmThanks. I wasn't expecting that more porous fabric would effect the flight characterisitcs since I would think the air would enter the kite through the leading edge inlets faster than it can leak from the microscopic holes in the fabric?
I would imagine minimal UV degradation in cloudy conditions which we most get here in the UK. I suppose bridle stretch (which applies equally to any weight of kite fabric) would become a bigger issue if you mostly fly in cloudy conditions.
I find it interesting that Ozone charges disproportionately more for their Ultralight kites in the larger sizes.
