Should I pack my glider loosely or tightly?

Where on the wing does porosity matter most?


We all know that the less porous our canopy fabric is, the better. It is important that our wing stays pressurised, and cloth that leaks air will reduce that pressure. But is it equally important all over the wing, on the bottom and on the top surface? The proper maintenance [...]

Canopy porosity In the past two articles we’ve focussed on line length and strength. But our gliders’ performance and safety also depends critically on the porosity of the fabric because increased porosity will reduce internal pressure. So how good does the porosity have to be, and what causes it to [...]
