UFO 14, produced in 2016, just flown for downglides and rarely used.
It has a scratch on the outside of the wing (see foto) which was professionally repaired by paraclinic.at
They also measured the porosity of the wing (foto) with the JDC method (http://www.paraclinic.at/nachpruefungen/) and said the wing is in a very good condition:
Value: 862 s (>350 s means neuwertig as you can see on the website, a brand new wing has ~ 1000 s)
I sell it because i change to another type of wing and don't need it anymore.
