The Trango X-Race is a high C, the small size (this one) is actually a D, so definitely for advanced pilot looking for something to progress. It is more demanding (I think) than most (mid) C wings. 6.9 aspect ratio, which is about the same as most D wings, it gives a lot of feedback, great to get used to wider wing. It comes with the usual UP feeling, very precise and direct handling, super agile, great fun to fly.
I got it after 2 years and several hundred flying hours on the Summit XC4 (high B, AR 6.3), now stepping up to a 2 liner EN D. It worked perfectly for me, I did some of my best XC flights with it, learned a lot and now feel confident about moving up to the 2 liner.
It is an awesome glider, certainly my favourite so far, I wish I could keep it but can’t afford to have two XC gliders.
The 1st owner only flew XC from nice grassy launches I think, he kept the wing in absolutely mint conditions (except one tiny patch).
I’m the 2nd owner, I bought the wing 2 years ago (October 2019), done about 100 flights, 100 hrs. 90% long(ish) XC, a bunch of hike and fly, a bit of groundhandling and some SIV practise (because that’s important) and many wingovers (because that's fun).
A bunch of small patches that I fixed myself and a bigger one that was repaired professionally. 7 broken lines (ouch, take-offs here in central Oz desert are nasty!), all top cascades, fixed temporarily, but getting replacements lines from UP (won't be here for maybe 1.5-2 months tho, I'll forward them when they come).
The wing still flies perfectly fine, last flight I did was 115 km.
Porosity 6 months ago (December 2020) was around 250-300 sec (minimal value on the leading edge) (very similar values as in December 2019). I doubt it would have changed much since then.
Wing is in Alice Springs at the moment, can ship in Oz or NZ.
