Thinking of bumping up from 130lb to 150lb
Would this make good material?

At altitude the 4 watts should be more then enough. Using it like a HAM on the ground will show some weakness at 4 watts but not a lot...

Thank you for sharing this inspiring flight. Scenery, esp in the beginning, in beginning was just fantastic. You were really rewarded for your efforts. Wishing you more of the same.

I'm flying a first production year U2-160. I would love to have a T2 but I've been having great luck w/ the U2. I'm now thinking I'll see if I can get a new current U2 sail for mine. I'm itching to find out how much different it may be w/ a new sail and the newer sail cut. I figure if I upgrade my U2 and like it even more I'll stick w/ it. If I still yearn for a better glide I'll get a new T2 - keeping the U2 until I feel at home in the T2. If I should then get rid of the U2 I'll likely replace it w/ a Falcon 4 (for those after work or short time period windows of ridge soaring opportunities).

Now, if WW were to come out with a U3 ...... I know what I'd be getting ASAP.

An old test was to find an area that has only a single thickness (not reinforced like near entry holes or grommets), put a dime perpendicular to it and shove. If it leaves a significant dent, it's time to have it looked at by a professional. If it goes through, it's time for a new sail.

Yes, the latter has wrecked the sail, but it was done anyway!

take how much the color has faded with a grain of salt
different colors fade different amounts

You need to worry about how much the structural integrity has deteriorated and that does not necessarily correlate to how much a particular color has faded

Not saying this is the case but you can have the color fade noticeably and the sail is just fine
you can also have a sail of a different color that has faded much less but the material has degraded more

Use some sort of force method to determine integrity of the material not an unreliable visual method

Your description of the sun-fading sounds really serious. The leading edge (color) pocket is not structural to the sail, but it is a good indicator of the sun-hours. I would say, the sail is toast, and I think WW would agree. See if you can find a younger sail (I hate to trash an airframe), or maybe a younger glider (which may cost the same or less) during the off-season. Selling prices go down, when the snow flies.

For the future, most glider bags are really not much protection from the Sun. From my web page: "A glider cover-bag of blue Yachtcrylic (or Glen Raven's Sunbrella) is about bulletproof to sunlight, and its' sail-killing UltraViolet radiation. Sailing yachts in harbor use blue Yachtcrylic (or Sunbrella) for their sail bags, and yacht sails make our gliders look inexpensive. One such cover-bag can probably outlast your next several gliders. I do not hesitate to spend the price of a UV-proof bag for my wings; I live at 5k' MSL, fly at 10k' MSL, and sunlight here is really intense." More here:

UV exposure can be a bit tricky to calculate as it is more to do with how long the glider has been out in the sun rather than just the flying hours time. Also the amount UV exposure can be very different from from area to area. Read somewhere that 1000 hours for Dacron sail cloth and less for Mylar film type sail cloth is a guide.

Wills Wings have a good page on sail options and some are UV resistant http://www.willswing.com/features/sailcloth.asp
I believe most sail makers have testing equipment to judge the condition of UV exposed sail cloth.

Interesting price and radio; I see from the specs that its a 4watt though...
Im no radio expert but for me anything below 5watt was a no go.

Any comments for the 4 vs 5watt?

Edit: I use a quansheng tg-uv2...bang for the buck me thinks...

Is this an indication that the glider is too UV'd out or does it still have another full season left on it?

Just wondering if anyone had any knowledge about UV limits on a glider. I am eternally trying to keep it out of the sun but flying is flying.

The rest of the glider is in good shape.

S2 to topless is a big jump...
can be completely manageable and appropriate but not for every pilot
The trick is you will never know for sure until you take a path

your potential paths
S2 to T2....take it easy, big LZ's at first...in a few months your are loving it
S2 to T2.... it ends up being way too much, you go back to S2 or U2 if you are lucky enough not to have hurt or really scared yourself
S2 to U2 to T2....once you get to T2 by this path you realize even from U2 to T2 is significant step

If you are the kind of guy that excels quickly at everything you do and are going to fly much more than 50 hours a year you may be fine and love the topless

if not, going to a U2 is most likely the best step

but...what many people that move back from topless to king post don't admit is that having flown a topless made them a better pilot

a U2 can better prepare you for the jump than a S2 but ultimately the only way to be able to fly a topless well is to fly one

The U2 is closer to S2 in ease to fly, but closer to the T2 is performance

I can hardly wait for the weekend to try this out! /jd


I vote for the Foxtrot. Better timing for light air.

I transitioned from a U2 to a T2, I think the difference is probably more than 20% at 40mph. Handling is another question. That*s become better lately.

If your taking lessons your instructor should be providing all of this information. It's up to you how much you want to spend as there are varying levels of
all of the support hardware Vario, GPS,parachute,helmet, harness, radios etc.. Usually we start out on entry level of everything which is much more cost effective and once we become proficient we trade up. Things like GPS and radios are things that usually come later. Harness,Vario,good chute and helmet are all thats
needed to begin.

Hey Scott, I think your experience is pretty representative. Every other pilot I've spoken with opted to get the glider flying right and landed without a problem. Two other guys who I spoke with at Funston had it happen in much closer proximity to the ground than I did and still managed to recover the glider before landing, one with more effort than the other.

Although it's my aim to never abuse my wing again, if I do and I lose a few tip ribs, I think I will recognize it right away and will try to get flying again rather than grabbing for the red handle.
You were pilot in command and got down safely (Kudos). Only you can look back
and know if deployment was really necessary. You made it down safely thats what counts. Great deployment reaction.

One thing you could have done to give yourself enough time to evaluate whether the wing was still flyable would have been to do this kind of stuff with a bunch more air between you and the planet. Tossing the laundry without hesitation and then reaching the ground immediately after a quick opening kind of implies that you didn't have much margin for error. It would be one thing if you had a zillion of these wangs under your belt and were completely comfortable with them, but your narrative suggests that you're still working things out. Give yourself a couple of thousand feet of buffer instead of relying on everything else going perfectly.

> Altimeter, Barometer, Air/Groundspeed Monitor, Compass, GPS

This is usually the same device, a vario[meter] with optional gps and airspeed sensors.

Having just started, you're probably better off getting a used simple vario – it will show you 1) your altitude and 2) your rate of climb/descent (with sound), which is the most important part for thermalling.

You might want to get a vario with built-in GPS to analyze your flight path post-flight, or view ground speed etc. in-flight. You don't need an airspeed sensor now.

Depending on where and how you will be flying, you might need a radio and a tree/survival kit. You will be better off talking to local pilots about this.
