Reducing your VR/VQ/V wire wear

Postby nev » Fri Oct 25, 2013 1:09 pm

simply disconnect one wire where it attaches to the A-frame (when not flying of course)

e.g. Typical day out, say 6 hours, with 90 minutes flying.
    Wires disconnected - 90 minutes wear
    Wires connected - 360 minutes wear (while the wing gently rocks) - thats 300% more wear!

Apologies if this is egg-sucking, but I was asked the other day why a wire wasn't connected.

Sometimes you have watch pilots like nev & ask certain questions in relation to rigging the Atos . I have found it makes life easier.
This makes sense & I have altered my practise.
safe flying

Nick, have you tried picking up an VR/VQ/V without the witres connected?

I challenge you to do so and try moving your glider, say, 2 metres ;)

Wing flops all over the place, and makes you think 'WTF is wrong' while you are stationery with a wing stuck in the ground..........

I've got into the habit of hooking my harness over a wingtip when parked, to stop the rocking, but just thinking about it I guess pinning the wing down like that when it wants to move in the wind maybe puts more strain on the sail, etc ?? Any thoughts?

I've been known to attempt a take-off without clipping in so the idea of disconnecting a sidewire between flights would worry me. But I'll have a go at moving the glider with a wire disconnected, as you suggest Nev, next time I'm out, just to convince myself I couldn't do something very stupid.

I'm sure the harness on the tip will be fine Chris.

For stress on the sail just park/load it against the wind - so much force that it would aid in the delamination of pre-2004 AIR base bars! (they are beefed up now BTW)

Ive just changed the 3 wires that make up the A-frame / closed-loop system.

I'm pretty sure that disconnecting one A-frame wire when not flying has reduced wear - in the past I usuallyu get the first sign of a broken strand after the first year (circa 100** flying hrs), but my most recent set have lasted three years (circa 300 flying hours)

** - clearly the 100 flying hours could be, say, 200~300 'wear' hours if I only fly for (say) 30% of the time rigged at the hill.

One question - does anyone 'treat' their wires? My original VR wires (from AIR) seemed very resilient, but subsequent (UK) replacements have all showed signs of weather degradation pretty quickly. I read a post on the RW/Yahoo groups recently about an old sailplane practice involving an annual 'wiping' of all wires with a rag soaked in something.........and ideas? (obviously the downside is it may find its way onto the sail!)
