Congrats! Looking forward to seeing some photos.

Not only pigeons come home...
I had no idea.
My Libelle actually started life at my very own gliding club, back in the early '70s.
Its original owner was a member back then. It obviously went through a number of owners and clubs all over Australia during the last 43 years.
Its then owner even loaned her to a Spanish pilot to fly in the Waikerie World Championships back then.
The pic shows her at Balaklava GC when she was new, in early '70s.
The Blanik AP in the picture was the glider I soloed in, 1979. This image holds special meaning for me. I left the club in late 1980, and rejoined August 2015. Looks like we both have come home.
What goes around, comes around.

A fantastic result, Frank!
Great photo, quite appropriate. Don't sleep with the Libelle every night, make time to watch "Zulu Romeo" again to look for CT.
Oops, sorry I didn't remember the right Gilbert.

Nick, the belly release works, as it is used as part of the trailer restraint system.
She is fitted for water, but the bags are removed. The last owner made some new ones, but didn't fit them, as he wasn't happy with the result. I have them now, but will not be installing. I don't like the idea of winch launch failure, and a hurried landing with full wings. It comes with an old radio that is functional, Flarm, and some sort of GPS nav system I haven't even looked at yet. The instruments are old but adequate for now. My club has 4 parachutes which rarely see the light of day, as almost nobody flys the singles. I will use one of those for a while.
I will definitely have another look at ZR again and see if I can spot her!

Sounds good.

As far as the water is concerned, Libelles only hold 50 litres anyway so it wouldn't be too much of an issue in the event of a launch failure. In my memory water in the Libelle didn't really make an enormous difference with performance, but it did make it feel a little less like a cork in the ocean in turbulent conditions.

As far as the Balaklava parachutes are concerned, I had custody of one of them over the summer, as Eric borrowed mine for the Junior Worlds.

I fitted some larger water ballast bags in a 201B. It does go better, but somehow feels less lovely than a Libelle normally does... Felt more like other gliders!

Another go-faster trick you might consider is fitting turbulators. This
used to add a point to the UK handicap (89 - 90) though the latest
handicap list seems to have dropped the '+turbulator' handicap. Anyway,
its a full span zigzag mylar turbulator on the under surface just ahead
of the undercambered region. Has no effect at lower speeds, but stops
flow separation in the undercambered area at high speed - at least that's
what I was told. It was on my Libelle when I bought her and certainly
high speed cruise around 70-80 kts shows less height loss than I expected.

If you're interested, talk to Glasfaser, who can supply the tape and/or
fitting instructions.

Hi Martin,
That sounds almost too good to be true. Quite a simple mod for tangible gains.
I assembled the bird today and had a good look at her. Everyone was pleased with the choice. I'm a little short of achieving the skill level to fly her just yet, but will work on that. I'm still bashing around in the single Astir. Landings need attention. I have only been back flying since late August, and solo again since mid November. No need to rush.

Yes, you'll find that landings do require attention because its
relatively weak brakes mean that a Libelle will float further and have
more of a tendency to balloon than most other gliders. For this reason
you'll see a lot of not fully held-off landings done with them: going for
a two point fully held-off landing is almost guaranteed to balloon until
you're fully up to speed with it.

Your early efforts to avoid ballooning a landing will probably result in
a main wheel landing with a tiny bounce. This is normal. FWIW there is
one other Libelle on my field. Its pilot almost always lands this
way, is an instructor, and has at least 5 years more years on type than I
have. I've worked on two-pointing mine 'just because I could' and can now
do that most times, but I've had mine for 10 years and have only managed
mostly two-pointing it for the last 4 years or so.

BTW, its useful get up to speed with slipped approaches. Libelles slip
beautifully with full brakes out and this gives a nice steep and
controllable approach when you need it.

Looks good Frank. The undercarriage looks different to usual.

Out of curiosity, what instrumentation came with it? Is the water ballast serviceable?

You got the right Gilbert Jim

Nick.
