Hey everyone, I'm a young pilot aspiring regular 300-400km flights. Currently I have done a few XC flights in an SZD 51-1 Junior at 100-200km already but I'm limited by club members who want to fly as well.

I've been looking at a few gliders and read a lot of reviews but still would like some more information besides club members and a few websites.

Currently I have an eye out for these few (in order of current interest):
DG-100/101, LS-1f, Standard Cirrus, Libelle, ASW19

I'm a fairly slim and small pilot at 1m 70 tall and weight without parachute at 60kg. I have 70 solo hours, most of them in SZD 51-1 Junior and about 15 of those with both LS4 and Centrair Pegase.

My ambitions are 300-400km+ flights, some local competitions for fun but nothing too serious. Easy rigging is a plus. Budget would be between 10-20k euro's.

What would you recommend me?


Get a Libelle and thank me later. Just don't get tall like me.

After having spoken to a few DG/Libelle/Cirrus owners I am really considering the Libelle. What would be the points to look out for when buying one, in your opinion?

I do not have so much experience with the Libelles, but things I remember:
- As with all Glasflügels: Check if the connection between the main pins and the wing spar stubs is okay (http://streifly.de/TM201-31.pdf). Repair needs a professional workshop
- check the ailerons for excessive play. That's a quite common issue with the Libelles. In many cases, a fix requires sending the aileron drives to Streifeneder
- check for play in the lift pins. This cannot be removed with washers as with the F, but the pins will have to be replaced
- check the air brake drive for free movement
- check the elevator drive for play and any hidden cracks
- check if all the AD have been taken care of

Best,
Christoph

In the Wikipedia article:

https://en.wikipedia.org/wiki/Glasflügel_H-201

it says:"they are quite sensitive to sideslipping and have relatively ineffective air brakes that make short landings tricky for inexperienced pilots".. I wonder what 'sensitive to sideslipping' means in this case.

From what I've heard is that performance decreases very fast when you slip it. So you must fly it pretty accurate with the string in the middle.

True enough, but the same applies to all gliders. You'll soon learn to
fly a Libelle with the string straight because it that: its no harder to
fly straight than any other glider, and it does like the string to be
pointing out slightly in a thermal turn.

Due to the shape, the fuselage should be well aligned with the flow to prevent seperations. But from my experience with this glider, it is not really a big issue. What I found more noteable was the inefficency of the rudder and the ailerons, in particular at low airspeeds. When entering a strong thermal, you sometimes need to speed up to get her into the turn. That is clearly not necessary with the LS1-f. But many people like Libelles, too. It certainly looks nice. So to each his own.

The airbrakes of a Std. Libelle are indeed not very effective. But this is something you get used to. It is the same with ASW19 and Std. Cirrus, unless they were modified with a second panel. There are approved modifications for these two models, but not for the Libelle. Some early Std. Libelles had top- and bottom airbrakes which should work better. All LS1 have quite powerful airbrakes, they work even better compared to the double-panel brakes of an ASW19.

Mine is one of these. I've also flown a B series in the distant past and
don't think there's much handling difference between mine with top and
bottom surface brakes and the B-series with single surface ones.

Note that most Std. Libelles are B-series, with foam in the wing skins,
water bags, top-surface brakes and a revised tailplane. The first B-
series was probably s/n 182, but the change-over was gradual, starting
from s/n 85.

Pass. Mine has no bad habits when slipping and tends to come out of the
slip at the same speed as it went in, assuming that was the trimmed
speed. It does comes down fast in a full-blooded slip thanks all the drag
generated by pushing that razorback tail boom sideways. This compensates
nicely for the relatively weak airbrakes - but even Libelle brakes scrub
off height quite nicely if you push the nose down.

About the only thing a pilot needs to watch is that a fully held-off, two
point landing is a little trickier than in, say a Pegase, Discus or
Junior because the brakes aren't doing a whole lot after you've flaired.
So, if you're a little quick to lift the nose to the two point attitude
the glider will balloon. A lot of pilots put Libelles down on their main
wheel for this reason, but unless you're asleep behind the stick its easy
enough to correct for the balloon without making a hard landing.

That said, I usually do two pointers with mine because I like the feeling
of both wheels touching the ground simultaneously and staying down. But
it did need a bit of practise at first.

There are a few Std. Libelles that were modified with split flaps: http://libelle.bugwiper.com/tuning.htm (towards the bottom of the page). But this is not available anymore. Libelle with these flaps may not be modified with winglets.
