500 Meters in 30 Seconds - WINCH LAUNCH
Вставка
- Опубліковано 14 бер 2022
- A winch launch is the fastest and cheapest method to launch a glider. It was great fun to fly the LS3 again. The noise of the glider is horrible at the moment, I need to seal the canopy properly.
Thanks to my former club MBB SG Augsburg: mbb-sg.de/flugsport/

The unbeatable feeling of an good but not too strong winch launch is just priceless.
My first glider flight was a cable launch in a Slingsby Sedbergh, I just about crapped my self as we pitched up against a stiff breeze, but after a few seconds it wasn't so bad.
Oh how I miss doing this - I've not had this experience since the mid '80s, winch-launching in an ASK-21 at what was West Malling airfield in Kent (now a damn housing estate), then catching thermals over carparks and business parks in Maidstone, spiralling up and gaining altitude to be able to head up Blue Bell Hill and on to Rochester airport where you could get massive thermals from GEC-Avionics' huge car park (who would have guessed then that I'd end up working there a few years later) and then head off all over Kent for a few hours of sublime peace and quiet.
An ASK-21 in the mid 80s... our club still mainly flies the K13! And only in the spring and autumn does the Grob Acro come out.
@@yellow326 Re: K13 - Now that's proper "retro", and a classic at that, I wouldn't mind giving one a go 😉
Very nice. Just a little early spring thermal flight with winch a launch. One can see that you are very focused on the winch launch and you still have fun with those little flights.
Habe das einmal selbst als Passagier mitgemacht. Cooles Gefühl und cooles Video! Muss man mal selbst erlebt haben 😀
Ah, envy you this. Miss that so much. Unfortunaly i lost my medical last year. Hopefully i can get back in the air in 2023.
your landings are so smooth man
Well done, sir.
Awesome video 😀😀😀
Cool how this guy plays a flute while he flies his glider. But he's better at flying than playing a flute, I'd say.
Sometimes you just want to fly like a jet :D
Always feels funny in my ears 👂 🤣
Hi Stefan, thé first Time I Saw a winch launch was horrific. I really thought the wings will brake at One Time!!! The stress seems to be enormous isn't it?
You should visit Wittstock/Berlinchen.
They can pull you even higher in good winds.
My record is 720 meters.
That is so cool!
So I fly F3J RC competitions. I was hoping for bucket and zoom at the top!
how long is the runway and the wire needed for this type of launch?
Finally a IRL video 😆👍
Nice one
+Хороший полёт. Успехов вам желаю
Do you get a lot of g's during a winch launch? I wanna try but also I already feel like passing out when doing rollercoasters xd wondering how much acceleration you can feel in this case
No. Only a very brisk acceleration. When established in the full climb, it’s a rocket ride! Nothing like a roller coaster unless the cable/rope/wire breaks.
Stefan - how long of a cable/runway is at that field in order to achieve the gain you got? I've been looking at a winch for our club. Is there a ballpark ratio of length of runway and cable vs what altitude can be achieved?
I think it is around 1m of height for 3m of cable. We have a 1200m cable winch at our club, and average a 400m launch height
@@deflyingfarmer Seems realistic. We get 300-350m on 950m rope. Depending on what plane, pilot, winch driver, weather, the usual.
Depending on the whole System you might get higher release heights with plastic rope over steel cables.
Thank you, everyone, for the replies! So a 3:1 roughly seems like the better end of yield for the winch launches. I've run this idea by our club for when the tow plane is busted, etc. And it would be great for training at our club.
Strongly depends on the headwind. We usually get 400 metres on an 1100 m cable (dyneema), but it can be anywhere between 300 and 550 between slight tailwind and good headwind. In fact, if the winch is rigged to allow extension, light wooden gliders can kite all the way up to the end of the cable if the wind at altitude is strong enough.
@@steilkurbler4973 ... jetzt musste ich gleich nachsehen ob es beim Steilkurbler auch so legendäre Videos wie beim Flachkurbler gibt, leider (noch) nicht. Schönen Saisonstart wünsche ich.
@1:41 to 1:44 : On the left and upper part of the frame : is that a bird or a plane ? Seems to be approaching fast !!
RIP an die Sollbruchstelle
Epic, handled the Gs well!
There are no G-forces when winch launching
buuuu das var coooool ! wan haben sie ein plan ins Montenegro comen? gruse aus MNE :)
I'm wondering... did he "choose" to park exactly where he did or is a bit of "luck" involved?
PR: 720 meters on 1200 meters of wire back in 88´ish on a Ka-8 @ 40 knots wind :-D She went straight back in to the hangar after that start pr. instructors order :-D
It would be so helpful if you can see thermals on the map
500 M, what do you mean 1,500 ft? Well we used to do 850, so where'd you get 1500 from?
Do you have any good ideas how to seal the canopy frame of LS gliders? The whistling noise is annoying...
Servus Stefan, ich weiß nicht wie man das auf Englisch nennt, aber wir benutzen am Flugplatz Ruderspaltprofilband, muss man beim schließen der Haube aber aufpassen. Es gibt aber auch ein V-Band dafür, hier ein Link. 😉

It's possible to use rubber tubing, Iv'e even seen it done with long strips of yarn although for almost all methods it's tedious and takes large amounts of time. Good Luck! :D
Wir haben den Winter mit diesem shop.streckenflug.at/bs_product_info.php?products_id=2345 Band eine unserer 300er Hauben abgedichtet. Ich habe die V-Band Methode auch ausprobiert, mit der Anleitung von Thomas Raaf: facebook.com/groups/542889379807954/permalink/546244362805789.
Wo bist du da geflogen?
Schöner Flug
In Augsburg :)
Ich fliege in eddh, in der Nähe von Hamburg, musste auch mal hin, da kannst die Ostsee und Nordsee gleichzeitig von oben sehen.
So is 500m in 30 secs unusual for such a launch? And how about the reverse: could you drop 500m in less than 30 secs?
Yes, that would be possible for most gliders.
As JJ said at the convention: why is no one concerned that the glider is overstressed by this?
Sounds like a F16 xD
Hallo Stefan
Das war zwar nur ein Spassflug und kein Wettbewerb, und wahrscheinlich weisst du es schon, aber der Klappeneinsatz bei 2:20 war nicht ganz optimal. John Delafield schrieb in seinem Buch „Wettkampf Segelflug“, dass viele Piloten die Klappen ineffizient anwenden. Was er sagt klingt logisch: Beim Hochziehen bleiben die Klappen negativ, wie du es ja auch gemacht hast, Es sei Unsinn, mit mehr als 1.3G zu ziehen, und das Bisschen Mehrauftrieb kann das Profil auch negativ vorwölbt hergeben. So weit also alles bestens. Dann aber schreibt er, in der Parabel beim Nachdrücken werde trotz abnehmender Geschwindigkeit sehr wenig Auftrieb benötigt. Die Klappen können also negativ bleiben, was einiges an Widerstand einspare. Sie sollten erst NACH der Parabel in Thermikstellung gesetzt werden, wenn wirklich der volle Auftrieb benötigt wird.
Beim Abflug aus der Thermik setzen offenbar viele Piloten die Klappen zu spät negativ, und das habe ich hier auch bei dir beobachtet. Auch beim Nachdrücken in den Schnellflug reduziert sich der benötigte Auftrieb wegen der Parabel, die das Flugzeug beschreibt. Du kannst also problemlos direkt aus dem Kreis heraus die Klappen hoch stellen ohne vorher die Geschwindigkeit zu erhöhen. Das Flugzeug sollte von alleine die Nase senken und in den Schnellflug übergehen.
Ist wohl alles „kalter Kaffee“ für dich. Wenn nicht, könnte es dir wertvolle Sekunden einsparen beim Wettbewerb.
In diesem Fall war es nur rein zur Gaudi und ich hatte mir keine Gedanken über die korrekte Klappenstellung gemacht. Trotzdem ist das immer wieder gut zu hören und auch bei Thermikflügen mache ich das nicht immer optimal. ;)
Winch launch, the best way to launch.....Actually it's more about what my bank balance can handle 😀
Wait, a winch launch is 6 or 8 € on your bank account, while a tow is 40 € at least.What are your measures? My numbers are for Germany.
@@chrisehmke1651 Not too different here in the UK where I fly. Winch costs a little more, tow costs depends on release height. I predominantly winch launch as it's the cheaper method.
That girl in the back, playing that flute is awful ! 😄
Bungy launch, gravity launch and auto launch, probably cheaper............
@@randomguyinanglider The world consists of more than flying Arci out of grass airfields...... and most of the early pioneers managed to do long cross country flights from a 10m bungy launch.... you can gravity launch from a surprising number of ridge sites in the right conditions.... just pointing out there are other maybe cheaper alternatives...
@@randomguyinanglider You do know that more people are killed per launch, using a winch, than any other launch method? - I'd call that a drawback...................
@@randomguyinanglider So that's the whole gliding community is it? What an idiotic and facile argument -do you posses any intelligence?
zero G ? ;-)
I believe the top right-hand side gauge is showing how many Gs you're pulling like a fucking fighter pilot.
it is a variometer that shows climb/sink rate, even though some gliders for acrobatics have a g measuring thing
Stop wars
WTF is a winch launch.
Please explain.
did you get the answer ?
@@heisenberg19989 No
@@andybaldman its a giant rope thats connected to the glider. as the rope is pulled in by the winch it pulls the glider along very quickly, allowing it to gain enough speed to lift into the air. then the rope detaiches from the winch and u can fly away
