Why not keep the wing foil clean and wipe down with a silicone to prevent bugs from sticking. Also. Bugs will be close to the ground. Would not think there would be as many up higher causing drag or changes to the air foil so much.
Because no bug coating is perfect (and silicone needs to be re-applied, has environmental impacts, is more labor intensive). And yeah, bugs are mostly close to the ground, which is exactly where you take off from. So you need to wipe off the bug juice after passing through lower altitudes.
@@TheAnachronist Bugs are not only close to the ground. They are caught up by thermals and will rise to the top of the thermals. I have seen groups of swallows at 6 thousand feet having a feast eating bugs. Swallows can help a pilot find a thermal.
It’s enough drag that the old glider computers used to have a bug setting. You could tell the computer how much bug contamination you felt the wing had and the computer would downgrade your glide performance. This was before bug wipers.
I'm no expert but would assume very little impact. I think the LS3 has water ballast anyway but not sure if Stefan flies with it. Also I see this on the Wikipedia page.. "In spite of its weight the LS3 is a nimble climber. It is also less sensitive to rain or dirt than other types with the same [wing] profile." So I'm not convinced that the extra drag of the kit out ways the benefit. But like I say, I'm no expert, so what do I know. :)

Hi Andres, the bugwiper wings are equipped with nylon filaments, that scrape the bugs off the wingnose. the bugwipers are not mounted on the wing, they just stay in place because auf the aerodynamic forces. The retrieval line, that is powered by the electric winch, guides the bugwiper on it´s way to the wingtip and brings it back to the parking position at the fuselage. So you can clean your wings regularly during flight and and maintain full glide ratio.
@@wolfgangzimmermann6468 Thank you... I have been dreaming with gliders all my life and still I had no idea something like this wiper even existed ! Go vegan and fly safe !
I said that the wrong way round in the video. Of course you can only bring back performance, the glider already has. But a loss of 15% when flying a dirty wing at higher speeds is realistic.
Tell me how much disruption of air flow there is when these are installed compared to a clean wing. I bet it's at least 10-15%. If you don't test the difference in a wind tunnel ... then it's a wank.
and there is NO WAY I would drill into that fuselage. Just another excuse to void a warranty when micro cracks develop. There are treatments such as the latest developments in graphene with a hardness of 10H that last for 3-4 years and the crystal protective coating won't wear away from rain or the sun.
@@stanislouse4168 I don't know of a single insurance claim void or a warranty void as a consequence of the installation. Micro cracks on a fibre glass fuselage, from a tiny drilled hole? Never heard of that. For all the holes drilled into fibre glass ships for a mirrored of reasons - there has never been any negative outcomes that have ever been reported.
Mir hat das original Design der LS3 besser gefallen, ich finde die "Oldis" sollte man nicht optisch aufmotzen. Red Bull hat ihrer T28 Trojan zB auch ein neues Design verpasst und ich finde da ging der Schuß gründlich nach hinten los.
Einer von uns hat schon ewig Kennzeichen usw in Dunkelgrün, dazu orangene Warnfarbensticker. Ich bin sicher wir sehen davon was in stefans WMVideos, aber die SN ist einfach stimmig und schön in meinen Augen… also das Grün passt überraschen gut zu neonorange 😂
Very interesting, would like to see how they work in flight. Stefan, Your LS3 looks great with the silver nose with the SteFly- Eagles on it. *Just Striking!* 👍
Грубая ошибка 1! (8:05) Это плохие разъёмы я от них избавляюсь даже на радиоуправляемых игрушках! Гораздо лучше работают разъёмы с трубчатыми контактами. Грубая ошибка 2! (8:05) Эти разъёмы категорически нельзя паять вставив ответную часть разъёма! Пружина разъёма утопит в пластик прогретый паяльником контакт. И будет потеря качества контакта. Это проверено многократно!
Why are the motors so large? There is not a lot of space behind the cockpit to begin with. The new bug-wiper company owner needs to make the motors 5x smaller in size with same performance!
Those motors are Aircraft Certified. My brother says those motors are used as trim motors in many airplanes. It could be that they are used because they are FAA certified and very common in aviation and therefore easy to get at almost any aircraft parts supplier. This could be why..
Awesome!!! I wonder why some people are saying this is a waste of money. They are wrong, bug wipers gives negligible air resistance than a wing full of bugs. Please upload a video of using the bug wipers mid flight. I would love to see that 👍👍👍✨🎇🛩🛩🛩...... by the way your glider is so beautiful with the cool eagle.
This wiper isn't cut to the profile of the wing! That will produce burbles and DRAG. Just look how much effort a manufacturer takes to get smooth laminar flow, and you're going to goober THAT up with this system???
mücken putzer sind echt ne tolle sache leider kann man sie nicht in den bug einziehen. um ihren eigenen wiederstand zu veringern. btw die ls3 glenzt jetzt wieder richtig toll. LG aus Bayern :D
Bei den neueren wie z.b. ASG 32 ist das am Übergang sogar so ausgefräst, dass die Mückenputzer versenkt werden. Nur wenn man nachrüstet geht das eher schlecht…

DRILLING HOLE IN MY EX! How dare you!!! ;-))) Wish you great flights and no bugwiper lost or missing in action :-)
I dont understand this... bugs fly low, very rarely above tree canopies. Only spider webs can be found in the top of thermals. Maybe , maybe ! If you fly in tropical, ecuador areas, humid, a lot of insects, but even that , again no bugs above the canopies. And , bugs when smashed they get sticky, with no water.. just a scrapper is it efficient? Really don't understand the need of this, except for pilot psichology .
1. i think you have no idea, how much bugs on the leading edge make the performance of a ls3 worse. glide ratio and! handling . 2. i think you have no idea, how much bugs go up with thermals. what do you think why swallows fly high in good weather. (if you see the litlle birds under a cumulus... there is the best thermal. strongest thermal... most insects ... best meal ...most swallows) . 3. bugwipers on a ls3 ... totally senseful .
That's why nearly every new competition sailplane produced now comes with integrated bug wipers - just for pilot psychology :-) - think you have a lot to learn about biology, nature, meteorology aerodynamics etc. etc. l/d of ls3 measured at 41.8:1 with clean wing, 34.4:1 with 20 bugs/ metre........
@@soaruk3697 don't underestimate anyone behind a nick. I'm an Hang Glider pilot since my 16, I've 44. Flown in many countries and different continents , shared the sky with sailplanes. So.. I do know a bit of meteorology, and biology... my comment was is it a hype for sailplanes, like leather seats in cars ? Again, sworms of bugs are not common high in the sky like I said I've landed with many spider webs, flown under , around many cumulus... but smashed bugs ? Maybe they crashed while landing or takeoff near the airfield . 20 bugs /m2 ?
@@NoTengoIlusiones I've been a sailplane pilot since I was 14 am now 60, flown in 5 continents and several championships, officiated at world championships etc. and you obviously know jack shit about sailplanes and soaring, so to I'd stop commenting before you make a greater idiot out of yourself. Stick to your rag and tubes..... you don't fly as far, as high, or as fast, to have a clue what you are talking about.
@@NoTengoIlusiones It's really simple. All of us who fly gliders have had to clean the bugs from the wings after every long flight. In Europe, in Africa, in the Americas. Sometimes it's quite a task, as there are so many. And it has been measured how they affect performance (the measure is bugs/metre, as what matters most is the leading edge of the wing). There is nothing "psychological" about it. And, if you cannot imagine that you'll smash a ton more bugs doing 170km/h than you do at 20km/h, then you have way less experience than you claim.
Ich weiß, dass du ne relativ leichte LS 3 erwischt hast, aber trotzdem schonmal mein Beileid an dein Team das dir immer beim Auf- und Abrüsten helfen „darf“ 😂😅 The Blei is calling
Du machst immer soooo geile Videos irgendwann will ich auch mal so wie du sein ich fliege seid 4 Jahren und bin seid 2020 Flugschüler bin 13 vielleicht sehen wir uns ja mal beim Wettbewerb oder so nächstes Jahr kann ich mit unser hph 304 fliegen dann kann ich schon strecken fliegen LG Emil
Why the hell should it be? The LS3 wing profile is very sensitive to bugs. A few of them on the leading edge and your performance and glide ratio will drop like a stone. Especially when flying for maximum performance or at competitions like Stefan just a few percent will make a severe difference. So this installment is quite sensible!
That's why every new sailplane produced now comes with integrated bug wipers, or do you mean this particular bugwiper manufacturer? Maybe qualifying your response with more detail would help.
Bugwipers are no waste of money if you do serious cross country flying or comp flying in Germany. On some days they are a gamechanger. There are also manual whinches available which are a lot cheaper or you build them on your own.
love the part when the Guy from Leon-Tech introduces himselve and 99% of the world population including most Germans have no idea what he is talkin about. But Austria rocks ! Keep it this way, thats why we love you.
He looks like he really likes his jobs. Thats how life should be
I am not even german but I have learned german and I think he spoke very articulate and was easy to understand.
Still very happy with my LS3 after 30 years .
Why not keep the wing foil clean and wipe down with a silicone to prevent bugs from sticking. Also. Bugs will be close to the ground. Would not think there would be as many up higher causing drag or changes to the air foil so much.
Bugs are from the ground to the top of thermals. So, everywhere a glider flies.
Because no bug coating is perfect (and silicone needs to be re-applied, has environmental impacts, is more labor intensive). And yeah, bugs are mostly close to the ground, which is exactly where you take off from. So you need to wipe off the bug juice after passing through lower altitudes.

So how much glide ratio points does it take you when there are maybe 10 bugs on each wing? The BWS is also producing drag...?
It’s enough drag that the old glider computers used to have a bug setting. You could tell the computer how much bug contamination you felt the wing had and the computer would downgrade your glide performance. This was before bug wipers.
Drilling holes in your sailplane must make you very nervous until you see the beautiful results!
Bugs? We're really in trouble - when driving in NZ we see far fewer bugs than a couple of decades ago. Is it the same when flying?
What is the benefit when you take into account the additional weight from the motors and batteries?
I'm no expert but would assume very little impact. I think the LS3 has water ballast anyway but not sure if Stefan flies with it.
Also I see this on the Wikipedia page..
"In spite of its weight the LS3 is a nimble climber. It is also less sensitive to rain or dirt than other types with the same [wing] profile."

Nice!!!! You inspired me to become a real life glider like you. I fly the ask 21, thank you!!!
Did you custom mold your instrument panel or did you purchase it?
Wirklich cool, dass du auch solche Videos hochlädst👍🏼
What material is this spar, how thick is it, etc etc etc
Very cool! Although I'm so pleased we don't need them much in NZ. The bugs are way worse over there aren't they Stefan?
Yes, in NZ you only have salt on the leading edge 😂
Here in Europe it can change from day to day. Some days I fly with bugwipers, other without
Lord knows we need them in buggy Florida 🤣🥴
Your my favorite youtuber
One might almost think that with all these upgrades he´s increasing glide ratio😂😎
He is when the wing is buggy..........
More like restoring the glide ratio
@@florianeiser6084 depends if the bug wiper wipes all the bugs :-)
The stickers are only drag, I need to compensate it 😂
Woooooow nice plen
about price?
The serrated washer on the switches should be behind the panel, and the plain one in front.
Are you sure? I thought they were to stop the nut coming loose.
@@passenger6735 They are to stop the switch rotating when you tighten it if you have a single nut, or to stop the rear nut coming loose if you have dual nuts.

The wind resistance pushes them outwards when the cable loosens
