- Is this the future of gliding? Electric self-launching system to get into the first thermal and to prevent from a land out?
I tried to fly 1000 km but unfortunately I used the motor for 2 minutes after 891 km of distance.

#AS33Me #glider - Věda a technologie
Hey Stefan, I just wanted to thank you so much for getting me into gliders. I finished a course in Colorado and am officially a certified pilot this last weekend. Wouldn't have even gotten into gliders if it weren't for your channel.
Hey Jason, that's awesome to hear. Congrats to your licence and I wish you many great flights!!
@@SteFly Now that's nice to hear isn't it?!
Hey Jason where did you take your classes? looking into getting into this after realizing 172s and other single props are insanely expensive to fly as a hobby.
It's pleasure to see following you generations with you. That's awesome. Best of luck.❤
Thanks Stefan. Electricity is the future. I am looking forward to a good modern two-seat self-flying electric glider. Too bad Dr. Stemme Elfin's project seems to be over...
For a two-seater glider the weight to thrust and battery capacity ratio is still not good
- Подумал - надо бы Игорю дать ссылку на это видео. А Игорь уже здесь :)
NO Electricity is one solution for the future their are other options out there............
@@buzzinbritain8222 a turboprop would be amazing haha!
Was für ein geiler Segler. Danke fürs Mitnehmen .Stefan.
sweet ride, thanks for taking us along.
Appreciate your comment!
I have at the least 300 hours in the AS33 ME in MSFS 2020. Love that thing!
Today i also did my 55 km run with that Thing and its so much fun
Wow awesome! Then you might be the one with the most flying hours on this new glider :D
@@SteFly I love that sustainer, it all ways makes sure that I am safe and a lot less likely to make an out landing. After 300 hours I hardly ever use the sustainer anymore, but its nice to know that I have it. Would love to fly one in real life one day.
@@Tomfriendly9000 in real life - don't ever forget that the motor may fail at the worst possible time, or not start at all, or worst yet, start, run, and then fail moments later. And when it fails, you can be assured its likelihood of stowing/retracting is 10%. So as you practice on MSFS keep this in mind. Maybe even do a few engine extended outlandings. The electric is far more reliable but I know personally of some failures with electric systems.
@@TheSoaringChannel And there is the risk of an electrical fire. This is dangerous in an automobile. Imagine in a glider in flight! The batteries are inside the wings!
Exciting development!
I can't wait for the opportunity to fly this 33 Me! I love my DG but I loathe the 2 stroke danger.
Electric propulsion is the best solution for a glider.
It's a great solution!
If battery's is not on fire! God save !
Love mine
Yay more videos to enjoy 🎉
Schön dass andere Hersteller auch endlich auf den Trichter kommen wie Lange schon vor 15 Jahren. Da wurde er noch ausgelacht. Ich liebe meine Antares, die scheppert auch nicht so, wenn der Motor läuft ;-) Aber die AS33 ist schon ein schmucker Flieger 👍
Ja....; das "Scheppert" auch in meinen Augen bzw. meinen Ohren.... = keine Ahnung wieso ein Geräusch wie rauher/unwuchtiger Lauf
Speak about the future !!! 😊😊😊
It's the present!!
Well done on qualifying. I flew in my pure 29 in 2012. Don’t need an engine, just big balls😂
Thank you!!
fantastic
Cool! I landed on Bayreuth a few weeks ago (PH-588, BU Mini Nimbus) when I could not find any new thermals, and saw all these trailers and found out there was the German nationals going on.. Reluctantly they offered me a tow so I could fly back to my home base at Saal Kreuzberg, but I had to leave ASAP because in 30 minutes the first competition gliders were expected to come back... But the guys were very helpful and I was in the air again in 20 minutes or so, found a thermal and managed to get back home.
But what a cool plane that is the AS33 Me, if I ever win the lottery, maybe this will be my next plane.. For now I enjoy my Mini Nimbus, still going strong and flying competition in club class (coming weekend Amstelglide from Soesterberg)
Very cool! Flying club class is also so much fun. Just made a 900 km out and return flight last weekend with my LS3. Still amazing what is possible with these old gliders!
Nice. The lever power control is more intuitive than Jonker's rotary power knob.
Love it! Easy to use and intuitive concept with this lever and the start button.
@@SteFly And is the tailwheel fixed or steerable? Fixed (as on a competitor's product) seems to be a bit of a negative to the traditional self-launching crowd, at least here in the U.S.
@@elkcircle7245 It's retractable but not steerable at the moment. Not sure if there will be an option available in the future?
@@SteFly So, like Jonker they are favoring the retractable feature for competition, and avoiding the performance hit from external steering horns and cables such as in the ASH31. And maybe also avoiding excess electric energy usage / heat accumulation in the batteries and controller from taxiing onto the runway and back to the trailer. That makes sense, but it's going to limit the usefulness of having a self-launcher that has to be towed to the launch point, particularly at airports shared with power traffic. It will be interesting to see how the electric market evolves. Thanks again for your overview.
@@elkcircle7245agreed!
Hats off to you and pilots like you. If you wanted to go city to city do you have to go with the wind or can you go cross country in various directions? Cheers.
We don’t use wind we use thermals, we can fly in all directions
Forgive me as I know nothing about sailplanes, but what is the device, shown at 6:48, that slides outboard & inboard on the wing leading edge? Is it some sort of weight?
Bug wiper. The bumps from the smashed bugs disrupts the laminar flow over the wing so cleaning it up help performance.
You get dead bugs on your wings when you are flying and especialy a sailplane needs for the highest performens wings with out any imperfections. Thats why they install a bug wiper system which is what you see. It has one or multiple strings attached as it glides over the wing and removes a lot of dead Bugs so can fly further.
How much do these cost? Been weighing getting my sailplane license. Normal ones I see for roughly a car...
C'est cool
Love that glider! I wonder who the US sales rep for the glider is?
I´m not completely sure, might be Williams Soaring Center. That's where we got some spare parts for the ASG29 when I was in the USA last year.
Hey, Stefan. Danke für das informative Video. Der elektrische Selbststarter für Segelflugzeuge ist viel zuverlässiger und umweltfreundlicher als jeder Verbrennungsmotor. Aber das Segelflugzeug verwendet eine gefährliche Hochspannung von 400 Volt. Da sich die Batterien in den Tragflächen befinden, erfordert der Auf- und Abbau nun mehr elektrische Sicherheitsmaßnahmen. Auch das Öffnen der elektrischen Propellerklappe bei Regen wirft zusätzliche Fragen auf. Wie wäre es mit einem neuen Hochspannungs-Sicherheitsvideo.
Just saw the video and have questions. 1-what is the weight capacity to get the certificate for it. 2-How long can one of tbbem fly on one tank of gas gojng from gliding to motor and back.3- What meds disqualifies you from getting the certificate.
Why did you set the flaps to 6 before landing? They were in the L position but you changed this during final. How is the handling in 6 compared to L? Does it feel similar to the ASG 29?
I encountered some sink at final and decided to switch to flaps 6, so that I will reach the runway. Flaps 6 and L are the same as at the ASG29
@@SteFly thank you for your answer :)
Professor Loek Boermans told me, that a condition with say 20% - or more lift over the distance allows to use the so called Dolfin technique. This increases the overland speed dramaticly. Sparcely turning in thermals, flying with different speeds using slight zig zag. The "kurbel anteil" (amount of time turning) in a ka 6 is mostly 50% an this part has no overland speed.
what kind of cost are we talking here? also is there a dual cockpit option?
How much does something like this cost and what are the regulations on flying one with a regular pilot's license
Having flown the latest ships, which was the most memorable? If you were to buy one, what are you buying and why?
I love 18m gliders and electric self launch gliders. So the selection would be between JS3 RES and AS33 Me. Both have their pros and cons. AS33 Me has the best ergonomics in the cockpit and some luggage space to travel by glider; the JS3 RES is lighter and you can remove the batteries for charging.
Chill.
Very nice. Question: can someone explain why he carried 100 kg of water?
The glide ratio is a given value at a given speed and given wing loading in calm air. If you add water you keep the same glide ratio but at a higher speed.
That's the reason we put water in our wings.
how much drag would the motor create if it was left up throughout flight?I'm thinking of retro fitting?
A lot, it is in short an airbrake. If it doesn't retract it can't go far from the airfield
David Williams and Fred To flew the Solar One solar powered glider maiden flight on 19 December 1978. It's a not new idea and it's much easier and better now.
What are the things sliding in and out on the wings starting at 6:49? What do they do?
i guess it is a insect cleaner. to keep performance up.
@@moritzkeller4502 yes, it is. They are used to clean the wing's leading edges where dirt has most effect on performance.
Bugwipers!
@@vihai You mean, it is actually aerodynamically more efficient to have these things permanently on your wings, compared to having insects accumulate on the wings leading edges? Astonishing! I would never have guessed that and I have never seen these devices before. Thanks for clarifying.
@@virtualinfinity6280i believe there is a kind of hole in the side for the wiper to go in
Did you reduce flap on the final approach?
Yes... I was not sure if I will get to the airfield and decided to reduce the flap setting carefully.
6:47 Amazing! But what was that?
It’s a bug wiper, it’s useful during summer to clean the airfoil in flight
What was that black thing sliding along the leading edge ? 06:56
A bug slider to clear of bugs and stuff from the leading edge
30 kW. That's 40 HP. Insane. 😃
What is the device that slides along the leading edge of the wing???
Bugwiper
What is the price on this one?
I'm shocked how LOUD that thing is. Compare this to a 15 year old Antares which makes no noise at all.
If you don't like it, send it over to me in Bowland Forest. 😄
What was the name of your new variometer?
LARUS: www.stefly.aero/product/larus_glider_sensor/
Nächster Flieger nach der 29? 👀😂
Nice flight! A little disappointing to see the "pilon" for the electric motor. Compared to the sleek pilon on the JS3 RES, the AS33 looks like something a mechanic put together in his garage.... 🧐
Agree that the pilon of the JS3 RES looks better but at the end the most important thing is that it works. As33 also uses a bigger motor..
I did not know about the bigger motor. Thank you. @@SteFly
Do you know when the AS35 Mi will be ready to fly?
Heard rumors that it should fly at the beginning of next year! Hopefully someone will fly it next year at the worlds in Texas!
@@SteFly Thank you 🤙
Never had much to do with gliders. What’s the black thing sliding up and down the wing?
That's a bug wiper. Especially during the summer, a lot of bugs tend to crash onto the leading edge of the wing, ruining the aerodynamic profile and causing extra drag. What bugwipers do is scrape the bugs off midair recovering a little bit of performance.
Bug wipers are manually activated and can be found in the form of manual bug wipers where you have a little winch in the cockpit with the string attached, and you rotate a little lever to deploy and retract them, it's downside is that you're fighting against over 100km/h of air coming directly at the bug wipers, therefore, it takes time and some effort (you can see them on Stefan's ASG29), or in the form of electric bug wipers where the winch is connected to a switch and with that switch you can deploy and retract them, this system is more expensive but extremely easy to use, requires much less time and no effort (you can see them on Stefan's LS3).
Most gliders can be retrofitted with the system, but, not being built with bug wipers in mind, they will be sticking out causing extra drag and are therefore removed when there aren't a lot of bugs and aren't needed, while on the most modern gliders (such as the one Stefan is flying in this video) the manufacturers build the gliders with bug wipers in mind and they fit them as part of the fuselage itself, therefore they don't stick out when not deployed and don't cause extra drag, meaning there isn't any reason why to remove them.
@@Nico9472_ oh cool. Worked on gliders but old ones so never saw anything like that
What was the name of the new variometer you installed?
the digital one seems to be an lx9000
I was talking about the LARUS variometer: www.stefly.aero/product/larus_glider_sensor/
The one installed in the AS33 Me is an LX9070 without HAWK
Only thing we need now is solar panels on the aircraft to recharge the batteries and you could go for days!
11 MIn 40 Sek: Vario springt zwischen -1m/+5m unmotiviert hin und her...... = ich geh mal davon aus, dass die Bedingungen nicht soooo turbulent waren.... = wieso also diese "Herumhüpferei" ? = feedback bitte / Danke / MFG
Die Druckabnahmen befinden sich hinten im Bereich der Propeller Turbulenzen
When you charge the battery using solar panel or other renewable energy generator, gliding officially becomes almost 0 - carbon footprint sport (not taking carbon cost of production into account)
Perhaps put the solar panel on the trailer? 🤔
Where can I download your gopro mount from?

What would you think about putting solar cells on the win and reducing the batterie by 2/3? That way you would still have enough capacity for the self launch but the energy you can use during flight would come at a way lower weight panalty.
Sadly, there isn’t a cost effective production ready solar cell technology that could maintain the laminar flow on the upper surface. You would be wiping out ~40% of your laminar flow benefit on the wing. That’s a huge loss in glide performance. In strong conditions the weight isn’t an adverse effect, but rather a benefit in inter-thermal speeds.
Most likely to complex for the production and at the end you wouldn't safe a lot of weight.
@@kevinfinke6927 "Sadly, there isn’t a cost effective production ready solar cell technology that could maintain the laminar flow on the upper surface." All in all that should not be that expansive to build. But I can see, that it not being a thing (yet) could make it quite expansive to make it a thing.
about the weight: if you are below your desired optimal weight, that gives room to something useful with the freed up mass. So I think weight cuts are allways useful for something. Also you probably need some of the cut weight for the solar cells themself.
@@SteFly perhaps there is something I do not see. but integrating flexible solar cell while forming a wing does not strike me as that complex. Also my hintch is, that you would not only save weight, but you would have way more Energy over the span of a flight than your Batterie would have stored.
not to mention, if you have an outlanding and are out of energy, you would not be stranded. That strikes me as a worthwhile advantage.
@@MusikCassette If a launch to ~450 m uses 26% of the battery, I wouldn't want to reduce the battery capacity much, even with solar. Solar would also require a completely different wing compared to the non-electric / non-engined version of the glider, and would still be heavier than a combustion engine and enough fuel to beat its range. Engines like this are meant to get you to the nearest thermal, the last few kilometers to home, or to the nearest airport, not for long cross-country flights.
Using the engine to take off after an outlanding is unrealistic. Firstly, taking off from a Field is (I think) illegal, most out landing fields aren't big or smooth enough for a safe takeoff anyway, and waiting for your empty batteries to recharge would always be slower than having somebody pick you up. If you landed on an airport, why not use their power to recharge and/or get a tow?
What is with the LAK 17C FES 18m it is not the first self launch glider? I am shocked!
Is it already EASA certified for self-launches?
Well the first EASA certified electric self launch glider was the Antares 20E, by years. Now some 20E's came with an 18m tips options - but not sure if it was certified to self launch at 18m?
What are those black things moving along the wing?
Bug wipers to clean the wings for best performance. Very important here in Germany these days!
@@SteFly Wow I would never have thought that would be an issue, we are told there are fewer bugs due to pesticides here in the UK.
Qual o preco
Haste den Akku schon mal angeschaut? ..... Wild, das die Karre nicht abbrennt ist alles.....
Ich hab mich schon vor Jahren mit dem Thema befasst und kenne auch Vorträge der Firma die die Akkupacks herstellt. Da hat sich sehr viel bezüglich Sicherheit in den letzten Jahren getan und die EASA Zulassungsrichtlinien haben sich auch weiterentwickelt. Benzin ist auch sehr gefährlich und der Gestank die ganze Zeit im Cockpit ist nicht geil.
11:55 richtig üble resonanz getroffen mit dem Powersetting. Hätte nicht erwartet dass der Stromer so scheppern kann
Ja, die Drehzahl war nicht perfekt :D
how do i see all the flys still there after u let the cleaners out
Only the elevated parts are scraped off but this already helps a lot.
@@SteFly why dont they make it so its scrapes all flys off?
What landing strip is that? ICAO number ?
It’s a private airfield without ICAO number
Are gliders safe for high blood preassure people like comercial planes? Does the cabin have preassure control? Thanks in advance
Airplanes are pressurized to 10,000 ft but you won't go to 10,000 ft in this anyway so you'll be fine
Depends on where you fly. In the west we fly to 18,000 feet in our gliders all summer long.
Why can’t we release the heavy battery pack by parachute once established at altitude? Or have the battery pack glide down with pop-out wings and GPS guidance back to the launch site? It would save soaring with all that dead weight
That dead weight actually improves glide performance at higher speeds. We fill the wings with water to increase the glider weight and then dump the water right before landing.
I wish i'd just bought one of these instead of wasting the money on training and flying cessnas
What do these generally cost? I want one.
About the price of a Lamborghini Urus or so 😮
Um what the hell slid in and out on the leading edge?
That's a bug wiper!
What is that thing that moved across the leading edge of the wing?
Why does it sometimes flip and start turning in circles?
Wasn't it Axel Lange who took the lead, years ago already? The Antares, isn't it? It is CS 22 certified.
Initailly he fitted his DG 808 with the Antares engine and mast, and after intensive testing, developed a complete new super aerodynamic electric aircraft. It owns still some records.
The AS will be a comparable plane, I guess.
You can only compare if you have flown both.
Being a bit critical I don't understand why they didn't make the prop blades pitch adjustable, one could even use that as an adjustable air break so to speak. Now when the prop comes out it immediately produces a lot of drag. One could also use the prop as an active air break I guess, which turns the prop direction in the opposite way. Not sure if they've build that in? Don't find it a very subtle design to be honest. Probably very practical but lacks in smart design which could improve the whole concept in my opinion.
Sometimes the simplest solution is the best. More complex stuff can fail and is heavier.
As long as you stay in your airspace, do what you like. But ya slow us up in the pattern, your gonna know what wake turbulence does to a plastic wing
Too heavy empty.......... lacking the adaptability of the JS3 RES for competition - lets see what the Diana 4ER will bring ...................... cold be the '3 killer'.
All these gliders are a compromise, the same as combustion engine slef-launchers. AS33 Me is relatively heavy but has a good range and tested propulsion system. JS3 RES is more flexible with the two batteries and slightly less heavy, but has only about 2/3 of the range. MTOW is also limited with batteries.
Diana 4ER and other future concepts need to fly first and prove their weight and performance. Looking forward to fly them all!
@@SteFly The JS3RES can be flown at 600kg with one battery as a sustainer, and it is then significantly lighter than the AS33ME for competition i.e 50-55 kg. Flying a heavy 18m motorglider in competition where you can't easily remove the batteries wouldn't in my mind be a good idea - even Uvalde has weak days - when most competitions are won........
A self launch glider is just a fkn plane.
Yeah, I’m wondering what exactly the distinction is. Maybe something vague like “gains most of its energy during flight from thermals, not from an engine”.
You would not fly a machine like this for the purpose of travelling under power. The power unit is used to make it easier to spend time gliding. In competition, if you start the engine after starting the competition task the flight is treated as ending at that point. It doesn't have the range or luggage capacity for any transport purpose.
@@Mike-oz4cv Actually you are very close to the definition of Glider..Glider.means a heavier-than-air aircraft, that is supported in flight by the dynamic reaction of the air against its lifting surfaces and whose free flight does not depend principally on an engine.
Gawdawful loud music!
Shut the he # up and turn that beeper off...
Man you dont know shit about gliding
Hey Stefan, I see you've decided to play the part of a British gentleman in your reviews. An audacious move indeed, but regrettably, it seems like your theatrical venture may have strayed a tad off-course. Your attempt to pronounce "agile" in a posh British accent was, how shall I put it... rather unconventional.
Can I just say, as a German reviewer, embracing your natural accent could lend a unique and authentic charm to your videos. It might also help your audience to connect with you. The way you are doing this accent is just... distracting.
Do you think it is possible to deploy a tow cord to another glider, and pull to safety,🫡🤔🤔🤔
