#BIRDY #Glider - Věda a technologie
This is a an exciting development in affordable environmentally-friendly recreational aviation! I look forward to more from you on this Stefan. You do great work.
Your channel is really getting good Stefan!
it's not only about POV flying, but it's also about you and your adventures before during and after flying which i love to see.
Keep it up!
Thank you for the encouraging words!
Danke für deine Berichterstattungen! So bekommen wir Zuhause auch Infos von der Messe. Weiter so. VG
Thank you, Stefan - very interesting glider concept!
The Birdy project is really fascinating! I am following it since some years. Thank you Stefan for giving us an update, in particular for everybody like me who cannot join the Aero this year!
Would be cool to compare it with your Silent 2!
@@SteFly So is this glider capable of taking off or just sustain power?
I love the utility of the pusher prop in the tail, doubling and replacing the spoilers!
Thanks Stefan. This was what I waited for. Minimalistic and simple. Only issue now is how much does it cost.
Yes! Enjoying your channel Stefan and would love to hear more about the Birdy EMG
Nice work Stefan, love the content
Cooler Einblick ins Heckpropeller Konzept👍 Gerne mehr Infos Stefan🙏 Gruss von den Kanaren☀️🏖
Danke 🙂
Dankeschön, Stefan! Deutsch engineering at work again! Cheers to you from the States.
🇺🇸💛🇩🇪
A step in the right direction.
I'd still want thin-film solar cells covering the surface of the glider so that it can be used for touring in places that do not have conventional electrical power available.
Here at this glider it will be really difficult due to the strict weight limit at 120 kg... but of course it would be great!
@@SteFly Why not deck out the trailer with the solar cells and possibly a batter bank instead?
Eric Raymond Solar-Flight
The weight would negate any benefit on an aircraft of this nature.
@@sillyoldbastard3280 NO. 1-2Kg is not going to harm how well you fly and still get you meaningful recharge where you could not without.
Finally an ev that not only is sensible but it really does fly well done
Wow, fantastic! Would love one of those to fly from my home field.
you can literally take it home with a friend. amazing.
thank you stefan i enjoy it
Hi Stefan! Really inspirating material & video! I really appreciate your english skill! I've never seen this project. Birdy is for me absolutely new way of gliders design and just look into the future :) Thanks so much for this video!

Hi Marcin, thank you so much for the comment. I will try to make my 120 kg ultralight license soon, so I can testfly it.
@@SteFly and moreover a lot of other gliders! Good luck! :)
An innovative and interesting design.
Would also love to hear from the Geiger guys about what applications they have envisioned for those larger motors.
These are the most exciting and innovative design developments in a while. This glider might never win a race, but not all gliders should be compared to racing gliders. Compared to most other light aircraft or TMGs a 200 km vne is impressive. and 30 KW from a 4,7 kg motor!
One cannot compare an electric motor to an internal combustion engine. One has to always include the fuel tanks and the batteries for a given mission.
Problem being the energy isn't in the motor... it's in the heavy batteries you need to power it. We won't surpass the energy density in petroleum products in our lifetime.
@@sillyoldbastard3280 although the thought is quite seductive. Imagine an energy carrier with 10kWh/kg and a motor with almost 10kW/kg.
Unfortunately any battery chemistry imaginable will not even come anywhere close to that.
Maybe a fuel cell will one day, but not if it needs pure hydrogen.
@@sillyoldbastard3280 well not mine but my 17 yr old very well might see that.
@@sillyoldbastard3280 Jet fuel is 50x more energy dense than a lithium batteries
let's see more about this!
Maybe you could get a test flight and record that for us,that would be very interesting especially the landing with reverse power............................
Yes, let's see you give it a flight.
I would like to hear more about total cost of ownership, cost breakdown, takeoff distance.
Thank you 😊
Great video Stefan. It is remarkable how far technology has come, to develop such a light electric motor glider. I would love to know, launch options, climb rate in nil wind etc. Thanks
I´ll need to test it on my own and see how it performs.
Definitely interested in knowing more about the Birdy ultralight glider., thanks
Yessss!
Sorry 😅 I obviously meant that addicional infotmantion will be great to hear
It's amazing work
Yes, let’s see it fly😎
Yes will like to see more about it please
If I didn't already have my Silent 2 I'd certainly consider one. I like the convertible top. The 2hr endurance on electric would be great if true. The folding prop may windmill enough to stay open and provide adequate drag for approach. I expect the motor would have to supply significant braking/regen to stop the prop for folding. I doubt very much that it is reversible and even if it were , the lag in going from forward thru folded to reverse would make it impractical for glide-slope control.
It's a glider. So the motor is not running in the pattern. The flaps would probably be the primary way to increase the rate of descent. I'd not want to rely on the motor when landing.
This is cool glider - please do show some more.
I've used the prop as an air brake on my rc gliders for years and it works really well, all it needs is enough throttle to open the folding props and then the drag slows it all down.
You said the props reverse on this, is that correct?
What price would these be?
Very good video!
Thank you!
Definitely want to know more!
@Stefan Langer: I'm a new viewer and subscriber after just finding your channel. As an airline pilot by profession, I also fly helicopters, gyroplanes, paragliders, and other aircraft. This section of aviation is intriguing me more and more. Could you do a video, or series of videos about how to start gliding, what aircraft are good beginner gliders to purchase, weather conditions to be aware of for beginners, danger signs, how to switch your mindset from powered high-performance aircraft to gliders, and subjects of that nature? 😎👍
wooo!! que genial sería pilotar uno de esos!!
Yes please more electric gliders!
I would like to know if they have plans to put solar panels on the wings?
I have not heard about it. Most probably the weight limit of 120 kg would not allow to install solar panels.
@@SteFly Seems if companies worked together the solar could be integrated into the wing structure without causing much weight difference. It's been done for RC for sure. There are already spy gliders with such capabilities I am sure.
Nice one
I'd like to see an FMEA for using the electric drive as the speed brake, it requires the complex system to function vs the simple mechanical spoiler. The spoiler function, if not available, can be compensated for by flying uncoordinated at the cost of higher pilot workload, so it may be acceptable.
Progress everywhere. I like their approach. The parachute to save both human and machine should be mandatory on all gliders according to me (I get that overall weight problem is a thing but priority to safety).
Gliders are cheap. Even with a parachute, it’ll hit the ground at a vs high enough to break it badly. Might as well confirm pilot safety and not effect performance with a parachute. Avoid parachute requiring incidents in the first place really.
Absolutely very interested.. would be nice to see you test flying it.
Yes please wow, also if they would produce a side by side 2 seater would be something super special
Is the Birdy going to be my return to Ultralight and Glider ? You tell em Stefan (thanks for the shared video) Friedrichshafen defenitely is an interestign spot
Wonderful.
I am interested to see more about the Birdy
Go Birdy!
Yes, more info please!
Thanks Stefan, really interesting... I would like to see how much the kit will sell for?
very nice , ciao dall'italia-
Cool project but I don't like tail. It adds a lot of difficulties for take off and landing! Solution without spoilers is interesting but what if you don't have any power in the batteries? Glide performance is impressive!
it would be nice to here more details Thanks
Excelente My friend
Would be great to see more about this glider...
Schönes Video über ein gutes Flugzeugkonzept. Was ist die Gleitzahl vom Birdy?
Danke Stefan für das Video. Den Birdy verfolge ich auch schon länger. Es ist ein total spannendes Konzept und ich denke der Segelflug wäre gut beraten, auch mal etwas mehr in die Richtung 120kg Klasse zu schauen. Fliegen ohne Medical, Eigenstarter und vermutlich völlig allein handlebar und das alles zu "normaleren Preisen" sind in meinen Augen sehr viele wichtige Argumente die sicher dem Zulauf des Segelflugs nicht schaden würden, wenn man sich nur die Zahl Lizenzinhaber Segelflug vs. UL anschaut, kann größer, teurer, usw. nicht das Ziel sein.
Danke Michael! Das sehe ich genauso.
Amazing
Interessantes Projekt. Für den Leistungsflug ist es zwar sicherlich nicht so geeignet, aber für den klassischen Renter mit genügend Kleingeld bietet es doch wesentlich mehr wie andere UL´s.
Richtigen Leistungsflug macht eh nur ein ganz kleiner Anteil der Segelflugpiloten. Unkompliziertes fliegen und der Spaß steht meistens im Vordergrund. Vermutlich kann man damit auch beachtliche Strecken fliegen, ähnlich wie jetzt mit der Clubklasse.
Very interested in hearing more
Very nice.
Scary when weight saving trumps secondary safety . Air braking when the prop fails might have to be a Ballistic
Parachute , lighter and just as safe …
Tell me more about this glider. How long to charge? Payload? Glide ratio? Comfort? Motor sound level in the cockpit? Automobile towing requirements.
i love it
Show us the ATOS air glider please !!!
Diese neuen Konzepte bringen meiner Meinung nach den Segelflug wieder zu seinem Ursprung. Federleicht und Spaß pur. Das größte Handicap ist wieder einmal die Bürokratie. Ich mit einem SPL mit Hilfsmotorstartberechtigung darf zwar bis zum Arcus alles fliegen aber nicht diesen kleinen Elektroflitzer. Ich habe einige Wochen die Silent 2 Electro (mit österreichischer Sonderzulassung) probieren dürfen. Hätte ich die finanziellen Mittel, wäre das für mich das ideale Spaßflugzeug. Ich habe auf meinem CZcamskanal schon 14 Follower. Vielleicht werde ich, wie du, noch zum erfolgreichen Blogger und die Hersteller reißen sich darum mir solche Fliegerlein zu Testzwecken zu überlassen;-))
Ist wirklich schade, dass man dafür erst einen neuen Fluschein machen muss. Vermutlich ist das aber nicht sonderlich schwer und auch die Kosten sollten sich in Grenzen halten.
Getting near a Hang Glider ATOS 😀
I'm, probably, wrong but I use airbrakes to reduce lift, not speed. It is kind of scary to dive towards airfield with propeller basically working as a parachute. Sounds like acrobatic.
Absolutely more
Beautiful! ...can we see it fly?
Does anyone by any chance know for what price these are going to sell new ?
Finally electric!
Wow👏👏👏👏👏
There's one revolutionary ultralight type of glider you would really enjoy: hang gliders ;) from 19kg up to 45kg
Must be a lot of fun to fly aswell! I would love the freedome of hike and fly with a paraglider but with a hang glider you have also a lot of trouble to get in the air...
@@SteFly have a look at the VR sim for HG called The Free Flight Experience by Thomas Low, built on Unreal Engine with global map like MSFS.
On the "trouble", it takes less time than sailplanes. You can hike with a Finsterwalder-Charly Airfex, breaks down to 1,85m. Single surfaces can setup in 10min plus 5 for harness and camera maybe. Paras may do it in 5-10 but they sit chatting waiting for thermals anyway, in the end we take off together, even topless gliders that may take 5mins extra.
Comparing both... PG is good on ground, HG better in the air ;) PGs float, feels like flying on an inflatable couch, while HGs fly like a bird.
If you were going to live in the sea, would you rather be a jellyfish or swordfish?
Have I mentioned cheap? A new fex will cost you 4.5k eur and last 2-3+ decades of flying, then you swap the sail and keep gooing. PGs cost more long term!
@@SteFly just think about it, for the price of an "affordable" sailplane you can get 10 gliders, a van, and fly with a bunch of friends who can't afford it.
No spoilers, counting on the electric system to always work, and always have enough power to create enough drag for a normal descent and landing. I don't think so. Great video anyway, thanks!
The early ASW12's had no speedbrakes. Once under a big strong cloud near the cloud base it is very nerve wracking not to be sucked into the clouds and stay VMC. Seen the claimed L/D of 40 the speed will rapidly approch the Vne in this situation.
Nevertheless the complete concept is brilliant.
Nice
keep safe❤❤
Not sure about that huge shaft sticking out the rear.
Looks crazy even without the prop.
Danke für deine großartigen Videos, ich bin selbst leider noch nie in einem Segelflugzeug mitgeflogen, aber deine Videos wecken in mir immer mehr den Wunsch es auch mal auszuprobieren. Hab auch Condor 2 für mich entdeckt mit VR Brille, das macht auch schon viel Spaß, ist aber natürlich bestimmt nicht vergleichbar mit einem echten Flug. Viele Grüße, und mach weiter so, und allzeit gute und sichere Flüge
Na dann einfach google maps aufmachen, nächstgelegen flugplatz suchen(gibt's wie sand am meer) und hinfahren! Gastflüge gibts immer und im Verein ist ne Lizenz günstiger als viele denken. Vor 4 jahren habs ich auch so gemacht und heute hab ich nen schein und nen Sonnenbrand vom fliegen ;)
@@120031770 Danke für deine Antwort, leider kann ich aufgrund beruflicher Verpflichtungen das noch nicht machen, aber meine Zeit wird noch kommen das ich mir den Traum erfüllen kann, darauf werde ich hinarbeiten, viele Grüße 🙂
awesome
Tell me more with the glider assembled. Price? What license do
I need to fly it?
i love it! id love something like this but i think it should have spoilerons, surely that wouldnt add much weight
It´s available with spoilers aswell.
@@SteFly nice!
what useful load can it carry ie pilot weight the long shaft would have loss of power
WORLD BEST INVENTOR 🏆DO MORE INVENTIONS🛩️BEST OF LUCK❤
how much does the motor + batteries weight? a twostroke + few liters of gas is smaller, lighter and has better mpg
Great
Yep, would love to see it flying. Another question... is there no horizontal stabilizer?
I guess it goes on the top of the tailfin.
How much weight would a parachute add for the glider?Seems like it should be mandatory. Would give great peace of mind.
Nice...
Wow. Brilliant. More please!
Slide slip is easy enough to master. I’ve used it to align a light aircraft back onto the runway heading after a strong late crosswind pushed me way off track. All glider pilots are taught it I thought as part of their landing procedures. I certainly was, way back in 1976 when I first got my glider pilots license.
@@knowledgebyte yes, side slipping is taught to glider pilots - as it may be crucial to getting into a small field when “landing out”
Wieviel Höhenmeter können mit einer vollen Batterie erzielt werden?
Gibt es PV-Paneele?
good view
I´m pretty disappointed, because its not possible to get useful information from the manufacturer or the investors. Same information on the HP since 2 years, no actual prices nor delivery time. No technical details. I gave up. Thats not the way to promote a new electro sailplane. I either want to sell an airplane or I don't. It seems to me that they don't want .
There is no glider manufacturer out there who publishes the prices and delivery times on the homepage. If you really want to get these information you will get them.
And of course it is a small team and their main focus is not marketing at the moment...
@@SteFly I tried to contact them via email and Phone. No reply. Finally I found an investor who told me, that the manufacturer is to busy to answer any questions. No comment.
@@ackerflieger6703 maybe they're busy developing something cool right now and don't want to respond to grumpy emails?? 🤷
@@cabanford I'm a potential customer and not a grumpy email writer. With Schleicher or Schempp Hirth you get reasonable answers within 2 days. There is another german sailplane manufacturer who makes the same mistake, great products but wrong company policy. And the result?
@@SteFly Hope you keep us all updated on this one! I too tried emailing my interest, but no reply. I'll keep hoping from over here in Canada. thx again for the Vid! cheers, Pete
Would love to see a test flight. The lack of airbrakes is interesting - if there's any problem with the motor, then you might get into difficulties with an outlanding.
It's electric so extremely reliable
@@gregb1599 so are sat navs till they fail !
Any glider pilot knows how to sideslip, which is the alternative if your airbrakes don't work, so I'm not too concerned about that. I remember during my training in the 2 seater, on one approach I found the airbrake was completely jammed, and I had to sideslip it into a landing. I then discovered that the reason the brakes were jammed was because the instructor had his foot on the lever, just checking me out to see that I could cope without them.
@@uproid This is true although modern gliders like this are very slippery - I wonder what the sideslip does to the glide path, would it get the L/D below 10?
@@colinjacobs176 It's really a forward slip which is my favorite maneuver because it seems so naughty to cross control. I forget the steepness, but it certainly can make noise when airflow goes non-laminar. I always wondered what happens if you alternate the controls back and forth to play with the lag of laminar flow.
Olá! Estou impressionado ! 😍 1001possibilidades de felicidade
You should explain that the glider needs only a few kW of power to maintain level flight at about 1.3 x stall.
Around 3 kW for level flight, that´s insane!
does the prop as brake.. also regen the battery?
Sounds good , as an ex aerobatic glider pilot i don’t like the idea of no aerodynamic brakes , the engine reverse Is ok but once you end up with no battery loosing brakes doesn’t sound great., 😊
Yeah let me fly it to work
THAT IS A VERY INTERESTING GLIDER!! DOES IT CLASSIFY AS AN ULTRALIGHT IN THE US ? (NO PILOTS LICENSE OR MEDICAL REQUIREMENTS )? CAN YOU ARRANGE A FLIGHT AND DO A VIDEO I'D LOVE TO KNOW MORE!!THANKS GREATWORK!
Not sure about the US regulations. Here in the EU we need a 120 kg ultralight license but no medical.
First I will need to get the license... costs some money but it's the plan
120kg = 120 x 2.205 = 264.5 pounds. The part 103 ultra light weight limit is 254 pounds. However if equipped with airframe parachute the weight limit is lifted to 278 pounds. So if a chute can be added for less than 13.5 pounds it might be possible to be a part 103 vehicle. Note part 103 vehicles are not classified as airplanes. If over weight for part 103 then you will need a glider ppl, which is not the end of the world to obtain and good education. I think the most important piece of info is the cost, I might have missed it? What does it cost?
He did answer the "About" price, in a reply I read, above!
So, "About €60,000!"
@@robertweekley5926 wow 60k would be great. Sign me up. Can the wings be removed/folded so it can be stored in a trailer? That is a big cost savings as in the USA T hangars are hard to find and increasingly expensive.
