it’s the only sport that makes me dream. and even more today. my first flight was in a wooden glider with my dad in 1967. spending time on airfields is what we did throughout our childhood and adolescence. glider passion is a virus. Congratulations about this one and thank you to share with us
@@kagefisk : they all were made from wood and cloth - once. Plastic fantastic is here for only, like, 50 years. What are 50 yrs, nothing. I learned to fly on a wood&cloth glider, too. Was a great experience.
It must be on the expensive side of gliders, but I love it's high tech dashboard. Also the electric propulsion is nice feature for gaining altitude when it's really need.
The point at this glider is, that the construction of it is already almost 30 years old. In fact its even older because the Ls8 is basicly a Ls6 with fixed flaps, so you can say that the glider is from the 80s. Of course the Ls8 became kind of a legend with the time because it flies really easy but though has a good glide ratio (should be about 44:1) . Also its one of the most used glider for competitions in the standard class besides the discus 2. So DG in fact builds a glider, which is more than 30 years old. They do only small facelifts (like the neo winglets and so on) on them. The gliders of them cant compete with gliders of today, but nevertheless they cost a lot.
yes, exactly. but its not just that its very nice to have electric propulsion for airplanes or glider, obviously electric motors and the use of electric power is more efficient and friendly to the environments. and also, the benefits of electric is that its less expensive and more simple, and also more powerful.
@@folkenvanvanel6611 I’m way late, but me and a few others will be attempting to make a glider like this with one seat, and we are starting to make RC models of this, hopefully we can make a full size model soon.
Most people don't own gliders. They join a gliding club and pay membership fees which entitle them to fly the club's aircraft. It's mostly volunteers that do the instruction and that's usually free. You just pay for the launch and a nominal hourly rate for the aircraft. You should check it out... it's a really great scene.
Try with styrofoam. Wrap it with some cheap carbon fiber substitute. And you might be able to take it up to the sky. And it promises to bring you down sooner or later in one way or other. 😁😛
I particularly enjoyed the extended battery securing aspect to this video. It's never given enough air time in similar features. I love watching batteries.
The batteries can be swapped and the flat batteries are charged while you fly. Way more fun than charging built in batteries when you can't fly for an hour or so while waiting.
Yeah, I think I wouldn't buy this glider too, because of all of that noise in the background as he said... too noisy... I'll stick to my new skateboard :-(
Almost nothing about is free but gliding is not expensive when compared to other sports. Most gliding clubs are run by volunteers ie. Members and may have only a couple of employees (usually instructors). There's also amazing rates for under 25's which can make the flying almost free, young people just need to be able to make their way to the airfield and you can borrow club gliders until you give up flying if you don't want to buy one. As with cars (also not free 😉) there's a second hand market and often random people buy one together and share annual costs in a syndicate. It costs as much as you want to put in to it. £50 a month can buy you an hour or more of flying and that's basically a cheap meal out for two with someone you really liiiiike
Thanks for the walkaround. What a beautiful glider you have! Such neat insturments and a full screen gps and presumably any kind of map. I love the electical system and with 20kW surely one could climb at several m/s. I went solo in England flying in K7's, a K10 (I think), then K8's. Great fun! I'd love to fly again!
It took my body a few flights to become used to the sensation but i've just logged my 17th and over 10 hours and I don't intend to give it up as long as I can keep it up ;)
Ausgezeichnet....Sie sprechen sehr gut English! Ich habe alles genoßen! Vielen Dank. Before I went to US Navy Flight School, YEARS ago, I flew Schweizer 2-22 and 1-26 Sailplanes...never had the chance to fly a Glasflügel. One fact: sailplanes make one a better pilot, at least for my sailplane experiences, I had no motor and thus had to have an excellent downwind, base, and FINAL....could not go around again!! Love this video....Wenn ich nur dort wäre!!
I started in a Switzer 233 like flying a pickup truck, It had air leaks all over and i liked the wind sound. When the sound stopped your were in a Thermal or in trouble. It was fun.
I was a passenger in one of those once. My friend did wingovers above the Flatirons in Boulder and I puked out of the rectangular side window in the back seat that flopped downward on hinges. No thanks.
The SGS 2-33 was my first solo...the only other gliders I've flown are the ASK 21 and PW-6U but compared to those, it flies like a pickup truck. Compared to the LS8 and other modern stuff, it must be closer to a freight train. Still, the Schweizer was always a good time...god knows my slipping skills got better because of it.
Literally first glider video I saw an hour ago got me thinking that it would be a nice addition to have an electric motor with a folding prop on one of those in case the pilot fails to find any lift. Then I thought that of course that would be a compromise on the gliding abilit, because of the weight so maybe it's not the best idea. Googled the weight of some glider, did some quick rough maths about weight, electric motors and energy consumption then realized it might not be such a bad idea. Literally a few recommendations later this video shows up and I feel validated lol.
Thank you for the interesting video: it gives a nice insight into the operational realities of a FES equipped glider. You make an interesting comment that the LS8, when compared to the '29, is the more 'communicative' glider regarding thermal structure and hence easier to core quickly. I was wondering how you would rate the Libelle in this regard?
The Std. Libelle (without winglets) is also very communicative but compared to the LS8 not so stable. You need to fly the Libelle more actively and it takes more concentration. But the feeling of the thermals was also very good.
Dieses Flugzeug ist sehr beliebt, Stefan, danke für den Einweisungsflug. Von einem so schönen Flugzeug würde ich gerne mal einen Selbststart ohne Schlepphilfe sehen. Der Lärm kann durch die FES-Kühlung des Elektromotors verursacht werden. Ich wünsche Dir einen guten Start in die Saison!
Nice review. I have to agree that the noise levels are way too high. I’ve flow I think 4 standard LS8's and none were as noisy. I’d suggest it’s caused by the unsealed battery box leaking and I’m surprised you didn’t tape it up...
Thank you for the video. That is one cool glider. I noticed you have a spot personal locator beacon on. I’m glad you have a beacon. But you might consider getting the ACR brand. There is a few reasons for this. One the ACR brand has no monthly fee. It also has 5 W of power. This way if you were down in the canyon or under a snow covered canopy it will have the power to get out where the spot only has 1/2 of 1 W. The spot also has a monthly fee. Finally the ACR brand is part of a worldwide search and rescue network that many governments are on board with and the ACR beacon will work anywhere in the world even the north or south pole. The spot uses a private satellite network and there are reports of the beacon being set off and them not dispatching search and rescue because they think it is not a real emergency. That is not an option with the other network. Also the other networks at ACR uses uses two different satellite constellations. Anyway just wanted to point that out beautiful glider thank you
The instrument panel is a state of the art panel with LX9070 glide computer and the remote stick is for user inputs to the glide computer in flight. The remote stick is neccessary, because my arm is too short to use the rotary knobs and buttons in a comfortable way. Both battery packs together have a 4,2 kWh of energy, which is max. 80 km range of pure electric flying.
@@SteFly Wow, just wow. 80Km is enough to prevent a lot of off glider port landings. Can you charge the battery in the glider ? What is the L/D on that thing ? How much drag does the prop add ? Is that where the cockpit noise is coming from ? Please do a video on that panel, both on the ground and using it in the air. Does it have a radio ? ADS-B ? What is the "Fire Warning" button about ? The battery system ?
@@SteFly Its an amazing efficient use of elektrickel energy. In comparison to petrol engines : 1kg petrol has 11kwh Energy in stock. No petrol sustainer can drive a glider for 80 km with 1l of petrol.
@@arminmoller9927 Well no. With the weight of those batteries in gasoline - this glider would fly across a continent. And it is 4.2kWh for both batteries combined. You can get a self launch, not a sustainer with the same weight.
@@SomeTechGuy666 The panel has a "air control display" its a combined Altimeter/Radio/Transponder controller. The plane for sure has a Powerflarm integrated into the LX Computer which features ADS-B in. The LD is 1:50 for 18m. Don't know about the drag.
I'd be very worried about accidentally pulling the NOAH system when I meant to pull the cable release ! What a fantastic glider. The cockpit looks cramped. Is it ?
There is a safety mechanism, so that you can´t inflate the NOAH system when the canopy is closed. The cockpit is not cramped, it´s comfortable from the space. Much bigger than an a-fuselage from Schempp-Hirth, feels more like the b-fuselage or the ASG29 cockpit.
@@SteFly Just stumbled upon your channel and know nothing about gliders, but when you were talking about the NOAH system, did you say that its to be used in the air so you can get out with a parachute??
@@MrJaxalope its a gas inflated cushion that lifts you to the edge of the canopy. You can then roll out of the glider and use your parachute. The system was invented due to people getting stuck during high 'g'.
wouldn't extend the range. Adding ballast extends range. Look up the glider's polar curve at different wing loadings. In any case you need tail ballast to shift the CoG back to the right position if you fly without the batteries.
Beautiful glider. Pity it’s so loud... probably the propeller blades causing rupture in laminar flow around the nose area? I wonder if they can fix that. Thanks for sharing!
@@yuan.pingchen3056 It's a fantasy. The need for a safe t.o./landing area will never change so apart from aerial taxis using designated areas it's unrealistic for mass implementation. I can't even fly my toy drone near people because it's legitimately unsafe.
Nice review Stefan, how do you have the time to create that many videos haha. This LS8 is a dream setup! - though would've loved to hear some range and performance specs on the FES system.
Thanks mate! Yes, it´s really time consuming to film and edit so many videos. Especially during competitions it is stressful. But now I´m back home and take some time to edit the footage. I had no time to make a proper range test only with the electrical motor. At one day I used 3,3 kWh and the battery was already fairly empty and the FCU said that I should reduce the power, even in level flight with 5 kW setting... So the reality is something between 60 - 80 km range in calm air. But most of the time this is enough.
If anyone is curious. Those 'screws' are commonly called zues clips/screws. Commonly used for quick on and off panel applications in the automotive world as they only take half a turn or so.

Looks fun. Wish we mere mortals could fly too but it's pretty to watch also. Thanks for the vid and the plane looks and flies great from what I see here.
The Versailles treaty banned Germany from having an airforce after ww1. Germany formed hundreds of glider clubs and trained a generation of excellent pilots who could easily transition to powered aircraft when they built the luftwaffe.
All the buttons, screens and instruments and still one of the most important gliding instrument is a piece of wool taped to the canopy! Nice looking ship!
Man, that folder looks CLEAN. I could see owning this...nooo problem. Would really like a self launcher, though, so that pretty up front prop isn't really the answer for me. Ridiculously nice panel, dude. Does the whistle diminish when you open/close the vent, or is that not a contributor?
I wonder if a few earthX batteries could do the job for less weight? Battery tech really needs to move forward to make electrical propulsion a more viable situation than it is currently.
Who makes those jet sustaining gliders? I saw a new product a while back that uses electric driven wheels for take off augmented by jet propulsion for flight. Can't remember who is trying to develop it yet seems a very efficient use of energy as wheel traction is far better for take off and requires power for only a 15 second burn allowing the battery to be small. Thereafter once up to speed jet propulsion can prevail with optimum efficiency.
@@JoshWeaverRC I found it then forgot to post it. www.proairsport.com/project-glow.php www.planeandpilotmag.com/article/jet-powered-glider/#.XYT46FRKiM8
@2:10 is a mistake. There should be detents which prevent too much tightening and more importantly, prevent them from working loose. A small weight shift may be enough...
Add some ultra light solar cells on the wing to top off the charge mid flight and you could do some amazing cross country flights with security to cross the big bad sinks.
Besides the tow-hook, what else is sacrified for the FES engine compared to the normal LS8? Can the rudder pedal go as far to the front, (the normal LS8 is not that big)? Is is still possible to put trimmweights behind the rudderpedals?
At the prototype the rudder pedal looses one step, so it is about 3 cm shorter. But in the next gliders they will change it and the full length will be available. Trimmweight should be possible, at least I had some trimmweights in the trailer. ;)
That's not that simple. It's very difficult to glue PV cells to the wings, which are very flexible on gliders. Then there's a problem with surface, again, glider's wings are extremely smooth, and, of course, there's the weight issue. I think there's only one practical (usable) solar powered plane out there: Sunseeker Duo.
fifi23o5, the wings may not be practical without significant engineering, but I suspect they could put enough PV cells on the fuselage to trickle-charge the batteries while it was on the ground.
@@Vessekx such thing is already in use on gliders. Some have PV cells on the doors of retractable engine and it is used to charge the battery for instruments. Fuselage doesnt have the area to be sufficient for propulsion..
fifi23o5, I wasn’t proposing the solar cells would be used to driver he motor in flight, simply that it could be sufficient to recharge the batteries while parked, rather than having to disconnect them and haul them across an airfield.
@@Vessekx That wouldn't be very practical. You could get 150 W of power at most from the fuselage. And cells would have to be flexible and very small due to tight radius of the fuselage, so it would take an awfull long time to recharge the batteries. So, if I fly today, land late afternoon, when would batteries recharge? No flying for a day or two. Just not practical to be worth the effort.
Nice glider but the lack of t/o capability kills it for me. I'm extremely happy with my Silent 2 Electro which never needs a tow thus allowing me to fly out of my nearest airport whenever the conditions look right. It also allows me to extend my gliding season by about 2 months as all the clubs here are on grass fields which aren't usable until the snow is gone and the field is dry. It would be nice to have the extra performance of an 18m but only if I could take off.
It looks like the batteries are either acid ones or AGM. Wouldn't it make more sense to use LiOn ones? They are more efficient and lighter. It's also a bit concerning that the terminal cables are not secured by anything to the batteries. It would make sense to use another bar on the top to secure them.
Having to use a screwdriver to access the battery compartment is very impractical. Especially for emergency access to the battery compartment in case of fire. Perhaps an aviation snap latch might be better. Relatively light, requires no tools and flush with air stream.
In case of fire, there's nothing in the battery compartment you want to access anyway. You can't put out Lithium batteries, just let them burn and have the insurance company get you a new plane.
He said the battery was from 15-20 kilowatts, the wing doesn't have enough dimensions to justify solar cells (would take days to recharge them fully, and you don't leave a glider like that out in the sun).
compared to taxi drones, I think this engine looks more efficient. but can't land and takeoff vertically. maybe with more research, this machine will be future transportation.
I don't think that gliders will get commonly used aircrafts for transportation. It is awesome to fly them as a hobby pilot and they are very efficient.
camtwan1 I like the idea of the folding prop, but the electric motor on a lid that folds out above the wing would be cool too, kinda like rc power gliders.

@@SteFly Its an amazing efficient use of elektrickel energy. In comparison to petrol engines : 1kg petrol has 11kwh Energy in stock. No petrol sustainer can drive a glider for 80 km with 1l of petrol.
@@arminmoller9927 Well no. With the weight of those batteries in gasoline - this glider would fly across a continent. And it is 4.2kWh for both batteries combined. You can get a self launch, not a sustainer with the same weight.
@@SomeTechGuy666 The panel has a "air control display" its a combined Altimeter/Radio/Transponder controller. The plane for sure has a Powerflarm integrated into the LX Computer which features ADS-B in. The LD is 1:50 for 18m. Don't know about the drag.
You could use the wind flow to drive the propeller which then drives an alternator generating its own constant free electricity.
I'd be very worried about accidentally pulling the NOAH system when I meant to pull the cable release !
What a fantastic glider. The cockpit looks cramped. Is it ?
There is a safety mechanism, so that you can´t inflate the NOAH system when the canopy is closed. The cockpit is not cramped, it´s comfortable from the space. Much bigger than an a-fuselage from Schempp-Hirth, feels more like the b-fuselage or the ASG29 cockpit.
@@SteFly Good to know about the NOAH canopy lock out.
@@SteFly Just stumbled upon your channel and know nothing about gliders, but when you were talking about the NOAH system, did you say that its to be used in the air so you can get out with a parachute??
@@SteFly Yeah, having spent most of my single seater time in SH gliders, I'm envious of all the space in this one. And the side pockets! :).
@@MrJaxalope its a gas inflated cushion that lifts you to the edge of the canopy. You can then roll out of the glider and use your parachute. The system was invented due to people getting stuck during high 'g'.
Somehow it should be possible to drop the battery when it is empty with a parachute away. Maybe motor aswell.
I can just imagine going to retreive it from some unsuspecting homeowner who saw it parachute right down through their window....
launch with the electric prop, then jetison the battery back to earth via parachute. Retrim, and extend range greatly.
wouldn't extend the range. Adding ballast extends range. Look up the glider's polar curve at different wing loadings. In any case you need tail ballast to shift the CoG back to the right position if you fly without the batteries.
Simon Buckley i think it was Joke...
Couldn't find a price on their website. Does that mean it's too expensive?
Yup
It costs about 140.000€
If you have to ask you can’t afford it!
@@bridgefin Kind of.
Do you want to buy?
Beautiful glider. Pity it’s so loud... probably the propeller blades causing rupture in laminar flow around the nose area? I wonder if they can fix that. Thanks for sharing!
Yes, I also did not expect that it is so loud. But still better than the old sustainer engines. Thank you! 👍🏼
Is the era of commuting to and from a personal plane coming?
Unlikely. At least not with gliders.
Probably not too soon, but automated delivery drones for sure are.
It's always existed if you're qualified and have landing/takeoff room
@@PabloGonzalez-hv3td i'm waiting personal drone-like airplane, no need of large space for takeoff/landing
@@yuan.pingchen3056 It's a fantasy. The need for a safe t.o./landing area will never change so apart from aerial taxis using designated areas it's unrealistic for mass implementation.
I can't even fly my toy drone near people because it's legitimately unsafe.
Nice review Stefan, how do you have the time to create that many videos haha. This LS8 is a dream setup! - though would've loved to hear some range and performance specs on the FES system.
Thanks mate! Yes, it´s really time consuming to film and edit so many videos. Especially during competitions it is stressful. But now I´m back home and take some time to edit the footage. I had no time to make a proper range test only with the electrical motor. At one day I used 3,3 kWh and the battery was already fairly empty and the FCU said that I should reduce the power, even in level flight with 5 kW setting... So the reality is something between 60 - 80 km range in calm air. But most of the time this is enough.
If anyone is curious. Those 'screws' are commonly called zues clips/screws.
Commonly used for quick on and off panel applications in the automotive world as they only take half a turn or so.

Der Batteriegrösse nach , schätze ich , das 3Kwh elektrische Arbeit zur Verfügung stehen . Erstaunlich das 5kw Motorleistung genügen , den Segeler auf Höhe zu halten . Hab Dank für die Vorstellung des Elektrosegelers.
Angegeben sind 4,2 kWh, die aber nur bei geringer Leistungsentnahme realistisch sind.
@@SteFly Den Effeckt kenn ich von meiner Solarinselanlage . Das BMS im Segeler wird eine maximale Entladertiefe von 70% der Gesamtkapazität dulden . Wären AGM Batterien verbaut , dürfte man nur maximal 50% entladen . Bei hohen Entladeströmen hat man erhebliche Wärmeveruste . Mir fielen die 4 Kühlventilatoren im Akkuabteil des Flugzeuges auf . Also denn : Many happy landings.
@@arminmoller9927 An einem Flug hatte ich 3,3 kWh verbraucht und der Akku war schon relativ leer. Zeitweise bin ich aber auch mit voller Leistung geflogen, um einen Wendepunkt im Berg zu erreichen...
This is a fantastic glider. I have always wondered why we do not install solar cells as standard, onto these to increase range?
Finally they made a 1:1 scale RC motor glider ;)
What is needs is regenerative braking for when you get under a cumulonimbus cloud-- get a charge while limiting altitude gain.

Looks fun. Wish we mere mortals could fly too but it's pretty to watch also. Thanks for the vid and the plane looks and flies great from what I see here.
The Versailles treaty banned Germany from having an airforce after ww1. Germany formed hundreds of glider clubs and trained a generation of excellent pilots who could easily transition to powered aircraft when they built the luftwaffe.
All the buttons, screens and instruments and still one of the most important gliding instrument is a piece of wool taped to the canopy! Nice looking ship!
Why a piece of wool ?
Beautiful flying machines 👍
Wow that is amazing.. I love the future of aviation... thank you for this beautiful video..🤙🏻🤙🏻🤙🏻
future ?
Man, that folder looks CLEAN. I could see owning this...nooo problem. Would really like a self launcher, though, so that pretty up front prop isn't really the answer for me. Ridiculously nice panel, dude. Does the whistle diminish when you open/close the vent, or is that not a contributor?
That will simply be the future of gliding
"It's too noisy in here" well, it is but you can wear headsets for the noise. Nice glider
If you're flying a glider, you don't want to need noise canceling headsets. It's like heavy vibrations on a bicycle...
Hi Stefen , i absolutely like your channel , great job !
Very cool glider! How many minutes of power do those batteries provide, when on powered flight?
I wonder if a few earthX batteries could do the job for less weight? Battery tech really needs to move forward to make electrical propulsion a more viable situation than it is currently.
Who makes those jet sustaining gliders? I saw a new product a while back that uses electric driven wheels for take off augmented by jet propulsion for flight. Can't remember who is trying to develop it yet seems a very efficient use of energy as wheel traction is far better for take off and requires power for only a 15 second burn allowing the battery to be small. Thereafter once up to speed jet propulsion can prevail with optimum efficiency.
I also heard about a similar project, but with electrical motor also for flying. There are so many cool things to test :)
@@SteFly I will try to find it...and post it here.
@@PaulAnthonyDuttonUk Please do. I think it would be great to have a trolley that falls off the plane after the wheels power it forward.

Super Video! Mit vielen Infos, ganz toll!
bit disapointed thought the prop was going to get it off the ground
Yeah me too, I thought that was the point, not having to use a tow plane... So what is the point of it all?
@@gorway7 lift isnt easy to find. thats what its for.
me too
@@gorway7 i suppose if you are flying into a mountain you wind up the elastic band and hope that the prop gets you out of the way
"GLIDER"
I don’t like flying but not sure why I am watching this. Nice.
Please review the GP 15 SE JETA . From the stats it looks like it might be the best in class. Only you can tell us.
Unfortunately I had no chance to fly the GP 15 by now. But let´s hope for next year.
@2:10 is a mistake. There should be detents which prevent too much tightening and more importantly, prevent them from working loose. A small weight shift may be enough...
I saw this glider today @Bruchsal Airfield. I'm a proud member of the Lsv Bruchsal. :) nicely worked out video there
Add some ultra light solar cells on the wing to top off the charge mid flight and you could do some amazing cross country flights with security to cross the big bad sinks.
Hi Stefan, nice video again! :) was the noise in the cockpit produced by a bad sealing somewhere, or is it produced by the FES propellor?
Beautiful walkthrough 👌👍
This plane I literally have as an RC 😲🤩
Yes! Me too. I have a asw28 which is similar. The nearest i get to this is with fpv
Sensacional! Eu ainda vou ter um desses. Voar é simplesmente maravilhoso!
Lucky
I love how everything is perfect here
Besides the tow-hook, what else is sacrified for the FES engine compared to the normal LS8?
Can the rudder pedal go as far to the front, (the normal LS8 is not that big)?
Is is still possible to put trimmweights behind the rudderpedals?
At the prototype the rudder pedal looses one step, so it is about 3 cm shorter. But in the next gliders they will change it and the full length will be available. Trimmweight should be possible, at least I had some trimmweights in the trailer. ;)
You could use some packaging tape to temporarily seal one side of the time to see where the whistle is coming from.
Next add a solar panel charging system into the wings for the batteries?
That's not that simple. It's very difficult to glue PV cells to the wings, which are very flexible on gliders. Then there's a problem with surface, again, glider's wings are extremely smooth, and, of course, there's the weight issue. I think there's only one practical (usable) solar powered plane out there: Sunseeker Duo.
fifi23o5, the wings may not be practical without significant engineering, but I suspect they could put enough PV cells on the fuselage to trickle-charge the batteries while it was on the ground.
@@Vessekx such thing is already in use on gliders. Some have PV cells on the doors of retractable engine and it is used to charge the battery for instruments. Fuselage doesnt have the area to be sufficient for propulsion..
fifi23o5, I wasn’t proposing the solar cells would be used to driver he motor in flight, simply that it could be sufficient to recharge the batteries while parked, rather than having to disconnect them and haul them across an airfield.
@@Vessekx That wouldn't be very practical. You could get 150 W of power at most from the fuselage. And cells would have to be flexible and very small due to tight radius of the fuselage, so it would take an awfull long time to recharge the batteries. So, if I fly today, land late afternoon, when would batteries recharge? No flying for a day or two. Just not practical to be worth the effort.
Great honest review. Thank you.
Nice glider but the lack of t/o capability kills it for me. I'm extremely happy with my Silent 2 Electro which never needs a tow thus allowing me to fly out of my nearest airport whenever the conditions look right. It also allows me to extend my gliding season by about 2 months as all the clubs here are on grass fields which aren't usable until the snow is gone and the field is dry. It would be nice to have the extra performance of an 18m but only if I could take off.
@SassuWunnuOn Lak 17C-FES is an 18m self launcher. ua-cam.com/video/rxe6DIfPKb4/v-deo.html
I can't understan why someone will waste time or money in a electrical propulsion system unable to t/o
Since they installed an electric motor I thought they would demonstrate it taking off without the tow plane.
I think it’s a self sustainer , not a self launcher
how long can u fly with engine on? range if u can
Probabbly not really long.
Engine is used just to take off or gain altidute when needed.
I like the mauser cannon poking out through the spinner :-P
Brilliant design and very good glider
hmmmm
One variant of the Cri Cri is powered by two electric motors. It does not need a tow.

It looks like the batteries are either acid ones or AGM. Wouldn't it make more sense to use LiOn ones? They are more efficient and lighter. It's also a bit concerning that the terminal cables are not secured by anything to the batteries. It would make sense to use another bar on the top to secure them.
there Lifpo4 With BMS
Having to use a screwdriver to access the battery compartment is very impractical. Especially for emergency access to the battery compartment in case of fire. Perhaps an aviation snap latch might be better. Relatively light, requires no tools and flush with air stream.
Are you going to put the fire out? Insurance my friend.
DumbledoreMcCracken Are you the adjuster? Haha
In case of fire you are jumping out of the glider and hope your chute opens in time :)
@@randomnickify It can burn anywhere. Even while on the ground. Will still need screwdriver.
In case of fire, there's nothing in the battery compartment you want to access anyway. You can't put out Lithium batteries, just let them burn and have the insurance company get you a new plane.
Looks great. All it's missing is solar cells covering the wings and fuselage.
He said the battery was from 15-20 kilowatts, the wing doesn't have enough dimensions to justify solar cells (would take days to recharge them fully, and you don't leave a glider like that out in the sun).
@@freddyfourfingerz9126...you don't have to fully charge the batteries; it's extra power and range so why not?
compared to taxi drones, I think this engine looks more efficient.
but can't land and takeoff vertically.
maybe with more research, this machine will be future transportation.
I don't think that gliders will get commonly used aircrafts for transportation. It is awesome to fly them as a hobby pilot and they are very efficient.
Amazing glider stephan
What's the cost of owning the LS8-e in USD?$
Xman8184 well, it doesn’t have a motor, so it can’t be that expensive.
I've been looking online and the price ranges between $110k to $200k USD
since the prop folds, why not use a much larger slower turning propeller for efficiency? Why not solar panels on the wings?
Would be nice to take of from ground and not have to have a tow
Of course !
Look up the gliders with tow away jet engines
camtwan1 I like the idea of the folding prop, but the electric motor on a lid that folds out above the wing would be cool too, kinda like rc power gliders.
wonder if it would be worth covering the wings with solar panels to allow the glider to go farther if needed
I presume this requires an 8 ch radio?
Rudder, aileron, elevator, airbrakes, gear, water, release and throttle. So 8 channel should be fine ✌🏼😅
@@SteFly The pilot is quite articulated, though. That's at least four extra channels ;-)
