#LS4JET #JetGlider
I'm surprised they actually did this with a real glider.. I know it is common in RC gliders but a real one.. amazing
The engine looks like those on RC
Sonex make a kitplane that's powered by a dorsally mounted jet engine like this but it's $100k or so.
It’s not really common in hobbies unless you got money to burn
Okay
Dude where have you been? They been doing this for years.
Better view than an F-16 and jet sound to boot, awesome experience!
So true!

this is pretty trick 👌👌
@@SteFly ⚠️ God has said in the Quran: 🔵 { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 ) 🔴 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) 🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠️ Quran
I've always wondered why they never designed a dual mini jet system on a glider It seems like it would be a blast I really consider trading my bike addiction for flying
problem is weight mate, this had 19l of fuel, and im guessing youd get what 10 mins out of that if that, two even light jets youd need double the fuel.
yooo same here a dude i used to ride with on the canyons got his pilots license and i keep seeing the snaps of him flying like wow i'm over this bike LOL
Flying is great man, definitely get into it. I traded my bike and coke addiction for flying. I’m a commercial pilot now but I still got the coke habit lol.
@@ColAlbSmi please open your big book to p.522 xD
The closest to a flying bike would be hang gliding. I was addicted to cycling for 5y before I started HG and never looked back!
The suprising element of this setup is when you are a resident of the area where this video was taken: you hear a jet engine and you are looking for a jet and only see a soaring glider buzzing around :-) As M&D Flugzeugbau is around the corner this a regular event but always cool to watch.
People are asking about the heat of the exhaust on the tail section, but I wonder what happens when that hot engine is retracted back into the tail boom? Great ideas include huge challenges. I love the idea!
It's not super difficult to insulate against some heat, but probably best to leave it extended to cool down first
From what I read the unit won't allow retraction until the EGT reads 50C.
You would leave it out for a few minutes to cool down before retracting it.
@@jamesogle99 Huh so that's why it's not manually extended. Would've been a total no-brainer but that can result in an unwary pilot setting his glider on fire.
I talked to someone from M&D at their booth in Freudenstadt last year and apparently the thermal mass of the turbine is low enough to cool down within less than a minute. Drag is about the same as leaving your gear down
this is the ultimate flying experience. the purity/thrill of a glider, coupled with the convenience of powered flight, at a tiny fraction of the cost. it kills more than a few cats with one stone. love it!
That clip of the jet engine, sliding out of the fuselage at the first couple seconds was glorious
I like the idea of twin engines, angled so they don't roast the tail section. Be ALLL the power that glider would ever need.
Good to see this approach of vlog, commenting and explaining as you go. Well done and keep going with this inspirational path.
Thank you!!
This is why I love your channel. Practicality and a little fun at the same time. The fuel flow is pretty high but as you said… use it as a sustainer and then when you get back to the field, if there’s some fuel left over, let her rip!! A little fun at the end of a long day in the saddle is what dreams are made of. To me it’s worth the money just for the fun factor!! Awesome video.
Thank you so much!

@@SteFly i curse myself. Many people made own helicopter and planes here but government arrested them and put them in jail for innovation. Also confiscated their flying vehicles too😭😭😭
@@Kite-xp2lz thats a good thing. Imagine selfmade planes on the sky ☠️
Adding propulsion with a light weight high torque retractable turbine is genius to give possibilities of sport glider usage!!...Well done fellas!!
The first time I have seen this. I was always wandering when someone was going to do it. I love it! Thanks for sharing. Amazing!
The pure joy on your face when flying it that’s so awesome you got to fly this beauty!
That is so FREAKING COOL !!!! I want one !!! That is a great setup ........ it will give you enough power to get you back home, to keep you from having a "out landing" when there is no wind.
“ an” out landing.
You still need towing plane to take off. Sad.
@@user-sv3ug5js5s You can be winch launched, it just depends on the airfield you launch from.
From 3:26 to 3:55 the best timeline of the video, including your excitement that was captured well! I wish I could try this too
That’s honestly so cool, it can be small because glides have a lot of lift. And it looks so cool coming out. Awesome idea😊
At first I wondered how close the hot exhaust of that jet was to the tail of your glider! 🔥
same!
It will be a problem over time. It would of been better if they used 2 jet engines 🛩️
Yes seems like it will cause stress cracks over time.
@@Funk_Reactions Something to keep in mind: as the aircraft is traveling forward the EGT (Exhause has temperature) mixes with outside air and the temperature lowers as the air molecules mix. By the time the exhaust and outside air reach the tail section its probably not much warmer than a medium hair dryer or lower. I would agree if you tried to use the jet engine for take off, yes, you'd literally burn the tail off the glider.
The tail must have to made out out aluminum somehow to resist the heat, I think. Once the plane is flying through the sky, it will be sufficiently cooled by the passing airflow.
Biggest risk is uncontained fire from the jet engine, also there is no aluminium shielding on the rudder leading edge. Overall , Very cool design and excellent power weight ratio
Fibreglass too, aren't they? Fibreglass fires on water are a nightmare. Can't imagine one at 10k ft with control cables running through there. Give me a parachute.
@captainotto my club doesn't allow anyone to step into a glider without a chute
@@znek4288I could imagine, I wouldn’t want someone dying on my watch neither. Insurance would be screwing your hard if that happened lol gotta have your ass covered lol
Yes, I wondered about poss heat damage from exhaust. Also, I'd imagine the engine must cool before it is stowed to avoid internal fire.
@@bartofilms Those engines do need to cool before stowage. In fact, you can't even shut them off without keeping airflow over them or their bearings will fail by heatsoak much like your typical automotive turbocharger would.
Thanks for that ride bro, amazing, this plane shows safe to fly.
Sehr cool! Schöner Start mit Blick über Wilhelmshaven!
The engine is really cool to put on this glider, amazing design
Saw this retrofitted onto a glider several years ago and it seemed like a good idea. It's a great way to get out of trouble with a glider if you need extra time to find a place to put it down. Great idea!
I didn't know something like this existed, absolutely love it, it opens up so many more possibilities for gliding while perhaps offering some reassurance as well as making it easier to maintain flight time if the air isn't cooperating.
Stef, that smile is priceless!!!
Holding a selfie stick camera out the tiny window. Amazingly cool.
That's not cool, that is stupid.
@@fredf3917Just like you
This is kind of a total antithesis to glider flight and I fucking love it. Top gun. Jet. Thrust. Yess. Lezzgo.
One of the most epic uses of these Rc Jet engines EVER!!!
Bro, you are truly an inspiration.
I was really waiting for a high speed low pass with afterburner 😈😎 But nice vid, the owner must be super happy with the glider 🙂
LBA is watching 🤣
@@SteFly that's what I suspected 😆
Afterburner..? 😆 🤣 😂 Yeah, ok. 👌
"Afterburner ON... wait, where did the tail go?"
kzhead.infouHuW3rib6-0?feature=share
The ability to abort landings or touch and go for gliders cannot be overstated. I understand cost prohibits every glider from having an auxiliary engine, but after seeing this I don’t think I’d fly one without it.
It's not just cost. Adding an engine lowers the performance of the glider and drastically alters the weight and balance.
Overstated.
@@kiereluurs1243 Thanks. I was looking for a free proofreader.
Like? I absolutely LOVE IT! How cool can it be?! Happy flying, and thank you for this great video! 👍
Appreciate your comment!
That is amazing. That makes gliders totally reliable for long distance travelling. Amazing.
Great review as usual Stefan
Sonho de consumo!! Gostaria muito de ter um desses no Brasil
8:10 Now that's a money shot! I've suddenly become intrigued by Gliders.
Hahaaa, cool!
Amazing the power a small jet can create
This is one of the most amazing things I’ve ever seen! 🎉
Glider-Jet is like... printed e-book 🙂
The ability to climb 2500 m using only 20 L of diesel is absolutely phenomenal. I can see this being used in the intelligence and surveying industries. You could also hop from thermal to thermal easily.
Jets do not use diesel 😳
@@benturp3492 This one does.
@@benturp3492 did your teacher also get frustrated with your comprehension skills
@@FarmerDrew I wasn't beeing taught proper English. Like you Americans can talk :)
@@benturp3492 Americans don’t speak proper English
Das ist ja richtig verrückt! Happy landings! :-)
Hey Stefan, about 50 seconds after you said that you felt like a Top Gun pilot, an add for Top Gun Maverick popped up in the screen! Nice video and the jet sustainer looks awesome!
Hahaha, in this case the ads algorithm works great :D
Dedication with the camera out the window for the money shot of the Jet. Thanks. Looks like an awesome way to make a glider even more fun AND is a bit of an insurance policy against having to land in a random field.
What's really crazy is that small of a Jet engine and produce enough power to keep a glider in the Air efficiently.
You should check out the SubSonex :P Keeping a glider in the air doesn't need that much anyway.
i thought this was a digital video game at first it was so perfect; too perfect
amazing experience, probably gonna buy this one in few years
This is a great idea. Especially if you need an extra boost to make it to your landing spot
Jets make perfect sense. Great power-to-weight ratio. And you can run it on anything...
No you can't......
@@benturp3492 Yes, jets run on a ton of different fuels.
@@of_the_stone I am an aircraft engineer mate and I can tell you that they don't. Avgas, A-1, Jet-B and there's bio kerosene too. They cannot just run on anything!
@@benturp3492 👏🏅🏆 ok, you win. 🤦🏼♂️
@@of_the_stone you clearly have no idea what your on about mate. 👍 Good thing your not filling up planes with any kind of fuel that takes your fancy!
That s amazing, great solution for emergency too
Now I want to see a couple more popping out on the sides. Go full Jeremy in the skys, POWAHHHHH!
Would love to see more of this. I would think that once the motor is in full burn that the exhaust in only water as efficiency is very high.
kzhead.infouHuW3rib6-0?feature=share
The fuel has carbon in it, therefore the exhaust does too.
@@SnakebitSTI Not if you have a good burn going. There will be only water. You may have 20-50 ppm CO. Miniscule.
@@grabir01 It's a jet engine, not a nuclear fusion reactor. Carbon in -> carbon out. Hydrocarbons in the fuel get broken apart and oxidized in the engine. An efficient burn means the hydrocarbons are mostly converted to H2O and CO2. In practice, there will always be particulates from incomplete combustion and other pollutants like NOx and SOx compounds. To produce pure water exhaust, or close to it, you need to use pure hydrogen as the fuel and pure oxygen (not air) as the oxidizer.
@@SnakebitSTI I posted the carbon out measurement real time. IT is not zero. It is super low for sure. A very very efficient burn for sure.
I love the evolution here: weight to available thrust being the operative point! I'm a bit cautious as the jet blast is extremely hot and thinking the integrity of the vertical stab' is a question?? I'd love to get your perspective on the climb rate with the jet? That's the real value here, in my opinion. Of course you can jet cross country but what is the climbing (VSI) capability? Fuel duration isn't such a big deal if you can grab crazy altitude!! Great flight and vid' as always Stefan. :)
Thank you! As mentioned in the video, the climbrate with a IAS of 135 kph is about 2.1 m/s. With 20l of Diesel fuel you should be able to gain 2500m of altitude.
The jet is mounted ~2° sideways So the hot center of the jetwash does not even touch the vertikal stabilizer
@@glucksi1655 At the LS4 it is mounted straight, but they needed to measure the temperature on many points on the fuselage to certify the glider. Of course they also tested at high outside temperatures.
@@glucksi1655 Or maybe underneath since it retracts?
Or maybe underneath since it retracts?
This is a great Idea chum, Spot on.
Very interesting, have not flown in a while, but this looks like so much fun!
Incredible! I would be completely paranoid I'd damage the vertical stabilizer the whole flight if I were me.
1903 - 1969. 66 years from the first 103 foot flight to landing Armstrong on the Moon. People who watched Apollo 11 remembered reading about the Wright Bros flight in the paper. Amazing.
I wonder what kind of maximum distance you can actually get with this setup.
THAT'S SICK!! I LOVE IT
Das ist ja absolut krass!!!! Ich wusste bislang nicht dass es so etwas gibt. Es sollte nur technisch ausgeschlossen sein, dass die Turbine im eingezogenen Zustand zündet. Sonst wird es warm im Flieger 😉. Vielen Dank fürs Zeigen.
Since the question is raised many times now, I would like to mention that on the JS, the turbine is placed at small angle so the exhaust gas will fly past the tail rather than head on. M&D probably does the same for the retrofits. It just requires a bit of compensation with rudder when flying. What also should be mentioned that the system is really loud. It works great but mind the neighbours, not everyone is a top-gun fan.
do you need a licence to use this glider ? i mean...the question seems important to me. thanks
At the LS4 the jet is not installed in an angle because the short fuselage would cause a strange flying behavior. Of course the needed to measure the temperatures in extreme environmental conditions for the certification process. So everything is fine on this side. That´s true, the outside noise level is high and you should take care with noise sensitive neighbours.
@@pakkiaman2 Yes you need a glider licence but nothing special for the jet.
Or maybe underneath since it retracts?
It looks great! Any protective precautions applied to your tail to protect from jet propulsion heat?
Doesnt look like it. Long term effects are likely not taken into account. I cant find any aircraft where a jet turbine is point directly at a flight surface
I've always liked gliding but this really makes me want to try it one day
Wow, I see a new design of this modified glider hitting the market lol wow. I want one now lol great video 🤙
What about the heat from the jet exhaust on the tail? Is the tail protected from the impact of hot exhaust?
Really wish M+D could make this happen for the LS6 😢
Holy shit I can't express how cool this is. The way that mini jet deploys and THE SOUND, absolutely insane
This is bloody awesome.
With 40 Liters of fuel up to 200km range is not bad. 100km at max power
There is an option for 60l fuel tank in the wings available aswell. Overkill imho :D
Nice! But can it take off on its own power?
Really cool sound! 😊
That's as cool af. Absolutely freakin sick tech!
This is an awesome option to consider! Any idea how long from power-on until climbing away from your landout? How much weight does the system and full fuel add to the empty weight? Do they have any information available?
I have seen somewhere on their page that it takes 40 second to extend the jet and power it up to 30.000 RPM. Then it will take some more seconds to get the full RPM (95.000). So 50 - 60 seconds until the full power is available.
I think the danger from the jet engine is that it could split the pilot's head in two from the smiling.
This is a must features for glider to avoid any incident
Great Idea, congratulatios.🇧🇷🇧🇷🇧🇷
The Jet turbine is Amazing adaptation to the Glider hope the reliability is as good as small petrol or electric propulsion units ... I wonder if self launch could be possible ?
Most likely it's possible on a long runway but not certified for it ;) I have seen a video of a JS3 with this jet making a selflaunch.
Yes, "amazing" consumption - 65l. Especially these years. Take off generetates probably some risk that tail will burn - no cooling (no air flow at the first phase).
@@SteFly decades ago, diamant 18 with a microturbo éclair out of Altenrhein am Bodensee, registration HB-2020 . Easy take off, Fixed installation, no noticeable effect on sink rate, in a thermal could not notice it's presence. EFF made the modification.
@@podunkman2709 No problem: mixing cools the jet rapidly, soot deposit is small but visible.
Joe, 1 moving part is as reliable as it gets, once the electric starter gets it to ignition rpm. Electronic fuel control, simple compared with the one used on much larger engines. (FADEC)🇧🇴
Maybe I missed that part, but for me a major point for any kind of propulsion on a glider would be the question if it offers you the capability of taking off on your own? Here someone had to pull you up with traditional motor plane, which creates a massive dependency on others and equipment as well as extra costs, but is this tiny jet really to weak to accelerate you on a "normal" length runway to a speed way beyond safe lift-off? I guess the roll resistance is so high that this jet is in the category of a more sophisticated hair-dryer ? 🙂
With enough runway it probably could, but if you want a powered glider then there are purposefully built ones. Gliders sacrifice all for performance in the air, including the self launch capabilities, that's why it's a sport. Win some, lose some. If you want it back, you'll have to sacrifice performance and you get closer to a regular aircraft. The point of this kits is to increase flight time and add capabilities while keeping added weight and drag to a minimum.
@@moteroargentino7944 I have seen gliders with props on an electric motor that, just like this one, completely disappear into the fuselage, so they are aerodynamically no sacrifice, they are just like having a passenger behind you, some extra weight. And they have the ability to actually get in the air by themselves. So you think the extra weight is such a big sacrifice? This jet is obviously a very compact add-on that is strong enough to keep you in the air for quite a while, once you are up there. Maybe it also comes in handy if for whatever reason you end up above the clouds and you are looking for a safe hole to get back underneath again. I am not a glider pilot, but as a motor pilot this can easiely happen and then you are much more safe if you have enough fuel and can stay up there and find the right spot to descend, avoiding IMC.
Exactly!!!
kzhead.infouHuW3rib6-0?feature=share
You would burn the 20 litres of fuel just trying to take off lol
Looks like alot of fun!
Hey, just back from Namibia and wet season just started so good, unstable systems now…like last you when you were there….💪✈️
Does the exhaust gas damage the tailplane or deposit anything on it?
No, it doesn't damage the tailplane but you should clean it after use of the jet.
I have a question; the heat from the thrust hitting the tail, wouldn't that cause a problem later on?
The engine is in a slight angle
Seen this in a flying display at Avalon airshow in Victoria Australia today, pretty cool.
Dieses Uhh bei 0:05 🤣🤣. Aber wieder ein mega Video 👌🏻🛩️
Does it work well? How much thrust does this jet engine produce? It looks a bit small for the size of the glider🤔
just dont do pougachev cobra or immelman with that things🤣
It's good enough to maintain speed for about 10min. This should be a requirement for gliders. If you need to stay in the air longer to get to a safe landing, the jet can be a life saver
I’m pretty sure the engine makes 420 newtons of thrust at max
I am in no way shape or form a pilot, engineer or mechanic, with that said does that jet engine not generate (in full throttle) enough heat to damage the tail section?
La Tierra es Plana!!!! Magnífico!!
I see you have the grips on the side to hand launch as well! That’s awesome!
Amazing. Gliders should have (as an optional feature) a possibility of installing a jet engine. What is the thrust level of this particular engine?
Maximum of 350 Newtons ( 35kg) of thrust at 1.3 litres per minute.
There are gliders that use an electric propeller with folding blades to do more or less what this offers. I'm thinking that the jet is probably more weight efficient though run time is less.
@Michal, that information just 'can't' be found. It's not like we're on the "Internet" thingy that we've all heard about.
@@fredflintstone8569 thanks
Just a quick question can you use the jet to self launch, without a tow plane?
kzhead.infouHuW3rib6-0?feature=share
Wie genial .. da hat man lust mit zu fliegen
He makes it look so easy
Super! Can you also take off on jet power only?
No way, there's too much surface friction
Maybe with a very long runway and some drop tanks. Slowly accelerate, take off, gain altitude, drop the tank(s) safely over the airfield to lower weight and drag, then perhaps it would be viable. A piston-prop setup would be far superior for a glider.
@@d00der41 I have seen videos of one taking off with jet power alone
@@FarmerDrew Yes, but at many places there isn't much fuel left after takeoff and climb to travel to ridges and thermals. These jet gliders don't have much distance after taking off, which is why he took off in tow. Hence why a piston-prop setup is an ideal powerplant for gilders.
Anyone else wish we would heard the engine go into reverse thrust on landing?!?!
Just flip the complete jet over so that it makes reverse :D
@@SteFly also can be used as hair dryer for pilot when the cockpit is open
I would've mounted it to the side just above the wings so the exhaust doesn't melt the tail (the torque effects wouldn't be that bad from such a small engine) or used 2 so I could have 1 on each side for even thrust
That Jet start up sound is music to ears
This is so awesome!! Can you use your jet-engine to take off? thank you for sharing this video!
Good question
The published climb rate is 360 feet/min, that's too small a margin for my taste.
The awesomeness of hand outside the window with selfie stick cannot be understated. Could this also be a Twinjet? Stacked on top each other? Hard points for weapons and fuel tanks? Zelensky would like to know...
all he need is a pistol with one bullet inside, that's enough.
Das klingt Gut 🔥
Fun-tastic, I like it I guess I have to come to Germany to enjoy😊
Hi Stefan, I have 2 questions: 1) Can it take off using the jet? 2) After shutting down the engine , can you retract it to the body or is it too hot and needs to cool down?
Esfriar né
I saw this years ago by Eastern European company that had a glider with a jet. Now it is available that is amazing. I'm getting a glider.
That is totally wicked!!
Good video...what a sensation...love it
