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.
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!
@@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 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.
@@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😭😭😭
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.
@@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
@@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.
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 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.
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.
@@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.
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.
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.
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.
@@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.
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.
@@ThisPartIsAndrew 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.
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.
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.
@@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!
How about keeping the jet inside the empennage and only open an intake NACA inlet when you want to use the jet? The outflow would be at the base of the tail at the very back. That would eliminate a lot of drag.
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 ?
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).

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.
@@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.
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
Tank You for thees videos,I like them very much,I'm 62 y old ,and that's remind me when I was 16 and I have flying 2 years with old romanian glider IS 28 and polish Blanik ín The socialist Romania.Thank You!
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.
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
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?
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!
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 was honestly wondering the same thing, small or not a jet engine produces a lot of heat. Maybe there is enough distance between the tail and the engine that it isn't a big deal?
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.
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...
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?
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.

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.
This is a must features for glider to avoid any incident
Like? I absolutely LOVE IT! How cool can it be?! Happy flying, and thank you for this great video! 👍
Appreciate your comment!
What about the heat from the jet exhaust on the tail? Is the tail protected from the impact of hot exhaust?
In my opinion there should be a temperature sensor on the tail where exaust gas hits the tail profile.
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'm waiting for the hot jet blast to burn off the tail, now that would be exciting.
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
Tank You for thees videos,I like them very much,I'm 62 y old ,and that's remind me when I was 16 and I have flying 2 years with old romanian glider IS 28 and polish Blanik ín The socialist Romania.Thank You!
I think the danger from the jet engine is that it could split the pilot's head in two from the smiling.
How's the tail holding up the exhaust heat?
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
Bro, you are truly an inspiration.
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 DON'T KNOW WHAT THIS IS BUT I SUBSCRIBED BECAUSE THAT FINISH WAS ACTUALLY INCREDIBLE
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?

CRAZY IDEA... R U GENIUS?
Just a quick question can you use the jet to self launch, without a tow plane?
ruclips.net/user/shortsuHuW3rib6-0?feature=share
I see you have the grips on the side to hand launch as well! That’s awesome!
Now you can say you flew in a private jet.
I'm waiting for the afterburner / reheat version.
This is a great idea. Especially if you need an extra boost to make it to your landing spot
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
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.
Для кого этот планер, для людей или только для финансовых грабителей рабочих?
Благодарю за уделённое время!
Желаю всем хорошей жизни!
Этот плане Российская разработка, и изготавливается в Перми серийно. Стоит приемлемо для ценителей.
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
Now I want to see a couple more popping out on the sides. Go full Jeremy in the skys, POWAHHHHH!
Really wish M+D could make this happen for the LS6 😢
What about the tail directly behind it? Won't it slowly start to burn?
I was honestly wondering the same thing, small or not a jet engine produces a lot of heat. Maybe there is enough distance between the tail and the engine that it isn't a big deal?
The jet is angled slightly away from the tail
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.
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.
WTF ? A jet propeled glider ?
Is there a Danger Zone button that brings the music too?
Can you smoke a cigarette up there?
Yes and no
Why in the fuck would you want to hot box that little space with a cigarette 🚬 either a super dope fiend or just disgusting lmao
Nice
Der Wunderschöne Jadebusen x) Von wo aus bist gestartet ? Hooksiel?
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.
Isn't it going to burn the tail directly behind it, this is such a great idea, this thing must get at least 100mpg
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?
