I'm WAY excited for this. This puts SCOUT in great position with the Icarus Challenge. You pump gas and get amazing range. I come from dirt bike culture and fly paramotors now. When Yamaha led out with the YZF426 and won with it the rest was history. That linear power, cleaner burn, and fuel economy matched with great power is fantastic!
I'm a rider, too, who is also knocking around this as my next sport. Plus, how cool to travel with it and fly all over the US. Nonetheless, SCOUT is the best by far. Safety, anti--torgue. Now a 4S? Nice! That's the one I'll buy. Like you, I believe in 4S. Maybe Yamaha, or Honda or Kawi should build these. If they did, you know they'd be fast and last. PERIOD! I want a Hayabusa PPG!
Terry at Falcon 4stroke here..good work on the project, do not be detracted by downer comments. Do not try to incorporate every suggestion from would-be buyers. Return-to-LZ reliability, heat control & manageable weight are the most important features, everything else is a bonus. EFI is fine but will not produce more power than a well tuned carb. EFI is reliable but when issues arise it will be frustrating and expensive to owners. I would prefer to see the familiar Walbro pumper matched to the motor. Baily's 4stroke entry to the US market was a disaster and spoiled the 4 stroke foot-launch trend for years. Study this and don't repeat:) I more thought..this is a process, maybe better to not share all prototype problems. This candor will be used against you by other marketers in the future. Quietly solve the problems and support the engine once it's introduced officially. Be truthful always with your buyers and you will do well.
Yes you are right. Carb at the beginning for sure... We do not mind sharing our path to make the engine market-ready. Roland from EOS agreed to play a fair and honest game and all the issues must be solved before selling to customers. We do not mind them knowing how much trouble it takes to tune an engine...
While it may not produce more power, this does have advantages in that the carb does not have to be manually adjusted when changing site elevation by doing it automatically. This will save maintenance and wear on the engine by avoiding running lean or rich and ruining the piston or wasting fuel operating in a choked condition in higher altitudes. Efi is not rocket science to troubleshoot and if readily available automobile or motorcycle components can be incorporated, this would greatly reduce costs by avoiding the use of 'special parts' exclusive to paramotors. As a first engine, i would certainly consider s small added premium that would become neglibile over time.
'Bailey' in the UK have been producing 4-stroke engine paramotors here in the UK for nearly twenty years, they even use the same GY6 Honda engine as a base, the one Scout has used here (re-engineered crank case). I even made my own machine based on this engine about eight years ago (check out my video's). Good engine, bit heavy though!
This looks really good. Of all claims though, I want to see the engine on a scale. 15 kgs all up weight for a 240cc 4 stroke is VERY light, this kind of figure is rarely achieved by 2-strokes of similar displacement.
Awsome!! I love the Scout gear. Four stroke is the way for sure , I fly a F.B. Trike now with the four stroke Swiss Auto and love the sense of security over the two stroke. I wish I were younger because I would love to fly the back packs again so I could fly a Scout. Any way, keep building premium stuff Scout. (:
So it’s been almost 2yrs since this post and SCOUT Paramotors isn’t currently offering a 4 stroke engine. Were your predictions of it being the best Paramotor engine a bit off? I like the idea of the 4 strokes as well, but only Blackhawk seems to be selling them, at least from what I’m seeing so far. Any updates on this engine?
1/2 the fuel burn ?? It’s impossible 20-25% less is more realistic . If the specific fuel consumption where so good on this engine , nobody els in the world would produce a engine anymore !
Bailey unfortunately does not come anywhere close to the power nor weight of the two stroke engines. This is why I don't consider it to be true alternative
Im excited! I would be more excited for EFI though. KTM is releasing a EFI 2 stroke this year which is awesome! The performance as well as range gains from a 2 stroke EFI engine would be monumental. Especially with how the sports environment changes so dramatically just in 1 flight. EFI would change the game. An actual developed and reliable EFI 2 stroke engine (not a EFI kit) in the industry would be unparalleled. I think we are about to see a lot of innovation come down the pipe line in coming years.
so 7 months later , do you have any updates yet ? I'm considering to get some PPG training next year and would really appreciate 4 stroke engine after my graduation , i don't like the noise of 2 strokes.
+TerraBiker I very much hope we only need one more week... One more week for some relevant updates... Still far from serial production. Do not postpone this sport! Get a 2stroke and have fun. Upgrade later!
In this age of electronic ignition - EFI would be even less trouble than a carb with it's tuning even with the minor power loss associated with FI. How many 2-strokes in the field are properly tuned anyway? Good luck, Sir.
Yes, it is time to move away from the carburetors. This is the 21 century. All cars have them so why not the paramotor? What about electric start added to this 4 stroke engine?
Scout Paramotor : I believe somewhere you said people can get into this sport now with one of the existing engines, and upgrade to the 4-stroke engine later. Since I'm not familiar with this sport yet... but just got totally jazzed by watching your 30 geometry + other videos... I have no idea how modular these paramotors are (your brand or others). Please explain what will likely be involved in upgrading to the 4-stroke engine... including which parts will need to be replaced (in addition to the engine of course). And please also just say a few words about how modular and "mix-and-match" these paramotor products are. Though I have no experience with paramotors yet, I have been a private pilot for many years... not that I expect that to make the learning process that much easier. This is probably not the place to ask, but let me also ask whether what I would want to do with my paramotor is actually practical or not. I will describe my tentative plans here: #1: I may fly here in modest altitude places for a while (4000 to 11000 feet), but the application I really need one of these paramotors for is to explore extremely remote locations in the Adacama Andes in northern Chile. Thought this area extends all the way to the pacific ocean (0 foot altitude), the lowest altitude passes between many of the andes mountains in this area range from 15000 to 18000 feet, with mountain tops from 15000 to 26000 feet. While I don't expect to climb as high as the highest peak (over 26000 feet), I would like to be able to explore many peaks in the 15000 to 23000 foot range if feasible. Yes, obviously I'll have to carry a small oxygen bottle and breathing mask.... just as I would in the small single-engine airplane that I'm planning to buy (pipistrel virus sw with 912iS engine). One guy flew one of these airplanes over the top of Mount Everest, the crazy SOB, while on a solo flying trip around the world! The reason this airplane isn't sufficient for all my needs is... I won't be able to land any regular airplane on/near the top/rim of any/many of these mountains/volcanoes, whereas obviously not much room is needed to land and stop one of these paramotors. #2: I would want to fly for as many hours as possible each trip (and the greatest distance possible too). Typically zero human beings live or work within tens to hundreds of miles of these peaks, so the logistics get vastly less hassle the further each flight can last. #3: If one was to run out of fuel near the top of one of these mountains (say 20,000 feet for talking purposes), how far can one glide for every 1000 feet of lost altitude? In other words, what is the glide ratio for a heavily loaded craft (but zero fuel remaining) at high altitudes (15000 ~ 20000 feet). The idea is... if one can glide far enough, one could plan longer excursions by planning trips that consume all fuel (followed by gliding back to the starting points at lower altitudes (typically 10,000 to 15,000 feet). #4: What kind of paramotor would you configure for such a purpose? That is, assuming there is such a thing. #5: What considerations need I consider? #6: Yes, I'm insane... but I lived and worked at high altitude observatories for many years of my life. So I'm a bit less insane than you imagine. Thanks in advance for the information!

Very interested, hope it won't take too long before we see it on the market, this is what we want in ppg. Bailey V5 sure great stuff, but heavier, and less power. Great to see Eos working on this. I start to save right away, definitely something I would buy. But, I really hope they take a look into fuel injection if there is anything they can optimize for ppg. That would be a game changer if it came in a nice package.
The project is still alive. We did one update video last year. Current status: Exhaust problems solved Lubrication problems seem to be fine but needs more testing Engine increased from 240 to 290cc New cylinder head with 4 valves instead of 2 Now facing some issues with cooling 3 prototypes being build now in the eos factory in austria. Hope to have the motor back for testing soon.
Looks like the EOS Quattro 4 stroke is alive and looking to be released soon. Are you guys involved in the testing? Any plans to add this as an optional engine on future Scout purchases?
Big question over current two strokes: Does it run on 92 octane automobile pump gas? Our premium is ethanol free but many places aren't, will this motor be ok on ethanol blended fuels?
Do me a favour - if I'm not mistaken this is a GY6 157 QMJ based engine - probably the commonest 4 stroke scooter motor on the planet made by dozens of China based manufacturers turning out clones of the original Honda engine it's based on. 18 to 20.5hp depending on what overbore kit you go for. Paul Bailey in the UK did it years ago with 5 versions. Looks like another CNC crankcase and overbore to me!
Is it possible to supercharger one of these engines to help at high altitude? I know back in the dat the P51 Mustang supercharged it's Merlin engine and that boosted performance dramatically.
Don't think that you should have the intake next to exhaust minor change could put the carburator facing up to get fresh air. Its getting heated air and also less oxygen..! Lots less noise too with better fuel mileage with the new motor. I was wondering when it was coming out, probable price could be cheaper too! Don't have to wind it out launching it!
Please make an update video with insights from your testing...you said that you intend to put 100 hours on this motor within two months...and that was 3 months ago. This 4 stroke game changer is such an interesting topic. Please give us an update even if there isn't anything new to share we still want to know what's happening.
Have you tried Bailey Aviation 4-stroke? It is there on the market for ages. Same story: linear, fuel-efficient, quiet, etc. The paramotor update of some classic Honda in fact.
Really interested. I like 4-strokes, but Bailey is a bit underpowered for me. Is it possible to compare the tech data? (There is nothing yet on EOS site). Also: is it injector or still carb? I am very looking forward the injector motors, since I believe it has to improve start and run (the way it did in cars industry). Thanks you!
I have been a PAP man for 4 paramotors (PA125, F200, Moster and now Thor250) in a row but this 4-stroke would be my ticket to change the frame too! Where do I send the money? ;)
Wirmish, if you redirected the exhaust to the rear then the exhaust would go through the prop area, perhaps that’s not a good idea. I really don’t know. It sounds like it might not be a good idea.
Yup, looks like GY6 Scooter yet again, but I don't see fan cooling for the oil. Maybe more oil than a Bailey, but essentially looks the same. Same exhaust issues too. Donor Engine costs a few Hundred dollars. Nice $$$.
Sir what do you think about fresh breeze is that a good motor I'm new to this sport and would like to get gear for normal country cruising not a lot of maneuver
While I would sometimes choose design options I respect other manufacturers. I am sorry but I cannot give advice which paramotor is good or bad. My goal is to share my reasoning and teach you how to make your qualified judgment what is the paramotor for you: ua-cam.com/video/EfNU9v1FyEs/v-deo.html Today we start shooting another set of videos about frame geometry. Small details that most pilots never thought about but yet they are so important...
So I'm guessing the issue of engine outs is greatly reduced with the 4 stroke? Btw, will this come with an e-start? And are we looking at 6-12 months roughly before this thing is ready to be released, or do you think it'll be 12+ months?
I'd be curious to see how this stacks up against the Nitro Tornado that was recently announced. If I can fly with a 4-stroke I will over a 2-stroke any day. However, I'm a big guy and I need a lot of thrust. I was even playing around with the idea of figuring out how to get the tornado mounted on the scout if possible. LOL
That's seems to be a good engine, for now though I will stick to my trusty 185 monster with over 500 hrs. on it with out a rebuild. Good luck with it, might be the real deal.
have the used a crank weight to help with the idle? did they balance the crank to prevent vibration? also is anyone considering e start? best of luck im watching the progress have a great day
No two stoke oil, lower fuel burn, flat powerband, lower noise, lower rpm, clutch, ....wow should I go on? If the power is truly comparable as is the weight this is a no brainer. Longevity is the key, I would imagine it has a 12:1 compression ratio to compete with two stroke power which would lower reliability somewhat but a two stroke already has a short life because it works twice as hard to do the same thing. I am excited to see this.
We participated on this project years ago as testers. Everything I said in the video was true but the engine had reliability issues and we came to a conclusion t was not ready for the testing phase yet. We stepped out of the project few years ago. The manufacturer (EOS Austria) continued the development and now they are releasing the engine to the market. I hope they succeeded to fix the issues. I will want to get one for sure. But right now I want to finish our own ongoing research and development projects before I get my hands on this one. Go get it and tell me:-)
that was 3 weeks ago. I've got a wad of money waiting to be spent on that engine. if its more than about a month i will be forced to buy something different. when can we get it? PLEASE!
how about increasing the compression, but adding a flywheel weight for good balance and helping keep a consistent idle. i would rather not sacrifice power. titanium exhaust would help too. as far as engine internals usually a forged connecting rod, crank ,and piston and good size bearings stainless valves are tough too cheers
Just saw the update video! Looks promising. I hope it all works out. It sounds like you are wanting to implement something similar to an oil catch can :) www.ctsturbo.com/cart/products/CTS_Turbo_MK7_Golf_R_8V_S3_Catch_Can_Kit-4863-581.html
+General Disaster sure we had. I was even considering that for myself. The weight would not be a big issue but it had little power. I have been waiting for a powerful 4 stroke for long...
+David Vermillion there are a few experiments with fuel injection on two strokes but none of them made it to serial production... At least what I know.
+Sabaoon Sangar flown it today (again). Just quick update: new carb, new oil routes, new exhaust with 27 hours without breaking... We have some footage to share but we will not be able to edit for two weeks (vacation). Overall good news
Is this still in development ? I would love to see a 4 stroke alternative succeed.
Update?
March 31st 2017 - "I'll keep you updated". Jan 2018 - Any updates?
Wow! Rock on Miro, what a great project. If this turns out to be as good as you hope, it'll change the entire industry for the better. I'm excited!
Hey eric, love seeing all the paramotor dudes around the comment section, such a tight community
It's been a year... Has it?
I'm WAY excited for this. This puts SCOUT in great position with the Icarus Challenge. You pump gas and get amazing range. I come from dirt bike culture and fly paramotors now. When Yamaha led out with the YZF426 and won with it the rest was history. That linear power, cleaner burn, and fuel economy matched with great power is fantastic!
yes this would be the ultimate Icarus paramotor....but it must be reliable and time is needed to prove it.
Hopefully it's reliable like the old Honda XR motor. And hopefully they use a good titanium valve so they don't stretch out.
Single piece forge- not the bonded.
I'm a rider, too, who is also knocking around this as my next sport. Plus, how cool to travel with it and fly all over the US. Nonetheless, SCOUT is the best by far. Safety, anti--torgue. Now a 4S? Nice! That's the one I'll buy. Like you, I believe in 4S. Maybe Yamaha, or Honda or Kawi should build these. If they did, you know they'd be fast and last. PERIOD! I want a Hayabusa PPG!
SCOUT paramotor any tangible updates on the 4 stroke Miro?
Terry at Falcon 4stroke here..good work on the project, do not be detracted by downer comments. Do not try to incorporate every suggestion from would-be buyers. Return-to-LZ reliability, heat control & manageable weight are the most important features, everything else is a bonus. EFI is fine but will not produce more power than a well tuned carb. EFI is reliable but when issues arise it will be frustrating and expensive to owners. I would prefer to see the familiar Walbro pumper matched to the motor. Baily's 4stroke entry to the US market was a disaster and spoiled the 4 stroke foot-launch trend for years. Study this and don't repeat:)
I more thought..this is a process, maybe better to not share all prototype problems. This candor will be used against you by other marketers in the future. Quietly solve the problems and support the engine once it's introduced officially. Be truthful always with your buyers and you will do well.
Yes you are right. Carb at the beginning for sure...
We do not mind sharing our path to make the engine market-ready. Roland from EOS agreed to play a fair and honest game and all the issues must be solved before selling to customers. We do not mind them knowing how much trouble it takes to tune an engine...
I greatly appreciate the honesty in your process. I am not motorized yet, but am likely to go with Team Scout when I become motorized.
SCOUT paramotor This is the kind of comment that makes me twice as likely to buy a SCOUT.
Don’t agree re letting people know the development process. I think it adds to the overall trust.
While it may not produce more power, this does have advantages in that the carb does not have to be manually adjusted when changing site elevation by doing it automatically. This will save maintenance and wear on the engine by avoiding running lean or rich and ruining the piston or wasting fuel operating in a choked condition in higher altitudes. Efi is not rocket science to troubleshoot and if readily available automobile or motorcycle components can be incorporated, this would greatly reduce costs by avoiding the use of 'special parts' exclusive to paramotors. As a first engine, i would certainly consider s small added premium that would become neglibile over time.
'Bailey' in the UK have been producing 4-stroke engine paramotors here in the UK for nearly twenty years, they even use the same GY6 Honda engine as a base, the one Scout has used here (re-engineered crank case). I even made my own machine based on this engine about eight years ago (check out my video's). Good engine, bit heavy though!
Would love to know how this project is coming along.
Me and you both. Will be a good day when 4 stroke becomes main stream
Wow! That engine sounded as quiet as a police motorcycle engine! Very nice! thanks for sharing.
This looks really good.
Of all claims though, I want to see the engine on a scale. 15 kgs all up weight for a 240cc 4 stroke is VERY light, this kind of figure is rarely achieved by 2-strokes of similar displacement.
Can't wait to see 4-stroke engines a regular thing on paramotors!!
New update to this topic here: ua-cam.com/video/biSEx6dU5xU/v-deo.html
Awsome!! I love the Scout gear. Four stroke is the way for sure , I fly a F.B. Trike now with the four stroke Swiss Auto and love the sense of security over the two stroke.

Cool unbelievable cant wait for release
😂
CAN YOU PLZ DO AN UPDATE VIDEO ON THIS ENGINE PLZ THANK YOU
Jan 10, 2020. Any updates? I’m guessing it didn’t go so well. Hopefully someday we’ll have reliable 4 stroke.
What's wrong with the Bailey v5
Interesting stuff! Looking forward to future updates
when can we expect an update on this project?
I've been doing a bunch of research on the engines and that's just a GY6 (150cc 250cc) engine they come in mopeds. it just doesn't have the CVT Drive.
So no fuel/oil mixing required? Does it have a closed oil system or is it total loss?
When will you have this product on the market?
Any updates on this engine?
Awesome. Thx for the update. It looks promising.
What's wrong with the bailey v5? Already a good 4stroke alternative on the market.
1/2 the fuel burn ?? It’s impossible 20-25% less is more realistic . If the specific fuel consumption where so good on this engine , nobody els in the world would produce a engine anymore !
Scout and EOS: "The first true four stroke alternative"
Bailey: "Am I a joke to you?"
Bailey unfortunately does not come anywhere close to the power nor weight of the two stroke engines. This is why I don't consider it to be true alternative
I would like to see Liquid Piston produce a rotary paramotor that is lightweight, powerful and fuel efficient.
Is it available? I don't see it on the website, and two years have passed...
Unfortunately not yet. Still in development. Seems to be more difficult than expected.
Im excited! I would be more excited for EFI though. KTM is releasing a EFI 2 stroke this year which is awesome! The performance as well as range gains from a 2 stroke EFI engine would be monumental.

www.ecotrons.com/products/paramotor_engine_fuel_injection_kit/
can't wait to see one in person.
so 7 months later , do you have any updates yet ? I'm considering to get some PPG training next year and would really appreciate 4 stroke engine after my graduation , i don't like the noise of 2 strokes.
+TerraBiker I very much hope we only need one more week...
One more week for some relevant updates... Still far from serial production.
Do not postpone this sport! Get a 2stroke and have fun. Upgrade later!
What would make the 4 stroke the ultimate would be to have fuel injection!!
Yes you are right... Probably as the next step.
In this age of electronic ignition - EFI would be even less trouble than a carb with it's tuning even with the minor power loss associated with FI. How many 2-strokes in the field are properly tuned anyway? Good luck, Sir.

Very interested, hope it won't take too long before we see it on the market, this is what we want in ppg. Bailey V5 sure great stuff, but heavier, and less power. Great to see Eos working on this.
I start to save right away, definitely something I would buy.
But, I really hope they take a look into fuel injection if there is anything they can optimize for ppg. That would be a game changer if it came in a nice package.
+Casper Nilsson it will take long. It's not fair to let the customers test the engine...
Yeah, I can wait the time needed, I know how many years it can take to make a reliable engine. And always nice to have something to look forward to.
4 years on, any updates?
Hey Miro... What happened to the follow up to this 4 stroke motor?
The project is still alive. We did one update video last year.
Current status:
Exhaust problems solved
Lubrication problems seem to be fine but needs more testing
Engine increased from 240 to 290cc
New cylinder head with 4 valves instead of 2
Now facing some issues with cooling
3 prototypes being build now in the eos factory in austria. Hope to have the motor back for testing soon.
@@SCOUTaviation cheers dude... Thanks for a prompt reply 🙂
Greetings from Sweden 🇸🇪
How did the weight compare? Power to weight ratio?
great to see progression !
push for a dry sump oil system and EFI !
about the 4stroke?? Is it preforming wel now?
I need this now!!
Maybe it was a possibly nice alternative in 2017. Now it's more time to improve electric paramotors. Still loving the video, thank you! :)
Looks like the EOS Quattro 4 stroke is alive and looking to be released soon. Are you guys involved in the testing? Any plans to add this as an optional engine on future Scout purchases?
Big question over current two strokes: Does it run on 92 octane automobile pump gas? Our premium is ethanol free but many places aren't, will this motor be ok on ethanol blended fuels?
Is it fuel injected that would be the way to go as you climb it adjust the A/F ratio.
I would be so great, but still I don't see it for sale on their website... What happened?
Reminds me of my scooter engine. The sound of it. Did this ever get going?
Do me a favour - if I'm not mistaken this is a GY6 157 QMJ based engine - probably the commonest 4 stroke scooter motor on the planet made by dozens of China based manufacturers turning out clones of the original Honda engine it's based on. 18 to 20.5hp depending on what overbore kit you go for. Paul Bailey in the UK did it years ago with 5 versions. Looks like another CNC crankcase and overbore to me!
what happen to this game changer 4S engine?
Nothing. Out.
Hi Miro, whats the news on this engine? Is it going into production? Will the engine be available on its own and at what price?
It still isn't out though, right?
Hi there - Any update on this? :)
Is it possible to supercharger one of these engines to help at high altitude? I know back in the dat the P51 Mustang supercharged it's Merlin engine and that boosted performance dramatically.
Don't think that you should have the intake next to exhaust minor change could put the carburator facing up to get fresh air. Its getting heated air and also less oxygen..!
Lots less noise too with better fuel mileage with the new motor. I was wondering when it was coming out, probable price could be cheaper too! Don't have to wind it out launching it!
Are there any updates? How is testing going?
I agree with fuel injection.... top it up with coaxial counter rotation smaller dual props and you have ultimate paramotor

Can we use 100 cc engine
Any word on when this engine will be available? Any word on estimated TBO
Please make an update video with insights from your testing...you said that you intend to put 100 hours on this motor within two months...and that was 3 months ago. This 4 stroke game changer is such an interesting topic. Please give us an update even if there isn't anything new to share we still want to know what's happening.
Have you tried Bailey Aviation 4-stroke? It is there on the market for ages. Same story: linear, fuel-efficient, quiet, etc. The paramotor update of some classic Honda in fact.
Does not come close in power and weight
Really interested. I like 4-strokes, but Bailey is a bit underpowered for me. Is it possible to compare the tech data? (There is nothing yet on EOS site).
Also: is it injector or still carb? I am very looking forward the injector motors, since I believe it has to improve start and run (the way it did in cars industry).
Thanks you!
March 2020 - Where's this motor at?
Game changer fo sho. What is the rpm range?
I have been a PAP man for 4 paramotors (PA125, F200, Moster and now Thor250) in a row but this 4-stroke would be my ticket to change the frame too! Where do I send the money? ;)
haha, keep it for a while...
You should redirect the exhaust to the rear to reduce the noise.
Wirmish, if you redirected the exhaust to the rear then the exhaust would go through the prop area, perhaps that’s not a good idea. I really don’t know. It sounds like it might not be a good idea.
Yup, looks like GY6 Scooter yet again, but I don't see fan cooling for the oil. Maybe more oil than a Bailey, but essentially looks the same. Same exhaust issues too. Donor Engine costs a few Hundred dollars. Nice $$$.
any more up dates it's 2020 now brother?
Sir what do you think about fresh breeze is that a good motor I'm new to this sport and would like to get gear for normal country cruising not a lot of maneuver
While I would sometimes choose design options I respect other manufacturers.
I am sorry but I cannot give advice which paramotor is good or bad. My goal is to share my reasoning and teach you how to make your qualified judgment what is the paramotor for you:

Today we start shooting another set of videos about frame geometry. Small details that most pilots never thought about but yet they are so important...
So I'm guessing the issue of engine outs is greatly reduced with the 4 stroke? Btw, will this come with an e-start? And are we looking at 6-12 months roughly before this thing is ready to be released, or do you think it'll be 12+ months?
I'd be curious to see how this stacks up against the Nitro Tornado that was recently announced. If I can fly with a 4-stroke I will over a 2-stroke any day. However, I'm a big guy and I need a lot of thrust. I was even playing around with the idea of figuring out how to get the tornado mounted on the scout if possible. LOL
That's seems to be a good engine, for now though I will stick to my trusty 185 monster with over 500 hrs. on it with out a rebuild. Good luck with it, might be the real deal.
As said in the video numerous times: The Vittorazi Moster Plus is the best engine on the market so far. Maybe until this comes out....
Well done. Please manufacture to scale of interest!
have the used a crank weight to help with the idle?
did they balance the crank to prevent vibration?
also
is anyone considering e start?
best of luck
im watching the progress
have a great day
No two stoke oil, lower fuel burn, flat powerband, lower noise, lower rpm, clutch, ....wow should I go on? If the power is truly comparable as is the weight this is a no brainer. Longevity is the key, I would imagine it has a 12:1 compression ratio to compete with two stroke power which would lower reliability somewhat but a two stroke already has a short life because it works twice as hard to do the same thing. I am excited to see this.
electrics will retire all i.c.e. engines to the scrap heap of antiquity!
G Morehouse: Not till charging takes as long as filling up a gas tank.
Waiting for an update on this video. Im not an engineer but I believe with time this could be fuel injection too.
We participated on this project years ago as testers. Everything I said in the video was true but the engine had reliability issues and we came to a conclusion t was not ready for the testing phase yet. We stepped out of the project few years ago.
The manufacturer (EOS Austria) continued the development and now they are releasing the engine to the market. I hope they succeeded to fix the issues. I will want to get one for sure. But right now I want to finish our own ongoing research and development projects before I get my hands on this one.
Go get it and tell me:-)
How soon can we see more of this new engine?
In a week
that was 3 weeks ago. I've got a wad of money waiting to be spent on that engine. if its more than about a month i will be forced to buy something different. when can we get it? PLEASE!
How long until we can get one
3 Kids? Good on you! (Me too ;) )
Trochu moc záběrů na ukecaného :-) designera a málo na motor - chce to vidět ho ze všech stran, parametry atp.
Plus no stinking/clinging 2 stroke oil smoke! Four strokes tend to run on the same sparkplug for much long with virtually no fouling.
how about increasing the compression, but adding a flywheel weight for good balance and helping keep a consistent idle.
i would rather not sacrifice power.
titanium exhaust would help too.
as far as engine internals usually a forged connecting rod, crank ,and piston and good size bearings
stainless valves are tough too
cheers
+dimitri we already have a ton of new updates. Wait for the next video...
Please put the lid on the plastic that goes where the spark plug goes. That lid is when you're at -32 farengein.
Sounds like a lot more fine tuning necessary before sales.
Any updates on the production status for this motor? :)
Just saw the update video! Looks promising. I hope it all works out. It sounds like you are wanting to implement something similar to an oil catch can :)

Any upates on this?
Děkuji Miroslav... great update 😊
+Heis aPilot we have some more stories to add already. Things are moving with this engine...
Sounds fantastic mate!
cheers..
Has nobody ever heard of Bailey? They've been making 4 stroke motors for years, i'm going to fly mine this afternoon.
+General Disaster sure we had. I was even considering that for myself. The weight would not be a big issue but it had little power.
I have been waiting for a powerful 4 stroke for long...
Maybe more poweful than previous offerings, but hardly the first viable four stroke alternative. Bailey have been doing it for years.
+Phil Passmore sure not the first 4 stroke, but the first one to really match the power and weight of the 2 strokes.
Would a turbo charger add to much weight?
We need to keep things simple. at least at the beginning.
Sooo. no nitrous oxide then I guess.. (kidding)
Why wasn't it tested with a three blade prop? Wouldn't it have been quieter, smoother and improve overall performance?
Whatever happened to this engine? A year and a half later I cannot see it on the website, did it not work out?
Could it compete with a direct injected 2 stroke?
+David Vermillion there are a few experiments with fuel injection on two strokes but none of them made it to serial production... At least what I know.
How is this working out now?
It's a piece of crap
The top end looks exactly like a Bailey to me. Are they the same?
+Scott Harcourt the EOS is derived from Kymco scooter engine
SCOUT paramotor so thats a yes then !
what's your average speed when u burn about 2 litter fuel per hour?
Price?
i fly over 400 hours/year most of time,for this don't have to mix be great,also in bahamas gas is around 5 $ gallons.
Love the sound of that engine! Any updates yet?
Ditto, updates please?
Es ist nicht zu verstehen warum wird dieser Flachrippenriemen verwendet und nicht gleich ein Zahnriemen?
Update on theEOS PLZ
+Sabaoon Sangar flown it today (again).
Just quick update: new carb, new oil routes, new exhaust with 27 hours without breaking...
We have some footage to share but we will not be able to edit for two weeks (vacation).
Overall good news
AWESOME THANK YOU SO MUCH CANT WAIT FOR THE NEXT VIDEO
You have for sale now? ..
Far from it.
New cylinder and head to be tested now.
Capacity increased to 290cc
