A brother of mine used to fly gliders. When he was learning, he was flying alongside his instructor (separate aircraft). They were running out of altitude to make it back the their field. The instructor said "follow me", then stuck the nose down and flew quite fast in ground effect, rising up to miss hedges and trees, and got back to the field with quite a bit of spare speed in hand.
Ballsy move in a glider, a bit of wing flex and that sh*t can go real wrong
Even noticeable in a hang-glider when the wing is a couple metres from the ground.
@@afrog2666 Wing flex? What are you talking about? Glider aerobatic demonstrations rely hugely on ground effect.
GIGACHAD HOLY

There is some poethic appeal to flying so close to the water surface... simply beautiful!! Congratulations, guys
The closeups skimming over the surface of the glassy water are just sublime. I can't imagine what it would feel like to actually fly in a plane like that. Closest to a "spiritual" experience as I can imagine.
Learn to hang-glide !?
Absolutely amazing! I remember watching Daniel, as a kid, flying one of his homemade planes, out from his bedroom window, to a distant mountain, and back through his window. You, two, are absolute geniuses. 👍👏
Just FYI, in the aerospace industry, our metallurgists typically have us using LPS-3 inhibitor for general applications. CorrosionX products, including HD, have failed their salt-spray torture exams in the lab, like nearly all consumer-type products do.
thanks for the tip, on order...
Really impressive. Thanks for including the rough weather conditions, handled it much better than expected. Also just beatiful pictures, the reflections and all, wow.
Finished project looks beautiful, it does have a “ocean ray” appearance. Those props are doing some serious rpm’s, they sound gutsy. 🧐
Fun fact: "Ekran" is a soviet innovative word. It means the air buffer between the plane and the water surface.
Here is the one good model developed back in 1987 en.wikipedia.org/wiki/Lun-class_ekranoplan
@@sergouss I was there this summer, saw that soviet monster with my eyes and almost cried of his unlucky fate. Hope someone will continue the history of экранопланs
Btw "экран" means "shield", in this case its air shield / buffer
Thanks for reminding me of VNV Nation. It's been a long time, and it's great to see they're still making music I love.
This is a beautiful project and well documented. Congratulations on the work. I am a long time modeler and am still astounded by the newer generation and how much you guys can accomplish. Keep up the great work!
Nothing like a little lake effect flying. Absolutely wonderful.
Heart felt for you when you lost a week solving ESC issue. Talking us through those kind of problems and how you solved them would be interesting. Thanks for the great videos!
Man, just wow, this whole project is amazing. Having designed (conceptually) an Ekranoplan myself, its amazing to see prototyping and testing at this scale. Congrats!!
Is the concept all in your head, as I couldn't see anything on your channel?
@@ruzziasht349 no no it was part of my masters thesis
At this scale? You mean tiny little teeny toy scale? What was your model, only drawn on paper?
are you guys fucking high...you did your masters thesis on a concept thats already full scaled in production? czcams.com/video/-r7mFSq8PRU/video.html
I've been flying RC for 40 years. It makes me very happy to see young people using innovated technology. Good job guys! 👍😀🛩
This truely one of the prettiest model aircrafts I've ever seen. Great job
I'm floored this is so Awesome... You all are so Awesome!!!
In case someone is wondering - the song is: When Is the Future by VNV Nation
That's gotta be the most badass ekronoplan I've seen, thus far.
This proves the old saying correct "You never stop learning". I'd always thought or assumed that ground effect vehicles could only fly close to the surface but you have opened my eyes some what. I can only imagine flying or navigating or driving this machine and its versatility. Great stuff, thank you.
If he can build a full size WIG craft that can carry 8-10 passengers and navigate over 5'-10ft seas it will overfly all the current WIG craft I've seen fly.
Stunning. I was mesmerized. Just beautiful. Thanks for posting.
Damn, amazing. The engineering and Daniel and you, three pillars of the hobby.
Always glad to help with cool projects. Great job on the build and video!
Thanks man literally couldn't have done it without you.
Awesome craftsmanship making the machine, but even more awesome skills, filming and producing the video. The images taken are beautiful, great job!
I'm so glad the cameras can do justice to your wonderful creation.
Gorgeous footage with that water mirror and mindblowing sunset!😍💜🥰
Daniel of RC Test flight is more of a "I've got an idea!" and two hours later he is out using math and electronics to fly a pizza box above the lake. I really like his channel and to see the ideas he has actually take life. This collaboration seems like a great way for us viewers to be able to see how the ideas and proof of concepts can perform when refined.
What they are doing is an absolute beauty !
I think that’s what we all love about rctestflight!
Well, the USSR developed real ekranoplans in 1975 GEV
so much science and so casually done. Love it!
Awesome project. Great work. Thank you for sharing!
WOW, that was amazing!
Really great result of the collaboration between you guys. I was particularly impressed with the rough weather testing, if scaling up proves accurate then the full size vehicle would be able to handle sizeable waves in ground effect 👍
This is definitely my favorite RC vid of the year. Also you have great taste in music =)
Congratulations! What an amazing project!
Be cool to see amps drawn when transiting from regular flight to ground-effect flight, at a constant speed.
How far you have come since the days of trying to get a Tupperware container to avoid the sea weed and find its way to your final waypoint. Nicely done!
Beautiful plane. Congratulations on your success. Can't wait to see more as you improve it.
A very well done on the beautiful videograophy which brought it all together!
Amazing work. Congratulations to both of you.
Fantastic job. This is impressive!
this looks like a game changer, I would love to experience flying that...
Beautiful. Thank you for sharing this.
Awesome smooth flying 5 cm above water. Congrats for this achievements.
Congrats to this awesome build! Like your collaboration with Daniel who is a great inventor too :o)
It’s a pleasure to watch a video with engineers that clearly understand the principle or have at least researched the issues associated with the project and not only have you guy designed and build a very competent flying machine but it’s also a work of art and beautifully presented in this video
Really great work! Protect yourself, as best you can, to make sure you don't get ripped off!
Nice work brothers , Respect ✊! Keep going to the edge and beyond !!!
Whopping well done. Superior level of craftmanship and engineering. Will you manage to bring the ekranoplanes back to life?
Supernice edited and music as well!
Let's hope modern Americans aren't too afraid of Russia to embrace the technology they pioneered decades ago ... 😂
What a damn beautiful craft!
The elimination of porpoising is super impressive. So smooth!
WoW! That's an incredible vehicle! Well done!
Love that song you put in the end while you were flying! It fits like a glove 😊😊
I remember "designing" ekranoplans in X-Plane for the lols. It was most difficult to exploit ground effect in a simulation, not explicitly designed to do so.
Glad to see that the company is still alive and kicking and has apparently taken important steps forward addressing the main issue with stability in ground effect.
It has become clear that it is virtually impossible to design a self-stabilising and efficient WIGE craft capable of mastering varying real-world conditions.
Your contribution might seem playful to some, but others will consider it cutting edge applied engineering.
Kudos!
I found it a bit odd that 'the company' gave them pretty much open ended design freedom, and sounds like they came up with the design!!!??
So the company, that's been working on this for some time, didn't even have a concept design????
@@pawspaws101 it has. This configuration of an inverse delta in ground effect is very old, first designed by Prof. Lippisch in the early 60's and first "flown" in 1963. It was subsequently developed into larger more capable (prototype) models that culminated in the design of the company talked about here.
I wish the Wright Bros could time travel and see what you guys have done.
Nice! Thanks for sharing!
DUDE,! you guys are awesome !!
Spectacular footage!! Might have been cool to fly from the water surface over the flat beach and back
*We need competitive professional Ekranoplan racing!*
And battles

Awesome!
SUPER EXCELLENT VIDEO.
HAPPY FLYING!
I love it! The way it Looks and at most the way it flyes over the water. ❤️
Excellent design & build. Spectacular images (that banked turn dipping the wing at 11:40 & the sunset @12:45 !). Collab with another legend (Daniel). VNV Nation in the soundtrack --> Subbed :-)
Great stuff. Still very keen to see an some efficiency tests to show the energy savings by being in ground effect!
Yeah, and once you realize this would never work at full scale, you realize it is a huge fail.
@@VidarrKerr this does work at full scale. I don’t understand your comment.
@@toxaq Bro, it is a tiny little model plane. That is NOT full scale.
@@VidarrKerr I'm aware as I watched the video. I've asked for data to see how useful the effect is at this scale. You stated "this would never work at full scale". I don't understand how you could state this as there are plenty of ground effects vehicles at full scale. So I'm wondering what you meant by your comment.
@@VidarrKerr You do realize ekranoplans get better the bigger they are right? both in efficiency and in stability
Congratulations. The drone footage on this is fantastic too.
So good! Amazing job guys!
You get an extra thumbs up for using VNV Nation's song ;)
Finally RC ekranoplans/WIG vehicles are getting some attention! I have been building these for years doing all sorts of experiments which has been so fun but there has been such a lack of interest every time I share. So it is really fun to finally get some cool content on these!
Pete sripol made one
czcams.com/video/ifllgTA2pmY/video.html!(!
I checked your channel, you have nothing.
@@ruzziasht349 I never said I made videos I said I've been make RC WIG vehicles for years.
@@willowehrich6207 It's much, much easier to make a video (to prove what you've been doing), than to make and an actual WIG vehicle.
Well done, what a gorgeous aircraft! ❤
Ekranoplan and VNV Nation. My mind is blown for the day, thanks. :)
I hope they paid you a boatload (see what I did there) of money for your IP. Getting their machine working is probably worth at least a million dollars of VC funding to them! Wonderful work, you two are just amazeballs. #ArdupilotFTW !
yea pretty much. if your designing and making their test model
yea no kidding... highly doubt they paid them even close to enough, akin to "i can trade you for exposure"
czcams.com/video/ifllgTA2pmY/video.html!=!
@@tofaanshinwari6431 Stop spamming
Impressed with these craft. Tail out of ground effect? What about a canard version instead?
Canards are pretty unstable and how would it perform if it was in ground effect?
The reverse delta already is one of the more stable forms for ground-effect, but with small aircrafts you really want the extra stability that comes from the surface that is further away from the ground.
Canards would like have a similar problem as the wings - their effect would vary greatly depending on how close to the ground it is.
It’s obvious you had as much fun making the video as you did the prototype. Nice job all around!
I had to come back and watch again. Very cool!
To explain the concept in simpler terms, it is used by pelicans skimming over the waves near the beach... apparently they've known about the WIG effect for eons. :)
It is also how most big birds can slow down to a few km/h before landing
I mean - noticing the effect is basically guaranteed - any aircraft that has fixed wings will experience it during takeoff and landing.
czcams.com/video/ifllgTA2pmY/video.html#
@@tofaanshinwari6431 Nobody wants that bullshit here.
@@ABaumstumpf Yes, but WIG craft are specifically designed to fly in the effect efficiently.
please make this a new flightmode and add to Arduplane! people would love this!
I hope it gets added too.
A joy to watch. Thanks
Great work guys.

Of all the channels I subscribe to, this is the video I have been most anticipating since your first installment. Have any plans for your first craft? Put the same system in it? If you don’t have plans for it, let me know. I’m interested in getting it to the fully autonomous stage, flying waypoint missions including takeoff and landing. Great work. Great collab! Your fabrication skills are praiseworthy.
I don't have plans to share for the first one, this one is completely different in every way though. You should go for it, these things are a hoot.
@@thinkflight would you be willing to send me the airframe if I cover freight charges? Or let me know how much you would need to part ways with the airframe and onboard electronics (receiver, servos, anything that might difficult or help impossible to remove. ) you
I have a selection of autopilots, sensors, batteries, and transmitters. I’m an electronics engineer and embedded systems designer/programmer. I just don’t have mad fabrication skills you’ve demonstrated, though you have inspired me to develop those skills over time.
Best wishes and keep up the good work!
Great video, Thank you! Love Ground Effect stuff, very interesting.... Also a note- This video got me into VNV Nation! Never heard of them before.... Perfect for your flying shots!
Wonderful! Must get on and try again to build one myself! Congrats!
Kudos!
Handled those moderate chop and wind conditions much better that I expected. How far will you push the envelope on this, any plans for autonomous sea trials etc?
Yeah, and waves doesn't scale, those were som mountains if you take scale into it.
On a fullsize craft the waves are more like ripples in the ground
@@someoneelse7629 I would say that survivability gets worse with increased scale because the length, area, volume, strength, mass, velocity & Rn ratios involved in scaling, full size things tend to be more fragile for their size than models.

I never thought I would be that guy but please don't run up your props while standing eye level in front of them without any safety glasses. I've had prop nuts let go before and I can tell you the propeller travels forward in a straight line really fast when it happens. Aside from that you and Daniel did a great a job. Keep up the good work.
Very cool design, great job putting her together and piloting!
Hypnotic watching it fly!
Awesome build, I was always fascinated by the Ekranoplan and ground effect aircraft. The main issue I see is that an upscaled manned aircraft would most likely not use electric motors and therefore couldn't get responsive enough motor control to keep the altitude, so that would probably have to be done by the elevator. Of course I would love to see an electric solution, espacially as weight is much less relevant compared to normal aircraft. Keep these colaborations going, great stuff!
In larger aircraft, independent canards controlled by electronics would be the most likely candidate to take the place of throttle modulation for a more direct attitude control, while the elevator would be used for more traditional attitude changes. Minor correction would really be all that you'd need, and that can be accomplished with canards no problem. Larger aircraft have a tendency to be a bit more stable as well, perhaps not the best use of the word in this case (not as sensitive?), but flight path and attitude changes can be made more gradual without microsecond adjustments due to inertia and momentum. A quick youtube search of Kevin Quinn's waterski record, or any video of an ag plane spraying a field illustrates how stable they are without any sort of attitude control beyond pilot input in comparison to small RC sized aircraft. Even with a good 6-axis gyro/accelerometer, most RC planes can barely approach that level of smooth flying even with a good pilot, and it took considerable effort to design a system that works as well as the plane in this video.
Popular Mechanics Magazine had an article on this principle and they actually had a manned workable model flying feet over the water. This was 20-25 years ago. I was really intrigued by it because it had excellent business potential. I never heard or saw anything about it since.
Wow, well done guys, incredible !!
Looks great and works pretty well. Congrats
Question: Was there any noticable amount of efficiency when is G effect vs flying around? if so,what kind of percentage?
Yes drag goes down so efficiency goes up. Can't give you numbers though
@@Veikra i am expected efficiency to go up. Id like to know by how much. Ground effect craft are kinda niche market and need to prove a lot if they are going to catch on.
Yeah I'd like them to run a few battery tests at least, one flying it as a plane, and another at ground effect and use flight times as a metric for efficiency.
@@bucklogos exactly!
Ground-effect aircrafts are really interesting, sadly scaling them down does not work so well for flying over water as the effect only becomes really noticeable once you are very close to the surface so waves become a big problem.
The optimal height depends on the size of the airplane and I suppose some other factors but the Caspian Sea Monster hat an optimal ground effect at 20m height.
@@Garium87 "The optimal height depends on the size of the airplane"
Yes, hence why i said that downscaling has serious problems as you need to get closer and closer to the surface to get noticeable results, getting ever closer to the wave-tops.
Excellent video! Thank you
Awesome project guys! This is great!
How does power consumption compare in ground effect vs normal flight? Is there an advantage?
I would love to see this data. Once in ground effect mod the increase lift would require much less propeller push. I would guess is a trade of speed x efficiency in this condition.
A proven design, though it has been 50+ years since it was used. I was wondering if you put the weight of the full sized machine to scale also? The control system in and of itself is quite amazing.
With scaling down a model the behavior is much more sensitive compared to the full size one. In RC planes and helicopters, the larger the model, the more stable it is, so if anything, this video shows that the full scale one would probably be very easy to control (like you said, a proven design).

That is a beautiful machine. Congrats on your accomplishment. Amazing.
Amazing work guys. brilliant.
I've found this type of aircraft extremely interesting from the time I saw reports and videos of the big Soviet aircraft. The fact that they never built more of them, must have something to do with envisioned operations, cost. and political issues. As a layman, the first commercial application of this type of craft that I can see, is transcontinental, and Pacific Ocean area passenger services. If massed produced models can prove that they can be commercial successful, Eco friendly, and cost effective vis jet airliner competitors. The world could have a new way of travel in the future. Bottom line.. can a profitable business model be developed. I'm impressed with the construction of the model in this video. 👍👍😊
Beautiful model .... excellent flying
Everything about this is achingly beautiful.
Incredible construction and desigh! Result is a beautiful air/water craft. Thanks for sharing.
Fantastic !!! Great great job .
Inspiring, great work. You have a real skill. The GEV, the video and the photography. I found the 4k stream and its really well done in those flight shots. Respect is due.
Your channel is amazing! I can't believe you don't even have 100k subs. You deserve many times more than that!
