Daniel’s gotta be the Snow White of the RC world with all these animals coming to check his stuff out
i'm a big fan of your last video :)
Or maybe Dr. Doolittle; "Get the ___ , whatever you are" !
Seeing as every time he shows himself in a video, he needs a haircut, so I would think he’s part Rapunzel

The Bever makes this video so good lol, my man was chilling
Should have given the beaver some factor in the #ad😂
"That Beaver is trolling me" lololol!! Imagine the stories he had to tell when he got home. "Y'all ain't gonna believe what I just saw!!" HA!! You've done excellent work. This design is so amazing. Keep at it! :)
Beaver kids: hey dad how was your day?
Dad: don't ask. Some stupid ass seagul kept flying over me. Must have thought I was a fish.
For someone who doesn’t own anything RC, the AirFoil Saga has been very entertaining and interesting. Love how the videos have sort of been evolving and now there’s wildlife popping up at ur spot haha. very cool videos keep ‘em coming!
I feel like you need to turn the vertical stabilizers into rudders for turns so that you don't have to rely on roll and par thrust to turn as those tend to cause one of the wings to dip into the water for anything more than a shallow turn
Rudders are definitely a must for turning this thing. It just doesn't have enough room to roll in.
Hydrofoils!
Please please duct something like an EDF to the underside of the wings, distributed underside ducts along the front edge, facing rearwards, to really ram the air into the right area for generating separation between the water and wing/fuselage. I feel like you could really isolate the effect with something like this, over forward mounted props. Even if you just use ducted air for the basic lift/planing and a separate prop for forward drive....
That’s basically a hovercraft
@@shize9ine is it? The main difference being still no skirt and the air is in close proximity to an aerofoil (unlike a hovercraft) and that may be significant. Maybe ducting further back towards the trailing edge would be better.
@@shize9ine It's channelling the air not trapping it under a 360 skirt.
Why don't you do it Simon,be great to see
@@M-H433 my skills are a long way off doing that, and closing the skill gap will have to get in line behind all the smaller gaps I'm trying to close.
I really like that you show the full experience with the wildlife. Feels as if I'm there, except I don't have the hassle of actually building stuff and having it break
I guarantee this channel is responsible for hundreds of future engineers
Awesome stuff, I really think a larger scale is on your side with this design and most of your 'issues' result from it being smaller. Maybe increasing weight and power would allow for smoother ground effect and also a higher ground effect ceiling as more air is required to be compressed to gain flight. Also I'd love to see if a vertical control surface coupled with differential thrust would help with the large turning circle or induce other problems like rolling or drifting. I really think you're on to something amazing here, keep it up!
I was going to say the same thing.
i think a rudder would cause adverse roll unless it was at least nearly symmetrical
@@slothFPV the FC should compensate roll with those elevons
Peter stripol made a big one that worked decently.
I'm always thrilled to see an update from you. Fantastic stuff.
IT'S SO FAST! Could you put some dynamic aero under or through the body that could create a kind of dynamic spring for chop? Maybe that sounds crazy. Like if you pair the ToF lidar heigh sensor or even just measure with the accelerometer for chop and move some dampaning baffles. I dunno. Seems possible in my head. Seeing how fast this thing is man, you gave me a bug here. I've been working on a little camera boat project and have been wondering what the next step is. Ground effect plane. Sweet.
i was gonna comment qbout active aero on the underside :D good thing i looked first
The elevons are providing a kind of active aero but could probably be tuned better?
I have been enjoying your ground effect series. I like systematic approach to problem solving.
Thank you for posting
I found your channel a week ago and I'm hooked! It's fun to watch you experiment. Great to hear the F1 comparisons, too.
Awesome vid with all the experimentation and commentary. It was fun being brought along! I look forward to seeing what some time apart from the project will bring to the table once you take another crank at it. Thanks for the vid!
Am I the only one who is fucking hyped about the Beaver?
Video is also awesome!
For an alternative pov, go visit the beaver’s TH-cam channel.
This is cool! I love how it looks when you get up on the ram effect and just start cruising. I'd call this one a success.
I can't say for certain because I haven't used this myself, but I think I'd prefer the craft if it had at least some of the horizontal stabilizer. It seems to be easier to keep it stable without the PID (at least until you add the extra weight) when you have it. Some things I'd want to experiment with are different sizes of H. stabilizer, spoilers for the H. stabilizer and/or the main body to try and eliminate aerodynamic lift, and using "flap rudders" (rudders that work by extending a pair of flaps from where a rudder would be) to see if they can create similar turns without having to use so much roll or differential thrust.
Can't wait to see what's next!
Your footage is beautiful and pleasing to watch. A joy to see!
Your content is some of the best stuff on all of TH-cam! I can’t remember when I first found your snowcat video, but everything you make is so interesting! I also really appreciate how much you explain the science behind your projects! I also love when your friend makes music for your vids! Please keep them coming! Huge fan here! 🙋🏻♂️
Dude-this is an incredible design and build. Im seeing really big things happening for you with your ground effect craft. Well done.👍
This is still better than F1 ground effect cars' porpoising, pretty interesting build!
What even is the link between these 2, one is the Ram effect, the other is using downforces
AMEN!! Which do I prefer? Watching millionaires use CAD and wind tunnels and exotic materials or a determined young inventor with foam board and a glue gun? Here I am!!
Gotta add a quote: "If you want to make an apple pie from scratch, you have to start by creating the universe first." - Carl Sagan
@@Simon-jv9bm The Venturi and Bernoulli effects that he describes at 3:32 are what make the F1 ground effect designs work and produce downforce. Of course the F1 cars do whatever they possibly can to avoid creating a RAM effect because they want to ride on a cushion of rubber (the tyres) instead of a cushion of air. In either case, both are types of "ground effect vehicles" but with different intended functions and focuses.
EDIT: The porpoising under F1 cars also isn't caused by competing ground effects like we see on this vehicle, but by the car body getting too close to the ground, cutting off the Bernoulli effect and causing the car to lose downforce until airflow is restored and the Bernoulli effect kicks in again.
Couldn't you steer it with rudder, instead of ailerons and differential thrust?
Question: For the 'wet lens' problem, what about attaching a very small tinywhoop motor just under the camera to just blast high pressure air on the camera to clean the lens off? Maybe a 3D printed cowling could make a 'bubble' of air over the lens, which would maybe deflect some of the water.
Ive heard of filmmakers using a spinning lens cover so as soon as water hits it it gets spun off.
@@eulogyguild I was trying to keep it cheap, and simple to make. I have seen those spinning viewports on milling machines for manufacturing, but I think a tiny thing would have to spin at several thousand RPM which would be a whole other problem to deal with.
Or, we can blow air at the lens with a tiny propeller and motor.
Outdoor kart drivers use a clear free-spinning disk in front of their visor. It has vanes on it to catch the air, which spins the disk as they drive.
Update: they’re called turbo visors
I've heard rain-x works well
Spin disks are used on automated industrial milling machines to look through the windows while coolant/lubricant is being sprayed everywhere. He could make one under 5 minutes when at the workbench with a circular piece of clear plastic and a small brushless motor. Should be a non-issue and solved with things he is likely to have on-hand.
It has been really fun seeing your progress on this. It seems now you have a true beaver-effect vehicle. :)
I now know so much about ground effect thanks to all these videos.
Wow.. been following these for some time and they continue to get more and more incredible.. 🙌🔥🔥🔥🔥
I watch all of your videos as soon as you put them out. I would love more videos out of you but I know your stuff takes more time. Keep up the good work. I have a DIJ FPV drone your stuff really makes me want to try more DIY stuff.
use drag to turn sharp, it would also act as a stabilizer at the same time as it skims the water surface.
Love this! Your content is always incredible. Can't wait for the next rover, solar plane, or autonomous boat mission!
Consider the local airflow rearwards and upwards of the wedge wing - it is flowing down. So if you have a globally flat stabilizer, it locally pitched up by default.
Love your appreciation and fascination of nature (geese and beaver and all). I'm the same, it's just soooo cool!
Love this channels content, relaxed but relevant tone is great!
I always feel that suction force pulling the plane down during short field takeoffs in the Piper Seneca. you can really feel the pull when you rotate and the struts compress a little right before it breaks off the surface.
I've been a fan of your channel for several years now. I have an Autel Evo that with all the rules and regulations I haven't flown it in months. I'm in the process of setting up a FPV system on my Arrma Kraton not liking 5.8ghz. not sure if 413mhz. or 1.2ghz.
One of my favorite video was the time you flew the plane while following it in the car. I really enjoyed flying FPV just to see how far I could go which my record was only 1/2 mile. Now I am trying it on a ground vehicle. Looking forward for the next video.
2:09 that low pressure zone is actually at a higher pressure. Its acting as a divergent nozzle.
Look up the effects of a convergent/divergent nozzle with both subsonic and supersonic flows. Bernoulli states that at a subsonic flow, a fluid at a given pressure will increase its pressure through a divergent path/nozzle.
Always seen that the ground effect was also depending of the wing span. Increasing it could allow you to produce more ground effect with lower speeds required and more lift (but therefore more drag too)
Loved this mini WIG serie, some very interesting observations there👏👏
Super video + I admire your dedication: 5:30 am with mosquitos swarming. Looking forward to what you will think of next.
Thank you!
A few things I would like to see as experiments on this small depron unit: Motors on the corners of the nose!
Using the prop-vortex to seal the pressure. I think massive gains are possible. But who knows, maybe it'll be unstable or something.
And IF you have a (passive) horizontal stabiliser, put it at motor height, in line with the motor, to even out the forces. If those are in line with the "wing" it should still not want to "fly", but hover at speed.
Maybe even delete the fuse... place the battery on top , or split the battery. Make the sidepods slightly more buoyant, and have the motors directly in front of them.
(Not that useful, if the goal is to have a manned version.)
Learning a lot about GEM. 👍🏻
Two questions: 1) I know “how to” videos aren’t really a thing you do on this channel but I would be interested to see some content on waterproofing a cadex. 2) when you switch from futaba to DJI/cadex, why use the DJI controller vs something like edgeTX and crossfire? Wouldn’t you have more control with your model and modes? I ask this question as someone with much less experience but find myself in similar circumstances. I build several models/craft and sometimes consider having the DJI controller but I feel like having a more open source TX provides more versatility. Again, I know this deviates from the content, but I would be interested to hear what drives these decisions.
absolutely amazing!✈
This was just a fun video to watch! Great job!
Cool man. I've been watching some of your videos. I never watch anything longer than like 5 or 10 minutes but you keep me pulled in the whole time. I live your channel.
Another outstanding video! You are a gifted inventor / engineer!
Love the wildlife shots and trolling beaver, adds a lot of variation to the video
Reminds me of a hover craft, very inspiring to me as I love boats and planes .. thanks for sharing
I get so excited when you make long videos!
Wedge concept: brilliant.
Hi! Have been watching a lot of your ground effect stuff. Have you tried / have it been discussed to use a water foil in front of ground effect vehicles to help with breaking from water? Quite small and shallow waterfoil most likely.
I Like the videos very much! Huge thanks for making them!
That fpv footage is really cool.
Great video. Love the ground effects videos. The snow cat is also great. Thanks
Hope you get back to this soon. You are making real progress in an area that was stagnant for decades. Removing the rear wing was a huge step forward. Would have liked to see another video about tuning the elevator. If you want to build a human sized one, you can live at my house, build in my shop and fly from my dock in Florida.
The way you plated the factor mac n cheese with broccoli would cause a chef physical pain, 10/10 I love it.
Food looks good so you let it speak for itself!
Fascinating as usual.
Excellent work!
Beaver always causes problems. Really cool and your design seems to work very well. This gives me some inspiration and a way to use up the large sheets of corrugated mounting board and old Futaba surface radios I have laying around.
There were turboprop versions of the ekranoplane - maybe those are the best design examples that would translate to model building. The final versions had a prop at the top of the tail, which would tend to keep the nose down while holding the high pressure portion of the wing near the water. They also had large flaps, which must have been an important part of trimming the wing for efficient cruise, as well as take-off.
@rctestflight just as a point. When you microwave a ready meal, put a plate underneath, otherwise the microwaves struggle to get to the underside. Makes the cooking more even
It seems you may want to investigate the vertical stabilizers further forward, maybe even with the rear wing.
Would be interesting to see if possibly adding 2 more motors around the cg point in a fixed mounting, with the front ones able to pivot left and right for more directional control.
KEEP DOING WHAT YOU DO, Thumbs up dude !
definitely seems like you're making some solid progress on this flight regime
You could make the upper wedge of the foils variable, this will vary the downward force helping with variable weight loads, or if you make it independent on each side use it as a turning mechanism. 👀
Pretty awesome! I do have a question though, is there a reason that you are avoiding having a tail rudder in favor of differential thrust? From my novice view it seems like constant thrust with a rudder (or pair of rudders) for turning would make for smother turns maybe?
Rainx is good for keeping the lens clear 👍
Very interesting video, cool design, great-looking craft, and lots of fun to watch. Adding the camera ratcheted up the the fun of watching. Great job and nice narration, too.
You should try putting a edf in the wing on both sides to get it up so you can get a air pocket with that for low speed ground effect and move the motors out farther to turn with differential thrust better I think that would be interesting to see and it would probably be able to hold more weight
You could totally make an awesome racing series with these...
I hope this series just keeps going.
Nice project and presentation.
This is regarding turn radius.
1. Is difference left right forward thrust offered a desirable turn radius?
2. Is difference motor tilt offer a desirable turn radius?
3. Is mixed elevator-aileron offer a desirable turn radius? Caveat: over steering into violent spin.
4. Consider rudder channel controlled “dip (left/right) tip sticks” to skim water surface to produce drag to aid reduce turn radius.
5. Consider mode change from GE to airborne to enable a banking turn.
6. Airborne mode capability can help get around surface obstacles too.
Hope this helps.
Try making the bottom of the wing round so the ram effect happens more on the front and you might have a better ground effect control loop.
Science with clear and concise insight. Novel engineering. Epic camera shots. Silly animals. He's got the formula down.
Dude, this thing is awesome, and looks perfect for me to have some fun with! No terror of crashing with an airplane, or with a boat. Do it right, and it's almost impossible to flip or lose.
Maybe you could build a makeshift wind tunnel, using fog machine, fans etc, and then you can test your theories about the airflow characteristics.
Flow-vis paint could be an option too
Your videos are just amazing.
You can put rainx on the camera lens to allow the water to just come right off
FWIW some IRL Ekranoplans are quite capable of flight out of ground effect. The Russian A90 had a ceiling of 10000ft, and the early-2000s Boeing Pelican concept would have been able to reach as high as 25000ft. They generally lose efficiency when flying, but it enables them to use conventional airports.
RainX windshield treatment on your lenses will do wonders keeping water off lenses
That's the best ground effect I've ever seen
To keep water off the camera you can coat is with either rain repellent or that oleophobic liquid for cellphone screens. A more mechanical way of doing this would be similar to large ships or CNC enclosures: a glass disk right next to the window (or camera in this case) that spins really fast, slinging off any water that splashes on it.
Rain-X was originally developed for aircraft use, just makes sense for FPV camera lenses.
@@ultratorrent Was it meant to be rain repellent for just windows, or an anti-rain/anti-freeze wash for the whole plane (what glycol is now)?
Old cassette tape segments taped to the airfoil are the best flow indicators, unlike string and yarn tufts recording tape is waterproof.
Well congratulations I suppose. You've got me well and truly invested and interested in ground effect vehicles.
What an AWESOME model.
I think if you can (more effectively) direct the prop wash under the "wing" you can increase the air pressure and fly slower, or at least break away from the after earlier.
if u were to add a rudder and just connect it with thrust vectoring thingy then when u r turning the rudder will go in that direction just a thought to reduce the turning circle
I love seeing the animals popping by.
For tell-tales (the strings) many short ones will be much more effective at showing the airflow than a couple of large ones.
2-3" long is where I'd start.
13:50 those are some dope floating houses
So wanted to hear your latest song release! Was waiting for a good beat with some clever Beaver and Geese references.
You could try some Rain-x on your lens or on a protective screen
Love the video!: If you only need the triangle for the ram effect, then what is the big back wing for?
Can you do a flat “rudder turn” to help maintain max altitude and improve turning radius? Maybe even tune out the roll bank with the flight controller and have a small rudder on the front as well as the back to help pull it around?
You could try putting rain-X on the camera lens. (making the lens hydrophobic works really well at keeping small dome shaped lenses such as on an FPV camera free of liquid;
In my experience, the limiting factor for FPV then becomes visibility.....heavy rain and fog are pretty opaque and or dense......)
I have used it with no issues on run cam racer series as well as a few no-name camera lenses, but YMMV for other brands( it might damage any factory anti-glare or other coatings on the lens, if there are any)
That is it! That is definetly a ground effect vehicle! It glides really well above calm waters, and it's SO FAST! Omg I was worried about the geese hahahahaha
Looks really fun to pilot! Have you ever tried it on another surface, like a road? Does it glide above that?
As a suggestion: Name it "The Dalek" as it seems to impeded by non level surfaces
We should be concerned when it starts yelling, “Extermiiinate!”
Most entertaining video I have watched in a very very long time. I love to watch videos that approach problems and have the same goals that I can only wish to have time for one day. In essence I vicariously live my hobby life through guys like you. And all the extra video material from the Animal Kingdom only made it that much better. Now I'm just waiting for a Chinese company to see your video copy the design and make it available to me by next year. LOL Kudos man can't wait for the fall video!
I remember watching you years ago as a little boy lmao. Great to see your still getting at it.
I really like the final iteration and I really want to build one but I'm wondering if a double rudder design on the back may help with turning or if it'll throw the vehicle out of ground effect?
Could you apply a ceramic coating to the camera lens to help water run off? Even some Rain X could work.
My favorite channel. Congrats
I'm curious if there would be any difference if you essentially duplicated the main body wedge behind the existing one with a gap between them and connected by horizontal stabilizer wings on the side in order to make room for the aileron to guide air from the front wedge to the rear wedge to stabilize the porpoising and shift the center of mass overall so the rotors cant forcefully drag the vehicle out of ground effect into the air.
