"..I bought a cheap Rc car.." "..don't break that, it was expensive!"
I mean, it's relative.
For example, I don't think many would consider a 'cheap' private jet to be a disposable toy.
Bro at first decide what u wanna say cheap or expensive
If the cheapest rc car is 200 ...its still expensive
@@alsigamerr9939 bro first understand what relativity means
@@niklask1651 that's where relativity comes in, in the rc hobby 80$ rc car is considered cheap compared their 400$+ standard rc cars.
Looks like the problem is most youtbers trying to make ground-effect vehicles only use speed to generate lift. The original machines used engines to blow air under the wings for huge lift at low speeds, then use rear engines when specific speed and lift are reached.
Maybe you could use an internal duct system to pull air from above the vehicle and redirect it under the wings and backwards, if only for takeoff/landing/low speed travel.
Also, remodel the wings to maintain the high-pressure air bubble. It's losing pressure meaning you need higher speeds to maintain the necessary pressure.
"maintain the high-pressure air bubble" like an engine bell from a rocket?
Sounds legit. I think that's how hovercrafts work, so it should do something, even if that relegates it to an even-lower flight envelope. It looked like he had the basis of that in mind when he made a sort of bowl over his RC car, but then seemed to forget what his plans were when he put the ducted fan way in the back, screwing up his CG and counteracting his "flying aerofoil tail" concept by blowing high-V/low-P air under it.

Who do you think you are these days? I don't even recognize you anymore.
Dude! Years from now, when you're a famous aeronautical designer, students will watch these vids and see your engineering journey. Keep up the great work.
You could use the leftover car parts to do a ground effect car, just the other kind that used to be used in F!. Perhaps even a Gordon Murry style "fan-car".
Seconded!
This was what I though of when I read the title. Btw, they are using ground effect/venturi tunnels in F1 now as well. Not fans though, just the venturi-tunnels ;D
This is what I had in mind before I watched the vid.
whats going on in that house???

The sneak peek is beautiful! And I really love the idea of having wheels on a plane. This was such a cool video!!
I don't like rctestflight videos under 15 minutes long. I get so into them that it sucks when they end. You're such a tease!
Yeah, if you've ever done a cheap "lost foam" mold, using packing tape around your plug is a good way to do it since the resin doesn't stick.
I like this ground effect series. Make more!
I love the ground effect idea. More please! Your videos are great, and you're a great innovator... the world moves forward by the work of people like you.
I love all your projects that work great but I think including the ones that don’t is what makes the channel really great.
It reminds me a bit of this RC model called the Hydrofoam, the underside is shaped like a catamaran, and it can drive over water, it can fly, and it can drive over grass. And you are right, it has some hovercraft like features. Basically the single wing spans across the entire length of the aircraft, with a big rear wing that spans across the entire width of the aircraft.
#Hitydesign
I used to work for a very large fancy yatch company and your fabrication is very similar for this project. I look forward to what else you're gonna do.
The sneak peak was a great idea. That fuselage looks amazing.
I love your projects! Would like to see a very large multi-engine (EDF) with sailplane style wings and several hours of endurance for a ultra-long range cross country flight.
The words EDF and sailplane, endurance should not be used in the same sentence.
Jokes aside, EDF's have poor efficiency. (the ready made EDF's available on the market)
Custom made EDF's have scope to be efficient
@@oadka Oh, I know. I was thinking something like a heavy lift glider that can carry a big 20kG payload. So a lot of thrust from EDF on efficient wings to carry a big payload.
#Hitydesign
Another amazing invention and video. You are the most entertaining tech youtuber out there. Keep up the great work.
This is a great video. Please don't give up on this idea it's great to see content like this thank you from New Zealand.
That brushed motor is insane, I've never seen a brushed motor that sounds like that or has that kind of power
They are freaky, I had a 1:10 scale Nissan that was using a brushed motor and it went like a rocket 🤣
Loving these videos, manage to make even the smallest details interesting.
The main body addition is basically a large cup doing little in my mind other than slowing it down. Some plastic wrap over the front to smooth out air flow and stop the cupping of air may help.
A symmetrical airfoil does still generate lift. And the horizontal stabilizer is also used on a conventional aircraft to generate either lift or downforce in order to keep the moment balanced in cruise. Cool project!
Great video! Amazing to see you bringing your ideas to life!
Love all of these videos, please continue doing the autonomous boats!
That's a win in my book. Extremely interesting content and butter smooth. Subbed
The height of ground effect (without skirts or similar) depends on the wingspan. Half a wing span is the rule of thumb there and it almost instantly vanishes when you exceed that height. So... model ground effect planes a a notorious pain in the rear.
When the plane gets big it also becomes very stable.
Keep working on this! You're working on my dream project!!!! Awesome job!
I think putting the fan on the front of the vehicle could be a great thing, the CG in front the EDF pushing the nose down
Pretty cool! Still one of the better RC car airplane conversions I’ve seen on UA-cam even though it didn’t perform like you wanted! So awesome!
I don't know how I stumbled upon this but this is amazing to watch.
(and it was trippy to see the mm velodrome in a random vid)
Neat! I made a wing out of a piece of similar insulation I found by the road and used it in a glider I made for my 6yo son, using free stuff means he can break it and my head doesn't explode. I had no idea it was something anyone who knows what they are doing would do. I covered it in high fiber content house cladding paper, it has a slick surface that is great for similar uses.
I had one of those cars, drove it into the ground for like three years, it’s a beast
I was looking to design a ground effect vehicle years ago and came across some rules of thumb from a dude who made a personal watercraft sized one. The rules of drag change a lot in this regime and the craft he built had the chord length be the length of vehicle, and longer than the span. Making it so the vehicle can't fly out of ground effect.
What was his craft called?
Awesome build, I'd love to see how you designed the CAD for the aerodynamic surfaces, and how you determined where the CG would be. I hope this is something you consider for a future plane build
football fields, or even a tennis court or any place with outdoor bleachers & a long flat surface are great places to run R/C. the elevated PoV bleachers give is great , and the long flat surface allows you to have room to run.also mall parking lots during off hours or holidays
I enjoy your attempt here - I especially like how you experimented with different wing lifting aspects: i.e. the conflict between Bernoulli and Coanda. Good try - A+ for effort.
Congratulations to 420k subscribers.
Nice
Very cool. Those WL cars are popular around the world. All kinds of crazy upgrades and speeds.
Yours must be the coolest house on the block. As ever outstanding content
I saw your sneak peek at the end, Daniel. It looks like you & I may be bucking for a marine speed record this summer. I'm currently building a hydroplane & expecting to exceed 100mph with two counter rotating EDFs. See you on the water!
LOVE YOUR CREATIONS MATE!
Any day a new rctestflight video comes out is a good day
This is a big improvement on the last design. I feel like you're almost there! Please don't give up. Refine the design and retry =D
I just spent the better part of 4 hours on my Saturday morning watching your channel. I might be grown up but damn I wanna go get some RC stuff today.
That's how I started, 9 years ago. Suggest you to watch his really old videos building crappy planes with rudimentary materials, they were even better IMHO. It made me copy several of his designs. Nowadays he's working with cutting edge techniques and materials, I can't keep up
@@hotpot321 Dude I've been watching all his stuff from 12 years ago! Can't look away
This is exactly what I needed this morning.
*@**7:11** "It certainly didn't fly well" is a relative statement. I've seen some finished projects that weren't that stable lol.*
*Your expertise likely surpasses mine but I wonder if you could design a ground effect wing chord that dumps lift past a certain angle of attack.*
Can we all take a moment to appreciate the work this man is doing to entertain and educate us with his amazing videos? Man thank you very much.
It's pretty sad that you keep posting " can we all take a moment to..." on popular videos just so that you get likes.
We all appreciate his videos, why else would we watch? Stop posting the same copy/ paste comments on multiple videos.
He does it for the income too I would imagine. There are a lot of people who would like to get paid to do their hobbies, doesn’t seem like much of a sacrifice at all.
Can we take a moment to wonder who it was who started this "Can we take a moment..." craze and think about what punishment would be fitting? Ostracism? Withdrawal of pizza rights?
He was probably one of those happy-clappy religious types i see in American films that stops the flow of people having a good time by asking the group to thank his invisible friend for the good time he just stopped!
Please, no more Americans saying ""Can we take a moment..."!
#Hitydesign USA today
Was interesting to see a Ground Effect car that isn’t the usual type of Ground Effect lol, great video
Bravo Sir! That is an epic conversion ❤❤
That sneak peak reminds me of a ground hovercraft I made out of scrap foam and electronics. It worked SOOOO well lol I need to find that super old vid and post it.
This is a brilliant idea. Great job, I can’t think of anything that’s wrong about it but I’m sure someone will see something, just remember that any imperfection, IS a perfection.
Everything can always be made better...Yes was but need something to make it turn.N a propeller n front to stay n the air...
this would be super fun to fly over a large flat area like a relatively open flat desert. it would also be useful in said areas where - as there is no road access.
"blinkist - I like to let other people think for me and tell me what I think instead of thinking"
Keep goose steppin friend. Your fuhrer will thank you.
Very cool project!! Mad scientist of flight!
I began with big expectations, but I have to tame my imagination and take time to learn the basics. I enjoy watching your videos and the technology-style that you use. My ultimate goal is to build a uav that will travel a few hundred miles. i have a long way to go. I have been spending more time with my 3d printer, as of late. Sometimes I have to take a step back due to frustration.
I have watched many of your videos, more than once, and have seen some great ideas to incorporate into my design, specifically the breakdown of demonstrating each tech. that I would like to incorporate, (logistics). For instance... I would like to incorporate solar panels in the wings to recharge the starter cells for the onboard starter. Lets not forget about redundancy by having the ability to utilize a second set of control features, including an electric motor.
I am putting a rudimentary plan for a large scale model that incorporates, 'wet-wings', by building fuel tanks into the wings. I am looking into 2-stroke, 4-stroke, gasoline, fuel/oil mixes, etc. Also, I have t look into a ground station and other ways to communicate with the drone, like WI-Fi. i am unsure, but I have thought about providing the drone with its own hotspot. From my understanding, is I keep my drone under 2,000 ft., I can receive a WI-Fi signal. again... Redundancy. Because I could lose communication/data link.
I would gratefully appreciate any and all input.
The problem with this is also one of stability. You need a geometry that has a speed-dependent lift coefficient, and one that doesn’t tend to generate extra lift at high angles of attack. Delta wings are good for this and can provide good yaw stability as well. This thing wants to pitch up and yaw around because it’s wide and has a high deviation in lyft with its orientation. The airfish 8 has a good airfoil shape to follow, I’d give it more taper at the front towards a more diamond ♦️ shape with a wider chevron towards the back, and downward flare to produce a dynamic pressure pocket that dissipates the moment you leave ground effect. It should sit high in that cushion of air, with little aerodynamic lift out of ground effect, but with restoring force that has a forgiving deviation in its inherent aerodynamic shape: it’s JUST passable as a “dart” out of ground-effect, but just under a “glider” in ground effect.
Excited to see the speed racer!
Have you thought of drilling many tiny holes through the table and use a vacuum pump to keep the foam piece secure to help with the process?
That much success on a first try seems pretty good to me. I'm confident that with a few tweaks here and there you'll get it to do what you want.
Wouldn't playing with weight and balance keep it in the ground effect zone? Only using the angle of the wing to create enough lift? Could you have made rudders that worked off the same servo as the steering? Or the same signal?
You got to try out those techniques and you learned a ton so i would say this was a humongous win.
Awesome work man bravo 👍👍
This is my favorite UA-cam channel, what I want to be able to do!
Great wings..... Want to see some more of them!
That sneek Peak image looked sick
Yeah, looked like something you might build to set/break an RC land-speed record.
I'd call a flying car a win, even though it effectively wasn't a ground effect vehicle. Utilizing boundary air alone is a complicated process that most people won't grasp the difficulty of. You've done well overall in your vids.
your sneek peek looks cool
The cross-section shape of your wing is perfect... for creating lift. Turn the wing upside-down. Find images of NACA airfoil shapes. Make on of those... but mount it upside-down.
The funfetti can was awesome!
Remember way back when you did a heavy lift aircraft? You loaded it with bolts until it wouldn't take off, I'd love to see you revisit that idea. May have a set power plant, and see how different airframes compete?
That ekranoplane looking plane is cool in start
that was sick dude
Knowledgeable guy. He’s an aeronautical, software, and electrical engineer.
The KM Ekranoplan had thrusters at the front to push air under the wings so it would have a better cushion of high pressure air to float on
@rctextflight where was that track you used at 7:39?
Hey, its not an ad, but for RC things you can print with Filamentarno Aerotech filament, so project will be super light
Just curious why you dont have the main wing tips tipped down to create the air cusion?
I gotta know who drives the Miata, that's CLEAN!
You just keep amazing, BIG LIKE
Can't remember if you have tried using front fitted engines (like 2 on each side to provided more precise power control and have the airflow from the engines blowing over or between the wings, the engine at the back is going to more make it want to fly)
What if you ducted the fan with the intake in the low pressure zone at the front and then route it under the bottom of the back of the wing tip? wouldn't that improve the ground effect?
Sneak peak is dope
I like the sneek peek Bro... ;)
*Hi there, idea for you* ~ i saw a Supersonic plane with ground effect. It looked like a Concord, but with the tips of the wings angled down, called XB-70 Valkyrie. You might get more air pressure that way. All the best
Great video as always! Do you think you could do an ardurover tutorial on how you built your autonomous boats? I’d love to see that
you need side plates on the wings to hold the air under the wings, another option is anhedral on the front wing.
My windchime is strung with 100 pound Kevlar and I thought it would last forever. It lasted three years, only a little better than the 30 pound mono-filament line I put on it originally.
Love the rc car vids keep it up
I like sneak peeks :-) nice vid. Thx
Wondering Daniel, all your Ground Effect Vehicles have used a elevated elevator on the tail. In this RC car based example the elevated tail seem to settle lower to the ground (in ground effect) as the main wing lifts up into ground effect.
You might want to experiment with using a flying canard up front, no control surfaces, just a pivoting canard? This would ensure both wings operating in the higher lift producing ground effect.
Can you guys tell me is a brushed or brushless motor is better I don't know what type of motors are in the three different RC tanks I have so tell me?
That rc car video was amazing do more like that 👏
Are trying fly it or push it to grou?Add little bit more inch to wing s to get bigger lifts with out sacrifice to long wings also.i can see its try lift but not stable.maybe few more inches?
2:17 is that GoPro like on life support?
Or what it looks broken
Did you made a rudder or aileron to control it?
should try 2 edf's up front with duct/fuselage to direct their nozzles under the wings, providing high pressure below the wings while still providing thrust. would give a bunch of lift at lower speeds
the build lquality is magnificent.
oh boy new 4am upload to watch
I’m liking the fun fetti epoxy mixing cup
Hey! Love the video! Is there any updates for the second batch of snowcat kits? I know they are a lot of work, but you mentioned end of winter - early spring.. Thank you!
cool velo shot!
the amount of work you put into this...the rc car was literally the cheapest part
