"..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 like this ground effect series. Make more!
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 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!
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.
The sneak peak was a great idea. That fuselage looks amazing.
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.
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 🤣
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
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.
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
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!
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.
Loving these videos, manage to make even the smallest details interesting.
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
Love all of these videos, please continue doing the autonomous boats!
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.
I had one of those cars, drove it into the ground for like three years, it’s a beast
Another amazing invention and video. You are the most entertaining tech youtuber out there. Keep up the great work.
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)
Keep working on this! You're working on my dream project!!!! Awesome job!
This is exactly what I needed this morning.
That's a win in my book. Extremely interesting content and butter smooth. Subbed
Great video! Amazing to see you bringing your ideas to life!
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?
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.
Any day a new rctestflight video comes out is a good day
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
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
Excited to see the speed racer!
Pretty cool! Still one of the better RC car airplane conversions I’ve seen on TH-cam even though it didn’t perform like you wanted! So awesome!
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 ❤❤
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.
This is my favorite TH-cam channel, what I want to be able to do!
The funfetti can was awesome!
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
"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.
your sneek peek looks cool
LOVE YOUR CREATIONS MATE!
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...
You got to try out those techniques and you learned a ton so i would say this was a humongous win.
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
that was sick dude
Knowledgeable guy. He’s an aeronautical, software, and electrical engineer.
Congratulations to 420k subscribers.
Nice
Very cool project!! Mad scientist of flight!
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.
*@**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.*
That sneek Peak image looked sick
Yeah, looked like something you might build to set/break an RC land-speed record.
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!
Very cool. Those WL cars are popular around the world. All kinds of crazy upgrades and speeds.
Hey, its not an ad, but for RC things you can print with Filamentarno Aerotech filament, so project will be super light
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.
oh boy new 4am upload to watch
Sneak peak is dope
the build lquality is magnificent.
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.
Yours must be the coolest house on the block. As ever outstanding content
Great wings..... Want to see some more of them!
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
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.
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?
Your voice is deep and satisfying
I gotta know who drives the Miata, that's CLEAN!
3 videos in a month dayum!
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.
You just keep amazing, BIG LIKE
Awesome work man bravo 👍👍
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 should try to connect the front drive with a propeler and activate it as soon as you lift off and propeler doesnt hit the ground. keep it horisontal while you drive. probably brakes it after landing but it would be a cool video
That rc car video was amazing do more like that 👏
I’m liking the fun fetti epoxy mixing cup
I admire this kind of people!!
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
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.
you need side plates on the wings to hold the air under the wings, another option is anhedral on the front wing.
That looked really effective actually.... 😎
woah that sneek peek!
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!
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?
cool velo shot!
Your voice is soothing
I like the sneek peek Bro... ;)
Sick sneak peek
What's the sand paper that you used?
Love the Jerry Baker Memorial Velodrome cameo!
*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
Wow. Are you a magician!
That ekranoplane looking plane is cool in start
I like sneak peeks :-) nice vid. Thx
Dude. This is amazing 💯👋 🤩
Love the rc car vids keep it up
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)
you should build a decent sized boat that uses a mini RC 2-stroke combustion engine and carries a good amount of fuel. though you need to remember good cooling cause long running time. i know it would be very inefficient but i think that some short waypoint missions would be possible also it would surely be pretty cool!
