"..I bought a cheap Rc car.." "..don't break that, it was expensive!"

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.

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".

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 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.

The sneak peek is beautiful! And I really love the idea of having wheels on a plane. This was such a cool video!!

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.

That brushed motor is insane, I've never seen a brushed motor that sounds like that or has that kind of power

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.

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.

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!

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

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.

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.

Pretty cool! Still one of the better RC car airplane conversions I’ve seen on KZfaq even though it didn’t perform like you wanted! So awesome!

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.

"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.

Knowledgeable guy. He’s an aeronautical, software, and electrical engineer.

I had one of those cars, drove it into the ground for like three years, it’s a beast

I love all your projects that work great but I think including the ones that don’t is what makes the channel really great.

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.

That sneek Peak image looked sick

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.

Any day a new rctestflight video comes out is a good day

Another amazing invention and video. You are the most entertaining tech youtuber out there. Keep up the great work.

This is my favorite KZfaq channel, what I want to be able to do!

I gotta know who drives the Miata, that's CLEAN!

When I get an inline ad like this I list it and skip past it and make sure I DON'T buy off of that list. Hey, I"m doing my part.

*@**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.*

Now a word from Blinkist.. "I love books and podcasts, but sometimes I have a tough time fitting them into my busy schedule. I'm totally not reading from a script, and you can totally not tell from the way I'm speaking."

your sneek peek looks cool

the amount of work you put into this...the rc car was literally the cheapest part

That ekranoplane looking plane is cool in start

“Don’t break it it was expensive” “ do you think it can drift?”

The funfetti can was awesome!

The sneak peak was a great idea. That fuselage looks amazing.

"I bought a cheap 1:14th scale buggy" A few seconds later "Don't break it, it was expensive"

You got to try out those techniques and you learned a ton so i would say this was a humongous win.

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.

"Bought a cheap one" 10 sec later "Jesus, dont break that it was expensive"

Love the Jerry Baker Memorial Velodrome cameo!

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.

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.

Love all of these videos, please continue doing the autonomous boats!

oh boy new 4am upload to watch

Super cool, the whole time I was thinking of dodo flying cars from GTA.

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.

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.

Congratulations to 420k subscribers. Nice

I feel like this guy has a whole year worth of monthly uploads just implementing some decent developmental improvements. Like even on the solar plane v4 realistically.

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

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.

Very cool. Those WL cars are popular around the world. All kinds of crazy upgrades and speeds.

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.

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!

In an age of brushless motors, People often underestimate how much power a brushed motor can have…. Somewhere I’ve got an old car that I put a Kyosho Magnetic Mayhem motor in and it was an absolute beast with the right gearing and a 3s lipo. I think a lot of the stigma of brushed motors being underwhelming has a lot to do with the pre-lipo batteries of the day. Make no mistake, brushless is better, but a good brushed setup can still be a blast. Even the cheap, venerable Titan 550 12T will will ballon tires right off the rims.

Excited to see the speed racer!

The wltoys 14001 is a awesome very budget friendly entry into hobby rc with out breaking the bank goes as fast & built better than most 300 entry cars & cost less than half the price!

Was interesting to see a Ground Effect car that isn’t the usual type of Ground Effect lol, great video

Bro...... You're the modern day Da Vinci!!!

Wing tips, downwards, to seal the airflow beneath the wing and the ground. This isn’t flying in ground effect, just close to the ground. Ground effects require a seal with the ground or water to be… effective

This is exactly what I needed this morning.

Your voice is deep and satisfying

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.

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

Hey, its not an ad, but for RC things you can print with Filamentarno Aerotech filament, so project will be super light

“Bought a cheap RC CAR” then next scene… “ don’t break that it was expensive”

The car he used is the WLToys 144001... one of the best budget buggies; a clone of the LC Racing chassis. They a truggy 144002 and a the brushless of the same chassis 144010. They also versions that have a slightly longer chassis; 124018/124019 with a brushed motor and brushless as 124016/124017.

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!

"So I bought a cheap 1:14 scale buggy [...] on the internet" slightly later, someone else driving it: "Jesus don't break that, it was expensive!"

"...so I bought a cheap 1/14 scale buggy..." and in the next clip: "Don't break that, it was expensive..." :D

I’m liking the fun fetti epoxy mixing cup

The EDF also doesn't respond as fast which might affect handling a big deal

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.

This guy is so wholesome

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's a win in my book. Extremely interesting content and butter smooth. Subbed

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.

3 videos in a month dayum!

more angle is very important I think bc. you want maximum direction of air into the ground vs. the regular lift of an airplane. I think this is the reason it just started flying.

Takes me back to the time you put a duct fan on the new bright ferrari and you guys screwing around at Walmart 😂 good times 💯

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.

Omg that teaser made me ....

this guy be making rocket derby real

I think your friend may have been wreaking havoc, too.

Why not nest some wheels into the wing tips and tail section, and just use the prop for forward drive and only some small servo's for turning the wheels? It'd save you a ton of space and weight. Also, it would be worthwhile to use some wheels with much less friction. When you're about to take off or land you don't want the wheels suddenly pulling in a different direction than its current momentum, especially when only one or two wheels are currently in contact with the ground. That's a good way to suddenly swerve, spin or flip it into a crash. You only need sufficient friction to turn the GEV at speeds that won't tip it over.

That looked really effective actually.... 😎

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?

Yours must be the coolest house on the block. As ever outstanding content

Loving these videos, manage to make even the smallest details interesting.

You know, I've always wanted to see someone go nuts with edf fans and blown flaps/boundary layer control. There was a c-130 stol version that never went into production that had two jet engines outboard of the turboprops. Bleed air from the jets was blown over the flaps and rudder to enhance lift and controllability.

"I bought a cheap rc car online", "don't break that it is expensive"

Your voice is soothing

LOVE YOUR CREATIONS MATE!

"I bought a cheap RC car". Next sentence, "don't brake it was expensive" ... lololol

6:46 when you type come fly with me on GTA VICE CITY

There's a thing about sailing and flying. If you're sailing, sail. If you're flying, fly. Make something that will fly, then start cutting.
