RC Car to Ground Effect Vehicle Conversion

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.

[@TedLJones]

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.

[@buckstarchaser2376]

"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.

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.

[@insAneTunA]

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.

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.

[@jackmclane1826]

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.

[@oisiaa]

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.

[@oadka]

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

[@oisiaa]

@@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.

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!

[@AerialWaviator]

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.

[@TheScottsawesomeart]

[@emanuelevilla7504]

why don't you flip the wings in order to have extra downforce?

[@Bbbbillythekid]

Did you made a rudder or aileron to control it?

[@TedBackus]

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

[@ghostbombl8034]

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?

[@ToWhom]

Maybe I’m confused and I’m new to your channel but in f1 ground effect is used to refer to creating downforce from the underside of the car, sucking the car down to the floor so to see the car taking off was the opposite of what I expected.

[@elijahf111]

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

[@pauljs75]

Wing twist and drooped tips are things you've done with prior related projects that looked like they worked, why not carry those over? (Difficult to do with construction techniques demonstrated?) Also the lack of rudder on a ground effect vehicle seems like a glaring oversight. Although it still seems fun to mess with. Also the hydroplane sneak-peek looks pretty kick ass. If it planes up as expected, it's gonna haul.

[@112lucario]

That sneek Peak image looked sick

[@CaptainHoratioPugwash]

Yeah, looked like something you might build to set/break an RC land-speed record.

[@StealthTheUnknown]

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.

[@SKAvius.]

I think you need V shape tail or wings for stability and for a straight flight like "Caspian sea monster" first version.

[@aljensen7779]

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!

[@RoyalStoner]

Dude. This is amazing 💯👋 🤩

[@HardAxe]

why do you need ailerons? two servos in tail would be sufficient and easier to build. Also weight adds takeoff speed. do you really need to add glass-fiber? It is stronger, but then it crashes faster.

[@patrickradcliffe3837]

you need side plates on the wings to hold the air under the wings, another option is anhedral on the front wing.

[@nebula_wolf3132]

that altitude response seemed a little aggressive, and id suggest putting the edf in front of the wings blowing a bit under them, like in the original ekranoplan designs, and some of your own ground effect vehicles. also i think because of the scale of this model, the optimal altitude would've been where the wheels would still be touching the ground, so you wouldnt really get the efficiency boost from flying low.

[@JaydenLawson]

Fun. Why didn’t you make the wings wider?

[@bismuth7730]

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

[@robohippy]

Hmm, only 2 kinds of RC vehicles, those that have crashed and those that are going to crash.... Flew a hang glider for years, but a long time ago. My understanding of ground effect was that when low to the ground, the air pressure under the wing was greater than the pressure on top of the wing, so you would glide farther/your glide ration was longer, with ground effect than whey you were up in the air. Looks like the flying one at first had an upside down air foil, with the camber on the bottom side of the wing. As for flying wings, they do have a bit of reflex in them for pitch stability, but I seem to remember that it was accomplished with wing twist/warping, so angle of attack near the fuselage was lower, and angle of attack at the wing tip was 10 or so degrees higher/more positive. There was one flying wing, can't remember the name, Sundance maybe, with very high wing camber/foil thickness and that reflex all along the trailing edge, along with the wing twist. High lift, slow speed, and very difficult to stall. Looks like you are having fun. Trying to remember, but isn't ground effect also linked to wing span? As in longer wing span/higher aspect ratio = better ground effect and also ground effect comes into play higher off the ground than short aspect ratio.

[@mavisowens7950]

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

[@elpelon10501]

Can you do a ground effect under the chassis I will like to see what design you are goin to try !!

[@Mr.Unacceptable]

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?

[@bradleyj.fortner2203]

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.

[@phillusderpimmelpilz871]

Would be interesting how much downforce a rc car can take or how this effects the car. Maybe u reach a point of proposing or what its called in this years f1 cars where they have so much downforce that the airstream under the car breaks for few secons and the car starts wobbling like crazy. Sorry for my english

[@chrisoneill5599]

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

[@FiltyIncognito]

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.

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

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?
