hahahaha, good one...I'll be chuckling about this for the rest of the day, oh man, ya, hahaha

La taille des arbres fruitiers

I thought the 737MAX's were the lawn darts:(

Jart!

@MichaelKingsfordGray Well, that escalated quickly.

Didn’t they do that on TopGear? It kind of did look like this. They made it like the Space Shuttle LOL.

Then it could be called a Flying pig Vs Plastic Pig !

I thought it was a reliant robin 🤣

Yeah, but if the plane could perform a roll it would actually look cool.

The Robin is a poor performing driver while this has actually pretty decent flight characteristics for a homebuilt aircraft.

Seems unstable doesn't it? Maybe pilot is not experienced/skilled?

It's supper windy you can hear and see it in the beginning of the video

I wonder if the anhedral causes that. In this plane according to Bert you have to pick up a wing in the steal with aileron, not rudder. First makes it spin.

@@myotherusername9224 Something appears to have been 'lost in translation': 'in the steal with aileron'.

@@myotherusername9224 Yes, I was thinking if he'd built it with some dihedral it would have made it more stable than it is. Maybe later. Clever engineering, though. Good luck to him.

Absolute BOOM! I just came here to say the exact same thing, with a little tweaking of the design, and perhaps replace the motor with a turbine or two, it could come closer to looking like one, I think air display patrons would go nuts for it (not that they wouldn't/don't already, it's a cool and quirky little machine) 🤝

I have GOT to get me one of these!

the fact that it sounds like it has a 700 cc honda shadow engine in it?

because you're not a confident, licensed pilot perhaps?

No he’s right. Likely unrecoverable in a spin. And it looks twitchy as hell.

because there are.

@@matycee lol what? Even a confident, licensed pilot would agree with this statement. Thats is "experimental". Don't speak for pilots when you clearly aren't one.

it let me think on a folded paper aircraft

Thanks for watching

And we all know the fate of the flying wing...

​@@zulu0219 Yeah, it grew into the B-2.

Old lawnmower engine.

reason why landing part is cut off

That is EXACTLY what I was going to post! So true.

No shit! Damn thing is bouncing around big time!

My thought exactly.

@@ankushzap there was no "landing part", it's not able to land safely, it's still flying

167 mph??!! Unbelievable.

Those are some decent specs for that airframe.

Like UFO!

@@ayokay123 167 mph is its Vne speed. (maximum airspeed before it is unsafe to go any faster in stable air) any plane that flies can nose toward the ground and reach a maximum speed. It's the cruise speed that is what really matters when you're trying to go somewhere.

Excellent comment

With enough power and speed anything can fly.

Least you know itd be reliable with an ea71. The subaru ea series engine with ohv are bulletproof.

It is obviously unstable. Wings rock back and forth. So does a Cessna and virtually all similar airplanes, but not as much as this delta wing example.

wonderful looking coffin.....

are you reading my mind?)

Man I haven't been able to post da F word for years. How you getting away with it?

@@Bocbo It is so fucking easy, just try!

Sounds like a Model A.

More than one, from what I've read.

ugh

Hahahaa I thought the same

Rodrigo Ruff

Hahaha true story

XD

I doubt the manual has that many pages unless the disclaimer is located there.

Yep, that's exactly the right word.

Kind of like trying to balance a marble on a pice of plywood.

I was thinking the same thing... one fart and she's in a flat spin.

It naturally wants to be upside down with that reverse dihedral. Someone’s going to die in that plane.

It needs fly-by-wire computer control.

It isn't.

This Video was taken two days before the airshow , it must leave to another airport ,that is why you don't see the landing .To please me he made a few runs over the airport .More info of the designer you can find Here www.verheesengineering.com/

I was thinking the same. Looks like it would be very tricky considering there's such little clearance between the wing tips, the tail, and the ground. Cool plane though.

Wasn't one !

Probably couldn't show the crash landing. First and Last flight for little crash test.

Well spotted. Obvious DNA from both.

I'd have to say a flat stone. The cavemen discovered if you throw them across water at a high rate of speed they'll almost fly.

You mean like a Mig?

Inferalanding, of course you do.

Benjamin Stephens tell us more about why delta wing instability is going to result in a crash? Thank you for warning us with your knowledge.

Put a sock in it you "expert"

It's got a ton of anhedral. Probably makes it responsive but crazy twitchy. Not for me.

@@KingDadNC to bad there is no way to set it up with a gyro like the use for rc planes, aileron, elevator and rudder controls run through the gyro and it counteracts unstable air so flying in the wind is not an issue

@@blackbirdxx928 With a strong enough gyroscope, it could even keep the landing gear with only two wheels and replace the tiny wheels in each wing with a small rubber shield.

It looks like an ME 163. Very curious, but it seems to have really poor pilot visibility. You can only see up and forward.

@@56squadron Actually it looks a lot like a Lippisch P.13A or it's predecessor, the Lippisch DM-1 which were German "all wing" delta aircraft that was experimented with during WW2

you are absolutely right Cruise speed 220 km/h or 120 Nmiles/hour and uses only 13l/hour or 3.45 gal/hour Read more on :www.verheesengineering.com/gb/delta.html

It doesn't need to be stealth. It's so small nothing can hit it.

Don't say that out loud.... GCHQ and the RAF might be listening!

Do you mean anhedral?

It looks kind of not very stable

It seems noticeable, a little shaky in roll. I thought it was a brilliant design though.

i think the huge vertical stabilizer compensates the anhedral. www.merriam-webster.com/dictionary/anhedral

I think the anhedral is an illusion. When looking at it from the front, it's at a positive angle of attack, making the swept leading edge appear to slant down. Similarly, when looking at the rear, the center nonmoving part of the trailing edge is also swept back, making IT look like it slants down. But if you look at the rear of the straight flaperons, they look straight across. I'm not 100% sure, but I can't think of any good reason to have used anhedral in the wing. Also, in the very rare head-on shots, it's completely flat.

It does to look twitchy in flight , a strong gust may flip it in air , but I'm not into turning myself into freefall !

They are actually elevons

that engine is probably pretty small. the sound you're hearing is the prop

It's a converted automotive flat-4

good one

Yes, the one that was going to burn coal! I thought that too.

As usually happens with makers of such planes, he tried his hardest to make it tail-less, then went with wing-tip fins, and finally the best versions became tractor prop with a fin right in the prop blast. Canova, Cheranovsky, Fauvel, Arup and others went the same route, eventually dispensing with tail-less and all putting a fin on it and solving all problems. Lippisch made several long swept-wing deltas and then some short aspect ratio. Most famous is p-13a , and partially completed test glider, which was captured and became much-studied -by Vought and Convair especially. kzfaq.info/get/bejne/qLd-g89mqcq3ZX0.html See Lippisch Delta-IVc(DFS-39c) Then Messerschmitt put a rocket into the eventual longer-wing development for the Me-163 which he worked on while others built the little DM-1 glider. The little propeller planes looked nice, and all scooted along on tiny engines like this or as small as 30hp for 90mph in his Delta-1. kzfaq.info/get/bejne/eLSBfbV63LHehHk.html Note the one moment where it seems to fall sideways while in a steeply-banked turn. The center tailfin/rudder and tractor prop cures that kind of problem on a plane with no fuselage or tail-less planes. It's sometimes called brushless, when it has a fin but no separate tailplane. The Arup was quick and nimble and better-behaved than anything we see today, simple cheap and rugged, ignored by the markets like these other tail-less, lifting body, or all-wing planes. Sush designs are starting to make a come-back due to fuel economy awareness, as well as making designs which are smaller and more prone to being stealthy.

German engineering ! Salute !

which concept was copied from a french design (they had the engineer, Mr Payen, working for them during the war)

It looks somewhat like a Horton prototype.

Very very longitud distance

These are small, those are far away

Schizophrenia on a plane!

Wind = Turbulence.

probably worse then a Piper TriPacer lol

I'm thinking rock.

That was my first thought when it flew.

i'm not a pilot, but I do know that the smaller the plane the less stable it is.

I kinda noticed the same similarity.

Rite on brother , you said it all .

Compared to the Nigerians I'd say this is like star wars. I bet anyone can fly it.

It's a very stable and well performing machine, as war as home-builds go.

Nah, you'd be mental to try flying a T-16 through there with those mods... Where's the dorsal stabilizer? You'd corner right into the rock face.

Just don't try to beat the Kessel Run in 12 parsecs.

I prefer an Electric Grill in my Hot Tub...

It is a flying wing

I way trip to the afterlife

Look at the wind blowing in the trees behind the first camera angle as the pilot was boarding. The wind is at least 10 knots maybe more.

It’s kind of ugly, but clever in so many ways. Such as low drag landing gear requiring only the nose gear to actually retract. The craft is low to the ground, but high in the front for propeller clearance, and they takeoff roll is at high angle of attack, ideal for a short field type scenario. The cockpit and the vertical stabilizer are part of a single aerodynamic unit. I think it works like an F106, what are used to work on when I was a young man, where the Delta wing trailing edge, the ailerons and horizontal stabilizer are combined. I think he could really have something refining it to a much higher aspect ratio wing, and a wing not so fat. I mean I really admire what has been done here. Truly remarkable. Great to see it fly, a little wobbly, but looks like so fun to fly.

Indeed very clever , you are someone with knowledge of Aerodynamics and planes

I wonder what Vsi and Vm are and how much separation there is between the two.

Maintaining control even in the stillest weather looks challenging… but I imagine equipping it with a parachute wouldn’t be too difficult. It‘d be of no help during takeoff or landing, but I’d still buy two if I knew I could push a big red “PARACHUTE” button during a higher altitude emergency. It looks like a rollicking good fun airplane to fly! Any idea if the inventor has plans to bring it to market?

Very-quickly, I'd imagine...

Larger engine and some wing dihedral for stability.

50 hp is enough for its 450~ lb

Its unsteadiness does indeed have that effect.
