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 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.
The Delta is actually a very stable airplane. Listen to the wind noise in the vid... any airplane is going to be tossed around with wind like that, no matter what configuration it's in. The big fat wing gives it very gentle stalls, too, with no tendency to do flip-flops like some delta wing aircraft. With a whopping 50hp, the thing scoots along with a VNE of 270k[h (167 mph) and stalls at 85 kph (52mph). It's actually a very nice airplane with a good safety record. It's also rated at +/-6 g. But yes, some RC planes do have a larger wingspan! They also have a 2 seater. Cheers, jc
@@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.
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) 🤝

@@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

The way it constantly rocks in flight shows me that the design of the Aircraft makes it a task to fly and and maintain stability! It fly's like a "crash waiting to happen!"
Interesting plane and many thanks for doing this in 4K! It allowed me to do testing with a regular monitor and BOY, IS THE PICTURE MORE DETAILS - and THIS IS NOT A HD MONITOR!!! But it sure looks like it on your clip!!!!! MANY THANKS!!!!
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
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.
I saw one of thsse if not this one fly over in Buckinghamshire this year it had a Censna following it weired to see, such a distinctive shape in the air.
Looks like a UFO from a distance. I'm sure the prop noise kinda gives it away though. Love it and appreciate what went into building the craft. And that engine purrs like a kitten. 10,000 thumbs up.
@@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
Many compliments for the original but functional aircraft !!! the pilot has courage to sell! !! who built the plane really has a lot of brain ☺☺☺☺☺👍👍👍👍👍
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.
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?
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. ruclips.net/video/rQNPl5DdS5I/видео.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. ruclips.net/video/BNQJRIwKzTE/видео.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.
I’m no aircraft buff, but I seem to remember way back in the 1950’s “yes that long ago “ The Americans had a huge nuclear strike bomber called the flying wing of almost identical design. I watched with awe film of this marvel wondering in my childlike way how the hell it could fly. Anyone else remember this?

If a Reliant Robin became a plane- it would look like this.
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.
It's great to see someone fulfilling their childhood dream of flying a lawn dart...
hahahaha, good one...I'll be chuckling about this for the rest of the day, oh man, ya, hahaha

I doubt the manual has that many pages unless the disclaimer is located there.
Extraordinary, so comfy sat here in front of my computer.

"Just an engine and possibly a tail section."
"Well then bag it up, let's go, I've got flying to do!"
Old lawnmower engine.
Why do I feel like there are several ways to easily get this aircraft in to uncontrollable and unrecoverable scenarios?
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.

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.
Beautiful little mothwing. Love it!
The delta wing is very structurally efficient. Extremely cool too.
It looks a little " tender" in flight, like wobbly as if there were too much control surface & stability is on a knife edge? Looks cool, sounds great
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.
All I can say is, "No, thank you!".
I'm amazed this little plane had enough lift to get this guy's GIANT Balls off the ground...
it let me think on a folded paper aircraft
What a beautiful piece of aviation art in motion
Looks like an accident waiting to happen.
reason why landing part is cut off
That is EXACTLY what I was going to post! So true.

Inferalanding, of course you do.
Thank you for posting. Very interesting.
Talk about "A wing and a prayer" that looks sketchy, as fuck.
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.....

Watched it fly overhead a couple of years ago flanked by what looked like a couple of RV's . Jaw dropping
It looks like "Independence day" spacecrafts

The wings look like they are walking a tightrope, looks very unstable and difficult to keep in level flight, but it does look like a lot of fun.
This one and the Greek Archon are two great homebuilts.
Love it! Hmm ... I can imagine a 2 (or 3) seat variant with bigger engine and wingtip tanks ... it could be a snappy cross-country fun machine.
The reverse dihedral makes it look really unstable.
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

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.
The USAF back in the 50s experimented with nearly identical full size deltas. Apparently they flew rater well.
its fly.. thats enough 👍🏻 enjoy it

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