[@homomorphic]

This is the most beautiful flying thing I've ever seen.

[@pauljs75]

Nicholas Rehm made a similar craft. "Spinning Drone Paradox" covers the functionality of the concept. It traded some efficiency in rotor-craft hovering mode to have the ability to use the blades as a tri-wing for fixed wing flight. The big airfoils are symmetric and change pitch at the hub, which allows the RC craft to both hover slowly and fly in a straight line somewhat quickly. Kind of an interesting project, since it's very closely related in concept to the RC craft of this video but also takes on another way of flying as well.

[@BrightBlueJim]

This is truly an amazing diy project! This is probably the most efficient rotary-wing aircraft ever built, due to the low rotor speed and wing loading.

[@phillipbailey70]

Yes - when I started watching this I assumed that the frame rate made the rotation look slower than it was - the optical illusion you see with some helis, etc. But then I realised it was actually that speed! Amazing video - love it when KZbin randomly recommends something this good!

[@peterrenn6341]

[@useitwice]

Very cool! And its so big! I was truly surprised when you walked into the frame

[@SecondLifeDesigner]

Has anyone else noticed that at certain distances and hover height that you get the same illusion as the silhouette of the spinning ballerina? Meaning the blades can appear to be spinning in the opposite direction and with practice you can see the Levitator spinning counter clockwise and the next second spinning clockwise.

[@marimuthumanoj7206]

It is a kite but I'm not sure, I am trust my science it's fail on this experience on a look

[@KymHammond]

It certainly has an Alexander Calder quality about it, like one of his mobiles. I can’t help feeling that the landing gear needs to be formed like the canopy arms of an umbrella with balls stuck on their ends. So instead of it rocking on that flat crossed wires when it lands the arched bends will help to absorb its kinetic energy as the device comes to a stop on the ground.

[@engineerernest]

[@desotopete]

With some small led lights on the wings that could really freak some people out at night. cool.

[@chrischris8550]

Amazing. I didn't think a singly rotor would be stable. Really great when it slows down and the motion isn't blurred.

[@tymoteuszkazubski2755]

IIRC positive dihedral increases lean back when translating. Theoretically you can control it with one active control surface. If motors were powerful enough you could probably deal with a loss of one or even two motors too.

[@va7drm]

Pretty excited to find this video - I’ve been toying with building something like this over the last year. A few observations - seems like a narrower wing running at higher speed maybe even with the motor mid wing may offer quicker responses. Also, may be some interesting ideas to be gained from the k-max helicopters which use servo tabs. Thanks for sharing your video!

I have been considering a large slow turning system for energy efficiency for a long time. However your antirotation, purpolusion system and control systems are completely different than anything I had visualized. I will be very interested to follow your continued progress. Hopefully it will inspire me to get off my butt and build something again.

[@FilosophicalPharmer]

Gosh, that’s such a beautiful machine! Like a dragonfly pirouette…

[@mkrepps]

I really like the shots where you attached the camera to the root of the airfoil so we could watch the control surface movements throughout the cycle of rotation, but my favorite part was the slow-motion video at the end. You can really study what's happening and even see the flight control inputs are required 90 degrees prior to the motion desired (due to gyroscopic precession). Keep up the great research. I can't wait to see the next iteration! I suggest adjusting the chord to be shorter near the wingtips to reduce the induced drag near the outboard end of the wings. I think this would reduce the power required from the propellers to acquire the same rotational speeds with even longer wings which could have a better lift-to-drag ratio (like the wing tips of a glider).

[@sunspot6502]

[@goliyth5134]

As much as this intrigues me so, one primary question keeps screaming in my head. All of these wonderful tests are being done at what elevation? Given the slow rotation, is this being done close to sea level? I only ask because I walk out my front door and am at 11,000 ft. and helicopters have issues getting higher without being "equipped" for it. I do believe it is relevant info.

[@browniesr4theweak]

Exactly, Flying drones I think of the same sort of concept, Air is mass which you could push off of 🤏🏽👓😳

[@TheGbab]

I feel that somehow suspending mass and shifting the rotor axis in a thrust direction could help with lateral speed. basically configuring the center mass, batteries etc so that helicopter type flight can be achieved. it has great potential for going straight up. lifting a camera, radio antenna, or spotlight.

[@ellenorbovay5226]

The centrifugal force seems to make it more stable, that design seems to have a lot of potential.

[@stevosauve]

Early gyrocopters solved a similiar pitching issue by allowing the blades to flap up and down as they each transition from advancing to retreating during fwd motion. However, with your design, this would create other problems. Alternatively, you might try a means of dumping lift on advancing blades. A spoiler hatch in each main airfoil connected via cable to a gimbal ring that shifts with your cyclic control

This is a fabulous creation! Very refreshing to see the Levitator floating so gently under your careful guidance. I'm curious to learn what kind of stabilisation and control system you are using? Thanks very much for sharing.

[@gsmontag]

This design is extremely promising as it would scale favorably with size, at least to a point. I'd love to see a slightly scaled up version with more robust control surfaces, possibly ones with flaps for spin up and spin down/landing where the rotor is moving slower, and retractable into a shorter control surface as the rotor speed increases. And as you pointed out, stronger and faster servos would make a big difference. Another approach to consider is a dynamic wing/lifting surface that can flex or change shape to optimize performance at different speeds or if fast enough to act as a control surface itself.

[@younanpolousy4345]

I like it 😊 you did perfect design 😮 this is small version of future crains😊 Good Job 👏

[@hostingwithhenry6716]

Your channel is very inspiring. Please accept these three possible modifications to your model for testing purposes ( I really believe that other fans may agree that a Levatator is different from a Hellicopter ). Please allow the Levatator to always fly Flat as a pie pan ( lateral movement can be added without any tilt ). A Gyro / Gravity corrector could be completely On Board. The Lateral Movement is where the RC Control belongs. It can control the Angle of Attack of Radial Vertical Darius Rudders ( extending both above the wing and below the wing ). As the Levatator hovers in a complete stable flat plane, the Vertical Rudders are the Cyclic Drive. It should move very smartly in any chosen direction. Each wing controls the Angle of Attack of it's own Horizontal Aileron. The only Pilot Control is Throttle and the Cyclic Angle of the Vertical Thrusters. Your Tilted Flight on the Quad Air Chair was very much a call for Level Flight. This Concept does scale up. The only additional Control is an Air Fin on the Pilot Cab to allow it to be rotated relative to the direction of travel, or while Hovering to see different views.

[@Allan-mf1he]

Would it steer if you offsets the center of gravity? Like a weight on a controlled 3 way controlled ball swivel. Interesting machine!

[@myotherusername9224]

weight shift. Good idea. I always thought of that as being the reality of rotary wing flight anyway_ helos and gyros. You're moving the rotor disk relative to the CG. IN a sense that's how all aircraft fly, with reference to the CG. it's the major unacknowledged contributor to control in everything, even bicycles.

[@PCMcGee1]

I love your process of iteration, testing, evaluation.

[@GewelReal]

[@senorjp21]

I saw a monocopter that used differential thrust for lateral control. That system required computer vision to determine the angular position, but you already have a stable commutator, so that might be simpler for your craft.

[@erobwen]

One interesting way to transition to forward flight would be use the wings as ordinary wings in forward flight by tilting the entire machine 90 degrees and lock the rotor somehow. There is a video of a drone with similar design somewhere on youtube.

[@youtubeloveTed]

Nice work, thank you for not giving up 👍 maybe if you skip the main battery pack, just use enough batteries to maintain a stable flight and make the wings covered in solar cells. 😅

[@nanskate]

Looks Great, Awesome project. Thanks for trying the dihedral, interesting. For a lot of control authority, you could try to make the motors pitch up and down. They are far from the CG, should work. (Maybe even better than the surfaces?)

[@Pystro]

It would certainly be easier on the servos. In the view along the control surfaces you see that the air stream really does what it wants with them and flattens them out to 1/4th the deflection they want to have.

[@unnikrishnannairkrishnannair.]

70% diameter from hob is feeling neative pressure in axial flow propellers. So that shade that area from top. 30% diameter help to produce 100% positive pressure. It is found by pressure distribution over various radii from hub. 100% pressure at tip and 25% pressure at ceter of radious

[@margou6534]

Always think outside the box brother, this probably has a really important application dude! 😊

[@patrickfle9172]

With a counterrotating system you might not only equalize lift on both sides, but you could also use the little propellers for propulsion by addin power on those that momentarily point in the direction of travel and reducing power on the opposite side 🤔

[@BrightBlueJim]

Since the rotor is rigid, that is, the angle between the blades is 120 degrees at all times, this would not help. It COULD help if the blades were mounted flexibly to the hub, such that each blade could speed up and slow down cyclically through the course of revolution. That is, the blade flying into the wind could be powered less, so that it falls behind, and the rotor flying away from the wind would be powered more. This could, at least until a certain flight speed, even out the relative air speed on each blade. He alludes to this in the video, saying that the blades don't "flap", or lead and lag (which is what I'm talking about).

[@patrickfle9172]

@@BrightBlueJim that's why I wrote 'counterrotating system' aka coaxial double rotor.

[@BrightBlueJim]

@@patrickfle9172 Yes, the counterrotating rotors would equalize the lift through the whole rotation. I misunderstood what you were suggesting - adding power to the propellers on both sides that are facing closest to forward would indeed give some thrust in the desired direction, and as long as power was increased in a balanced manner between pairs of motors on the two rotors would do this without throwing off the balance of the system as a whole.

[@jlvandat69]

First time viewing your Levitator 3 and immediately see some significant advantages to the design verses conventional helicopters and fixed wing aircraft. At 7:00 you point out one inherent safety feature- the attitude "self-correcting" feature that results from ground effect. My guess is that your weight to power ratio is better than conventional helicopters due to several factors such as slow blade rotation and the absence of a tail rotor. My initial impression is that this design has good potential for personal flight and the autonomous commuter aircraft industry although forward flight speed capability limitations will limit that applicability. Very interesting, innovative design.

[@thedevilinthecircuit1414]

Beautiful and elegant! Looking at your control surface connecting rods, I think you might get more strength by using a small fin rather than a post to join the control rod to the control surface. Sort of like a little vertical stabilizer. This would be stronger than a post because the control surface reciprocates with each rotor rotation. A fin-style bellcrank would give more control authority because it will be more stiff--joined to the entire width of the end of the control surface.

@@GoldenCroc Solar planes with crazy flight times whether they are r/c models or full size have been achieved. My question is could you use the light weight 3d printed solar panels developed by the Australian CSiRO as the surface of the rotors in this design to achieve sustained flight in full sun. (Probably somewhere like Australia or Spain that has decent solar intensity). Another idea is a pusher prop placed at the C.O.G. rather than lower down to help lateral speed.

@@MrBoatman46 Well yes I know, but I thought you might be interested in the comparison of the concept in any aircraft. If you werent, thats why I put "If you want rotorcraft, yeah why not" in my last comment as well.
