Levitator 8

[@TROUROCKS]

dynema for all your rigging .. it has no stretch . easy to adjust.. extremly light . fishing line

[@alexbadillo9940]

Awesome I wish I had a quarter of the skills you have to be able to create these things!

[@okgo8315]

I love this wonderful project and your brilliant development process, so mesmerising to watch. Thankyou from Rome✌️🇬🇧

[@thechumpsbeendumped.7797]

I’m surprised to see you put my collective idea into action so quickly. As the range of motion of the linear actuators is too great could you not put a limiter tether on it or use a single actuator to move both alternatively use a 2:1 pulley to gear down the range?

[@senorjp21]

My instinct would be to put the props in front of the wing to increase airspeed over the wing - admitedly I don't know much about aerodynamics

[@tonysargent1699]

It's nice to see you moving closer to your goals. It is truly inspiring.

[@flaviobr1576]

How about making a conical fairing in the middle, where there are only pipes, there will be a disk and the blades rotating around it.

[@TROUROCKS]

and can go round pulley wheels to redirect to where u want it .. top and bottom rigging can be on spool in spool out drum .. look at sailing servos

[@fabianbohnert120]

Since he already has the linar actuators, could keep them and add a wire to rear direction. Then redirect it with pulleys to the top part of the wing.

[@alternativeenergychannel2289]

Very impressive !! Almost levitation !! So low rpm !! It's a piece of art !! if we find usages in real life it's going to be awesome !! very interesting approach !! 👏👏👏

[@DakovP]

I never understand a thing youre doing, but its always cool.

[@EleanorPeterson]

I don't know much about electric motors and electric flight in general - all of my aeromodelling exploits have been powered by gravity, ether or methanol - but I've spent ages experimenting with propellers with various pitches and diameters, and have arrived at the following conclusion: it's really, really tricky to get right, so just keep mucking around with things until good stuff happens.🤭 Meanwhile, watching the (sexy!) slow-mo footage of your wonderful craft in flight makes me think of it undergoing a series of infinite fractal regressions where the Levitator's main wings are driven round by large motors turning propellers made up of smaller versions of the Lavitator mounted perpendicular to their vertical axis, and these propellers are in turn made up of yet smaller Lavitators, which are made up of even smaller - Yes, you're right: there's a lot of caffeine in black tea...☕👀

[@lohikarhu734]

you could almost use SMA wire for that 'linear actuator' only problem, I guess, is that they need to be powered, although it's possible to build a kind of 'clutch' mechanism to keep them tensioned...anyway, on with the show ;-)

[@petercarbin2077]

Do not know if you realize this but the propellers you are using are APC glow engine propellers which are heavier if you get APC electric Props electric propellers they are lighter you'll get more thrust more efficient on the amps

[@richardlincoln886]

I'm interested in the need for the rotating AND static components. i.e. significant complexity in keeping the static core not rotating - while obviously required to give you a reference for control surface change in position as they turn. Just a comment - i.e. its plainly a straightforward method for the control surfaces to 'know' where front is on each rotation but adds lots of moving parts/bearings etc?

[@souzarefrigeracao]

Você realmente e um engenheiro. Acompanho seu trabalho a mais de 1 ano, parabéns pela dedicação nos seus projetos. Nos brasileiros ficamos impressionado com suas criações. ⚡️👏👏👏

[@derkarhu5079]

I wondered if you could use SMA actuators in a couple of places, like airfoil shape, angle of attack...they are current activated, can be quite fast...one downside is that they can require constant power, although you can also use a kind of brake/clutch to hold the activated position

[@lohikarhu734]

another crazy idea... could you mount the motors in front of the wing (near the tip, of course), to get advantage of the high-speed air from the props??

[@mikaelreichel3759]

Typically airfoils begin stall at 15 degrees. Perhaps the increased current at higher AoA is begin of stall drag?

[@ArnoldsDesign]

This reminds me of a no torque helicopter that they used to offer the plans for in the back of Popular Science magazine years ago. I bought the plans, and it was a little two blade ultralight helicopter, and it had two Zenoah 20 hp engines with propellers turning the rotor. It was pretty cool, though it had no hinges to to control increased one sided lift in forward flight. Your design is unique in that it counters that by increasing or decreasing lift via ailerons instead of changing the entire rotor aoa.

[@andrewgardner7104]

Thanks for all your time and effort I really enjoy your exploits

[@botulin1443]

Tricopter to spin vectoring will require a lot more power. A small drone can vector easily because of small inertia.

[@yanenkogg]

Идея отличная, но мне не нравятся двигатели с пропеллерами за пределами крыльев!

[@thatairplaneguy]

Why gas/nitro props instead of electric?

[@petrikarkela6800]

I wonder if you should have the engines tilter a bit upwards? That would prevent propellers to pull downwards when turning.

[@petrikarkela6800]

I meant tilted.

[@petter5721]

Bra jobbat 👍🏻

[@raylawrence1]

FURTHER TO COMMENT BELOW - SEE VID AT 5:02 WHERE WASH-IN AT THE TIP CAN POSITIVELY BE SEEN

[@JustAnotherBigby]

I wonder if the top tension could just be a spring rather than another actuator.

[@86locomotivebreath]

Your work and results are fascinating and impressive. Thank you for sharing with us. -California

[@ПавелИванович-г5з]

Hello please help me I'm from Russia I'm to Chechens

[@derkarhu5079]

Kind of cool having "talking ammeter"

[@Jkauppa]

cl-84 tilt wings with the upright rotors on the tips

[@ERIUVTOL]

Do you know this one - its pretty similar

[@dwk5234]

Your structures and your control systems are highly impressive…beautiful work! At higher speeds, I would think that parasitic drag from the wires and round tubes would become a factor in efficiency. Looking forward to your next iteration!

[@DrHeisenberg]

It's so good to watch a full-on nerd doing his thing like you do. Beautiful craft, I seriously believe this will find it's way into sports events and the likes for seremonies and show purposes. Just imagine it at the Olympics opening seremonies. I'm thinking you might want to consider experimenting with winglets at the wing tips for improved efficiency?

[@malloot9224]

This craft could be scaled up massively I think, seems like an effective way to do heavy lifting

[@ERIUVTOL]

Great Job Anyways 🙌

[@idjtoal]

I thought the end sequence was slowed down, to show details, but it doesn't seem to be? Pitch of the motors at the very end seems normal? Unreal, this concept craft is just amazing to watch.

[@amazingdiyprojects]

Last section is slow motion.

[@idjtoal]

@@amazingdiyprojects Really, oh well, seriously thought you were basically violating laws of physics there or something. Next project for that, maybe. 👍x10E^6

[@poporbit2432]

Love your approach

[@jaspersonnyoner]

Cool you made this change so rapidly. How are things going?

[@amazingdiyprojects]

Just fine thank you! Im working on a more fully featured and scalable 4-wing version destined to be controlled by a pixhawk cube orange flight controller to get all that goodness that comes with a more advanced FC/autopilot. I hope to start flight testing and posting videos of the new setup early spring 2023 🙂

[@jaspersonnyoner]

@@amazingdiyprojects Nice! Are you hoping to man the next flying machine like you have with previous projects?

[@amazingdiyprojects]

@@jaspersonnyoner The (optimistic) ultimate goal is to build a version so large (hover efficient) it can fly two persons for an hour. For now Im still in model scale (1:5) with the short term goal of matching the vehicle to the pixhawk flight controller and try out various redundancy features. If a redundant setup turns out to be practically possible, and a new take-off mode which eliminates the need for a separate dedicated landing gear/skid (the current skid design does not scale well) turns out favorable, the big one (26m-ish in diameter!) is ON! 😀

[@Alexander_Sannikov]

when i suggested variable pitch mechanism, I was thinking of having a single hub sliding vertically with a single actuator that all cables are attached to, instead of 3 actuators. I think one servo with a shared hub is lighter and more reliable.

[@ashleysmith3106]

I imagined a internal sliding shaft with actuator with cables attached top and bottom, but it amounts to the equivalent of your idea of a sliding hub anyhow.

[@raydebs]

To improve the efficiency, use single-blade propellers and have them turning the opposite direction against the normal vortex created from the wing lift so they will reduce that drag as well.
