- A complete walk through of Ikarus II which is an upgraded version of Ikarus [ • Ikarus electric "rocke... ], a 3D-printed, Electric Ducted Fan UAV that takes off and lands vertically, sort of like the Falcon 9 first stage.

Welcome back! I look forward to Ikarus III with its 4 ducted fans.
4 fans = drone 🤣🤣
Ikarus III will only have 3 fans, with one rotating in super position.
It very efficiently and evenly relocates dust in any enclosed space :D
I need to build one just for that purpose
I've just realized that this has might have the potential to fly horizontally with quite high speeds. Maybe needs an addition of two short wings on the sides. Nice progress!
Buzz lightyear...
@@Doom2pro lol straping a toy buzz lightyear will be fun
And with addition of a small foil or wing...
Yes! This is on the list for Ikarus 3
I thought so too! Fold-out wings could be a great idea if the weight can be kept down.. foam and plastic/CF tubes for extra rigidity maybe?
He's back, only this time with adds. Congratulations. Love your style.
maybe make a video on your athletic progress? what motivated you, what program you followed, what diet, etc?
This is amazing. Ikarus 2 is beauty but I still think what you managed to do with Ikarus 1 is just art.
i've recently gotten into quadcopters, and every time i tell someone they're like what's a quadcopter, and i have to sigh and say "ya'know, like a drone?"
Wow a tesla500 video! Good to see you again!
5:58 oo I've never heard of antibacklash systems
thats really cool!
thank you for teaching me of their existence
A nose cone and a minimal airfoil could make this into an absurdly fast EDF missile in horizontal flight
Why would you block the airflow with vanes if you can use your surfaces on your airfoil for controllability.
@@MrJob91 So you can hover
You grossly overestimate the power of EDFs. Open prop is much more efficient and powerful.
@@drkastenbrot he didn't say anything about building the fastest possible horizontal flight craft ever made. Those ducted fans would make that go super fast in horizontal flight.
@@drkastenbrot and it's not as simple as saying open props are more efficient and powerful. Not even close.
No only is this thing just awesome, it looks like a 48 IDF Weber carburetor too👍
yes!
Metric units do bring a smile to my face
The jitter in the control surfaces looks kind of cool, in my opinion. Makes it look it's alive, organic.
Either that or a hyper-caffeinated squirrel.
I love the beeping this thing makes on startup lol
Why are you the only (other) person who knows what the word "drone" means? Thank you for that. Cool project.
He has returned. Awesome project
Laser cut petg vanes would be indestructible. Love the anti backlash genius!
Just needs self righting legs that fold out like petals, and a fpv camera.
That flies remarkably well. I will be following with now with interest. Great post.
I quite like the anti backlash springs idea 👍
haha love the rib jab at Technology Connections pedanticness
Oh wow you cleaned your bench! ;3
Welcome back! EDFs are great. It’s actually hard to manufacture bearings that work at crazy high RPMs.
I'm disappointed it's not just one much bigger EDF. Seeing a dual EDF kind of makes it pointless but still kind of cool to see.
For the next version you should consider 2 counter rotating fans in a single duct.
I've been following you for a while man really enjoyed your videos, the idea is amazing congrats man . Cheers mate
This is really cool
1:24 nice tech and health
I feel like the next version of this VTOL will have 4 EDF's
There wasn't better names for something flying above children.
You can make most edf counter rotate by swapping the positive negative wires on the brushless engines
RC Martin Jetpack... Interestingly they found that a higher C of G improves handling qualities.
I had assumed that as well. Longer distance lever arm from the thrust vectoring vanes to the CG should improve performance.
Hello, really appriciate your work and you, for sharing knowledge and experience with us. I could not help notice, that you actually solved the stability issue, that many "jetpack" developers struggled with, in a larger version. Some of them, never managed to make software aided stabilization. You did it, and share it with us! BTW, seen the movie, "Rocketeer"? :) As for "jetpack" I settled myself with the idea is not viable, since such a configuration need to move a lot of air (loud and energy demandig) and a single component failure is a disaster for the operator. And then, the idea of accelerating a lot of air in a smal area, result in compressing air in a such degree that the efficency is low and energy demanding (gas laws).
1:25 There are alotta "ghost orbs" in this shot.. ghost hunters woulda gone crazy..
oh wow amazing to see progress being made on this, looks super stable now
also going by the naming convention of icarus 1 being single fan and icarus 2 being dual fan, will we see icarus 9 have a 9 engine layout like the falcon?
Great work! Let me know when you develop a leaf blower version, so I can blow off the driveway from my rocking chair.
3:30 "this one runs on success"
and everything I've ever made runs on the opposite
For high discharge batteries I use CNHL 120c. Might be worth checking out
"Ya no prob babe, I'll sweep the porch"
Can I borrow your leaf blower? Mine stopped working. LOL...that thing did great blowing off leaves and loose grass!
I love it.... keep up the great content. If it's not too much to ask, would you still try to perfect icarus 1? I'd LOVE to see a single motor EDF fly with flight control vanes alone.... that was your goal from the beginning, right? I've been following along....
It has 13 HP! That's mind (and gravel) blowing.
Have you considered having extra servo per EDF that spreads apart the vanes? This would let you quickly control the effective thrust of each fan allowing for much faster response than only by RPM variation. With that fast airflow this method of thrust shaping should start to be effective already.
what an unexpected upload.
I could not stop thinking, it would be even easer to use 4 motors 😅. Personally I'm a big fan of the one EDF design. counter rotating blades in one housing would be cool though. Non the less really cool project.
Man imagine that thing once it does a full 90° once it’s at height
Maybe put it into ball like protection? I think it also needs drone hardware for auto hover and self stabilize, and camera )
The control surfaces works better when the rear edge is blunt. It increases efficiency for small angles around 0 (for the cost of a higher drag).
I'm curious to know more about this. You say increases efficiency, efficiency of what?
@@tesla500 increases efficiency of deflecting air flow.
When the rear edge is sharp it feels like a dead zone around the central position like the control surface does nothing.
Easily testable on small hand-piloted models ;)
Depends on the whole airfoil, especially if it is a part of a bigger stationary surface, though.
4:10 have you experimented with the tougher and less brittle resins?
I also believe you can also add some flexible resin to your hard resin and get the equivalent of a plastic alloy of the two, so its less likely to shatter
I, too, prefer fdm of resin for structural parts, though
*fdm to resin
Given any thought of placing the ESC mosfets in the air stream or bonding them to the metal housing of the duct? Assuming they will get toasty for longer flights as the data sheet looks like they need absurd airflow for the continuous operational spec.
Yes I'm planning to use thermal pads to connect them to the EDF housing. I was thinking of placing them in the ducts initially but this just made so much more sense layout-wise, considering where the servos are mounted, and the space between the fans due to the inducer ring.
it's a "low altitude object".....cylindrical in shape
Id recommend you try a low flexibility resin rather than a solid resin
The Form 2 parts just need a different resin. Zack Freedman has a recent video on printing resin Nerf blasters, which typically have parts prone to failure due to the spring forces of the blasters. He found that some of Siraya Tech's resins are good for blasters, which he settled on a mix of 5:1 Blu to Tenacious, for better performance when it comes to screws not pulling out. If it's good enough for a blaster with high spring forces, it should be more than durable enough for the parts you're printing.
Personally, I think a horizontal flight variant of Ikarus based on this design should be left as a version 2.5. An Ikarus 3 should explore three EDFs, similar to how a tri-rotor performs, this could also explore various other forms of control, such as tilting the EDFs rather than using veins for a vector; doing this with two degrees of freedom, either with some kind of spherical joint or with a gimbal, could also make the transition from vertical to horizontal more interesting, as you wouldn't be tilting the entire craft but instead only changing the position of the EDFs. Ikarus 1 was a mono-EDF, Ikarus 2 is a bi-EDF, Ikarus 3 should be a tri-EDF, which would leave Ikarus 4 and 6 to be a quad and hex, etc., which would also leave Ikarus 2.0 as vertical-only craft and 2.y as a vertical and horizontal craft, similar for 3.0 and 3.y for a vertical-only and vtol with horizontal flight variants, as an x.y naming convention. Personally, I think the best naming convention would be x.y.z.α, where x is the basis of the concept (mono-EDF, bi-EDF, tri-EDF, etc.), y is changes to the platform of the craft (vertical-only, horizontal flight, any other major platform changes such as EDF positioning, additional control surfaces, chassis changes, body changes, etc.), z is supplementary system changes (such as a change to how thrust vectoring works, vein-based vectoring, nozzle-based vectoring, motor vectoring via gimbal, motor vectoring via non-gimbal joints, and incremental changes to other supplementary systems such as if you add active surfaces to wings and those surfaces evolve over time [the initial addition would be a change in y, incremental changes would be a change in z], etc.), and α being minimal changes (such as battery upgrades, controller upgrades, EDF upgrades, etc.); it's just better documentation and keeps a cleaner path of project evolution, not to mention an organized changelog. This would also prevent the issue where version 10 in the current naming convention would be wildly different than version 1 or 2, whereas the x.y.z.α naming convention would keep things more defined. A naming convention like this also adds a lot more breathing room for branches of the project, such as if you do want to eventually explore tri-EDFs and quad-EDFs, the naming convention is built to allow those branches without those getting mixed up with other variations within a mono-variable version convention, say Ikarus 3 and Ikarus 4 rather than something like version 10 and version 20.
If you want a challenge taking this tech to the next level... Expand it out to an RC Starfury from Babylon5 with all of it's 16 thrust points (8 main and 8 RCS).
I'm not totally sure how you would go about actually making the design fly inside a gravity well, but i think it would be fun.
Put a cap pack like the ripple killer on to buffer the batteries.
53 weeks since your last vid! Thought you'd fallen off the earth!
About the same as the current lead time for semiconductors 🤣
So cool!! I wish you were my neighbor so we could workout.....
Nice prjoect! I think you'd get better results by using a more recent flight controller like an F4 or F7. Naze32 is a relic and CC3D is like Adam & Eve..
Yeah I keep designing in old stuff. Is there any good resource listing and comparing currently available flight controllers?
@@tesla500 Not that I'm aware of, but they don't have many differences. Chip speed f411 < f405 < f722 < h7 and price accordingly 30 - 100++€. No of uarts goes from 2 to 9 but I guess you won't need them. All support Betaflight and other firmwares. All fly almost the same although with f411 you may have to turn loop speeds a bit down but even it still flies the same. I'd get an f405 or f722 with blackbox to know what is going on during flight. They go for about 30-50€ on Aliexpress. If you want to see the difference between these and the controllers you used, see Rotor Riot's Kaveman Kwads - video and compare the flight performance with their other stuff.
You ought to look into Engineering grade resin for your frame. A cheap resin I use often is Blu V2 by Siraya Tec.
2nd'd. I know someone who uses the same stuff and swears by it. I haven't got my hands on it yet but claims it's as strong as FDM plastics. Non brittle.
have you considered implementing stator blades? could redirect more mass flow straight downward, possibly make your control surfaces more responsive!
Impressive!
Love the anti-backlash design. Does your first version's yaw work well? (Ie. when all the vanes turn CW or CCW). I had the idea to make something similar in an RC airframe so it would be actually a roll movement and wondering if it would be enough to overcome the wing's resistant. I'm trying to stay away from needing any control surfaces like ailerons for rolling.
Great Content!
Lol this looks weird ,great job !
Throw some super caps on there that might help the voltage sag
10 kilowatts. What????? Something this small can deaw 10 kilowatts ? I just can't believe that.
welcome back!
Ikarus2 almost looks like a backpack.
Really cool. How much weight can it carry? Can one just substract the weight from the thrust and the rest is what it can carry? So, 7 kilos in the case of Ikarus II?
Quick question, where did you buy those spring steel landing legs for this project? I have been looking for something similar for a personal project.
go high c rating batteries, please check the FPV world. Tattu R-line batteries have good performance. What resins did you use on the formlab? Have you tried "durable resins"?
Very interesting
still waiting for the 3
If you regulate the fan speed you do not need 4 servos, only two.
Yes, but then the gyroscopic precession isn't cancelled out if the fans aren't running at the same speed.
Ikarus 4 should be both fans stacked inside one housing, so you keep all the benefits of counter rotation. It should be lighter, but i would expect stacking them would reduce thrust?
Awesome.
Great job
Hey, glad to see you're back. What 3d printer are you using? Resin?
he said the model in this video is printed on formlab. the previoius one and the next one are both fdm printed.
Look up Resion K. ABS like tough resin
Hey since theres no contra rotating blades / turbine fans how are you cancelling out the rotational torque that gets generated by the rotation of the blades? Do the control surfaces at the bottom able to rotate independently and generate yaw authority?
deffinitly a bf4 mav
So cool 😎
Do your 2 ESCs connect to the flight computer / your 5v circuit via BEC, and do you have the positive terminal of one of the BECs capped or are both fully plugged in? (I'm learning how the electronics on these work)
Nice.
looks like oregon or washington.
Have you thought about using AI to make renderings of the turbine envelope and vector symetry... you could also use engine thrust to stabilize and other movements or is it yoking?
What do you use for a power supply that can supply that much current?
Damn dude you're lookin reaaly good these days, buff AF 💪☺️
I have a question about ikarus. Would it be able to lift things? Let's say I am working on a rooftop and I need to bring tools to the top quickly. What's the largest EDF your algo can handle?
If the payload is onboard it's no problem. You could get EDFs about 2-3x as big as this, but there's no real limit to how big you could go with this algorithm, it should scale indefinitely. A conventional quadcopter would be much more efficient and could lift a lot more weight for a given cost however.
I tried lifting things with a string, but it's unstable. It's difficult to attach a rope to a point that allows the craft good control authority, it really needs to be attached at the center of gravity which is not practical without a big gimbal.
I preferred the single fan version because one fan is impressive. But this is also a very good achievement. Are those servo not crap ? Would more precise and fast ones bring more control and feel ? What is the material of the legs ? Nice job for Icarus 3 ! Nice job for removing weight !
Could you *please* redo the single one fan for Icarus 5 ? With all know how you learned ...
Please keep it open source and we'll documented so other can learn too ;)
Great video as always. Did you lose weight? you look super ripped now :D
Can you do more lawnmower drop and shred?
Super super sir
Wow super super good super sir
make a video about the chronos success!!!!
Where is III ?
What material did you use for the form 2? Did you post cure it?
there was something about the previous version having a single axis that made it look really cool. could set these fans to be coaxial?
I was thinking of that, it would basically double the total pressure ratio so the exhaust velocity would be higher. For thrust, it's definitely more efficient to run the fans in parallel (side by side) rather than coaxial, but the higher velocity would allow a higher top speed.
@@tesla500 it's not about performance, it's the cool factor that the coaxial version excels at
@Alexander Sannikov there is an interesitng design by amazingdiyprojects: th-cam.com/video/tEEXPxN7qq4/w-d-xo.html there are newer videos of it as well
@tesla500 Would it make sense to use different AoA wings for a coaxial design? Maybe the efficiency could be similar to a parallel design if engineered accordingly. For instance Turbomolecular Pumps use stages with different AoA fans
@@maeanderdev yeah that guy certainly knows his stuff, I've been following him for years. the coolest part of his design is that he does not need to have a precise control of the main engines and it can be combustion driven for example
Nice 4Runner!
Are you flying with attitude or rate inputs?
Attitude right now mainly, tried rate but I need a lot more practice flying with rate control.
Your jet pack bound if your not careful
Крутая штука!
Would it be possible to compensate the one edf version gyro effects inside the flight controller?
Yes, that's done in Ikarus 1, but it needs a lot more work to fully solve the problems. It flies, but still has some stability issues due to the slow response of the servos.
