How much all this setup including 3d printer, instruments to check thrust costs?

I think you should reprint it all in PETG, and I think your wall thickness was 4mm, make it 3mm. Than make it all thinner, you might be able to cut down all the plastic weight by 50%. amazing job by the way, I love it

PET-G has a higher density than PLA. Nylon probably is a better material for such a project. It's less rigid but more resistant to snaping. Or maybe Nylon with carbonfiber

I was like pfft whatever i 3d print frames too, then i saw it was the ENTIRE quad, motors and all. bro this is incredible! great job.

Arguably, having a somewhat fragile retainer for the props can be a good thing. On impact, something must give, and personally, I'd prefer to make the engine's rotational force eat a small 3d printed part rather than smash the daylights out of a much more spendy prop. I'd probably say, if it's strong enough to transfer normal levels of torque, it's dimensioned correctly.

True, as long as it really doesn’t fail in flight at some point and cause a much more catastrophic crash.

One of the benefits if he were to print the retainer out of PETG is that it tends to fail catastrophically with a repeatable amount of force rather than slowly and unexpectedly. Makes it useful for printing predictable mechanical fuses.

the thing is that you should make that easy-to-broken parts also easy to replace. It would be nice to add an easy to replace stress raiser for the arms support.

As the great engineers said - with a good engine, a stool can fly. In this case with a good battery.

PLA Pro is strong and has a matte finish. Also I'd recommend grabbing a bottle of Weld-on 4 and some pipettes. You can literally melt broken pieces back together without heat and make nearly seamless repairs to PLA projects with about 80% of its original strength after it cures.

Dude you are awesome, this is so impressive! I've always wanted to get in to stuff like this but don't know where to start so its really cool seeing a guy I can relate to getting out there and doing it

I personally have been using on shape for over 5 years now for simple CAD work and it's been amazing! It's also completely free, as long as you post your models publicly. I've compared it to other CAD programs like solidworks, fusion, 360, etc, and it holds up every time. Me and my engineering co-worker design things all the time on it, and are both able to access the file at the same time and see changes happen in real time. It's definitely my number one go to CAD program. Awesome build by the way 👍

TinkerCAD is a slimmed down online version of AutoCAD and has most of the features anyone could need, and they don't require you to post your design for free.

Awesome! Congratulations! I love the generative design of the frame, beautiful and functional. Bravo.

Adding random fans is a form of self-care :) Such a cool project!

I still think it's crazy that the motor cores are 3d printed as well. Also definitely print blades, it makes much more sense for the project

Congratulations once again. Incredible project!

after having watched the next 9 minutes and 58 seconds I would like to see FPV and think it could be fun to watch 👍

Such an inspiring video Michael. Keep it up!

The 3D print is deliciously amazing! ❤️😍

Loved it mate, very cool project!!! You’ve got amazing skill with 3D printers

Great work 🔥🔥

woah, this is extremely entertaining and fun to watch. It's the first time i've seen someone be this creative with a Quadcopter.

Great Effort i love this project. by the way congratulation for ur success flight.

amazing stuff man!

Amazing work

Very cool project. I subbed to follow it. The fact that you made the engines is the most impressive part to me. These would be my suggestions based on printing... let's say load bearing parts: Use PLA+/PLA Pro without any further additives like silk or glow-in-the-dark. More walls = more stronger (usually). Use an infill style that gives good strength in all directions rather than a plane grid or similar. I hope to see you develop this drone further.

Really impressive work!

Finally watched this! Fantastic video, love your projects! All I can think about is how much weight you could cut just by drilling out some of the extra plastic.

I am truly impressed by your CAD design. Nice job

The figure for a safe landing, and you are amazing

Those engines are sikkkkk. Most impressive part of your build.

Это потрясающая работа!!! Вы большой профессионал!!!

Awesome build bro

I love that you picked a Noctua fan, because noise levels are really a huge concern! (yes, I know they can have higher flow rate too)

This was such a cool project

TOTALLY AWESOME IM SO HAPPY IT WORKS!!!!! 🎉🎉🎉🎉🎉🎉🎉🎉

You got my sub!!! Great job!!!

great, thanks for sharing 👍

great work.

Amazing!

Very cool!

Oh for for the love of it!!! Your telling me the 10mm goes missing in the 3d printing hobby too. Dam it!!!!

I would guess you could scale this up probably by double (including prop size but maybe not double) those motors must have some serious torque that might be underutilized even with 3 blades. Awesome project thanks! I've been following the motor project since it's first upload and have been anticipating this project ever since!

Great video

Dude good shit that thing is sweet🔥🔥🔥🔥🔥🔥

Cool quadcopter

That’s very cool. I’d like to see a similar project but with weight reduction like off the shelf motors and electronics, more of a 3DP race drone with fpv.

I like the touch of adding an additional fan to a thing that is basically made of fans.

Nice video, thank you for sharing it :)

Interesting! I'd love to see it with a camera turret or some sort... But FPV is also fine!

You did it. cxongrats!

Congrats for making this heavy thing fly so nicely. 👍 You could try printing different blade shapes and configurations. I've seen number of people claim they have great success with toroidal propellers. 💙 the colour scheme (and the quick release wings).

Cool project, it reminds me of my journey building quads 15 years ago. :) I'd ditch the PLA and use PETG or even ABS (since you have a Bamboo Lab printer). You can also 3D print the props, but I doubt you'll get better results. There are some new cool designs for low-noise props you could try. Good luck.

i love how beefy the motors look. impressive build!

They look similar to the Christoph Laimer design (KZread channel by the same name), however this design looks like it has improved cooling vents. I hope Michael talks about this.

Consider switching to using ASA as your material. It has a roughly 20% smaller density which could lower the overall weight of your quad and allow for greater flight times. ASA is also UV resistant so when you fly it outside it will be able to handle the temps and UV radiation better than PLA and won't approach the glass transition stage during flight, which needless to say, would be catastrophic. You could also potentially use foaming ASA or foaming PLA for the arms and main body if you were to provide it additional stiffness by inserting smaller diameter carbon fiber rods (this is the approach I am using on my 3D printed robot dog to reduce mass/inertia). PLA ~ 1.25 (g/cm^3) ASA ~ 1.07 (g/cm^3) LW ASA ~ 0.47 (g/cm^3) @ max foaming So if you changed to using the LW ASA at a more moderate foaming of around 0.7 (g/cm^3) you could have a roughly 45% weight reduction while gaining UV stability, greater operating temperatures, and longer flight times. Just some thoughts! Great work so far! Absolutely loving this project

congrats! 😄😄

Love it

I love this project! I would really like to see how you get on using 3D printed props

3D Printed Torodial Props is perhaps suitable for the next modification

very nice, also to see BUT seems very heavy to me and yet proof has been provided 3D printed and flying hats off! or... respect!

Love it! Adding the fans seems like asking for trouble though. Fans spin due to air and send power back to controller.

Fantastic, of course! At 5:03... This irrefutably confirms my hypothesis that the degree of control is the inverse of the pilot's torso angle. 😉

How amazing turned this project out :D It would be amazing if you add FPV functionality with OSD information. Maybe you could also build a smaller drone version with FPV functionality that could land and load on top of the larger drone. Also you could made your own torodial props :)

Удачи в остальных проектах.

I would love to see how this runs with toroidal propellers. This is such a cool project, my boys and I are going to build one. Thanks for sharing your projects with the world.

Badass!

after having watched 18 seconds of this video i can say its great 👍

Great project! Intuitively, it feels like raising the PID $I$ gain would solve the drifting issue without needing to hard-code in the ESC or FC that a motor produces less thrust. I'd be curious to see if this idea actually works.

Have you considered le asa filament? It has a blowing agent that makes it puff up so it is super light weight and does have impact resistance.

man grait video, i would love to see you try printing and experementing with these new MIT torydal propellers

Great work! I'm definitely gonna subcribe to your channel for more! 😁

Pretty impressive.

Nice video ❤

How about using Polylight Lightweight PLA for printing? BTW the stories about PLA's biodegradability are exaggerated as 5 year environmental test has showed very little change in structural degradation. Only the colour faded.

Really cool! I love your approach to experimentation and learning. I'd be really interested to learn about generative design and what tools to use for it. Did you do this with onshape?

FPV! I want to see you try to Freestyle it! COOL

Hi Michael, gret project and videos indeed. I have a question, I was wondering if you have any video/tutorial about the flying controller that you built for this drone...?

What is more needed than a fan? Fan with temperature controlled speed! :)

If you have the X1Carbon you could print the parts in nylon carbon, would be lighter but more expansive. There is also something called light PLA but I think it would be more fragile. Great video thank you.

Yes. Awesome. And fpv.

Very good work!! You could add a accelerometer and have it stabilize itself. I don’t think it would add much weight. What was the reason that you didn’t print all of it it smaller?

Amazing project. Just wondering why you decided to build your own motors? Seems like it would be more effective to go with COTS ones that probably are very energy efficient. Great work!

Dude made his own brushless motors, WOW!

Add legs to your drone you getting some really hard belly flops there Great job overall and please keep ups the good work!!!

love your videos micro rectum!!❤

Ey bitte weiter und mehr Videos auch abgesehen von cupra, du wirkst sehr sympathisch!

Defs FPV it ! Also when you are done please send it to Joshua Bardwell to do a video ! ❤

I did a double take at 2.5kW... insane

What is your power to weight ratio? What is the load on the motors (or operating temperature)? For efficiency you not only want 2 blades but big diameter 2 blade props. Going to higher voltage can help reduce temperature (assuming same wattage).

rule of thumb for a freestyle/racing fpv drone is 20% weight for motors, 40% weight for battery, 20 % for frame and electronics and 20% weight for the action camera (racing drone don't get the action camera so they are lighter and faster)... so my first idea would be to make much lighter motors. also you can swap your ESC to make sure it's your 4th motor that is weaker, that is if you didn't use the same esc for all four motors on your thrust bench test. I am impressed by all the hard work you did for this video... I typically assemble my drones in 1 to 3 hours, but it looks like you spent at least 100 hours on this :) I must say your result is much prettier to look at. Also 3D printed frames introduce a lot of vibrations making tuning much much harder than using lighter stiffer carbon. It's also way more fragile. I guess you will need to find a balance to use more carbon for better results while still finding a way to 3d print some parts to keep your sponsor happy.

This guy just casually says it takes 2.5kw like it's no big deal ... I wish I was making stuff like that
