Nice job! I'm a flight engineer on Sikorsky S70 helicopters, keep in mind that theory of flight for rotating blade aircrafts has a lot of detail and tricks you have to overcome in order to make this project and see it airborne! I'm sure it will be a total success my friend!
Im a system test engineer with 12 years in aerospace and what I learned is that flight dynamics are junk science . Get your L/D and balance correct and just start flying and gain tuning . No simulation had accurately modeled the the details shown in rotor dynamics .
No need to fear flying contraptions. You can actually design model aircraft by gut feeling and estimation. You can get almost anything airborne if you use common sense. The fun is making it efficient. Flight dynamics is only important when you are pushing the limits of weight and strength of your material while having room for a safety margin. As there is no pilot onboard this thing and there is not millions of dollars invested in the test aircraft, you have the ability to try, fail and learn. @@dsanti4069
Please don't abandon this project, projects like these were the reason I subscribed to your channel about 6 years ago. Being an electronics engineer myself I really enjoyed your projects on radio control planes, Electronic Speed Controller, hexapod and several other electromechanical projects. You became an inspiration of mine at the time of my bachelor. As always, great job with the video. I would love to see this fly.
It's great that you are still making videos! For me this is as enjoyable as your more polished videos. I understand that you have limited time, so it definitely would be great, if you would make more videos like this rather than none at all. What comes to the project, it is interesting to see if the resin prints have enough strength to fly. I myself have stayed away from resin printing due to the mechanichal weakness of resin printed parts, although they have great resolution.
Thank you for not giving up regardless of low views and still producing videos. Btw thank you for this video. Waiting for your finished sla printer project
Sorry to hear you're having TH-cam trouble! I hope you are able to continue as I learn and enjoy, watching your channel! Congratulations on your becoming a father too! I know the feeling of burnout! 😅
please keep posting videos, i have been seeing your channel throughout the lockdown, for about 3-4 years now. i really appreciate the diy aspect of it. thankyou for this knowledge. also, wish you and your family a happy new year and merry christmas. congrats for being a father.❤
Dear TH-cam, we as an audience definitely like this kind of content! Please let the people who makes this type of content (including me, gne gne) not be affected by your algorithm. Because STEM educational video's are helping everyone learn from each other and ultimately improve the world we live in. A phone dropped from 2 stories does not. Thanks on behalf of all makers on youtube!
Thanks for this great video,and concerns the algorithm,you are right,it is not like before,that is my opinion as well.i wish you all success,thanks again for sharing.
Sir please make a video of its flight controller. I had started making this project 2 months ago and got stuck in the programming and the Arduino flight controller Please don't stop making this series You was the first who made my interest of mine in electronics You are the best electronics explainer I have ever seen Thank you for this video :)
What an undertaking! Amazing job my friend! Don't forget about gyroscopic precession when you're programming the flight controls. If you want the helicopter to fly forward, the main rotor disk needs to tilt left or right, not forward. Left or right depends on clockwise vs counter clockwise rotation. 👍
for the record im 12 and i understand all of the things this man is sayin and now i wanna build a hellicopter myself thx for the inspiration gret vidio by the way
Congratulations! It sucks that TH-cam is making this changes but in the end what counts is the views. Merry Christmas to you and your family! Can't wait to see this helicopter flying!
I'm sure it will fly but I'm not sure how durable it will be. You can only do so much with resin plastics but there's new compounds coming out all the time to address these limits.
I think making the swash plate a little beefier could help; probably didn't have enough clearance when inserting the threads. you can try your luck with small wood screws as well, as they don't require thread inserts
you missed one thing about the rotor cyclic control... the moment is applied at 90 degree (+-~5 degrees) from your maximum angle of attack position... so if you want to go forward your maximum angle of attack should be on the right (assuming clockwise rotation)... this because of the rotor dynamic response (lagged response): you rotor response at 90 degrees after you apply max pitch... so your body pitch and roll will be switched...
@@antonioesposito8071 i already wrote (+-~5 degrees), its called swash phase lag... actually, its not "much more" complicated... all the helis i worked with or built simulators for fall in this range... depend on blade properties , hinge type etc...but nothing that a pilot cant trim or compensate for...
Answering your question about other options for the circular part with a hole for the bearing, you can use the 3D printer and use a material called PCCF filament.
Such an awesome explanation video! Even though I've seen the angle stuff both in real life and on RCs and all that, I never knew it worked like this. I always thought you tilted the helicopter forward to go forward. Of course, there are probably helicopters that you have to do that also, I don't know.. but you explained perfectly how this type of design works! Thank you! ❤ All your videos are so amazing, you always have something new and cool to watch, I can't imagine how much work that must be for you. Awesome work! For me, I sometimes have to visit your channel to find your videos, I don't always get them in the feed. I have the bell and full notifications on, but that happens to some channels, I don't know why and it is really sad because I only subscribe to channels I love. I hope it gets fixed soon for you! Have a very Merry Christmas and a Happy New Year! 🎄✨❤
The 8-bit guy said the same thing about his TH-cam views recently. And yea, sorry. Honestly, I forgot about your channel until it was recommended just now.
Great video!! Awesome project as well :) The only thing I might add is that you sometimes talked about the same thing 2-3 times, which could be exhausting for some and lead to them leaving the video. That doesn't bother me luckily, but I could see how someone might be bothered. Other than that, AWESOME!!!
I had a think about your swash plate and I think I spotted a mistake: if you look at real helicopters the balljoints coming up to control it and the balljoints going up to the blades are co planar. yours are offset in Z, probably means there's weird loads on them just from the geometry.
An interesting video and project. I look forward to seeing this project some more in the future. I did have a thought. Before the algorithm changed when you used to get more views, were those greater number of views from subscribers? I'm subscribed to a lot of TH-cam channels so that I can see what content they put out. But the only channels I watch without fail are your videos, GreatScott, Mark Rober, and Jlaser. The rest I only watch the videos that interest me. So perhaps it could be something similar here. That still doesn't change the fact that TH-cam apparently changed the recommendation part of its algorithm. In any case, I completely understand having to take a step back and post less. We all get burnt out. It's amazing you find the time with a newborn. As I said in your other post, I've got a 7-week old myself. Just finding the time to get anything done is a struggle.
Excellent! I have subscribed. I have flown RC helis since 1986. Schluter, GMP, Excell and everything until present day . Blade holders and hub look kinda weak/strength. Glass nylon injected are quite beefy. Luv this. Best regards !
Awesome video, I would say that something like "Ingenious main rotor of helicopter mechanism explaind on 3D printed model | I'm making a fully 3D printed RC Helicopter with Arduino" as name of video may work better for clicks and therfore for algorithm. And also I thing that the watchtime is important for algorithm more than comments and likes.
felecidades, congrats papa electronoobs! My little girl is almost 2, yes my hobby time has 📉 but I love learning, and you never stop learning with a baby! Your baby is lucky to have such a cool and intelligent parent!
Hi. Nice job so far. But if i can give u 2 tips, mini servos is strong enough for those size blades. Not to sure if the ones u showed is that size. And tip nr2. Your blades grips. It would be better to have 2 normal bearing about 7 or 8mm appart and then a thrust bearing. This wil prevent stability and blade tracking issues. But anyways. Cant wait to see the first flight. Good luck.
Don't worry man. I am with you always as a fan. Every Sunday I came to your channel and checking any new videos that you have uploaded or not to see your new videos❤. I thought to contribute some money from India. But if it converts to your doller then it will only offer for cup of coffee.
Such smol resin parts don't seem like they would have the sheer/tensile strength necessary to make your rotor/swash parts. I hope you are able to find the right shape/ material. Have your considered fiberglassing a shell onto the printed parts?
@ELECTRONOOBS , i think what happen your channel is about the new YT algoritm to avoid using adblocks, so peoples using adblock maybe cannot watch YT videos,and your videos dont reach them... I wish best luck and a happy new year ! a hug from brazil
You do all your cad work in blender!? Why don't you use fusion 360? I learned modeling in blender but immediately tried fusion because precision modeling in blender was a nightmare.
I don't have a licence and don't have time to learn how to properly use it. I've been modeling in blender for years and changing to other software with so few time is very difficult.
@@ELECTRONOOBS You can read the policy but i don't think you have to buy it as long as you don't use it commercial. Also it is really a game changer. I'm really impressed that you came soo far only using blender.
Awesome attempts and good explanations. Although I am a bit afraid of the forces which will be applied to the 3D-printed resin-parts, it looks very cool.
A few other channels I subscribe to are reporting the same problem. I suspect part of the problem is the new subscribers page layout with the overly large thumbnails which limits how many videos you can see per page in the subscriptions page.
that's so sad to hear but come to think of it I do have observed that TH-cam is not suggesting or even giving any update onto u=your channel as well as the other inventors but I fell Ur content to be awesome
The problem is also that I have the feeling that the population is getting dumber and quality content is ignored for quick fun dumb videos. You can see this in the streaming services as well. Seeing the 99.99% of the content out there, I am not sure if I am still part of this planet anymore. I enjoy your videos, will be looking for them in my subs page. Sadly, I don't know many more people, who would be as interested as I am. I personally, wouldn't mind something quick and easy like this one. Instead of spending hours of video editing, if you can find another source of income to see how the channel goes, it might be wiser. Good luck!

no worries he uses servomotor instead of mechanical linkage it's gonna be tweaked easily via software eh
Thanks for the tip. Yeah i might have placed the control in the wrong direction in the video...
@@ELECTRONOOBSI figured you may have just been simplifying the concept. But I wanted to mention it if you weren't aware. I flew helos for 8 years 🙂👍
@@mcorrive12 any of those helis was 3D printed? :)))
@@ELECTRONOOBS LOL, no, Sikorsky hadnt adopted 3D printing yet! 😄
As if did not have to many flying toys as it is. Now u got me printing a new one 😂

That explanation of the swashplate and back rotor was brilliant!
Amazing engineering!!
Love it 🎉
It was amazing explanation i always wondered how does helicopter move from its position
23:52 it's changing bro I just got it recommended and TH-cam just tests for some time don't worry. By the way amazing explanation ❤
Wow, such a difficult project is designed and explained so easily!
I'm sure it will fly but I'm not sure how durable it will be. You can only do so much with resin plastics but there's new compounds coming out all the time to address these limits.
Amazing Project. The design of rotor assembly should be interesting
Love it. Great work. Best of the best my friend. 👌👌👌
This looks like it will be very interesting when done.
Nice swasholate. And it’ll be a collective pitch so you’ll be able to fly inverted :) I may have to make one myself!
Nice piece of work, in there! Thank you!
One of the best channel on youtube for this types of content and learning i will always supports you
Love from india
very informative video.
Wow, that thing has a prop diameter of four bananas.
Looking forward to the next video, and to see if the resin can handle the forces.
Love your channel - but I think you are right with your opinion
I think making the swash plate a little beefier could help; probably didn't have enough clearance when inserting the threads. you can try your luck with small wood screws as well, as they don't require thread inserts
