So excited to be a small part of your VTOL journey as a fellow VTOL addict myself, and to help you celebrate such a huge milestone. Congrats on 1M Tom!!
What a great video to usher in the one million sub milestone. Your success is well-deserved. I always look forward to your creativity, and just-technical-enough explanations. Keep it up. 👍

Look at 18:47 what a coincidence that a huge airliner is in the sky behind your plane, I LOVE that contrast of the tried and developed vs the experimental creativity that started it all
This project has all the hallmarks of great engineering: a simplified design with very few moving parts, relying on well-known and reliable components but used in a clever way. Amazing work!
If BDA approves, Tom, you've got something! It would only have been a hair better if instead of 3D printed and carbon fiber you used WEWD! Congats Tom!!!
The design is extraordinary, my jaw dropped when I saw it. Would love to see how he pulled that off. But Im not convinced about the concept of 3d printed wings, as Im fairly sure a EPS foam wing would be both lighter and stronger (and cheaper and much faster). Cutting one with the right profile is quite easy for a wing like that with no tips, no twist, and just one airfoil. Or you could CNC it if you wanted any of those. And if you want even lighter, just use traditional RC glider construction methods, like spars and foil. In short, the wing I think is a perfect misuse of 3d printer capabilities.
Whenever you post a new video, I know I can just sit, put it in full screen, and do nothing else than dive into your projects. I know I'll learn one or 2 things on 3D printing optimization, be impressed by clever and compact designs, and feel enlightened by your engineering approach of solving and improving the product at the same time. Your way of mixing fun ideas with great "storytelling" in the origin and the conclusion of your design is just incredible, keep this going !
Another great one to add to your collection. Not many people can pull off 20-minute videos packed with the amount of information, entertainment, and enjoyment like you do. A heartfelt congratulations on hitting the 1M mark. You should liquefy the gold play button they send you and use it to coat the mirror on your first homemade space telescope!
I like how much you have put into the explanation and visualization of the VTOL control mechanics. Gives full picture on what is happening and why the designs are what they are to make it happen.
Hi Rusins I hope my comment didn't sound as a form of privacy invasion your comment tells of a wonderful man with a beautiful heart which led me to comment I don't normally write in the comment section but I think you deserve this complement.

From an engineering perspective, I think this is the coolest thing you’ve done. Bravo. I’m not American, so I’ve only seen the V-22 twice. Once at an airport in Poland. The second crossing over the bridge back to Canada at Niagara Falls. I remember it sounded like a helicopter, then made a weird loud noise while I presume it transitioned and flew off sounding like an airplane. The transition noise sounded like when a drone or RC helicopter is tilted heavily, but much louder if course. Sounds like chopping air to me. I’m sure regular helicopters make that noise too but I’ve never heard it.
I think you may be overestimating how common they are, I'm American and I don't recall ever seeing a V-22 in person. Or maybe I've just been living under a rock.
I thought they were phased out years ago due to the occasional serious failure during tranistion caused some horrific crashes. I saw two flying around London when the orange dude came to town, but prior to that I think I have only seen them at an airshow
The osprey is extremely loud (and inefficient) in hover mode due low pitch and high rpm but super silent (and efficient) in airplane mode since it can reduce propeller speed and increase pitch.

The Osprey is one of the few aerial vehicles I’ve ridden within (as a passenger) in the US Marine Corps. Never in my life have I experienced harder G-forces! Such broad, dropping turns, dude!! The seats are in the rearward facing portion of the fuselage (backs strapped to the wall, facing another group of people on the opposite wall) with a partially open tail. There are a lot of things I would do again, no issue, but being slung around in one of those things was one of the most disorienting and blood-pressure reducing things I’ve ever done. No thanks ✌🏻😅 Ospreys are cool. They make you feel like a pancake in the clothes dryer, though.
in all seriousness those things are deathtraps. I've ridden ospreys, '53, '46, blackhawks... I'd rather clean all the bathrooms in Grand Central Station *WITH MY TONGUE* than ever get on an Osprey again.
Seems I remember looking up right after one of the those "high G turns" and seeing the crew chief of the CH-46 I was on, yucking it up cause they had F'd with the "hard core" jarheads. So there is the never missing streak of mischievous sadism found in every USMC marine.
@@saguarotreker Do those high G turns equate to efficient dodging of enemy actions in a live scenario, or are they just a side effect of standard maneuvers at home base?

@@wenn1215 I have seen the Dr D-Flo video. Pellets are much cheaper than filament, so it is tempting. It would be hilarious to put a massive pellet extruder on an Ender 3, I'll reach out to massive dimension and see if they are interested in a collab.
This machine is so attractive, that I am building one myself. The best part is how you solve the problems, and I think it's the beauty of engineering thinking. Great Job.
I’ve been watching your videos for a few years now Tom and I am always blown away by your knowledge and imagination. I find your way of delivering each project video very captivating. Well done on your million subscribers millstone.
Very deserving of the the one million, Tom - congratulations! I really enjoy the complete yet succinct narration of your journey through the design, testing, and mods- a really compact lesson in R&D. I look forward to your next video.
So incredibly satisfying to see a video demonstrating the intersection of art, engineering, mathematics, elegance, and nature all together in a BEAUTIFUL combination!
I looked at the code and it is surprising how accessible and editable this imagined 'magic' has become. Like the actual flight-control math goes over my head but the functionality and modification options are quite understandable.
This looks really high-end and professional, well done.! The slow mo shots toward the end are great. Makes me wonder what practical applications something like this could have, that might out-compete a standard drone. Some kind of surveying / observation platform perhaps.
This design would be fantastic for the various companies who are getting into drone delivery of goods. Most are using planes as opposed to multi rotors for their higher efficiency, but at the cost of complicated launching and landing systems.
Would also be great for LIDAR applications. Couple it Skydios software, cameras, LIDAR, larger structures or plots of land could be surveyed. Add solar panels to the fuselage and wings to lengthen flight time.
@@motosk8er2 planes will never be able to fulfill the weight requirements for anything outside of maybe 1-2 lbs and smaller in size. My capstone was literally designing a vtol aircraft to fly 1-2 hours with a 2.5-5lb payload. It's just not cost effective in most situations.
@@JosephProsnitz1 It's really not cost it's physics. They weight requirements mean that the planes just honestly need to be bigger, and at that point it's just cheaper just to do standard delivery. The problem with aircraft in general that weight ratios are the biggest factor to overcome. The heavier and larger your payload the more power you need. However, when you're electric you carry your batteries as weight the entire flight. This is also ignoring the total nightmare of regulations due to drone delivery and just how impractical it is. My project was centered around weather recording. The weather center could only get 30 mins of drone flight time. We were tasked with creating a Vtol craft for them so that they could fly 1-2 hours with around 2.5-5lbs of monitoring equipment. They wanted the ability to take off without human control or the need of a skilled thrower/pilot. It was going to be controlled by uhm a software I forget the name of it, but that you can just entirely GPS to fly the entire craft. We didn't get to finish due to covid. Another big issue with VTOL aircraft is getting the most efficient prop and motors for all systems, but by doing so you pretty much end up with a prop that is unable to actually take off and needs the quads assisting it during takeoff.
I happened upon this video purely by accident and I am thrilled I did. As an Osprey pilot, I must say that you have done a fantastic job. Very impressive!
Very nice Tom! For optimum efficiency, I suggest reversing the rotation of your motors so that they turn the same direction as the Osprey's. The reasoning goes like this: if the right/starboard motor is turning clockwise as viewed from the front it will enhance the inevitable wingtip vortex which = bad. If it turns counter or anticlockwise it will diminish the wingtip vortex and lead to an efficiency gain. Maybe not too much efficiency effect either way, but probably not a hard change to make. And might be worth a video investigation as a bonus.
Another channel did a video on this exact topic, and I think it's worth a watch. I would love to see Tom's take on it though, of course "Can Wingtip Motors Improve Aircraft Efficiency? RCTestFlight Solar Collaboration Part 1" by Think Flight
I think someone posted onto rctestflights video another aero physicist basically saying you cant actually get any benefit out of it if you do a proper flux analysis. But I'm not willing to say I actually understood the video, the explanation, or even the conclusion correctly!
The ospreys are absolutely incredible and seeing how much work has gone into just an rc vtol, I can’t imagine how much work and engineering goes into the real thing
@@Brostab.x pretty much goes like this, everyone who doesn't work on them. "wow that's amazing" etc. People who work on them "oh no not another engine change!"
Osprey was a cool concept then the pentagon got involved like with the Bradley and many other programs. Now we have a non-pressurized pig, no native armaments, that can't handle power shift if one engine unspools, burns the deck if VTOL from a ship, disk loading is so high it destroys everything in a 300' radius and can't auto-rotate. Not to mention it has the highest accident/death rate per hour of any aircraft in the military. And costs $63,000/hour to fly. The V22 program should have stopped before it got started.
I really enjoy every one of your videos, they always manage to “tickle my intelligence”. 1M subs are well deserved. Btw, the 3D wing sections are a thing of beauty.
I found your channel YEARS ago from the corridor ebike video. I can't believe you hit 1mil already! Congrats! Edit: Loving the new animations in the videos!
Excellent project and very inspiring! Someone has probably already mentioned it however i found aqueous based polyurethane resin stabilises the LW-PLA with only moderate weight gain ~20%. Light fiberglass cloth makes it even better (Tested in full Australian summer sun!). I can't wait to see your next VTOL iteration.
I absolutely love the osprey as well, had a illustrated book with it when younger and it was the coolest thing in the book by miles Amazing what you've done, so impressed
I would be excited to see someone make a true rc Osprey, with fully articulated rotorheads. It's essentially two full helicopter swashplates. Difficult, but, with your experience, I think you could pull it off.
Looks like a Dragonfly robotic insect ...very cool ! love the simplicity and form of function just like nature would create . The best vid I think you've ever made .
the wing structure and printing solutions are a masterclass! and yes, the white plastic a very sensible solution for the warping. congrats for the 1,000,000 subscribers mark 7 months ago, growing up to 1,120,000 as I watch this in march 2023.
I had the rare privilege of walking outside my house one morning and hearing a strange plane engine noise, one I had never ever heard before, at least not in person. It sounded sort of like a regular prop plane, but more "booming", if that makes sense. Anyway, I located the area of the sky the noise was coming from, and I saw my first VTOL! The Osprey! They were possibly doing manuevers/training or just seeing she flew properly. But what a sight to behold, you see an airplane outline in the sky and it certainly has the profile and flight path/characteristics of a plane... but... it has two props in a vertical orientation. Actually, while watching, I couldnt believe I had the chance to see the pilot shifting the plane from vertical to horizontal thrust!!!! Remarkable. For anyone who is a plane enthusiast, I strongly suggest finding an airshow that has an Osprey flying at it, and going to go see it, in person. In person, seeing and hearing it... is an experience!
When I first subscribed, I was absolutely impressed. I never guessed you would expand to such intensity. I can see you are so much better now than some years ago. I can only guess the level of ingenuity you will be at in 5 or 10 years! Anti gravity designs, I would have to imagine.
I always thought I had a pretty good knowledge, both mechanical and electrical, but it pales into insignificance with your efforts. I find your videos both entertaining and fascinating, and that someone of your young age has such a brilliant mind. Hearty congrats on your 1 million subs Tom, and keep up with the excellent experiments and inventions.
Well done Tom you have by far exceeded everyone's expectations. You are the same age of my son and you two have so much in common. Loved your video and congrats on the 1M Cheers!
Congratulations with reaching a million! Been following you for years and really love the way you have shaped your channel. One of my favourite makers on UA-cam and your explanations always go just enough in depth for me to follow. Keep up the good work! PS: I'm really hoping for a revisit of the trebuchet. One of the most impressive builds I've ever seen.
12:09 from what i know, if you set the props to spin the opposite ways, it will be more efficient, since it counteracts wing tip vertices. Edit: I think they just spun the wrong way in the digital model, though it is hard to tell on the actual VTOL
My Dad was a test pilot in the USAF. In 1964 he became deputy director of Research and Development for the USAF assigned to the Pentagon. Dad was a HUGE advocate for STOL and VSTOL technology. Sadly, the now disgraced Secretary of Defense, Robert MacNamara wanted to build billion dollar bases all around the world. This rift led to dad’s early retirement. We had models and drawings of VSTOL designs in dad’s office at home.
What a fucking dumbass. MacNamara forced our country to basically become military welfare for litterally everyone. While its a good decision back then, its beyond stupid now. We have no place in other countries. At best, we should only be setting up "Amazon Warehouses" type bases. Not whatever the fuck this is.
@@honkhonk8009 while I don’t totally understand your reply MacNamara was a truly evil man. As was the administration (s) responsible for Vietnam. Immediately After that war I spent several years with an American oil company. During that time it became obvious that the war was all about the massive oil and gas field in the sea between Vietnam and Borneo. The Da Nang harbor was built so that after the war it was quickly and easily converted to a massive oil and gas shipping port. And that is what it is today. 65,000 young Americans and millions of Vietnamese slaughtered for oil rights. A black mark in the history of America. Note the lack of profanity in my note.
hello Tom. Interesting channel you have there. I have had an idea since I was a child for a possible flying craft that I just never had the time or resources to experiment with. I'm old now, so I doubt I ever will. With the new technology of lithium batteries and 3D printing, it seems like there could be a way to test my theory. However the cost of doing the tests in time and money are not an option for me now. In a nut shell, the idea is to use compressed air to propel a frisbee type craft to keep it spinning and therefore flying. it would need jets positioned on the outside outer edge to spin the craft, and the compressor hanging on the underside center so as to be able to shift the center of gravity for forward movement, using servos. As a kid I was always fascinated how a frisbee would hover and descend as it lost momentum. So I assumed if the momentum could be maintained or increased, the frisbee would rise or at least hover. I have no knowledge or expertise of aerodynamics and this is quite possibly a childhood fantasy. Anyway, I'll keep watching your videos. They are quite fascinating. Thank you.
i was thinking painting your wings or taping them with aluminum tape to give it some thermal resistance could be beneficial. it may also smoothen the surface and act as a sort of glue. Yes the weight will increase but as light as your craft is, at this level it would still function until you find a better solution or stronger more glass fibery pla :)
How did you make your parts vase mode compatable? Is there a tool or do you add the little slots manualy in CAD. If so what are the best slot widths to use?
Have you considered using the spar shafts for independent VTOL rotation, with two servos in the fuselage? I'm guessing the reduction in moment of inertia of the entire body would more than compensate for the added moment of inertia of the rotating shafts, although I don't know if the added weight required to support shafts and keep them from binding would negate those effects. What are your thoughts on this?
It's really just incredible what a single person can do today..., design and build an RC VTOL, including 3D printing a wing (!), then record and edit video and publish it..., it's just incredible.
hello, really nice video. thank you for all the information you share with us. one question: could you tell us what is the weight difference (more or less) between a normal rc airplane wing and a 3d printed?

Congrats on the big 1 million milestone, well deserved ! Been watching your channel for quite a while, always learn something new. This video was one of the best to date.
That's a fantastic build, well beyond my skill set. Congratulations! My interest is in building an R/C model. That's what brought me to your channel. At 18:58 when you say the airplane wouldn't be able to turn if a motor failed. But if you had ailerons/flaperons, you could try and glide to a landing, the emergency procedure in an Osprey if a motor fails. Which brings up flaperons. No, don't use them on a glided controlled crash/landing. The Osprey uses them to slow down for the conversion to the VTOL mode.
The video was able to explain in a comprehensive yet simple way the various problems encountered ,a truly scientific approach.. I was very impressed, have liked and subscribed !

@@wenn1215 I have seen the Dr D-Flo video. Pellets are much cheaper than filament, so it is tempting.
It would be hilarious to put a massive pellet extruder on an Ender 3, I'll reach out to massive dimension and see if they are interested in a collab.
This machine is so attractive, that I am building one myself.
The best part is how you solve the problems, and I think it's the beauty of engineering thinking.
Great Job.
Very impressive engineering work, I salute you! Also those visuals where just spot on!
That printed wing pattern is beautiful, and so functional too!
I wish he would post the files, it would take me ages to reverse engineer something nearly as good as that.

I’ve been watching your videos for a few years now Tom and I am always blown away by your knowledge and imagination. I find your way of delivering each project video very captivating. Well done on your million subscribers millstone.
I feel like this would be nice to sell as a kit, i can see this being genuinely useful!
If he sells this, I would buy one.
He'd give other youtubers with their mugs and t-shirts imposter's syndrome lol
looks affordable too
Just make it?
@@InfiltrateIndustries oh sure i'll just buy a 3d printer to make a single RC plane
Very deserving of the the one million, Tom - congratulations! I really enjoy the complete yet succinct narration of your journey through the design, testing, and mods- a really compact lesson in R&D. I look forward to your next video.
So incredibly satisfying to see a video demonstrating the intersection of art, engineering, mathematics, elegance, and nature all together in a BEAUTIFUL combination!
I looked at the code and it is surprising how accessible and editable this imagined 'magic' has become. Like the actual flight-control math goes over my head but the functionality and modification options are quite understandable.
wow, as an aerospace engineering senior starting my senior design project this semester, YOU MAKE IT LOOK SO EASY!
The way you designed the wing and then tested by just putting them in the sun was just simply genius.
This looks really high-end and professional, well done.! The slow mo shots toward the end are great. Makes me wonder what practical applications something like this could have, that might out-compete a standard drone. Some kind of surveying / observation platform perhaps.
This design would be fantastic for the various companies who are getting into drone delivery of goods. Most are using planes as opposed to multi rotors for their higher efficiency, but at the cost of complicated launching and landing systems.
Would also be great for LIDAR applications. Couple it Skydios software, cameras, LIDAR, larger structures or plots of land could be surveyed.
Add solar panels to the fuselage and wings to lengthen flight time.
@@motosk8er2 planes will never be able to fulfill the weight requirements for anything outside of maybe 1-2 lbs and smaller in size.
My capstone was literally designing a vtol aircraft to fly 1-2 hours with a 2.5-5lb payload.
It's just not cost effective in most situations.
@@seemlesslies what drives up the cost?
@@JosephProsnitz1 It's really not cost it's physics. They weight requirements mean that the planes just honestly need to be bigger, and at that point it's just cheaper just to do standard delivery.
The problem with aircraft in general that weight ratios are the biggest factor to overcome. The heavier and larger your payload the more power you need. However, when you're electric you carry your batteries as weight the entire flight.
This is also ignoring the total nightmare of regulations due to drone delivery and just how impractical it is.
My project was centered around weather recording. The weather center could only get 30 mins of drone flight time. We were tasked with creating a Vtol craft for them so that they could fly 1-2 hours with around 2.5-5lbs of monitoring equipment.
They wanted the ability to take off without human control or the need of a skilled thrower/pilot. It was going to be controlled by uhm a software I forget the name of it, but that you can just entirely GPS to fly the entire craft. We didn't get to finish due to covid.
Another big issue with VTOL aircraft is getting the most efficient prop and motors for all systems, but by doing so you pretty much end up with a prop that is unable to actually take off and needs the quads assisting it during takeoff.
19:19 I think it was heavy because of the weights you put on the wings. You could easily remove about 10 lbs by taking off those weights.
:P
I happened upon this video purely by accident and I am thrilled I did. As an Osprey pilot, I must say that you have done a fantastic job. Very impressive!
Very nice Tom! For optimum efficiency, I suggest reversing the rotation of your motors so that they turn the same direction as the Osprey's. The reasoning goes like this: if the right/starboard motor is turning clockwise as viewed from the front it will enhance the inevitable wingtip vortex which = bad. If it turns counter or anticlockwise it will diminish the wingtip vortex and lead to an efficiency gain. Maybe not too much efficiency effect either way, but probably not a hard change to make. And might be worth a video investigation as a bonus.
That is actually a really smart idea
Another channel did a video on this exact topic, and I think it's worth a watch. I would love to see Tom's take on it though, of course
"Can Wingtip Motors Improve Aircraft Efficiency? RCTestFlight Solar Collaboration Part 1" by Think Flight
I think someone posted onto rctestflights video another aero physicist basically saying you cant actually get any benefit out of it if you do a proper flux analysis.
But I'm not willing to say I actually understood the video, the explanation, or even the conclusion correctly!
Love the "vase mode" wing design! Great job in the engineering. :)
That is a great flyer: much better and simpler than many commercial vtols I've seen. Congratulations
!
The ospreys are absolutely incredible and seeing how much work has gone into just an rc vtol, I can’t imagine how much work and engineering goes into the real thing
Let's just say they aren't cheap or easy. Freakin things break badder than Walter White.
Can confirm.
Half the time it goes as follows:
Bird flies > Bird breaks > We fix bird > Bird flies > Bird is broke worse than last time > Repeat
@@Brostab.x pretty much goes like this, everyone who doesn't work on them. "wow that's amazing" etc. People who work on them "oh no not another engine change!"
Osprey was a cool concept then the pentagon got involved like with the Bradley and many other programs. Now we have a non-pressurized pig, no native armaments, that can't handle power shift if one engine unspools, burns the deck if VTOL from a ship, disk loading is so high it destroys everything in a 300' radius and can't auto-rotate. Not to mention it has the highest accident/death rate per hour of any aircraft in the military. And costs $63,000/hour to fly. The V22 program should have stopped before it got started.
I really enjoy every one of your videos, they always manage to “tickle my intelligence”. 1M subs are well deserved. Btw, the 3D wing sections are a thing of beauty.
Be aware mate, real Tom will never ask to cover the shipping fee. Be careful plenty of scammers out there
I found your channel YEARS ago from the corridor ebike video. I can't believe you hit 1mil already! Congrats!
Edit: Loving the new animations in the videos!
Excellent project and very inspiring!
Someone has probably already mentioned it however i found aqueous based polyurethane resin stabilises the LW-PLA with only moderate weight gain ~20%. Light fiberglass cloth makes it even better (Tested in full Australian summer sun!).
I can't wait to see your next VTOL iteration.
I absolutely love the osprey as well, had a illustrated book with it when younger and it was the coolest thing in the book by miles
Amazing what you've done, so impressed
You are a brilliant engineer. I don't have time to watch these videos, but I cannot escape ! Fantastic stuff !
This is by far my favourite one of your projects! Absolutely amazing!
I would be excited to see someone make a true rc Osprey, with fully articulated rotorheads. It's essentially two full helicopter swashplates. Difficult, but, with your experience, I think you could pull it off.
This.
Je suis juste abasourdi par autant de compétences réunies en une seule personne. Chapeau bas.
Looks like a Dragonfly robotic insect ...very cool ! love the simplicity and form of function just like nature would create . The best vid I think you've ever made .
Huge congratulations on reaching 1 million subscribers. It’s well deserved, you’re one of the most entertaining creators on UA-cam.
the wing structure and printing solutions are a masterclass! and yes, the white plastic a very sensible solution for the warping. congrats for the 1,000,000 subscribers mark 7 months ago, growing up to 1,120,000 as I watch this in march 2023.
That wing print is amazing! Awesome idea on the continuous print !
I had the rare privilege of walking outside my house one morning and hearing a strange plane engine noise, one I had never ever heard before, at least not in person. It sounded sort of like a regular prop plane, but more "booming", if that makes sense. Anyway, I located the area of the sky the noise was coming from, and I saw my first VTOL! The Osprey! They were possibly doing manuevers/training or just seeing she flew properly. But what a sight to behold, you see an airplane outline in the sky and it certainly has the profile and flight path/characteristics of a plane... but... it has two props in a vertical orientation. Actually, while watching, I couldnt believe I had the chance to see the pilot shifting the plane from vertical to horizontal thrust!!!! Remarkable.
For anyone who is a plane enthusiast, I strongly suggest finding an airshow that has an Osprey flying at it, and going to go see it, in person. In person, seeing and hearing it... is an experience!
They are certainly a strange thing to see go overhead. Presumably the sound is a similar interference effect to a chinook helicopter?
what a brilliant solution for the lw pla. you're the best tom
This version flies very well, both in hover, as in normal flight. Congrats on persevering with this.
When I first subscribed, I was absolutely impressed. I never guessed you would expand to such intensity. I can see you are so much better now than some years ago. I can only guess the level of ingenuity you will be at in 5 or 10 years! Anti gravity designs, I would have to imagine.
I always thought I had a pretty good knowledge, both mechanical and electrical, but it pales into insignificance with your efforts. I find your videos both entertaining and fascinating, and that someone of your young age has such a brilliant mind. Hearty congrats on your 1 million subs Tom, and keep up with the excellent experiments and inventions.
Man what a GREAT design of the no support structure in the wings! I would love to know more about how that design was developed.
Looks like really smooth flight in forward mode! I love how a well made dihedral turns
Well done Tom you have by far exceeded everyone's expectations. You are the same age of my son and you two have so much in common. Loved your video and congrats on the 1M
Cheers!
Congratulations with reaching a million! Been following you for years and really love the way you have shaped your channel. One of my favourite makers on UA-cam and your explanations always go just enough in depth for me to follow. Keep up the good work!
PS: I'm really hoping for a revisit of the trebuchet. One of the most impressive builds I've ever seen.
Best UA-camr ever. Keep going strong💪
Marvellous project. Well done! I sometimes see an Osprey flying past our house in NW Herefordshire and it always makes me smile, despite the noise.
12:09 from what i know, if you set the props to spin the opposite ways, it will be more efficient, since it counteracts wing tip vertices.
Edit: I think they just spun the wrong way in the digital model, though it is hard to tell on the actual VTOL
Would this direction be the high point tips going outwards?
@@h8GW Yes
My Dad was a test pilot in the USAF. In 1964 he became deputy director of Research and Development for the USAF assigned to the Pentagon. Dad was a HUGE advocate for STOL and VSTOL technology. Sadly, the now disgraced Secretary of Defense, Robert MacNamara wanted to build billion dollar bases all around the world. This rift led to dad’s early retirement.
We had models and drawings of VSTOL designs in dad’s office at home.
What a fucking dumbass. MacNamara forced our country to basically become military welfare for litterally everyone.
While its a good decision back then, its beyond stupid now.
We have no place in other countries. At best, we should only be setting up "Amazon Warehouses" type bases. Not whatever the fuck this is.
@@honkhonk8009 while I don’t totally understand your reply MacNamara was a truly evil man. As was the administration (s) responsible for Vietnam. Immediately After that war I spent several years with an American oil company. During that time it became obvious that the war was all about the massive oil and gas field in the sea between Vietnam and Borneo. The Da Nang harbor was built so that after the war it was quickly and easily converted to a massive oil and gas shipping port. And that is what it is today. 65,000 young Americans and millions of Vietnamese slaughtered for oil rights. A black mark in the history of America.
Note the lack of profanity in my note.
Your dad is a really cool dude!
Fantastic, I imagine this is what first flight was like trial error, optimization and watching this was impressive!
hello Tom. Interesting channel you have there. I have had an idea since I was a child for a possible flying craft that I just never had the time or resources to experiment with. I'm old now, so I doubt I ever will. With the new technology of lithium batteries and 3D printing, it seems like there could be a way to test my theory. However the cost of doing the tests in time and money are not an option for me now. In a nut shell, the idea is to use compressed air to propel a frisbee type craft to keep it spinning and therefore flying. it would need jets positioned on the outside outer edge to spin the craft, and the compressor hanging on the underside center so as to be able to shift the center of gravity for forward movement, using servos. As a kid I was always fascinated how a frisbee would hover and descend as it lost momentum. So I assumed if the momentum could be maintained or increased, the frisbee would rise or at least hover. I have no knowledge or expertise of aerodynamics and this is quite possibly a childhood fantasy. Anyway, I'll keep watching your videos. They are quite fascinating. Thank you.
A powered Frisby would be a great project for Tom!
i was thinking painting your wings or taping them with aluminum tape to give it some thermal resistance could be beneficial. it may also smoothen the surface and act as a sort of glue. Yes the weight will increase but as light as your craft is, at this level it would still function until you find a better solution or stronger more glass fibery pla :)
Congrats Tom. You deserve the one million. Loved that design.
How did you make your parts vase mode compatable? Is there a tool or do you add the little slots manualy in CAD.
If so what are the best slot widths to use?
Have you considered using the spar shafts for independent VTOL rotation, with two servos in the fuselage? I'm guessing the reduction in moment of inertia of the entire body would more than compensate for the added moment of inertia of the rotating shafts, although I don't know if the added weight required to support shafts and keep them from binding would negate those effects. What are your thoughts on this?
It's really just incredible what a single person can do today..., design and build an RC VTOL, including 3D printing a wing (!), then record and edit video and publish it..., it's just incredible.
Hey Tom, Would you mind sharing all the hardware you use for this project? I'm really interested into building one on my own and improving it further
Cool design! I'd be interested to see how much power it draws traversing a certain distance to compare hover vs flight modes.
The quality of those 3D prints amazes me. We have come a long way with this technology
hello, really nice video. thank you for all the information you share with us. one question: could you tell us what is the weight difference (more or less) between a normal rc airplane wing and a 3d printed?
Hi Flavio I hope my comment didn't sound as a form of privacy invasion your comment tells of a wonderful man with a beautiful heart which led me to comment I don't normally write in the comment section but I think you deserve this complement. If you don’t mind can we be friends? Thanks God bless you….🌹🌹🌹🌹
You are magnific! Your skills are Top Notch, no doubt. Model builder, printer, programmer...and a skilled pilot.
It's a pleasure watching you grow and be impressed by your work. All the best from Canada.
Every visit to your channel is really worth it.
Your engineering decisions and the way you explain it is really awesome. Congratulations for 1m
i first stumbled across this channel for your VTOL series. but i sticked around for your very well explained and detailed projects that came along.
I learned alot of theoretical concepts and all workarounds to utilize such concepts for personal projects.
Thank you very much for amazing content and congratulations on your 1 million subscribers 👍👍
Future aerospace developments are in good hands when we have clever guys like you pushing the envelope with practical solutions to encountered problems. Excellent work and very informative video Thank you
For some reason youtube suggested this video to me today and even though i've never built a VTOL nor even flown an RC airplane I thought it was great! I thought the wing design was really clever preventing the nozzle from retracting. Nice work all around Tom!
Been flying RC and full size since 1978, you're a frickin genius.
this is the best thing i have seen in months. WELL PLAYED !
Mate, this was the first video of yours I’ve watched and I am truly blown away with your skills and capabilities. I watched the whole way through and was truly impressive.
It’s people like you who give me confidence in humanity to achieve amazing things for the future. Keep up the great work
Wow, the engineering and design behind this project are exceptional. So cool to see your skills develop over the past couple years.
Congrats on the big 1 million milestone, well deserved ! Been watching your channel for quite a while, always learn something new. This video was one of the best to date.
Looks like an educational video, I've learned more in 20 minutes than 5 years of school, keep it up!💪
That's a fantastic build, well beyond my skill set. Congratulations! My interest is in building an R/C model. That's what brought me to your channel. At 18:58 when you say the airplane wouldn't be able to turn if a motor failed. But if you had ailerons/flaperons, you could try and glide to a landing, the emergency procedure in an Osprey if a motor fails. Which brings up flaperons. No, don't use them on a glided controlled crash/landing. The Osprey uses them to slow down for the conversion to the VTOL mode.
Such a cool project, well done.
It's in depth videos like yours that thank heavens for UA-cam
By far my favourite UA-camr for many years, congratulations on your well deserved success Tom.
The video was able to explain in a comprehensive yet simple way the various problems encountered ,a truly scientific approach.. I was very impressed, have liked and subscribed !
