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!!
Yeah, I kind of find a lot of interest in how turbojet vtol works, like the AV-8 or the F-35
@@StrikeEagIe Yeah, the F35 with the lift fan is one of my favorites.
The minute the video startet I had the urge to comment to let Tom know about dRehmFlight. Well, turns out he figured it out himself :D

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. 👍
RC lock-picking when
A wild LPL appears!
Wow. The cross over we all need.
Can you pick a lock via remote control? Uh, some crossover here for sure
Bro. Im commenting for clout and cant deny.
I love how you took the limitations of the PLA and created that really cool interior wing structure!
based off a thorough understanding of the problem, the solution was mind blowingly creative.
As a private helicopter pilot , I truly respect your knowledge and engineering . I totally enjoyed this video. Ty
The animation segment at 10:56 -12:59 was actually incredible.
I'm curious to know what software he use for that?
@@alexandrevaliquette1941 I *think* in the past he's had a little segment about it - maybe it was in one of the air-powered motor ones. I also *think* I remember it being Fusion 360 for the modelling and then Blender for the rendering.
There is NOTHING in this video that is not incredible.
Really cool project, and congrats on 1 million!
Yo didnt think id see you here lol
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!!!
WHY DO I SEE MULTIPLE UA-camRS IN THIS CHANNEL
wooouwed
I am amazed by how smooth the transition from hover to plane mode is. The final product looks way too good for a DIY build! :O
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. If you don’t mind can we be friends? Thanks God bless you….🌹🌹🌹🌹

@@rusinsr how are you doing
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!
The design of the print for the wings is simply amazing. The ingenuity on this channel is rivaled only by few on this platform. Your channel is a hidden gem
It's not hidden. He has 1M subscribers. However it is a gem.
@@mitchellsteindler 1M is sadly not as much nowadays.
yeah id love to se a tutorial on how to make something like this, i dont understand how the supports were added
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 dude is a living legend in model aircraft
I see you ever time I look in the mirror, what gives?
@@android61242 I thought I was hiding so well, but you can see me?
100%
@@greatestevar It's not my account, I was attempting a joke.
@@anon_y_mousse At least you nailed the landing..
Wow, this is some incredible engineering. You have a gift for explaining your design decisions.
I have followed your progress for a while, and I must say I am impressed with the work done and the formidable results. This last light-flyer is absolutely gorgeous! You really inspire with your videos.
That tilt mechanism is clean! Very cool to see all of the iterations.
Huh, you also noticed
Ha! All my favorite creators are in here!
That wing design seems so utterly satisfying. So precise and light and what a perfect use of a 3d printer and its capabilities.
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.
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.
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'd love to see how you designed those wings as one continuous line, really smart way to get rid of the oozing problem!
This please! I would love to see your design process.
Yeah!! Please
Would love to see this also!
The wings had me amazed. Suck a sick design and concept
Agree! Please make a video on continuous line printing optimization!
I love it when the form of an object is decided by its function and it looks very pleasing.
Congratulations on your deserved success
yes, this is an engineers build.
I wonder how much C4 they can carry
And some cod player hearing "vtol inbound"
“There's an old saying in the aviation industry that if an aeroplane looks right, it'll fly right,”
@@stevemadak6255 How do you explain the PL-12 AirTruk which flew quite wonderfully apparently? ;-)
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 👍👍
This is by far my favourite one of your projects! Absolutely amazing!
Congrats on the Million Subs Tom!
Be aware mate, real Tom will never ask to cover the shipping fee. Be careful plenty of scammers out there
Hi integza
I had had a couple of VTOL AirHogs planes. In fact that's the first plane I flew. Had a lot of fun modifying it later. Good memories
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
Congrats on the subscribers Tom. Well deserved for all the hard labour you put in. Your new design looks awesome, sellable even!
Holy cow, that plane is beautiful Tom! This is the first DIY RC project where I'm seriously considering copying it. The wings look super awesome and I really like your printing approach with LW-PLA. For braking you could try to use opposing forces with elevator and rotor tilt (rotors tilt backwards but elevator pushes down).
It might make sense to put some foil on the wing after printing, since I'd imagine the channels making an aerodynamic difference (should be tested). The foil could also be reflective to combat the heat problem.
@notfiveo Not needed with two lift rotors, even on a pure helicopter.
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 !
Thanks a million for your explanation and commitment. You're an example on how to spend free time and learn so much by experiment. You really get the feel for it. Looking forward to your next story.
Solid project, with great decisions on materials, geometry, and controls. Well done, and thanks so much for sharing the work.
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.

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.
The way you describe it makes it seem like it would be really fun if only you could be facing forward.
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?
@@johndododoe1411 peace time, so no bullets.
Wow, the engineering and design behind this project are exceptional. So cool to see your skills develop over the past couple years.
Congrats Tom, you deserve many millions of subscribers in my opinion. Always a learning experience and a pleasure to see your creativity and engineering prowess. Well done.
10:13 I want a slicer that does this sort of thing automatically. Vase-mode is awesome, and as you have shown here, it can be used to make infill and more solid designs using a continuous extrusion. Great stuff!
Where is ender 3000 part 2:(?
@@wenn1215 I've got something in the works. Really cool system w/ special extruder, heater, and nozzles coming in... and a 5 kg spool of filament 😉
@@NathanBuildsRobots Nice:) i will stay tuned, btw have you looked into pellet extruders? They seam to be able to extrude higher volumes.
Cura can already do combing, which is moving to the next line to print without lifting the print head. Stringing might still be a bit annoying, but combing and coasting are both quite good for reducing stringing. And on a functional print like this, cleaning up some extra stringing is usually no big deal.
@@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.
When in flight your final design looks strong, yet graceful like a dragonfly. Marvelous!
So incredibly satisfying to see a video demonstrating the intersection of art, engineering, mathematics, elegance, and nature all together in a BEAUTIFUL combination!
It's a pleasure watching you grow and be impressed by your work. All the best from Canada.
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.
@@rh3ttj you are
If you ever go near Mildenhall, they occasionally fly there.
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.
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.
Tom your success is well deserved, awesome video! An impressive blend of creativity and well thought out engineering.
What a gerat job! Thank you for your passion, and deep interest which turn out to this fantastic video!
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
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
Awesome construction and design! Thank you for sharing it, and not only the finished product!
Nicely done, Tom. Very Interesting to watch your very sound development path. Thanks for sharing.
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.
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.
Awesome project and very inspiring! I love your methodology of hypothesis, implementation, testing and reiteration. Well done!!
That is a great flyer: much better and simpler than many commercial vtols I've seen. Congratulations
!
Simply brilliant, Tom. The simplicity hides the time and effort it must have taken to design, make and refine this aircraft. Not to forget the time and effort to produce such quality animations and video.
Very impressive engineering work, I salute you! Also those visuals where just spot on!
You are a brilliant engineer. I don't have time to watch these videos, but I cannot escape ! Fantastic stuff !
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.
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.
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 is a GORGEOUS machine. I love watching it fly!
Man, you really are brilliant in clusters of fields necessary to do these things. Congrats on the work!
Tom, you're an inspiration. I've been working on 3D printed multi-rotors, VTOLs and Flying Wings for a couple of years now and your earlier videos were good encouragment.
All your videos have been great.
wow, as an aerospace engineering senior starting my senior design project this semester, YOU MAKE IT LOOK SO EASY!
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.
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.
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!
you are really genius!
The way you designed the wing and then tested by just putting them in the sun was just simply genius.
Been around since V1 and its lovely to see the evolution and progression of your designs and skills.
Awesome work Tom! Thanks very much for this - totally inspiring!! Amazing work with Nicholas Rehm's DrehmFlight code. And all your skills. And determination!
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
This project is great thanks for sharing how you did it
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 !
Love the "vase mode" wing design! Great job in the engineering. :)
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
@@jordanhitman 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.
Lots of great stuff packed in one video. I like how you've put the new foaming stuff to good use, and seeing the temperature comparisons was eye opening. I didn't think colour made that much difference.
Congratz on the million! Love this project! I've been eyeing making one of these for a while, this one is seriously tempting ...
That wing print is amazing! Awesome idea on the continuous print !
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.
Super inspiring stuff. I am slowly gathering supplies to tinker in such ways. Thanks for doing what you do!!!
Always enjoy your videos Tom, thatnk-you for showing the theory and practical aspects, lots to learn.
This version flies very well, both in hover, as in normal flight. Congrats on persevering with this.
Looks like really smooth flight in forward mode! I love how a well made dihedral turns
another outstanding project and video from tom stanton. excellent work!!
I love VTOL aircraft! Thanks for the great video and really good job on the design and materials selection, the completed assembly is really good looking!
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.
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.
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!
Every visit to your channel is really worth it.
Your engineering decisions and the way you explain it is really awesome. Congratulations for 1m
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 way you designed the wing and then tested by just putting them in the sun was just simply genius.
Great video - including so really useful resources. Was surprised to see how much color affected warpage of the wings. Keep up the great work!
Very cool, love the simplicity and depth the design
Congratulations Tom on the 1M subscribers, that’s amazing.
This version of the VTOL is also amazing, you should look to sell these as a kit, they would fly (pun intended) out of the door. I’d buy one for sure.
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?
Wow, great work! It's amazing how graceful it looks switching modes!
Its very impressive how much work went into making this VTOL and video to boot.
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
Odd. I see a notification saying you uploaded this five seconds ago, and yet I click and there is a comment that is 39 seconds old. Hmmm...
Hey🎉🥳👏🎈🎁🥂🎊🥳🎉🍾Congratulations! That is well deserved! And, being able to follow your projects through their ups and downs is a great pleasure! I was delighted when I saw, there is another VTOL video. I love this project!
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.
Amazing video! As a former student of engineering, I'd love to see a full shell for it, and maybe some increased modularity for the wings!
Maybe you could do small snap connection points, though that might increase the weight, it would mean less need for glue and allow you to replace individual damaged segments, or to add a flap segment without remaking the wings every time, or even hardpoints for mounting extra batteries or something cool like that!
One thing I'd really love to see with the shell is if you can mess with RADAR to see if you could make a stealth shell, similar to the F117's technology.
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.
Thankyou Tom for a excellent Video ! Great Job on the Build and RC equipment.😎
congrats on 1mil
Wow! I am more than thoroughly impressed by your technical knowledge and skill. I subscribed to your channel. Please continue to share.
The idea which pops into my head to stop forward flight in preparation for a transition to hover is to program the controller to tilt the motors beyond vertical to an angled back position and then automatically rotate back to vertical. This transition could use input from the accelerometer to detect when reverse acceleration had been applied long enough zero out axial airspeed.
Not sure if the V22 does this, but I know the Harrier is/was able to rotate the nozzles slightly backwards beyond the vertical.
