[@bobbaeyens4537]

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.

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.

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.

@@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]

@@seemlesslies what drives up the cost?

[@seemlesslies]

@@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.

[@marlinmixon3004]

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.

[@archygrey9093]

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.

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.

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!

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.

[@lamawithonel]

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?

[@kf4293]

If I remember correctly, the Osprey replacement is to have body mounted motors, driving rotors by shafts. Not sure if you could do that, but you wouldn't have motor weight out there, only rotors if you did. Fascinating project, so I subscribed to watch.

[@pannegoleyn9734]

I wonder how the roll stability would be with the motors inboard, though? Having the weight out at the wingtips gives a larger moment of inertia on that axis, which might (or might not!) be advantageous in wind

Huge congratulations on reaching 1 million subscribers. It’s well deserved, you’re one of the most entertaining creators on KZbin.

[@CartoType]

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.

[@breadgonebad3727]

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 KZbin 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.

[@oscar-bc9yk]

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?

[@oystercatcher943]

Fascinating, and such attention to detail, especially the 3D printing of the wing. It shows that 3D printing isn't magic and need some very clever problem solving.

[@coati4139]

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

[@finchesgalore2935]

Best KZbinr ever. Keep going strong💪

[@BJackIce324]

Great Video! I like three things best about your videos: 1) You don't do shortcuts - if problems occure you look for the cause and solve them. 2) You always do the math and give a detailed explanation. 3) One can see that you have fun in the process! Keep it up :)

[@TheFlavioOliva]

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?

[@maryalison1321]

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….🌹🌹🌹🌹

[@fernandograu6677]

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.

[@coasterairtime]

The quality of those 3D prints amazes me. We have come a long way with this technology

[@jadams3427]

You are a brilliant engineer. I don't have time to watch these videos, but I cannot escape ! Fantastic stuff !

[@tlreclipse1126]

Fantastic, I imagine this is what first flight was like trial error, optimization and watching this was impressive!

[@LearnEverythingAboutDesign]

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!

[@x-Dillon-x]

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

[@captainfalcon1120]

Its very impressive how much work went into making this VTOL and video to boot.

[@08joyal]

Every visit to your channel is really worth it. Your engineering decisions and the way you explain it is really awesome. Congratulations for 1m

[@p.r.5628]

You are magnific! Your skills are Top Notch, no doubt. Model builder, printer, programmer...and a skilled pilot.

[@beest_]

It's a pleasure watching you grow and be impressed by your work. All the best from Canada.

[@rezadavachi4213]

Amazing video. I think using cam follower instead of spur gears makes its response more faster and smoother by eleminating gears mesh.

[@some_random_wallaby]

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.

[@dznr1618]

Solid project, with great decisions on materials, geometry, and controls. Well done, and thanks so much for sharing the work.

[@hollytour]

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

[@blackseabrew]

Thanks for the info on how to design/print the wing. I just bought my first 3D printer. Actually I bought a resign printer 6 years ago but sent it back after learning about produced fumes that would have caused problems for my step-mom.

[@MrSychnant]

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 !

[@new.handle]

Great design and analytics of the problems. What I would suggest is a small support legs underneath motors to stop sinking of the wing once it lands. This way you prevent unwanted contact blades vs ground/grass.

[@808GT]

Been around since V1 and its lovely to see the evolution and progression of your designs and skills.

[@ronaldobrien211]

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!

[@md.labibarefinbari7781]

Hi @Tom, Love your work and the way you explain the details! I have thought about the dual servos. Using one servo in the middle with the same gear set up with the connective pole and the servos fixed with the connective pole. This will reduce weight, will consume less power, and reduce the chances of failure.

[@ericensley2427]

I love how you used the tilt rotor to reduce the number of parts and weight. In forward flight I was thinking you would use the torque from the props to turn, like in a drone, but using the tilt rotor was way better.
