Optimising a VTOL 

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

@@anon_y_mousse It's an impressive and capable machine, but ugly af

@@slartibartfast2649 The F35? Do you have no taste my good sir, it is a work of beauty.

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.

based off a thorough understanding of the problem, the solution was mind blowingly creative.

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….🌹🌹🌹🌹

@@maryalison1321 I'm an atheist. Begone, bot!

@@rusinsr how are you doing

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 RU-vidRS IN THIS CHANNEL

wooouwed

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.

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 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 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..

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.

Huh, you also noticed

Ha! All my favorite creators are in here!

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? ;-)

Be aware mate, real Tom will never ask to cover the shipping fee. Be careful plenty of scammers out there

Hi integza

I wish he would post the files, it would take me ages to reverse engineer something nearly as good as that.

@@slartibartfast2649 ++

@@slartibartfast2649 He has. Look in the description. It's the first link "3D Printed wing STL"

@@grndkntrl that wasn't there before, I checked.

Yes sorry I forgot to post them at the beginning haha

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.

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

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.

@notfiveo Not needed with two lift rotors, even on a pure helicopter.

:P

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.

This.

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.

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!

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.

Not sure if the V22 does this, but I know the Harrier is/was able to rotate the nozzles slightly backwards beyond the vertical.

Be aware mate, real Tom will never ask to cover the shipping fee. Be careful plenty of scammers out there

They are certainly a strange thing to see go overhead. Presumably the sound is a similar interference effect to a chinook helicopter?
