The animations and explanations for aircraft stability were better than any actual private pilot curriculum I've ever seen. Well done.
I came here to say the same thing. I didn't grasp aircraft stability to this level until the day of my CFI checkride. Awesome explanation Daniel!
I'm also here to say the same thing! Excellent choice of words and pictures.
This explanation is better than most (concise and technical jargon free). A great intro to everyone that wants learn how a plane flies!
I agree you can now build your own plane
Was thinking the same thing lmao
Honestly, your explanation of basic aircraft fundamentals was better and more concise than a lot of the college classes I took for my AE degree. Would recommend your video to any entry level college students or anyone just interested in the basics of flight.
Yeah most professors are awful at teaching. They just passed the classes, got the degrees, and voila there to teach.
People gotta be good students and teach themselves.

@@iteerrex8166 everyone with a degree can teach, but not everyone is passionate about it...
@@heyitsmejm4792 Id say it takes other skills besides knowledge and passion to teach well.
I was checking out my dad's high school physics book from the early 40s and every one these principles were discussed .
None of this interesting stuff was addressed in my own physics classes in the 70s
This was extremely educational and interesting. You gave us the fundamentals we would need to design a plane
@@RepentandbelieveinJesusChrist5 gigachad
even though I have not studied flight physics, (as I am still young) the hours I spent on designing and testing paper airplanes proved itself to help me understand this video, your explanations were straight to the point and easy to understand. Thank you for this video and the amount of effort you put in. (18:52 Look closely at those horses, they are reacting and you can see a small blob presumably your aerodynamical space shuttle fall into there haha)
Lol same for the paper airplanes
Technically they are still paper airplanes, just pre-paper airplanes:)
I’m pining for a pun thread. Wood you mind if we use your comment, OP? Let’s branch out and see where this leaves us.
thats cz he pre-ordered
This channel is too well-documented for a PhD paper...
@@FilosophicalPharmer just leaf it be. We don't need to root around and force a joke
@@FilosophicalPharmer My dad hated puns. He would beat you to a pulp.
I could watch different iterations of these designs dropped forever, really cool to see how they all respond.
I agree, I'd watch this weekly if he released them
Until you get drunk Karen That's Trying to get Back to New Jersey Shore and she Said she Just Cannot wait And She is going to Take a Big Fat Dump Out of the Emergency Exit!! 😮 Because you know that Big Girl+Drunk+Drugs ÷Jersey Shores= OMFG.. Could you imagine those Farts after eating that cereal?
I'll try a magic spoon without that Drunk Teenager ! BTW ; WHY would you hire people like that?
The space shuttle design was epic. I was surprised how well it flew.
So thats where the random plane came from in my backyard
I haven’t even gotten to making the airplane yet - that explanation of the factors involved in flight was amazing!
You just made flight physics something understandable by everyone in a cool and concrete manner. Incredible video, I remember asking myself this same question. And you answered to it, you showed that anything no matter the wing loading can fly as long as you give it enough speed !
until you have to do the math associated with it. then it gets more fun.
I tried it out with an ashtray, it worked !
Could also use that ashtray as a 'remote control' for the TV (to turn it off), just give it enough speed.
@@Jila_Tana Aim right at the center of the screen.
Yeah you can pretty much make planes after watching this. Sweet.
If you strap a big enough engine to it, a BRICK can fly and break the sound barrier.
For practical non-littering, maybe a slight roll bias to keep them in the field is desired. :|
Maybe use steel over lead just in case you leave it
i always add brightly colored paracord sleeves. it doenst only look cool but also helps me find my shit
Do we now need a leftfield and rightfield wing option... (Left and Right wing don"t define the deviance adequately)
@@peterlustig8021 i fill them with TNT and iron nails so they self destruct exploding when they land somewhere and the nails flying away make whooshing sounds to better find the source of where it fell. it also helps if there are people around because you will hear screaming. nice little side bonus
@@snuffying i would add exposed lead and aim them at water sources

As an engineer It’s fun to watch you share your theories, iterate prototypes, and then test, test, test.
hey
glad to see your comment. have a nice time. i am searching job. but i also want to work on some projects.
wish you good.
And what kind of engineering do you do?
I'm sure the FAA loves it too. Dropping lawndarts from hundreds of feet in the air.
He lost many of the planes. Who knows how many houses or cars and other property were damaged.
Exactly what I was thinking too. I used to make cambered paper wings and rolled up paper for fuselages, and build my own gliders. Much like these but not 3D printed. This was 30 years ago. Gosh, I feel really old. Anyway I may have built some 200+ of these - all kinds of designs. I loved building them. They taught me everything about gliders and flying machines
PrusaSlicer 2.6 has the ability to add pegs and holes to aid in aligning and glueing models that are printed in multiple pieces. This might help you with aligning the two halves of your models.
It is ultra convenient that this is automated, I and any other adequate designer have been doing this in large prints or assemblies for years (I tend to use small steel pins (we have basically unlimited supplies of -surplus- machined 1.5mm "dowels ) inserted into matching holes, they are incredible strong providing early alignment support at the bonding layer (better than printed dowels for fine detail)
exactly, the whole time i was wondering: why doesn't he just add some pegs on the inside to help with the alignment process
That was one of the best explained videos i have ever watched on any subject. I haven't studied fluid dynamics, I don't know much about aircraft engineering and i certainly am not involved in the flying community. This video taught me ALOT. And I was enthralled the whole time. I think it mostly just comes down to how well the video was made. I give you my thanks.
I wanted to say that the way you explained the way the wings are tilted etc and how it helps it lift off and stay stable was so much better than anything I’ve heard, absolutely amazing!! Thank you for expanding my knowledge 😅
Solid wood slope sailplanes built for high wind are a thing. They fly fantastic!
i'll search for some
Yeah! Like the Thorn!
I have a all wood 1.5m slope glider I bought years ago called The Thorn......made out of poplar I think ? ..flew fine...still have it..
@@steve_beatty yeah! it was even made the same way these wooden planes in the video were made. My boss has one in his office.
They're out of production now, unfortunately! Super cool though. I'd love to get my hands on one. If you have a spare, lmk!
I haven’t gone past 4:42 but I just want to applaud how understandable the explanation for passive aircraft stability is. I fly model airplanes myself, I ‘know’ the things like dihedral, but I can never really understand why they work until I found this video. The visuals and the ‘pretend like we’re the oncoming wind’ really helped better understand the concept.
1940s Japanese engineers at 16:50 be like: congratulations, you made a successful plane.
Thank you very much for the succinct and comprehensive explanation of passive glide aerodynamics! I have been making planes from foam insulation for a few months, using weights and adjusting the rear stabilizer to get a flat glide path. I will be using what I just learned to refine my builds and get better results.
27:20 That's not flying, that's just falling with style.
Dude I could watch hours and hours of these. This would make killer "fan showdown" type of content.. Where people send in crazy/well thought out designs that are printed off and drop tested. Super cool content to watch!!
yeah, i wanna see some smoke n wind tunnel tests...
about the only bit of aforementioned channel i can stand watching ;)
I greatly appreciate the tremendous effort and work you put into this project. It was both educational and fun to watch, but took a lot of dedication on your part. Good job! Rudolph
Just nice to see and hear blokes having real constructive fun.
i love how you make your videos. they're informative and genuinely entertaining with how you actually craft projects to show real-world effects on the things you talk about.
I was curious if Revell Models were able to fly, so I bought a few and tested them with a large rubber just like you did. They flew suprisingly well and very far, and I never expected how stable they flew considering how small they were. Maybe you could try that in a video too, it was a lot of fun.
I had the most success with a 727, Buccanner and suprisingly a Su35
I would like to see that in a video!
It's interesting that those were all jets, which are designed with the heavy engines in the middle, so the model probably has a fairly accurate CG. Prop planes are mostly designed for a heavy engine in the nose, and (as most kids discover) don't balance when you try to hang them from the ceiling by looping thread over the wings.
Actually the CG was still very far in the back. I had to add quite a bit of weight. If you built them as a Kid and left the weight out they would always tip backwards with the gear out.
Jets are still better since they have a longer nose and larger rudders and elevators compared to props. And I feel like the sweeped wings add flight stability aswell.
Sth like a 190A or Biplane would likely be not possible to fly at that size due to all this, especially as a glider.
did they survive?
Yes, still have them, tho the noses are very scratched. They can take a suprising Amount of damage.
Wow! This video is almost 28 minutes long yet felt like it was around half of that, the immersion was very satisfying. Well done rctestflight.
i'd quite like to see the shuttle design milled
few small light shuttles from one piece.
omg. they wood be more than brothers
Or just made into an RC airplane. I might actually do this.
hes made alot of videos on shuttle like craft w delta wings and lifting bodies and such
Got to admit that this type of content at this level is hard to find, good job man I'm proud of you.
I'm pining for a pun thread. Wood you mind if we used your comment, OP? Let's try branching out and seeing where it leaves us.
@GunsAndAmmo3 just make sure it's nothing plane
@@GunsAndAmmo3I saw some great puns in the logs of this video
Thank zou soooo much for the fyziks at the begging of video ❤🙂🙂
The explanations at the start of the video caught my attention. I make airplanes regularly but seeing the explanation behind it caught my curiosity. Made one using the directions and it flies perfectly. I did a bit more research on the topic and it may be my career choice in the end. Thanks mate!
The animations and explanations regarding aircraft stability surpassed any private pilot curriculum I've come across. Great job!
the explanations of passive stability on all axis are amazing
My dad was a commercial 747 pilot for about 30 years, I feel like I’m back in childhood having people explain YAW to me again😂
Thats sick
Dude I wish I was ur dad 747 is my favorite plane
"Can a Solid Wood Airplane Actually Fly?"
Yes; but it might more accurately be called "falling with style".
Again I say, an outstanding video. I have nothing but respect for people who do the actual R&D to test out their curiosity. BTW, I'm pretty sure stall spins are impossible for an uncontrolled plane to recover from. No matter how balanced, straight & level it flies, once one wing stalls, it's over. Really great video. Also, one thing I've known from Day One: With enough power, a brick will fly. At least you littered the countryside with enough toys that the children of the squirrels & raccoons will have something to play with!!!
Given enough thrust, anything can fly! :D
yep, at some point even wings are unnecessary!
@@outandabout259 - below critical airspeeds wings are pointless. Lol..
you need to use alignment holes and pegs to ensure that the two halves are properly aligned. I actually use spring loaded pins that I 3D print to hold the two halves together, if you use enough of them you don't need glue. The pins are originally from a fairly well-known 3D print, the gear cube
Good effort. It was really educational. Thank you very much.
The aircraft yaws about the center of pressure, not the center of gravity. Wing sweep also contributes to yaw stability.
I think a video where everyone can submit a custom design in on shape and you pick the most interesting ones and print them would be fun
I was thinking that the whole time. Like the 3d printed fan showdowns!
@@mikebergman1817 A 21st century version of the high school paper airplane contest. As cool as it gets.
That reminds me my own experience with 3D printed shuttle glider. Stalls, lawn darts and flyaway.
To deal with the slight glue shift, I would recommend adding pins to make sure you get the alignment and it should not shift while gluing.
When you mentioned seed pods would you ever entertain the idea of making a video going over the arrow dynamics of different common seed pods? I think it would be really interesting to learn about seed dispersals and maybe how far different trees can travel on their own.
Have to say; been secretly creeping around your channel This last year without contributing to your comment sections. Have to say ‘thanks’ for all the entertainment plus education value you’ve produced for the world. I’m pretty lame in book smart section of life. Been real fun to watch someone so passionate for their craft. Great job on *everything* you’ve accomplished so far. 👍
Should have used Kerbal Space Program 2 to do the demonstration at the beginning. You can live move the wings and it will show you the center of lift and center of gravity.
Very cool to see your drive to experiment and refine. Thanks for sharing!
You clearly put in a lot of effort with many many trials.
The explanations were also spot on I learned a lot.
You should print in PHA plastic, it's supposed to be biodegradable in nature (unlike PLA which is "biodegradable" at high temperatures in basically an industrial setting.
Collorfab has a filament called AllPHA, which I've tried and it works very well, kind of prone to warping though.
I’d wager that PLA miniature airplanes make for pretty good rocks, definitely better than say, a garbage bag.
@@jumpvelocity3953 sure, they don’t run the risk of entangling animals or anything like that, but they will still be worn down into micro plastics and end up in the bodies of animals.
7:12 I was looking for those strange patterns in the acrylic and couldn't "see" them because I honestly thought they were a deliberately applied wall treatment seen through the acrylic until I realised what I was looking at. Those are so cool!
Your explanation of physics is really good with other aviation related videos i could learn a bit of physics in a week and in 1 video you doubled my knowledge
This is fantastic. The final balsa design was gorgeous and I loved the drops where it lawn-darted so perfectly. Have you considered adding AirTags or similar to help recover test articles? I also wonder if there's a low-footprint avionics sensor package that could gather accelerometer and pressure data at least to help profile the flight.
To avoid issues with misalignment in the glue up, you could put two or three holes for pins in both halves, and then print dowels that will fit snugly in the hole on both sides, to lock the halves in place in a similar way to the pins you used to hold the block of wood in place.
on 20:25 it was gliding so smoothly he thought it was a bird 😂😂😂
the drop from the copter is awesome
I found when designing deltas years ago it helps if you can hold it at stall angle ( 30 degrees or so ) and still see some fin, it stops some of the bad handling.
I built a very high speed delta for a friend and it would never land once the engine cut, just flick stall in, you had to aim at the ground and never pull up.
On a rebuild I made the fin much bigger and it became a pussycat.
Man... I put this on for 30 mins of background noise, and now I'm 30 mins behind on my work! You explained some concepts I've never heard about, and I've been a casual flight theory observer for my whole life, well done! Makes me want to get a 3d printer
i'd love to see a much larger RC version of that shuttle design. it looked awesome!
Came here to say this. A larger, powered RC version of the shuttle looks like it would be a delight to pilot.
Excellent descriptions and explanations throughout.
the explaination of the aircraft and stuff at the start was really easy to understand good job.
this is my first time on your channel. I really enjoyed all the info and the 3d printing used in the making of these planes. What a great video!!!! thanks
That was cool! Also, I think a wooden plane resembling a DC3 is way cooler than a shuttle-shaped one :D
I have been a professional pilot for many years, and you have just reminded me how fascinating aerodynamics actually are. The small things we take for granted on a day-to-day basis!
All the vocabulary is very confusing but proves its importance very obviously. Thanks for sharing this and hopefully you enjoyed your time making and experimenting with the planes as much as I enjoyed watching and learning about flight vocabulary
Iv never seen dihedral explained so well before..
Great video!
I'm a licensed pilot and even I learned more than I knew before about aerodynamics and stability. Great job. Also, a lot of great toys to play with.
27:05 The wood plane wanted to go back to being what it used to be 😂
My brain: AIRSPEED LOW AIRSPEED LOW
22:32 OOOOAAAAAUUUUOOOOH Had me dying 🤣
Nice video though!
It's so interesting to me how small creators have found ways to explain and test basic principles of almost everything these days, and this made me understand more about flight than I had previously known. Well done.
Im the first person to like and reply to this comment
I'm normally a very big visual learner and your animations and explanations were so easy to understand! I actually understood everything you showed and said, I love it, please keep adding small sections like this in future vids!
The wood plane at 25:48 reminds me of an AirTransat plane I once flew on.
My great grandpa had a wooden airplane (not remote controlled of course) and I remember that you had to fill the front of it with metal balls and then you would throw it of a hill for example, and it actually flew really well despite me being pretty sure that it was made out of solid wood.
The CRAZY amount of work that goes into these videos is insane. Great vids! Keep it up! 😊
At 12:06, I believe that was just a simple accelerated stall. The way the aircraft tumbled likewise to its prior AOA makes it appear like just a stall.
One of the things I noticed was the reaction of Adverse Yaw, in this case it appeared to be the affect of one of the wings at an abnormal AOA compared to the other wing, causing the other wing to have more airspeed, and the right wing holding the fuselage back, thus yanking the aircraft to the right. That, of course, seemed to be the result of an Accelerated stall.
Your delta wing recalled a toy plane I was given as a kid. It was an all plastic (!) delta with a 3D fuselage and canopy! It looked real, unlike the common balsa cut-out gliders which didn't. I'd always wondered if it was possible for a plastic plane to fly, and now I had one! I took it to my new school (only 100' or so from home that year) and the class crowded around to watch me fly it at recess. All it needed was a stick with a rubber band on it!
I pulled back and let her fly. All the way across the rough field it flew at about eight feet, before dropping gently before the road. Into a small pile of rocks. Which punched in the nose. As in pieces. So much for flying plastic airplanes at age 7. And so much for "unbreakable" plastic.
Love this video it reminded me of whenever I was a kid and got into aerodynamics with paper airplanes and discovered one specific design that I got an over 20 second flight time from the ground.
So interesting!
But i was constantly afraid that someone was gonna get hit by a plane.
I think its quite dangerous since the planes randomly fly somewhere.
Yeah I hope no one got hit by a flying wooden plane.
@@AHN1444 can tell if that comment came from genuine concern or if you're referencing the Chilean air disaster back in '83 😮
@@skussy69 which chilean air disaster? It was genuine consern
If such a plane hits someone, it would cause severe injuries, because it's so heavy, solid and fast. It even may kill people. Just look how deep it's going into the ground. You don't want this going into your stomach.

It would be awesome to put a little board computer or microcontroller with some accelerometers in the hollow body of those 3D printed gliders and see what the actual flight profiles looked like. But then I guess having them explode on impact with the ground or getting lost would be much more expensive.
A simple accelerometer and microcontroller are really cheap these days and they can be operated using really tiny batteries. It should be significantly below 10 bucks as long as you don't include Telemetry, GPS, a proper flight controller, etc.. but you probably need to do some simple coding, soldering etc..
@@florianvahl5494 With a decent 6 total DOF accelerometer/gyro platform you can do a pretty good job of having it fly a path to a destination, and maintaining controlled flight, as long as the accuracy of the two are good and the gyros don't drift too much over the flight duration, meaning not much at all. I guess you would need a compass and an airspeed sensor to really have all the data to make it simple to do with a controller.
Pretty much all the necessary components would be mostly solid state I believe so even if your plane met a tragic end as long as you can recover it most of your electronic components should be reusable I would think
That is the origin of this channel basically - any ardupilot-compatible flight control board simply does this in their log file or telemetry link (when they appeared on the market multiaxis (even hyper dimensional) telemetry became affordable for any application).
I like that you actually show the clips of you failing, it makes a really interesting video, and it proves that you cant ever get something right the first time!
Cool how the most stable examples all resemble classic examples like the C130, Avro Vulcan and the Space Shuttle.
26:42 that's what she said
Your content is a goldmine because you clearly enjoy experimenting with your models and you explain very easily how aerodynamics work in real life, keep it up !!
The slingshots... I would try aiming upwards... maybe start at a 45 degree angle.
I used to make these book of paper airplanes called "White Wings" which were designed by a Japanese engineer. Made of oaktag that you cut out of the book and glued together layer by layer. It was the greatest book of my childhood.
It used a rubberband slingshot to a tiny hook made of a staple, and you needed to aim upwards (30-60 degrees) rather than horizontally.
The lifting-body gliders remind me of a design for an air-droppable refugee aid pack that someone designed. It was a totally passive glider made of cheap and biodegradable materials, with ballast and frame-fillings made out of foodstuffs. The idea was to make something akin to those styrofoam gliders, but made from puffed rice, with a few solar-powered knick-knacks.
There was a 1.5m slope glider called Thorn than was milled from solid poplar. They produced and sold them.
Could try using AirTags to affect your CG, and then it'll help with finding the plane when it flies off.
Or something like a simple tone generator with small battery.
Im on youtube for hours every week sometimes every day... Love RC and cool stuff, can not belive this is my first time finding this cannel.
It is awesome, thank you and keep up the good work! 🙏🌞
In the playing around I've done with r/c flying wings and deltas ive found that once wing loading gets high enough you need to install wing fences. The swept leading edge encourages spanwise flow, without fences to stop it a stall at the wing root will travel out to the tip and suddenly you're in a spin. Airfoil selection doesn't help much, although a thicker section will help. Tip washout doesn't seem to help at all once wing loading is high enough.
Changing to tip dihedral rather than gullwing dihedral is going to increase the effectiveness of the dihedral in stabilising the plane, and eyeballing it i would say that increasing it a bit wouldn't hurt either.
Just my 10c worth...
I really think you're in my top 3 creators to watch. I really look forward to watching your great ideas come to life.👍👍
Thanks for showing us how you landed the drone. I would have spent too much time wondering if you had a spare channel to jettison the guide pole. Actually, until I saw you land it, that's what I was thinking.
I once found a fresh fir branch that flew pretty good. I threw it horizontally and it gained altitude. Perfect weight distribution and weight, ok wing area, but quite a bit of drag.
Hi,
Amazing work and I must say you have a lot of patience. I'd never be able to do so many prints and so many iterations. hats off !
However, I'd like to see a larger size of your shuttle design in an RC configuration with a pusher prop. See how well it performs, coz I think you've designed something amazing there.
Good Work !
"That's not flying, that's just falling with style!"
Hey, idea for this series: what about a golfball dimpled airplane? Since you have the CNC, put a ball nose end mill on it and mill the dimples to see if you can reduce drag by creating mini vortices along the fuselage.
This comment reminds me: wasn't it the front/back split double delta that flew so well? Could the presence of the very slight layer lines on the surface in different directions do weirds things to the airflow?
The main reason dihedral applies roll stability because the lift vector on the level wing is vertical to gravity while the tipped up wing has a lift vector that is slightly out of vertical to gravity, thus the tipped up wing will produce less lift in the vertical axis than the level wing, so the aircraft will naturally hunt for equilibrium where both wings have the same amount of lift which would mean the aircraft is level in roll axis. Its easier to visualize it when you draw arrows perpendicular to each wing making them both the same length, and then draw a line from the fuselage representing gravity. Look at which arrow reaches farther down that line preopercular to the gravity line. The longer line is creating more lift in relation to gravity than the shorter line, so the wing with the longer line will lift up more than the wing with the shorter line until the two lines are equal perpendicular to gravity.
This video was way more interesting than I was expecting. Those gliders were FAST
I think the real success here was the 3D printed shuttle. That was incredible!
I think the real succes was not having a chunk of wood go through anyones window :D
@@johndoe920lmao, or kill someone!😂
I had metal airplanes as a kid that I used to fly in the local swimming pool. It would go from the shallow and all the way to the deep end
It's always funny when Dan's creations manage to escape.
Watched from Old Harbour Jamaica and I've learned a lot.
