That man talking about the helicopters his eyes were like I am going to stare into you soul
thats was my first thought
EngSpringSpan Ikr
EngSpringSpan he looks super scared
I must be looking at a different video. I dont see scared or staring into my soul.
😂😂😂
The series is working. I'm hoping you learn several things each video, and ask awesome questions like you just did. That topic is going to be a whole video, and the answer will blow your mind. I know it blew mine!
The way he controlled that helicopter made it look like a dragonfly's movements.
I've been a big aviation buff for a long time so I mean this as a big compliment when I say your quick, simple visual explanation for how all of the controls work was an easier explanation than I've ever seen or read. Bravo!
Collective pitch = W(up) and S(down)
Cyclic pitch = Arrow keys (direction of tilting)
Anti Torque = Q(left) and E(right)
Yep, learned it all in GTA San Andreas
faking genius dude (y)
I didn't understand :(
Directions not clear, kite stuck in neighbor's tree
Bayezidh Tanu his keyboard
This is a much simpler and easier way to understand it, thanks!
This is possibly the best channel on TH-cam, it doesn't even feel like learning something because it's fun to watch, it's just a bonus that you learn something as you are watching the fun video if that makes sense. Keep up the great work!!!!
what the flip!!! that piloting at the end was crazy!
Watching that little RC helicopter fly, all I could think about were dragonflies. Very erratic, very agile, and yet very precise.
lol, great minds think alike :)).
I wonder if that could be possible with a real size heli, but even if it is i think the pilot would take a hit if on board.
To be able to make those maneuvers without losing control, I think the whole craft would undergo g-forces too strong for the pilot to withstand, let alone the craft itself.
Denver Eduard yes and no, aerodynamics work differently at bigger scales. And also, the pilot G force issue as u mentioned
Wow, I had no idea a helicopter blade was so complicated or adjustable, or that it never changes speed in flight. Keep blowing my mind Destin! Thanks!
80 hours of ground school and this blew my mind. Toy helicopters need to be implemented in the commercial course. Top gun high fives for your youtube wizardry
The guy from the Smithsonian looks absolutely terrified.

You're going to explain how choppers work, and you're gonna ENJOY IT!
+ZeD More like "Explain Helicopters or your wife dies."
Oh my gosh he should be a meme!

@Maaartah (note that I have not watched the video) When the rotor spins the air doesn't just go straight, if also goes outward and in a circle around the helicopter. The air spinning around the helicopter creates the opposite effect of the helicopter spinning. That's why the back prop is always spinning(to compensate for this effect) when the main rotor changes speed the back rotor needs to change speed as well. Hope that answers your question.
Many larger liquid rocket engines have something called "Thrust Vector Control" or TVC. The entire nozzle can articulate, thus producing a thrust vector that is off axis from the rocket itself. The mechanism is similar to those little linkages in a gorilla pod, except usually there are two linear actuators which control the direction of the nozzle gimbaling. By the way, an ideal rocket nozzle will expand the gasses to atmospheric pressure by the time it exits the nozzle bell.
Lead-lag hinges are on semi-rigid rotor systems. The terms you're learning about refer to "hunting". You're getting into very complicated aerodynamics, which is AWESOME.
I fly RC helicopters and I make videos on how to fix cars. I LOVE THIS SERIES!
Noice
Do you like rc helicopter with a fly bar or without a fly bar
@@minepaperstudio5683 flybarless is cooler
You guys rock! My life honestly revolves around helicopters. It's such a treat to know you'll be working on this series over the next few weeks! I hope to be a pilot one day, and while I already know most of the content you've uploaded, it's great to get a refresher and see people getting excited about rotorcraft!
Keep it up! And make those videos as longer!!!
3 years after this series was uploaded and I'm getting smarter everyday trying to learn how to build better helis in Besiege, lol. The physics are amazing but Besiege doesn't allow such fine designs so you've got to fudge it a bit. =P
+The SilentCaay Channel Well technically maybe if you went into a bigger scale it MIGHT be possible, just not not very good because the rotor blades can't scale alongside it, only the rotor itself, basically adding weight on top of the very little lift you already had. Unless you use a steering block to turn the propellers, that could be useful for controlling lift,
The SilentCaapy Channel c ce
Same here. Im also doing it in a game called Plane Crazy. its on roblox but isnt autism
Love this series! It would have been cool if you guys attached a camera to the end of one of the blades as you were rotating them slowly to display collective and cyclic pitch. The camera would tilt at an angle relative to the horizon, depicting the angle imparted on the blades by the swashplate adjustments. This would have been especially useful for displaying the cyclic pitch because the camera would tilt at a different angle relative to the horizon depending on the blades position around the central rotor.
That cleared up a lot of questions I had but never came across the time to go research myself. Can't wait for the rest of the videos!
I am SO glad I decided to subscribe. This looks like on of the most badass educational series yet! Cool, awesome, informative, and actually teaches me something I didn't already know or understand.
wow. helicopters are truly amazing machines. i had somewhat of an idea how it all worked but this video showed just how complex these things are. it's pretty cool. thanks for the video.
That guy at 1:01 drank WAY too much coffee that day. LoL
how could anyone possibly "dislike" this vid!?!
Great work, and thanks for the awesome, educational videos!
all this years this is the channel i was looking for... answers to so many questions
Now my interests in everything RC and everyday science converge on Destin's channel. Awesome coverage of helis, Destin. KUTGW and Thumbs up!
This is how it's supposed to be taught, totally simple and neat. keep up the good work, thanks a lot Destin
Wow I've never seen such agility from a machine, that's incredible.
Congratulations! The next few videos should be very interesting to you. I recommend paying close attention during the "why you don't need a parachute" video.
Thank you so much I learnt allot I'm going to nag for pitch helicopter for Christmas, and say how much it can improve my understanding of helicopter physics by actually trying it. Awesome vid.
I'm a Mechanical engineering student in Sweden, these videos are just awesome!
i tell you what, i work on airplanes for a living, and this blew me away. smarter every day!! love it man, keep it up!!!
Pitch is the change in angle of attack of the bade. As it goes around it takes more, or less of "a bite" of the air.
I already knew this from my RC Helicopters but I still felt like I learned something. Especially how the swash plate works that's so awesome.
If the helicopter is designed for this type of flight, it would certainly be possible. Watch the next video and we'll discuss upside down flight with the use of high speed video for analysis.
Omg thanks for the tail rotor 'stop spinning' thing I can now fix my heli that I made. Thank you!
Good suggestion. We thought hard about that, but the forces involved could damage this very expensive helicopter.
Hi Destin. Really enjoying your videos. This is a great explanation of how helicopter controls work, but it only scratches the surface. I can see you like to get into the nitty gritty fine points so explore gyroscopic procession and dsymetry of lift and see how helicopters are engineered around these two truths of physics. It's really incredible with lots of clever people working these things out.
"Dissymmetry" yeah, i messed that up.
I apologize for the hig gyration during the flip at the beginning. Not sure what I was thinking there....
4:06 OH GOD WHAT IS THAT.
3D flying. it's a style. I do it too.
*magic*
KpilotRCHelis Looks like the chopper was on drugs
SAME REACTION xD
Kothan Guzman Hahahahaa
its either shock or information overload but all i can physically say is "i want one"
ever since i started watching (and subscribing after the first vid) i have found soo much knowledge
you are a champ
It's awesome and entertaining! Love the series!
Destin absolutely loves what he does.
How these helicopters work makes perfect sense to me, now. But I'm STILL blown away by the fact that cyclic pitch changes the angles of both blades in unison every rotation... that's so fast...
This is amazing! I never knew an rc heli could do such things. I learned much. I'm a happy new subscriber. Keep it up!
I can't wait to see the rest! I've always wondered how a helicopter could fly/ hover! I'm so glad I subscribed!
These videos are awesome. Thanks for doing what you do !
awesome video. I was really hoping he would have shown that kids hands on the controller. I wanted to see him doing those crazy moves on the joysticks.
Dude when are you gonna upload the next video? i've been checking every day. I can't wait!
I posed the question hoping you would think about it. The answer you seek will be revealed in due time.
Yes, it really worth watching this video. Thanks.
04:06 was somehow so hilarious for me XD
The helicopter is possessed. That scene doesn't appear to physics. lol looks fake
How many changes a second happens on that mechanical part under the main blades??? This is soooo interesting!
Thanks for this Destin. Always wondered, never got around to researching it.
I've seen over a hundred of ur vids, but 2day my friend, u got ur self a new subscriber! :D
Paused it at 0:13 at went and bought one! Can't wait to fly it!
Alpine Ace and do some crashing tricks
How fast you can fly and change direction without losing control, amazing!
hahahaha "how you doing mr. ledbetter?" "i'm richard ledbetter" hahaha...dude..he said hi..
+alex hernandez I swear I thought he said he was ETHAN BRADBERRY!!!
Once you have seen how it works it is pretty simple but oh boy inventing this system from scratch? Work of a genius :O
hey Destin, I think you did not explain how helis don't drift, right?
btw, Helicopter physics is the best series you made. Nice stuff!
Thank you for making awesome videos my good sir.
i love the music on all your videos
I got it from my local library (libraries are like the internet only you can smell the books) Dewey Decimal system: 608.7 COO "The Inventions of Leonardo Da Vinci" Magaret Cooper
Imagine coming up with these mechanisms from scratch. Insane. D: Helicopters are excellent :3 Looking forward to the next video ^^
Very cool. Thanks for the education and entertainment!
dude that piloting at the end was unreal!
You just explained something that i have spend manny an hour pondering and for this i thank you
Nice editing at 1:42, so smooth i barely noticed. Maybe i'm just gettin old :P By the way this series is gonna be awesome!
@Dialga355 Animations are on the way. Sarah Xu (who drew the intro helicopter) is on board to start some hand-drawn animations once her course load at Vancouver Film School lightens up in a few months. Improving production is expensive, and a large reason this series has remained so good has been by limiting advertising which might negatively affect the program. All in due time.
One word... FUN!
Thank you!
Learned so much, Thank you!
I was a little confused by this too, but I thought about it and rewatched the video and it makes sense now. I had to make the rotor shape with my hands to realize that if you tilt both in the same direction while maintaining their positions relative to each other, one side will produce more lift and the other will produce less. However, the rotor tilts the opposite way each half rotation to keep lifting on the same side. Seems a little overcomplicated, but mind blowing nonetheless...
ive seen that guy do crazy stuff with his helicopter, and it still doesn't fully make sense how thats possible, thats amazing
Interesting stuff good camera views of the heli preforming!
Waited the whole video for this, was not disappointed xD
Cool, I learned more from this video than any of your others! Thank you!
My God will come through always, always. Lovin the shirt!
I've been working on a design for a helicopter I want to build, but my budget for research is whatever I can find on the internet. I will pay close attention to this series. Any statistical information you can find would be awesome.
I mean i knew that heli's were very hard to fly but WOW. Thanks for these amazing vids.
that is the badassest thing ive seen in my life!
Intro was awesome!!
There are 3 ways we make helicopters stop "drifting" also called translating tendency. 1) pilot input 2) cyclic rigging 3) An offset rotor mast. The question was never really answered in the video.
Summing up:
Collective lever: thust magnitude change
Cyclic lever: Thrust direction / pitch change
Man, that is so interesting. I just realized that the shuttle's engines ARE displaced sorta "above" the soldid rockets and liquid tank thus off of the axis of rotation. So you could get a moment by vectoring the exhaust sideways. That sorta explains why you can see the shuttle main eninges swinging when the engines start. Derp. (Facepalm) lol. Thanks Destin. I just got smarter today!
You know I always thought about how helicopters worked. In my mind I tried to imagine basically what the swashplate is. I just didn't think it was conventional/efficient. Great series!! Now do a barrelroll!!
That was a good start. Cheers.
destin i love you I've all ways wanted to be a helicopter pilot and you've helped me set that plan n motion thank you so much.
So amazing.. really nice series
No. A water surface will act like a solid surface and provide the 'air cushion' for an In-Ground-Effect (IGE) hover. The helicopter's rotor system is 'pulling' air from above and forcing it through the system to create its lift. A helicopter actually requires less power to hover IGE. If the helicopter has enough power it can hover Out-Of-Ground effect (OGE) as well Sometimes, an overloaded helicopter may not have power to hover at all on any surface and this may be what you are referring to
I learned something new today! Thanks Destin!
StarWolf watched this.
Destin, your friend's helicopter skills are making the dragonflies jealous!
4:40 Because flying straight is too mainstream!
Anyway I did not know how the blade worked, I honestly thought that the speed of the blade determined the altitude of the heli. Can't wait for the next video!
All this way loving helicopters without understanding their movement mechanics, thank you!
this is sooo cool! thanks for posting. wow, have learned something today...
another video from Destin another dozen things i've learnt! keep them up Dustin! :D
i had to watch this video to understand the 90 degree out of phase concept, because only here i saw that the rods for the pitch control are no aligned or directly under the blades. now all makes sense :D
This is super convenient for me because I'm currently learning how to fly a real helicopter! I just learned about all this stuff last week and in less than a month's time I'll be flying a real Robinson R44 helicopter!
Think I'm gonna get myself one of these...that was awesome.
I aim to please. Thanks for trusting me with your subscription.
you look like my computer science professor - with the difference that he looks very depressed.. its funny to see "him" here on this video energized and happy.. ;) - BTW, the helicopter control skills are awesome!
Great Video.. I'm Really enjoying it.
Thank you!!! I always wondered how the blades worked. Off to watch the other videos! :-D
