Legends still waiting it to fly..

I was waiting for those propellers to collide😝😂

Next level flexing. I had to watch it a couple times to see that the rotors are mechanically Linked. That’s some incredible engineering bro.

Wonderful. This requires precision tuning of rotary blades so that they don’t collide in flight.

the propellers work in perfect sync.

How do you manage the two propellers and their respective blades without colliding each other while rotating?

This is the most realistic startup of an RC helicopter that I have seen

Chinooks are very cool. To those commenting about the rotors “being in perfect synch so they don’t collide”, the rotors are on different planes, they can’t ‘collide’.

My disappointment level is immeasurable & my whole day is ruined 💀

Sounds like a jet engine but it's battery powered. Good job on your editing.

Very nice 👌👌👌... it looks a build in progress and frankly it is extremely encouraging.... tandem rotor Chinooks are extremely complicated to replicate in RC scale .... Much appreciated .... Great effort !!! Congratulations

Sound : 200 % Will fly : nope😊

😒I thought I was going to fly

Tem um intervalo das asas giratórias...e uma gira horário e a outra gira anti horário ...massa coisa de gênio!!!🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🐎🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🌲🌲🌲🌲🌲🌲🌲🖤🤍🖤🤍🖤🤍🖤🤍🖤🙏🏽🙏🙏🏽🙏💯💯💯💯💯🙏🏽🙏🙏🏽🙏🙏🏽🙏🙏🏽🙏🙏🏽🙏🙏🏽🙏🙏🏽🙏🙏🏽🙏🙏🏽💯💯💯💯💯💯💯✌️✌️✌️✌️✌️✌️👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌

Legends say its blades were still rotating....

Amazing how as the propellers pick up speed looks like they slow down.

how the rotors' rotational speed catches up with the camera's shutter speed is quite satisfying to watch

Вертолеты продольной схемы, такие как американские СН-47 "Chinook", CH-46 "Sea Knight" советский Як-24 конструктивно можно назвать "близкой родней" синхроптерам фирмы Каман, потому что плоскости врачения винтов на некоторых редимах полета пересекаются и если бы не была обеспечена синхронизация скоростей вращения винтов, то винты бы "схлестнулись и разрушились.

Please make it lil bit longer to reduce our tenstion😵‍💫

Love the sound just amazing 🤩

Had a beautiful one when I was 16 flew perfect sold it bought a 63 impala with hydraulics

Thật đỉnh. Tính toán vòng tua ,hệ số vòng quay có thể lệch bởi do dòng vào và ngược chấn dòng tạo ra của chính nó ... mong chờ video nó bay lên ❤❤

Move to fly❌ The important thing is movement✅

My mind tells me to put my hand between them 😂

The motor synchronisation is perfect love it 💯🔥🔥

Luv the engine spooling up sound at the start. Very realistic

Wow, good work. You got the clearance correct without the blades hitting each other. It's still possible for them to hit when flying tho, so you'll have to do a flight test next.

Propeller 1 : watch me dude.. Propeller 2 : right beside you bro.. keep running 😂

For those of you who don’t know, helicopters actually have what one might call a transmission - the rotors are synchronized because they are driven by the same engine and synched via what you could essentially call a gearbox or transmission or simply by connections setup in such a way that the blades never go out of alignment/physically can’t unless the shafts snap or gearbox brakes (all depends on the setup) - imagine two spinning wheels on a car without a differential, if you spin one wheel with your hand, the other wheel will also spin on the other side at the same speed… also, helicopters typically don’t change the speed of their rotors while flying (unlike drones), instead, they change the angle of each individual blade. With dual engine helicopters it’s the same sort of concept - two engines put power into one gearbox that spins everything in a synchronized manner. There are a bunch of different ways this can be done but obviously there are ways that are more popular than others due to efficiency, safety, cost, and all the other factors one might imagine affect this system. Even jet engines in huge airliners have gearboxes as interesting/crazy as that sounds - for regular “every-day” helicopters, the top and back rotors (the small rotor in the back) are also synched and this is done with the gearbox so one engine can drive two rotors like a four wheel drive car type of concept and the helicopter is steered by the pilot by a linkage system that changes the angle of each blade on both the top and back rotor - so you can add more thrust from the back rotor to spin the helicopter around its axis which effectively turns it, and/or you can add more or less thrust from the top blades to go up and down… on helicopters such as shown in this video that don’t have a rear sideways rotor it is turned by changing one blade’s angle a certain way while doing the opposite on the second rotor thus creating a sort of imbalance to one or the other side. It’s weird and cool, I recommend watching a video about it. But the speed of the rotors typically stays the same throughout the entire flight (unlike a jet plane that speeds up and slows down its engine to gain thrust) and the sound changes because of the vibration of the air due to the changing angle of the blades. So when a helicopter is chilling on a pad with the rotors spinning, they aren’t moving faster than they would be when it’s flying - however, obviously, if you change the angle the power output of the engine has to also change to accommodate the varying difficulty it takes to spin the blades (depending on the circumstances and load). So if you’re towing an adult elephant around Africa in a helicopter, your engine will certainly need some extra fuel to keep those blades going compared to sitting idle on a pad.

Mind: Place your fingers there Me: what? Why? Mind: Just DO IT!!!

Я понял теперь почему от такой конструкции отказались вертолёта. Там где лопасти совпадают друг с другом,в этом месте создаётся повышенное давление воздуха и приходит это давление на сам корпус вертолёта ,что начинает его толкать обратно в низ ,тем самым снижается коэффициент полезного действия в этой области. Затрачивая больше топлива.

Я думал они же могут столкнуться, но понял они движуться полностью синхроно на 💯💯💯💯💯💯💯💯💯💯💯

I’m probably not the only one to say this, but that’s frickin cool

Why i am getting some final destination vibe from this😰😬 although i know that cameramans are immortals😅😂

Sound is coming before the propellers started rotating 😂😂😂.

Legends waiting for both propeller to collapse by hitting each other😂😂😂

Parabéns. Fico feliz pela sua engenhosidade. Gostei muito. Muito inteligente.

The whole time i was hearing "Hora,Hora,Hora,hora,Hora,hora,hora......" Getting progressively faster🤣🤣🤣

The take off will be the most best part but why did you end it😅😅

Good keep it up and work hard with your silence and let your success be your noise

Wow Really appreciate RC TOY What a Great and Stunning sound ☺️ Love It

Me to upar udne ka wait kar Raha tha.🤣😭🛩️..Omfo..😁😜😍

I didn’t know electric motors didn’t have instant torque and had to spool up like a turbine engine lol

Achei que ia decolar kkkk mas gostei da sincronia das hélices pra não tomar uma na outra 👍

Art of engineering 😂 propeller never collide 😂😂

With my luck, the propellers would smack each other off on the first try 😂😂

It's been 2 years and I'm still waiting for this plane to fly

It is interesting that the rotation does not interfere😮

Me :when that leaf will meet each other 😂

Everybody seems here Helicopter doesn't fly and and laughing on him but anybody doesn't seems his hard work that he made. A big round of applause to you , Brother 💐💐❤️❤️

Very good my friend sending full support from Indonesia 🇮🇩

That is really cool!!! How many channels are required to operate that, just the two rotors, I count at least 6, but it is very likely 8 or 10, and then additional channels for fun user interface features, like landing gear, real lift ramp, lifting hooks and winches, maybe a over head track that scoots parachute men out the back, lol.. either way, really cool!!!

Namoral quando começou o esse som achei que ia explodir, mas muito top

Nice Sound effect added

Thats some good engeneering but the Sound reminds me of the Sound that i hear when i start a 50 year old model-train

excellent ! La synchronisation des hélices est comme en vrai ^^

The engine sound is great

I’ve never enjoyed the start up of an Rc vehicle so much! This was really cool. Awesome choppa

Timing is very important.

Haha the high pitched whine is so indicative of riding in the CH-47

I thought it would fly 😂

Still one of my fav video on Rc Project... It would be nice if you upload the whole vid..😍😍

I wouldn’t stand that close I had a friend that got decapitated from a rc heli and it was devastating I know sometimes we get excited as humans but plz take extra precautions god bless and great video that heli is wicked

It's time to deliver the parcel to my neighbour.

What makes it more fascinating is that the propellers' rotation reverses their rotation after the spin

Lots of work and programing went into building this nice work man it's not easy to get rc heli props to spin proportional

Good job man you should design it as a military one

Los rotores corren en la misma direccion. Ya me imagino porque no se levanta! Dificil de controlar!

I was having anxiety when I was watching at the propellers😂🤣

May Allah bless you with his mercy, excellent brother 🌹

Amazing wind up 😮

Serious toy, who says it's for kids when us adults can have fun at show & tell.

Super bro love from tamilnadu ❤️

That's pretty rad!

Классно взлетел, так резко оторвался от земли и исчез за тучами! 😂

Damn it started like a train engine 👀

I love how the properler move protortionally without touching eachother

مجاهدون افغانستان الابطال مرغو انف امريكا في التراب ☝️☝️☝️☝️

Legends, Lords, people are waiting that Heli to fly and colide 💀

The original design was marvelous almost fastest and heavy load barrier whit super chance of success

Are the two axes mechanically linked?

That blades trick is amazing 😉

its not the blades that rises its the machine but the gyroscopes that raises it bladeds guilds it.gyro lifts blades flys it

Excellent example of hydrostatic action hydrostatic action is friction drag coefficient used as a transfer medium

Plot twist : that helicopter never flew 😂🤣

कैसी लगी वॉइस editing 😅👽

There will never come a day that the blades collide..? 😂

Excelente juguete, la pregunta es ¿Si Volará????

Your plane so wonderfull😍😍😂🚁

Sounds of me winding up in the morning to get out of bed and get the day going. 😆

Он так хорошо сделаны друг друга не задевают

Tôi đã nghĩ tới việc hai cánh quạt chung một động cơ 😂😂😂

When it's going to fly 🤔

Fly damnit, FLYYYYYY!!!

This is why it is called too short video.. 😂

Is the synchronization mechanically or electronically calculated? Do you have a video on that? As an fpv drone pilot, this is pretty cool.

Estou aguardando o seu voo até hoje....

I was waiting for the fabulous take off but it not happened 🙃

How the propellers didn’t touch made me consider life

Amazing blade combination without any accident
