Great video, thanks for not spoiling it with music.

[@followme-helitechnicaldataint]

There are helicopters, especially older models were there is no need for music 🤣👍

[@leneanderthalien]

Die Kamov sind zwahr mekanisch zimlich kompliziert , haben aber ein geringer rotor diameter und die stationnäre flugstabilität ist hervorragend, das ist warum viele schwehr flugarbeitsmaschinen Kamov sind...(ex: Heliswiss...)

[@servicarrider]

What a wonderful little helicopter. You wouldn't think that this would be cost effective but amazing to watch, none the less.

[@chpatriot9878]

little ?? oh yes....little and strong..!!

[@briansmobile1]

You have to approach these from the front due to the rotor angling down to the side and the fins on the back. Notice how the pilot lands with the maintenance/fuel guy at the nose at 6:12 .

[@josephvanwie6706]

Wonderful video of an awesome machine. What's just as amazing is someone paying two to three thousand dollars per hour for tree removal and that doesn't include the guys on the ground. The price per room for the hotel must be astronomical as it seems they are the ones paying for the logging. But I thank you for the video and it was enjoyable.

What a fantastic helicopter. I love it.

Великолепный вертолет , при своих размерах , он делает большую работу...., эксплуатируется по моим расчетам лет 40 ..?. ,падал из - за сильного ветра раза 2.....

[@detha123456789]

what are those things near the end of the blades and why do the blades look slightly offset

[@SoftwareExplorer]

briansmobile1 It's standard practice with most helicopters (not just this one) to approach from the front (so the pilot sees you). This one it's just especially important to not come from the side because you might get your head taken off, but probably significantly less dangerous to approach from the back than other helicopters, as there is no tail rotor (only a rudder flap which is unlikely to injure you).

[@morrisdennis]

I will approach from the side, whatever i do what i want!

[@BassdriveDragon]

Those are called Fletner Flaps or Servo Tab (check wikipedia) they are used to actually control the helicopter and not as TheBreacherAngi1993 said to reduce the sound.

[@scottrider3199]

Je l ai vu à Aigle (VD) aussi de Rotex hélicoptère. Et en vrai il est vraiment impressionnant

[@donjose4656]

Vidéo très intéressante...je vois que cet hélico utilise le même système de rotors que les Kaman ou Kamov russes.L'important est que ce soit fiable...Merci pour le partage !

[@pierreenglebert4278]

Pour votre info, Kmax est un modèle Kaman quand à Kamov, ceux-ci utilisent une technique différente à savoir deux rotors contra-rotatif coaxial.

[@charliemarren8724]

Correct. The reason the K-Max is much more quite then most helicopters is because it has no tail rotor blades. The tail rotor makes most of the noise on helicopters.

[@eds6889]

Charlie Marren ... almost correct, it’s the sound waves from the main rotor and tail rotor interacting that makes the higher levels of noise. Main rotor blade tips also make a lot of noise and are being designed to not have the same vortices.

[@TheBreacherAngi1993]

those things minimize the "flap flap flap" noise of the rotorblades. What dou you mean with "slightly offset"? the V-form of the axes`?

[@777DEHME]

beautiful video crazy heli engine they look like gonna hit each other.

the pilot is in tune!

Nice job, what weight can it lift?

[@nicozogg6419]

@Ace Tree Management 2700kg

[@morrisdennis]

About 6k

Woha die Qualität ist sooo "crispy". Was für'ne Kamera?

[@mickcarson8504]

Okay, what are they going to think of next? What's the purpose of this twin rotors?

[@EpicWaterDrop]

More lift and power, this is a heavy lift helicopter.

[@eds6889]

Mick Carson ... also it eliminates an anti torque system; a tail rotor, fenestron, or NOTAR. Plus this design of main rotor cannot get into vortex ring state.

[@MegaPypkin]

без перспективная модель, наши военные от такого отказались еще в 80-е года, так как очень ненадёжная конструкция и пришли к другой конструкции что используется в России на вертолётах серии Камова, К-52 "Аллигатор"

Ace Tree Management Capacity: 6,000 lb (2,722 kg) external load

[@alexo3720]

how well can these things autorotate? and how easy can you get into settling with power?

[@SoftwareExplorer]

According to a document explaining the design from the manufacturer, these have blades with significantly higher inertia than most helicopters. That lets you store more energy in the rotor system during an autorotation, and gives the pilot a little bit more time to react in a loss of power situation.

[@eds6889]

Alex o ... it cannot get into vortex ring state.

[@sharkamov]

The American made Kaman K-MAX is a great utility helicopter with a max external load capacity of 2,700 kg. (In comparison, the Russian Ka-32 BC11 & A12 has a max external load capacity of 5.000 kg, also an aircraft employing contra-rotating rotors via twin coaxial rotor masts, as opposed to the K-MAX's twin intermeshing rotors).

[@anibler]

Yeah but the KMAX is a much smaller aircraft, only weighing 2300kg, and able to lift 2700kg. The KA-32 weighs 6600kg.

[@abitofapickle6255]

They should make medical versions of this..lifting 6000 pounds of medical gear

[@leneanderthalien]

Der Kaman hat keinen frachtraum: es is ein purer fliegender krahn (und zimlich gefärlich fur das bodenpersonal wegen den tief herabragende rotor blätter), und seine nutzlasst is nur 2722kg am haken, der KA32 hebt 5000kg am haken und hat ein grosser frachtraum und hat so viele möglische verwendungen= diese 2 hélis sind gar nicht in der selbe kategorie...

[@SEThatered]

DIe sind aber doch weniger effizient im Vergleich zu Kaman (Leergewicht zu Vollgewicht Verhältnissweise). Die Ursache, dass Kamov so verbreitet ist liegt in dem Preis: Kaman ist viel viel teuerer. Doch jeder darf auch seine Favoriten haben, und deswegen wir können uns einigen, dass beide Hersteller machen hervorragende Maschienen.

[@tazanteflight8670]

How does it turn left or right. It cant use the difference in rotor speeds.... so what?

[@tazanteflight8670]

@@tekrit3249 Like I said, you cant do that in a meshing rotor situation. They have to rotate at the same speed or they will collide. You cant input more energy into one, and not the other. There is some other system turning this helicopter.

[@tazanteflight8670]

@@tekrit3249 If that was true, the vehicle would roll, not yaw. You cant change the pitch on only one rotor, and not produce roll. You also cant increase pitch to increase drag,... without producing lift. Again,... you can NOT change individual rotor speed. So no,.. your theory isnt correct. Anyone else?

[@tazanteflight8670]

@@tekrit3249 You havnt gathered, enough... to explain it....

[@tazanteflight8670]

@@tekrit3249 In your text, it says "causing the helicopter to turn and ROLL to the left." So I guess they just accept the roll. This is not a good solution. A quadcopter can yaw, without roll or pitch. You couldnt make this helicopter into a passenger vehicle, for example.

[@tazanteflight8670]

@@tekrit3249 Ya, I love this design. I like how the whole thing wobbles at rotor startup. I think it is funny how they made it tall, so they could get some reasonable, say 6 foot rotor clearance, on the side of the vehicle, because you cant teach humans new tricks. Someone would get lobbed. The whole design is funny. Watching it work is amazing. i cant look away.

Tja doch Kamov ist ein "bisschen" komplizierter als Kaman. Ich mein Hydraulik und Differenzial allein sind schon kompliziert, dazu kommt es mit enem "konventionellem" Steuerungsystem... Kaman hat dagegen Zugseilsystem und "controlflaps". Einfach aber genial meiner Meinung nach.
