You wouldn’t notice if you didn’t know and weren’t looking for this, but the S61 in the hover is very slightly left wheel low. Watch as it lifts off, and the right wheel lifts off just before the left wheel. This is due to a design feature in the flight controls. All helicopters have a device called a mixer unit, which mechanically combines the cyclic and collective controls to set the position of the swashplate and the rotor disc. The S61 has an additional mixer unit function that links the collective control to the yaw control. As the collective is raised, the main rotor shaft torque will be increased, and the link from collective to yaw automatically increases the tail rotor pitch to compensate. This has the effect of producing a sideways force on the aircraft that would cause a sideways drift. As the collective is raised, the swashplate rises slightly more on the right hand side than on the left, to produce a sideways force to compensate for the effect of the tail rotor. The result is that the rotor is tilted slightly to the left, causing a left wheel low hover. The Sea King has the same behaviour. Smaller rotorcraft don’t need this feature, but tit is common on Sikorsky designs
As an offshore worker in the Dutch part off the Northsea, I regularly flew with the S61, From Den Helder airport to locations offshore. until they were taken out of service in 2010.
Nice footage of the mighty S-61 firing up and taking off, that's an impressive helicopter! This one was in Nelson a few weeks ago but I never managed to get any footage of it.
Very nice video of a great helicopter! From a helicopter photographer's perspective, the only thing I did not like was that ground crew member standing in the way in the best moments of the lift-off :)
I worked at Big White last season i was never knew how many great aircraft you had down at Penticton airport. if I knew and if I stayed for the summer would of loved to see some of the cool stuff we don't get on Australia
The helicopter is set up for firefighting. It carries a large tank used to hold water, (the rectangular object attached to the belly.) So they will go hover over a lake and pump water into the tank using the hose. Once over the target, they open a dump valve on the tank. You can see a black circle on the backside tank once they lift off and turn, that would be the dump valve. There's a myth that a scuba diver was sucked up by filler hose from a firefighting helicopter then dropped in a tree. Mythbusters did an episode about that. See season 2 episode 3.
@@Amtjohn5150 I think you have the wrong episode there mate, I remember seeing that episode a LONG time ago, I just checked up on it, and it's about the marching on the bridge, the rowboat skiing, and the toothbrushes.
I have seen a helicopter land in the Philippines at a military camp during Marawi siege and i heard the real sound of it landing but now i can hear how it starts up.
That's s a water hose, this helicopter is for fire departments use. The hose sucks the water from any close by source of the fire, could be river lake water reservoir even a pool. Fills the tank and droops thousands of gallons/ liters.
I was a mechanic on a french army medium size helicopter, SA330 Puma (Oh yeah!!!). The rotors are locked for startup when there is too much wind. Why? Because of strong wind you need to control the blades right away, even for very slow rpm. But I don't see any wind...
No 1 engine will running 100% for hydraulic and generator, power supply will disengage and generator will take place. and then the no 2 engine start until 50% and will rise until 52% and then the rotor brake will off the rotor blade will turn. Ssl will apply no 2 engine with 100% if all reading stable and then no 1 engine will going to 50%. This point the linear actuator will flight and the engine no 1 and 2 will pair n share load and keep advancing no 1 to 100% and it will safe for flight.

Thanks for sharing I own and operate 3 Sikorsky S61N for firefighting in korea
0: Whoa
You can't operate them all at once
@@leonvdm of course you can, just use as many crew as needed.
Awesome
Very cool!

Amazing footage of this impressive Sikorsky S-61. Huge like!
Thanks a lot!

Isn't Kootenay Valley Helicopters based in Nelson?
@@VMCAviationVideos Ya, they're based here. But they don't have any of their S-61's here. I'm not sure where they have them based.
Looks like it’s in Penticton, CYYF.
@@loadie150 Sure is

Ohh yes
Awesome video. That's one neat looking S-61!
It sure is!
That's a beautiful helicopter
Yes it is
Thank you for sharing this footage. Nice idea with the timeline !
Glad you liked it!

We only get them when there is a wildfire nearby. Are you coming back this coming winter?
what's that hose sticking down from it?

Great video

Jeeze I thought that hose was for fuel or something and that they weren’t gonna disconnect it lol
Haha, no
As a Helicopter Mechanic.. I love seeing these video's!! Keep up the GREAT work good sir. 👍👍

Wait.. did he just take off with the petrol hose still in his tank??

No suction hose for water
Um, That's how you know it's a boy helicopter...
Haha, NOPE
Haha, Yes
Great video my friend 😀🙌👋

Anybody know why the rotors are locked for startup?

Would stopping the blades from turning with the engines running cause damage to the power turbine from the heat?
@@sanfranciscobay pass a certain point, i guess it could.
No 1 engine will running 100% for hydraulic and generator, power supply will disengage and generator will take place. and then the no 2 engine start until 50% and will rise until 52% and then the rotor brake will off the rotor blade will turn.

T58 ge engine? I worked with s61a-4.
Stater motor start ng rise until 20% if below that the pilot will smash the dashboard. Haha
