Sikorsky S-61 from Engine start to Lift-off and Departure 

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

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

Thank you for sharing this footage. Nice idea with the timeline !

Awesome video. That's one neat looking S-61!

Those are big beautiful beasts!

HELLO......wonderful video. Best greetings from Switzerland

Thanks for sharing I own and operate 3 Sikorsky S61N for firefighting in korea

Thank you everytimes.

Great video my friend 😀🙌👋

Excellent video my friend 😍👌

Nice catch

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.

Great video

Bellísima máquina 😍

That's a beautiful helicopter

Excelente muchas gracias saludos de colonbia

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

4K and a Sikorsky..... nothing better!!

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 :)

As a Helicopter Mechanic.. I love seeing these video's!! Keep up the GREAT work good sir. 👍👍

Jeeze I thought that hose was for fuel or something and that they weren’t gonna disconnect it lol

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.

Fascinating to see

Looked like Coby from Rotor Maxx Support

👍

Sounds kinda like a S76. Guessing it is the same tail rotors are used for the S76 and S61. Right?

what's that hose sticking down from it?

Looks like a Carson rebuild.

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

Anybody know why the rotors are locked for startup?

The dude in the orange jumpsuit looks like a cgi render

They forgot somthing on it

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
