Coaxial helicopters like the KA-50 use differential torque to control yaw. Each of the two rotor systems spin in opposite directions which keeps the torque/yaw force balanced, so to yaw in one direction the helicopter delivers more torque to one of the rotor systems causing the helicopter to spin/yaw the opposite way. The K-Max, Chinook and other tandem rotor helicopters use differential cyclic pitch to control yaw, but again both rotors spin in opposite directions for balance.

gotta love the skill involved here floats a multi tonne machine above the ground like it was a natural as walking.

It was painted per customer order. This one was was brand new and had not yet been delivered to said customer, which is why it also had the N-number based on the country of manufacture.

I have no practical experience flying tandem or coaxial rotor helicopters. They don't need constant anti-torque adjustments but I'm sure have some of their own control challenges. Coaxial helos tend to be heavier because they have twice as many rotor hub and transmission components, more complex mechanics, beefier mast, etc. which reduces their useful load carrying capacity. But nearly all the horsepower is applied to lift-producing rotors, and tandems like K-Max and Chinook can lift a lot!

@jbrain93 Nope, no tail rotor. It uses the NOTAR system, which manipulates airflow over the tail boom for anti-torque, and sends a jet of air through a rotating nozzle on the end of the tail boom for yaw control.

Since the two rotor disks are spinning in opposite directions, all of the torque that would require a tail rotor is canceled out. For yaw control with two rotor systems, you can either tilt the rotor disks in opposite directions (how it's done in the Chinook and Osprey), or you can increase collective pitch in one set of rotors and decrease pitch in the other, causing an imbalance in torque force; the helicopter will yaw in the direction of the rotor disk producing less torque.

Nice looking machine

It has a system called NOTAR that replaces the tail rotor.

awesome video

magnifico

These things are beautiful! Where can I buy one in black? ; )

Are dual rotor helicopters easier to fly than the tail rotor style? Any drawbacks to the dual rotor?

@cepv09 What makes you say that the Kaman K-Max is more quiet? Do you have any evidence?

The purrrrr

hahah, one certainly hopes not! The flag was on the compressed air canister for the skid floats and the ship was brand new (still registered experimental), so I imagine it was a reminder to not try operating the floats. Nice eye!

Do you know about the dual rotor helicopters? Such as the KAMAN K-MAX and some other Russian helicopters.. how do they operate since you don't have one force overpowering?

But it should operate the same as a tail rotor heli?

Did he just moonie the camera man @ 0:24 great video nice chopper too.

Well in real life this helicopter has lesser noise compared to a UH-1.

its really quiet.

Io c'ero su questo!!!!!

Sou obrigado compra um avião desses!

Which place is this

Yep, same controls and all.

does it not have a tail rotor? or am I blind?

It’s an internal system. This helicopter is fucking top shit

im sure anyone would fly like that if they had loads of flight hours

Show off!

wow, what a show off, lol. good pilot, great video.

What's the deal with Jordan Flag and Arabic?
