Ka-27PS Helix


Recommended Posts

This is Zvezda's Helix kit, with slightly altered decals.  A straightforward build "out the box" for my first real completion of 2020.

Very clean and neat Kamov representation!

 

The design, while it may look unwieldy, has a number of advantages over the conventional helicopter form factor. For one, there's no tail rotor to walk into on board a crowded flight deck. More important, the coaxial, contra-rotating principle makes the Kamovs inherently stable and much less sensitive to gusty wind conditions.

 

Kind regards,

The co-axial system also means that all the power goes to the main rotors - rather than a percentage having to be used for an anti-torque tail rotor - which is why the Kamovs are much used in the logging industry.

 

One disadvantage is the height of the rotor mast (to keep the blades separate) - one of the reasons that the Mi-28 won out over the Ka-50 - the latter could not fit inside an Il-76 without the rotor mast being totally dismantled....

 

Great model BTW :worthy:
