K-max

[OLD_Astar]

I'm flying on a job that is using a K-MAX as well.I hear all kind of numbers for that machine.

6000 pounds on the hook easy,or others are saying 5000 pounds. Who's right?

Is it that good of a lifter? Anybody on the forum flying them?

I'd like to have "info"!!

OLD Astar - If you are working on the same job as the Kmax you could always duck across and say hi to the pilot and ask him

JacDor's numbers are about bang on with slight differences given to engine performance and Terrain.

As a note here, these numbers were taken from the Kaman Helicopter's Website.

Copied and Pasted here. I do not fly the K-Max

The short of the long of it - 6000 lbs no problem, with caveats.

 

Every aircraft will settle with power. The K 1200 Kmax will not experience Vortex Ring State due to the intermeshing main rotor design. But that's in my less than a gazillion hours of experience...
