I had a look on wiki, the K-Max (as mentioned in OP) is the twin rotor one = I'd love to see one with a wrecking ball

From wiki'''

The K-MAX relies on the two primary advantages of synchropters over conventional helicopters. The first of these is the increased efficiency compared to conventional rotor-lift technology; the other is the synchropter's natural tendency to hover. This increases stability, especially for precision work in placing suspended loads. At the same time, the synchropter is more responsive to pilot control inputs, making it possible to easily swing a load, to scatter seed, chemicals, or water over a larger area.

A K-MAX has been used for demolition work by having a wrecking ball as a slung load.[7]
