It looks like Kaman have been flying unmanned helicopters for quite a few years now!
Kaman HTK-1K - the first unmanned helicopter (1953) - YouTube
It is surprising to read how few of these helicopters have been built thus far. The K-Max goes up against the Boeing H-6U in February next year for the Marine Corps' unmanned helicopter contract. Maybe the production line will be re-opened after that. Maybe future commercial sales of the K-Max are affected by the availability now of the Kamov KA-32.
