K-Max Titan Helicopter
The K-Max transport sky tractor of Kaman (USA) has a difficult fate. His first job in 1994 was logging, where, thanks to his unusual design with crisscrossing rotors (synchrocopter), he successfully performed the functions of a flying crane, transporting up to 2.7 tons of wood at a time on an external suspension.
For reference: the K-Mach synchrocopter does not have a tail rotor, the engines are located next to each other at a slight angle, and the blades rotate in opposite directions, without intersecting with each other and providing lift. This arrangement guarantees more efficient power usage and simplifies maintenance.

Then there was the service in Afghanistan. There, K-Mach performed missions (including unmanned ones) to deliver cargo for the US Army. It is worth clarifying that there is both its manned (pilot + mechanic) and unmanned version-K-Max Titan. Last week, the "civil" flight of the K-Max Titan took place as the world's first heavy unmanned helicopter designed for commercial purposes. The Titan system will soon be available as a retrofit for K-Max helicopters, as well as an option for new rotorcraft.
