The US Army's gotten a good deal out of the Eurocopter 145, redesignated as the LUH-72A Lakota. Nevertheless, my transition from the UH-60 Black Hawk to the Lakota has had a few bumps.
Of course, there are the obvious differences between the UH-60 and the LUH-72; the Lakota features a glass cockpit and skids, while the L-model Black Hawk still has old-fashioned "steam" gauges and wheeled landing gear.
But there are a few minor differences that take some getting used to. Fitting for a helicopter company that builds most of its products with a clockwise-rotating rotor system, the pilot's door handle rotates in the opposite direction as that of the Black Hawk, which is cause for some facepamingly-bad embarrassment.
(Mercifully, the LUH's main rotor system rotates in the "right" direction, so I don't have to bungle through putting in right pedal and right cyclic on takeoff)
There's also the curious design quirk of an engine throttle which works in the opposite direction as that of the Bell 206 JetRanger, the US Army's training aircraft during the initial stages of flight school. What has two thumbs and nearly shut down an engine instead of starting it? Oh yeah, this guy.
