I don't think they ever intended it to be 3.5 hrs at MGW or at MCP cruise. Nominal GW-CG and lower torque setting/speed and you get much better numbers. To get 3.5 hours of endurance you need fuel flow of around 150 pph and a short startup and takeoff way below TOP. I've seen those kinds of numbers in other light Heli's at low power settings. But who cares... 3.5 hours is too long for most bladders anyway.
