Analysis

The plt reported that during takeoff from a county road (elevation 5500 ft), he allowed the RPM to drop 'below green.' Reportedly, he had a choice of either setting the helicopter down on the road or flying down a slope to gain airspeed. He elected to land on the road. However, the rotor RPM had slowed to the point that the helicopter touched down hard & the rotor blades struck the tail boom. The density altitude was aprx 8000 ft. no mechanical engine malfunctions were reported.
