From the Robinson website: The ROBINSON R44 RAVEN II POLICE HELICOPTER combines proven R44 performance and reliability with state-of-the-art law enforcement technology. Lower acquisition costs, lower operating costs and a simplified maintenance schedule make the R44 ideal for large and small police departments. The three-place R44 Police Helicopter features an aerodynamic fuselage that optimizes airspeed and fuel economy enabling the helicopter to remain on station for up to two and one-half hours. An open cabin design provides unobstructed views allowing for better tactical support, and a low tail-rotor tip speed, heavy duty muffler, and large cambered tail decrease flyover noise. The R44 Police Helicopter is turn-key ready, equipped with FAA-approved technologies that include an infrared imaging system, a fold-down monitor, a powerful searchlight, and a dual-audio controller. Down time is significantly reduced with a simplified maintenance schedule that requires only oil changes between 100-hour inspections.
