N514JD —

Part of the Fresno Police Department Skywatch Unit. This one makes this creepy, noticeable sound made by its tail propeller that often gives me the chills and lets me know that something is going on. Could be due to the fact that the sound is often noticeable when the EC20 is circling around an area. N514JD often tends to be out at night.

The tail rotor on this model is called a Fenstron(r) which is much quieter than a conventional tail rotor. This would account for Bradley's description of the "creepy" sound. But this helicopter is ideal for night work simply because it is MUCH quieter due to not only the Fenestron(r) tail rotor but also the fact this has a 3-bladed main rotor (vs 2-bladed).
