This 120V ESC has a maximum continuous current of 120 amps. Similar to the other Phoenix Edge ESCs, this speed controller features an auxiliary wire which you can be easily programmed. This white auxiliary wire can be used for a wide variety of functions. For example, you can use it to adjust the helicopter governor gain mid-flight. It can serve as an audible beacon in the event of an unexpected landing. If you have a 3-axis gyro that supports RPM sensors, the wire can act as an RPM output. Additionally, it can be used as an arming lock for your ESC (Castle Creations have included a coupon for a free Arming Lockout Key with the Phoenix Edge 120). Furthermore, the wire can be used as a receiver arming lock.

The versatility of the Phoenix Edge 120 is clear. When coupled with its data logging capabilities, you can see why it is a valuable component in your model. What’s more, the Edge 120 comes with USB programming capability through Castle Creations’ Castle Link USB adapter (again, a coupon has been included with the Edge to give you free access to this service). This Castle Creations ESC is a great choice for your 450- to 800-size RC helicopter or fixed wing model (1.20-size and above).
