Castle Creations Phoenix Edge HV 60 AMP ESC, 12S / 50.4V, no BEC Radio-Controlled (RC) model part/accessory

THE AUXILIARY ADVANTAGE!
Phoenix Edge Series ESCs are the next evolution in speed controller technology. The white user-programmable auxiliary wire can be used for features such as helicopter governor gain input adjustments mid-flight, serving as an audible beacon after an “unexpected landing”, acting as an RPM output for 3-axis gyros that support RPM sensors, be used as an ESC arming lock (coupon for free Arming Lockout Key included), or as a receiver arming lock. Combined with data logging, access to Castle's industry leading software functions, and USB programming capability via Castle Link USB adapter (coupon included) or the Castle Link iOS App and a B-LINK Bluetooth Adapter, Phoenix Edge offers unparalleled versatility.
