Here is a brand new in the package Castle Creations Phoenix HV-45 ESC. 45 amp High Voltage Brushless Sensorless Speed Control. I purchased this item new and never got around to using it and no longer have a use for it at the moment. A new high-voltage brushless ESC for use with up to 36 NiCd/NiMH or 12S Li-Poly cells. At 45 amps continuous, it can supply over 2000 watts of power to your large brushless motor. Most features are programmable via the transmitter or using a computer and the PHX-Link USB Programming Device.
