This is the E-Flite 25-Amp Pro Brushless ESC.  The 25-Amp Pro Brushless ESC features Advance Programming and Heat Sinks with a pre-wired EC3 Connector and battery input, as well as 3.5mm female gold bullets on the motor output leads.

Key Features

• Up to 25 amps continuous current with proper air flow
• Finned heat sinks for both the motor drive mosfets and dual BEC regulators to support up to 4 sub-micro servos
• Programmable motor braking
• Safe power-arm mode prevents accidental starts
• Programmable low voltage cut-off with settings for 2-cell Li-Po (6V), 3-cell Li-Po (9V) or 70% of battery starting voltage
• Programmable throttle input range (1.1ms-1.9ms or Auto Select)
• Auto motor shut down if signal is lost or there is interference
• Programmable timing—2 user selectable ranges for use with a large variety of brushless motors
• Pre-wired connectors—E-flite EC3 on battery input and 3.5mm female gold bullets on motor output leads
• Soft start

Overview

This controller has been designed for use in radio control aircraft and to support continuous currents of up to 25 amps when using 2-3 cell Li-Po battery packs and up to four sub-micro servos. The ESC features a lightweight plastic case, with exposed, finned heat sinks for both the motor drive mosfets, and unlike many controllers, the BEC regulators give you a more reliable and powerful power supply for your servos.
