This is the E-Flite 10-Amp Pro Brushless ESC.  This is a high-quality speed control for 6-10 NiCd or NiMH cells, or 2-3 cell Li-Po setups.

Key Features

• Up to 10 amps continuous current with proper air flow
• 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—JST on battery input and 2mm 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 10 amps when using 2-3 cell Li-Po battery packs and up to four submicro servos. Standard features include advance BEC and safe power arming along with programmable features such as low voltage cutoff, braking, timing, and throttle input range.
