The E-flite® 30-Amp Pro Switch-mode BEC Brushless ESC (V2). This is a high-quality sensorless brushless electronic speed control with an integrated switch-mode BEC that is very lightweight and efficient. It can operate without the need for a separate receiver battery to power your servos and receivers, saving you weight and complication.
E Flite 30 Amp Pro Switching BEC Brushless ESC (Coated) (V2) Features:

• Up to 30 amps continuous current with proper air flow and 35 amps burst current (15 seconds)
• 3.5A continuous current, 5V Switch-Mode BEC Circuit
• Stronger BEC for support of most 3-axis stabilization systems
• Drive up to 7 analog or 6 digital standard-size servos with the BEC
• 3- to 4-cell Li-Po, 9- to 12-cell Ni-MH/Ni-Cd input voltage
• Programmable motor braking
• Safe power-arm mode prevents accidental starts
• Programmable low voltage cutoff with settings for 3-cell Li-Po (9.2V), 4-cell Li-Po (12V) or 74% of battery starting voltage
• Programmable throttle input range (1.1ms–1.9ms or 1.2ms–1.8ms)
• Programmable soft start for helis and airplanes
• Auto motor shut down if signal is lost or there is interference
• Programmable timing—5 user-selectable ranges for use with a large variety of brushless motors
• Pre-wired connectors—E-flite EC3™ connector on battery input and 3.5mm gold bullet connectors on motor output leads
