E-Flite EFLA1040B 40 Amp Pro Switch Mode BEC Brushless ESC V2

E-flite 40-Amp Pro Switch-Mode BEC Brushless ESC (V2) 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.

Features:
Up to 40 amps continuous current with proper air flow and 55 amps continuous current (15 seconds)
5A continuous current, 5V Switch-Mode BEC Circuit (Proper cooling and airflow required)
Stronger BEC for support of most 3-axis stabilization systems
Drive up to 7 analog or 6 digital standard-sized servos with the BEC
3- to 6-cell Li-Po, 9- to 18-cell Ni-MH/Ni-Cd input voltage
Finned heat sinks
Programmable motor braking
Safe power-arm mode prevents accidental starts
Programmable low voltage cutoff with settings for 3-cell Li-Po (9V), 4-cell Li-Po (12V), 5-cell Li-Po (15V), 6-cell Li-Po (18V) or 70% of battery starting voltage
Programmable throttle input range
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 to use with a large variety of brushless motors
Utilizes new smaller Mosfet technology to minimize weight
Radio System Power ON /OFF Switch
Prewired connectors—E-flite EC3 connector on battery input and 3.5mm gold bullet connectors on motor output leads
