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.
Up to 40 amps continuous current with proper air flow and 55 amps burst 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.
