  • 40-Amp Lite Pro Switch-Mode BEC Brushless ESC (V2)

    The E-flite® 40-Amp Lite 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.


    • 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 on any recommended input voltage
    • 3- to 6-cell Li-Po, 9- to 18-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), 5-cell Li-Po (15V), 6-cell Li-Po (18V) 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, use with a large variety of brushless motors
