Overview
The
E-flite 40A Pro Switch-Mode BEC Brushless ESC is a high-quality,
innovative and efficient sensorless brushless electronic speed control
with an integrated Switch-Mode BEC. It can operate without the need for
a separate receiver battery to power your servos and receivers, saving
you weight and complication. It is capable of up to 40 amps continuous
current when using 3- to 6-series Li-Po battery packs. You can drive up
to 7 analog or 6 digital standard-sized servos with the BEC on any
recommended input voltage. This ESC also features an exposed, finned
heat sink aluminum case with lightweight plastic endcaps. Additional
features include safe power-arming along with advanced programmable
features such as low-voltage cutoff, braking, timing, throttle input
range, and more, making this truly a ‘pro series’ speed control.
