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-size servos with the BEC on any recommended input voltage. This ESC also features an exposed, finned heat sink aluminum case with lightweight plastic end-caps. 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.
