Eflite 25 Amp PRO Brushless Speed Controller

This controller has been designed for use in radio control aircraft and to support continuous currents of up to 25 amps when using 2-3 cell Li-Po battery packs and up to four sub-micro servos. The ESC features a lightweight plastic case, with exposed, finned heat sinks for both the motor drive mosfets, and unlike many controllers, the BEC regulators give you a more reliable and powerful power supply for your servos.

E-Flite 40amp PRO Brushless Speed Controller

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.
