Description
The E-flite 40A Pro Switch-Mode BEC Brushless ESC (V2) is a high-quality, sensorless speed controller with an efficient 5V/2.5A switch‑mode BEC. It can power your receiver and servos without a separate pack, helping to reduce weight and complexity. Supporting 3–6S Li‑Po or 9–18 cell Ni‑Cd/Ni‑MH, it delivers up to 40A continuous current with proper airflow and 55A burst for 15 seconds. A finned aluminium heat sink case enhances cooling, while comprehensive programming and safety features make it a versatile choice for fixed‑wing and heli applications. Part number: EFLA1040B.

Specifications
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.
