30A Pro Brushless ESC (EFLA1030B)

The 30-Amp Pro Switch-Mode Brushless ESC with BEC is a compact, sensorless electronic speed controller designed for RC models that use brushless motors. It integrates a switch-mode BEC to power servos and receivers directly from the main battery, eliminating the need for a separate receiver battery and simplifying wiring.

It delivers up to 30A continuous current (35A peak for 15 seconds) and includes a 5V, 3.5A BEC, supporting 3- to 4-cell LiPo or 9- to 12-cell NiMH/Ni-Cd packs. Features include programmable motor braking, safe power-arm mode to prevent accidental starts, and a programmable low-voltage cutoff with options for 3S, 4S, or a percentage of starting voltage. Throttle range and soft-start can be tuned, and timing can be selected from five presets to match a wide range of brushless motors. Auto motor shut-down on signal loss or interference helps protect the model, and pre-wired EC3 battery input with 3.5mm bullet connectors on the motor leads.
