Scorpion SPCR15V25AESC 25A Brushless Aircraft ESC with 6V/2A BEC for 2-4S  [SPCR15V25AESC]

Setup and tuning notes for aircraft

The Scorpion SPCR15V25AESC is an electronic speed controller aimed at electric model aircraft, supporting 2S to 4S LiPo packs with a 25A continuous rating and including a 6V/2A BEC. It is intended to regulate brushless motor power and supply small servos and the receiver on light airframes.

Use this ESC with brushless motors and batteries that keep current draw under its 25A limit; the integrated 6V/2A regulator gives convenient power for typical radio gear. Plan servo allocation and power demands so the BEC is not overloaded, or provide an auxiliary power source when using several high-current servos.

Wiring tips: observe correct polarity, secure all connections, and position the ESC where airflow can assist cooling during longer flights. Isolate the unit from sharp vibrations and route motor leads to minimise interference with signal wiring and onboard electronics.

Throttle and programming: set throttle endpoints, cutoff voltages and any braking or governor functions using the appropriate programming method for this ESC family. Test servo response and BEC stability under working loads, then refine settings for the best throttle feel and safety margins.

A compact option for pilots needing a 25A ESC with a 6V/2A BEC suitable for many 2-4S aircraft installations.
