Scorpion SPCR15V25AESC 25A 6V/2A BEC Brushless ESC for 2-4S Planes and Helis  [SPCR15V25AESC]

Compact 15V 25A ESC for RC aircraft

The Scorpion SPCR15V25AESC is a purpose-built RC-scale electronic speed controller for electric model aircraft, specified for 2-4S LiPo operation with a 25A rating and an integrated 6V/2A BEC. It is designed to deliver steady current to brushless motors while powering servos and receivers on lightweight planes and helis.

Compatibility is governed by the ESC rating: it supports 2S to 4S LiPo packs and brushless motors that stay within the unit's 25A limit. The built-in 6V/2A BEC supplies a regulated voltage for common radio gear, but you should ensure combined servo draw stays inside the BEC capacity to avoid browning out the receiver.

Installation notes: observe standard RC wiring practice, keep battery and motor leads as short and secure as practical, and confirm correct polarity when connecting the receiver and servos. Mount the ESC where airflow can help cooling during long runs, and use suitable rubber mounts or isolation to reduce vibration. Keep motor wires separated from sensitive signal wiring to minimise electrical noise.

Tuning and setup: this ESC manages throttle response and motor output for your airframe. Use compatible programming tools to set throttle endpoints, braking if needed, and low-voltage cutoff tuned to your chosen LiPo cell count. Check servo movement under load and verify the BEC holds steady voltage during higher throttle draws.

For pilots upgrading or replacing an ESC on a small plane or helicopter, this unit supplies a compact 25A capacity and a 6V/2A BEC suitable for many 2-4S LiPo builds.
