30-Amp Telemetry Capable ESC Apprentice STS

The E-flite 30 A Telemetry-Capable ESC (EFLA1030FB) is the upgraded speed controller for the Apprentice STS series. It brings real-time telemetry feedback to your setup—letting you monitor voltage and current directly from the transmitter. With integrated switch-mode BEC, programming flexibility, and solid protective features, it delivers both convenience and safety.

Features
