Keep your FMS ASW-17 2500mm soaring with the genuine FMS 40A Predator ESC (Part No. PRESC034). This is the exact electronic speed controller fitted to the ASW-17 from the factory, so you get guaranteed compatibility, correct throttle calibration, and the smooth power delivery your glider was designed around — no guesswork, no adaptors.

Built around a solid 40A continuous current rating, this brushless ESC handles the full power band of your ASW-17's motor with cool, reliable performance flight after flight. Its standout feature is the active brake function: the moment you throttle down, the ESC stops the motor so the folding propeller folds flat against the nose. That means dramatically less drag, cleaner glide angles, and the long, quiet thermal hunts the ASW-17 is built for.

An integrated BEC supplies clean power to your receiver and servos, and the ESC ships with FMS-standard connectors for true plug-and-play installation. Whether you've damaged your original unit, want a tested spare in the field box, or are rebuilding after a hard landing, this is the straightforward, dependable replacement that gets you back in the air fast.
