Zerodrag Boost AM32 55A 4-in-1 ESC

The Zerodrag Boost AM32 55A 4-in-1 ESC provides high-amperage power delivery for 5-inch freestyle, racing, and heavy-lift cinelifter builds. Designed and manufactured in India, this ESC runs on the open-source AM32 firmware, which optimises motor synchronisation, active freewheeling, and telemetry feedback. With a 55A continuous current rating, it effortlessly manages aggressive throttle inputs and modern high-KV motors without dropping sync.
