Product Description
Elevate your next FPV build with the Fly Spark BLS 80A 4-in-1 ESC—a precision-engineered electronic speed controller that packs four independent 80 A channels into a single 30.5 × 30.5 mm board. Built around the ultra-responsive EFM8BB21F16G MCU and high-performance MOSFETs, it delivers up to 80 A continuous current per motor (90 A bursts for up to 10 s) while weighing in at just 28 g. Whether you’re racing, freestyling, or pushing the limits of cinematic flight, the Fly Spark ESC’s DSHOT300/600 digital protocol, 200-scale current sensor, and optimized Q_H_40_24_v0.19.2 firmware ensure rock-steady throttle control, accurate telemetry, and minimal latency—so you stay in perfect sync with your pilot inputs.
