ZTW BX 60A 4-in-1 AM32 ESC 3S-6S 8 Layer PCB for 7–10 Inch FPV Freestyle Drone

The Sweet Spot for 5–7 Inch Freestyle

The 60A 4-in-1 is the workhorse of the BX lineup, engineered for 5–7 inch freestyle, racing, and all-rounder quads. With 60A continuous and 80A burst per channel, it handles 6S setups with 2207–2507 motors comfortably, with headroom for aggressive throttle punches.

120MHz AT32F421 + Bidirectional DSHOT

The 120MHz AT32F421 MCU processes bidirectional DSHOT300/600 telemetry in real time, feeding RPM data to Betaflight for adaptive noise filtering. The result: cleaner gyro data, lower filter latency, and a more connected flight feel — critical for tight racing lines and technical freestyle.

4kg Payload Capacity for Light Commercial Use

Beyond hobby flying, the 60A is rated for multirotor platforms up to 4kg total weight — suitable for lightweight inspection, mapping, and small delivery drones. The 30.5×30.5mm/M4 mounting standard fits virtually every mid-size flight controller stack.

AM32 Firmware, Web-Configurable

Open-source AM32 firmware means community support, frequent updates, and a simple web interface for tuning motor timing, acceleration, and braking. Default settings are optimized for 5–7 inch freestyle — flash and fly.

Robust Power Stage

A 2200µF bulk capacitor, 12AWG power leads with Amass XT60, and dual 8Pin SH1.0 FC connectors ensure clean power delivery even during full-throttle 6S dives. At 16g and 42×41×6.5mm, it stays compact for tight builds.
