HAKRC HK3220 32Bit 65A 2-8S 20x20 4in1 ESC

HAKRC’s BLHeli_32 3220 65A 4‑in‑1 brings big‑rig power to compact 20x20 builds, making it a killer option for aggressive 5" and hybrid racers who keep blowing up 30x30 stacks on punchouts. With 65A per channel on BLHeli_32 firmware and modern 32‑bit processing, it has the overhead to survive hot motors, heavy props, and repeated full‑throttle pulls in race conditions.

Key features

• 65A per channel 4‑in‑1 ESC with plenty of current headroom for modern 2207–23xx motors on 5" race rigs.

• 32‑bit BLHeli_32 firmware with hardware PWM for smoother throttle resolution, quieter operation, and full compatibility with DShot protocols.

• 2–8S input range (check your build and FC rating) so you can run everything from standard 6S race builds to experimental high‑voltage setups.

• 20x20mm mounting pattern with a compact 34 x 42 mm footprint to drop straight into modern slammed freestyle and race frames.

• High‑quality MOSFETs, thick multi‑layer copper PCB, and onboard capacitance designed to handle sustained load while keeping temps under control.

Performance and firmware

• BLHeli_32 feature set gives you access to 128k PWM, motor timing tuning, custom startup tones, and full telemetry support when paired with a compatible FC.

• Supports bidirectional DShot and RPM filtering when configured in your flight controller firmware, helping you run lower filters and higher P/D gains without desyncs.

• Damped light / active braking for crisp prop wash handling and faster throttle changes in tight tracks.

Build integration

• 20x20 mounting makes it a clean stack partner for lightweight F4/F7 race flight controllers or AIO conversions where you want a separate high‑amp ESC.

• Standard motor pad layout and clearly labeled signal/ground pads to simplify wiring and minimize build time.

• Designed for FPV racing drones, but with enough overhead to be at home in toothy bando bashers and compact long‑range rigs that need reliability over grams.

Ideal for Five33 builds

• Pairs well with high‑KV 6S motor options commonly used on Five33 race frames, giving you current capacity to spare on heavy gates and sketchy recoveries.

• Great choice when you want 30x30‑level durability in a 20x20 stack, especially in slammed builds where space and airflow are limited.
