Holybro Tekko32 F4 4-in-1 50A ESC AM32 4–6S

Product description

The Holybro Tekko32 F4 4-in-1 50A ESC AM32 is a modern, high-performance ESC designed for demanding FPV racing and freestyle drones. Equipped with an extremely fast 150 MHz F4 microcontroller, modern AM32 firmware, and PWM frequencies up to 96 kHz, this ESC delivers exceptionally precise motor control, ultra-fast response times, and a particularly smooth flying experience.

Compared to older F0- or F3-based ESCs, the Tekko32 F4 operates significantly faster and more efficiently. This is particularly noticeable during aggressive freestyle maneuvers, rapid changes in direction, and precise throttle control. Small signals are processed with virtually no delay—like a hyperactive squirrel on espresso, but channeled in a technically sound way.

With 50A continuous current per channel and support for 4–6S LiPo batteries, this ESC is perfectly suited for powerful 5-inch builds and modern high-performance FPV setups. Support for DShot1200, ESC telemetry, and an integrated analog current sensor ensures maximum control and optimal tuning in Betaflight or other flight controller systems.

The separate drive and control circuits reduce electrical interference while improving the motor control’s resilience. The result is more stable and efficient operation even under heavy loads.

Thanks to its compact 30.5x30.5mm standard format, the ESC can be easily integrated into numerous FPV frames and fits perfectly with modern racing and freestyle builds.
