Product overview
The HAKRC 4279 14S 80A Airplane ESC is a monobloc electronic speed controller for fixed-wing aircraft. Its specified size is 59 × 43mm and its net weight is 63g, defining the component’s space and mass requirements for installation. It accepts 6S–14S LiPo input and incorporates a BEC specified at 5V, 8A, with a 15A maximum. Control interfaces include PWM, Oneshot125, Oneshot42, Multishot and Dshot150/300/600, with HAKRC-AT4G-Rev.32.9-MUlti firmware specified for the controller.
The electronics combine an AT32F421K8U7 processor running at up to 120MHz with three SLM21867 drivers and parallel 80V MOS devices. A six-layer PCB with 2oz copper, resin-plugged construction, metallized edging and added copper strips forms the current-carrying architecture. Japanese Murata capacitors provide filtering, while an industrial-grade DC-DC converter is described as resistant to high temperatures. The continuous-current specification is 80A under a closed-incubator test lasting 41 seconds; peak current is 100A. That stated test duration is a material qualification when sizing the aircraft’s propulsion installation.
