Product overview
The HAKRC 2195 14S 120A Airplane ESC is an electronic speed controller for airplane propulsion integration. Its physical architecture stacks separately designed control and power boards within a specified size of 81*51mm and a net weight of 63g. The power board uses an eight-layer PCB with 2oz copper, resin-plugged construction and copper strips. Its electronics include an EFM8BB21F16G controller running at up to 50MHz, three SLM21867 drivers, 80V MOS devices in a quadruple-parallel arrangement, and Japanese Murata capacitors.
Electrical integration supports a 6S-14S LiPo input and PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300 and Dshot600 control protocols. The specified firmware is G-H-40-Rev-16.7-MUIti. Included functions comprise real-time bus-current sensing and an adjustable BEC offering 5V, 6V or 7.2V at 10A sustained output, with 18A instantaneous output. The ESC has a stated peak current of 130A. Its 120A continuous-current specification carries a closed-incubator test qualification of 2min6s, a material duration condition when assessing the controller for a propulsion installation.
