Based on XPS Pro V2, this ESC has been upgraded to 100A ampere spec and higher graded FET’s to lower the hardware internal resistance with more power output and lowers the speed controller working temperature. It supports Ch3/Ch4 Aux Input signal to control different item function values (this parameter can be set from LCD card directly). The BEC is 6V/7.4V selectable/max ~35 (this parameter can be set from LCD card directly). The product comes with 12AWG high-density copper super soft wire, which provides better stability and reliability, same as supplied on the RADON VS. It has been upgraded to Radon Pro V4 speed control firmware for default factory setup. The product is compatible with Radon V4 series speed control firmware.
