I have some of the old ESC's shipped by 3dRobotics. It does not have the SimonK firmware. I was wondering if I can flash it with the SiminK firmware. If yes then what setting do we use to build the firmware. By “setting”, I mean what is this type of ESC. ( Eg. bs40a_esc, thanksdlu40a_esc, bs_nfet_esc, etc.).
