Hello, so I just got four of these ESC's to run 3508-268 elite multistar motors. One of them will not calibrate automatically/manually or even connect to the BLHeli software program to view or reflash. It just continues to beep away waiting for input calibration, but the other 3 ESC's will calibrate. I've even bypassed the Flt control board and connected the esc direct to the throttle channel of my rx to no avail. I'm using a JR X9303. If I try swapping the motor signal output leads from the FC board, there is not change to the problem ESC, yet that output signal lead from the FC board works just fine on the other ESC's. I'm thinking about getting the Atmel Atmega Socket Firmware Flashing Tool & USBasp AVR Programming Device for ATMEL proccessors to rebootload SimonK onto the chip, does anyone know if this will work even when the BLHeli software won't recognize it?
