Yes, simply plugged in the Li-Po and half way through the ESC start up chime I heard a pop and a fairly large plume of smoke.
My understanding is that using the provided cable (note gnd and positive cables removed):
One can output the ESC signal cables from the 4in1 to the molex on the FC as shown:
The idea was to create a tidier build avoiding having to solder signal wires from the 4 in 1 to their corresponding pads on the FC.
Is this wrong?
ESC's were in OneShot 125 and I hadn't got round to BLHeli Suite (hoping to use Damped Light)
