I am trying to build the X500 drone and have currently finished up soldering the connections between the PM07 and the 4x BL Heli ESC 20A’s. The soldering was successful, however, there are two other intertwined wires coming from the ESC’s- which are the signal and ground wires (yellow and black). I am wondering how do I connect these to the PM07? Which exact pins do I use for the connection? And after I finish up the wiring process, can I just press the calibrate button on QGroundControl to finish up setting the ESC’s up, or is there more to do?
