I am wondering if you guys can help me to connect one 4in1 ESC to the Flight Controller(Pixracer1.4). I am concern if I did connect it right because reading through the instruction I found this: Signal and GND are mandatory.
Since my 4in1 ESC has 4 signals, and only 1 ground, I can not really connect the ground into every single channel. I attached some images to help explain.
In another forum, a friend suggest to chain one ground to all/any ground connection although Im not sure.
I am also wondering if it is possible to test the motor direction and see if they are spinning to the right direction and if the communication is working ok though the flight controller and the 4in1 ESC.
I look forward to hear from you guys.
