How do I connect my esc to my frsky x4r reciever


Eternal Student
The 2 pads inside the power supply wires are for the ESC signal and signal ground. If they aren't labeled, you can check with a multimeter, the 2 grounds on that side will be common. It doesn't appear to have a BEC, so you'll have to power the receiver from somewhere else.
