so I can connect it without a flight controller to my receiver . right?A 4-1 has a wire set that has signal and power wires that go to a flight controller. Each motor‘s ESC on the 4-1 has a separate signal wire, then there will also be a hot wire and ground wire. There may also be a BEC hot wire. Unless you can read a schematic and test voltages you probably should not attempt this or you risk burning up your ESC or your receiver.
