To answer your questian more direct. you have 4 bare wires comming from the silver box/ electronic speed control/ESC (the one I hate some much) two of thoes go to the battery, probably the two with alligator clips, I dont know if there is a problem in reversing them or not, so just make sure to hook the red to pos and the black to neg. the other two green wires go to the motor and if they are reversed the motor will only run opposit so this is just trial and error. Find the transmitter, put in good batteries, and go.
