ill try to give u as much info as i know. that black board is your speed controll. the black wire coming off the motor needs to soldered onto the speed controll? where I dont know .cant see it. The red wire coming off of the clear battery plug also needs to be soldered onto the speed control. The red wire (by itself) coming off of the speed control plugs onto the red wire coming off of the motor. Lastly- I hope u have the linkage that connects the speed controll to the servo. the linkage is basically a steele bar with a ball hitch at the end. If you dont have more parts for the speed controll i'd suggest buying a electronic speed controll.
