Installing the motors

Step 14: To prepare the motors, mate the motor shaft to the top of the propeller and then take the three smallest screws and secure the propeller shaft to the top of the motor.

Step 15: To mount the X piece to the bottom of the motor using the remaining four screws, you must first find the configuration that allows all the holes to line up by rotating the X piece. Secure with the four screws and tighten down. Gently secure the flange and the nut for safekeeping until you put on the propellers. Repeat until all four motors are assembled.

Step 16: To mount each motor, line up the holes of the mount with the outer holes on the X piece so that the wires go back along the arm and thread a small zip tie from top to bottom and then loosely connect the ziptie. Do this on all four holes so that the motor is sitting on the mount with all four zip ties loosely connected and then tighten each ziptie a little at a time before moving onto the next ziptie in order to get the motor centered and flush with the mount. You are done with the motor connection when the motor is tightly bound to the mount. Trim all the zipties to be flush with the ziptie connection.
