In this page we will see how the propeller securely connects to the motor. Use the video above for a visual reference.
First, place the propeller on to the bolt with the lettering on the propeller facing the motor.
After the propeller is on the bolt facing the correct direction, place the washer on the bolt. Make sure the side of the washer with the larger face is against the propeller. Then, tighten the nut to bolt very tightly securing the propeller and washer. If this bolt is too loose the propeller may fall off during a flight.
When all of these steps are done the propeller will be properly secured to the motor.
After the propeller is installed it is advised to proceed with caution when working near the plane.
After verifying that the Propeller is secure proceed on to Center of Gravity.
