Step 30: Attach Propellers

STOP!! Propeller blades can cut skin. Do not install propellers until you are ready to fly in a properly prepared indoor OR outdoor flying area. Never install propeller blades on a quadcopter in a classroom or a bench testing area.  Never connect the flight controller to a computer if the propeller blades are installed.

Attaching the Propellers in the wrong positions is the #1 most common mistake, so follow the directions below carefully!

Tools Needed:

  • 5/16" Wrench, 5/16" Socket, or Adjustable Wrench
  • Flat-nose Pliers

Parts Needed:

  • ELEV-8 v3 Assembly, prepared in Step 29
  • 4 – Propeller Adapter Nuts (one included with each motor)
  • 4 – Propeller Adapter Washers (one included with each motor)
  • 2 – 11x4.5 CCW (L) Propeller (#721-80040)
  • 2 – 11x4.5 CW (R) Propeller (#721-80041)
  • 4 – Propeller Spacer Ring (included with each propeller)

WARNING: Do not install the propellers until you have gone through every step of the Assembly Guide.

Instructions:

  1. Remove the spacer rings from the propeller bags and place the one indicated in the figure below over each propeller adapter shaft.

  1. Attach a CW (R) propeller to motor #1. Place the propeller over the adapter shaft so that the small writing near the center of the propeller is upright, as shown in the image below (the sharper edges of the propeller should be on the bottom).
  2. Place a washer over the propeller so that the flat side is down.
  3. Thread a nut onto the adapter and tighten until it makes contact with the washer and propeller, and the resistance increases; then tighten another 1/4 turn.

  1. Using the same procedure, attach a CW (R) propeller to motor #3. Attach a CCW (L) propeller to motors #2 and #4.

 

Now it's time to learn to fly!

Congratulations on completing the assembly of your ELEV-8 v3 Quadcopter! We know you are probably anxious to fly it, so please head over to the How to Fly a Multirotor sUAV tutorial, where you will learn how to fly your ELEV-8 v3.  PLEASE DO NOT attempt to fly your ELEV-8 v3 until you have read through both the How to Fly a Multirotor sUAV and UAV Safety, Laws, and Good Citizenship tutorials, as you could put yourself and others needlessly at risk. (For example, the Flying Guide contains important information on how to identify and switch between flight modes).
