INSTALLING THE PROPELLERS
Each arm of the H520 has a letter A or letter B labeled on it. “A” arms have black center buttons; “B” arms
have white center buttons.
Each propeller has an A or B label etched into the blade. “A” propellers cannot be attached to “B” motors,
nor can “B” motors be mounted to an “A” motor.
Match the A propellers with the A arms (black center button) and the B propellers with the B arms (white
center button). Place the prop on the motor, lightly press down and while holding the motor and turn the
prop a quarter turn. A click will be heard and the center button will slightly pop up. Hold the motor and test
propeller security to assure a locked propeller.
