b) Assembly of the Propellers
The quadrocopter comes with 1 pair of left-turning propellers (1) and 1 pair of right-turning propellers (2) each.
Important:
Observe the rotating direction of the propellers at in-
stallation. The propellers at the front left and the rear
right turn clockwise when viewed from above; the
propellers on the front right and rear left turn counter-
clockwise (see rotating direction arrows in gure 2).
In addition to the motors, circular arrows are placed on the top of
the housing to indicate the rotating direction precisely.
The arrow in the upper half of the picture shows the ight direc-
tion of the model forwards.
Attention!
The propellers have glued-in attachment nuts (see gure 2, item 3), which tighten when the quadrocopter is
in operation.
To attach the propellers, place the respective propellers on the threads of the motor shafts and manually turn
the propellers contrary to the regular operating rotating direction. Hold the bell of the brushless motor with
the other hand.
Wear protective gloves when installing the propellers to avoid injury from the thin and sharp-edged propel-
lers.
Do not over-tighten the propellers and do not use any threadlocker varnish or glue to secure the propel-
lers.
If a propeller is damaged (cracks or small pieces broken out), replace the defective propeller without delay.
Do not continue to use defective propellers.
Stay away from turning propellers to avoid accidental injury.
If the propellers must be replaced, use only the spare propellers provided by the manufacturer.
