c) Assembly of the rotors
The rotating direction of the rotors can be seen in figure 4 (bird’s eye view). The position of the red direction indicator
on the landing leg and the arrow on the radial arm is to be used as the indication for the direction of the model and is
deemed to be „in front“.
Attention!
As the motors are pre-assembled, the
rotating direction of the rotors on the
basis of the flight direction should be
carefully observed (figure 4)!
The rotors in the centre line (1) turn
clockwise (right rotating) and must be
marked with the inscription „right“.
The rotors on the cross axis (2) turn
anticlockwise (left rotating) and must be
marked with the inscription „left“.
Attention!
If the rotors are not installed as described, the programmed rotating directions will no longer be in line with
the rotating directions of the rotors. The QuadroCopter is therefore no longer able to fly and can no longer
be operated!
Rotors and motor shafts are provided with a hexa-
gonal bolt (3).
Place the rotors (1) on the motor shafts (3) so that
they lock into place in the hexagonal bolt.
Now insert one of the provided spring washers (4)
at a time between the rotor and rotor tip (5), as
otherwise the rotors may become loose during
flight.
Screw the rotor tops to the motor shafts manually.
Attention!
Tightening the screws too much can damage the motors. The shafts may tear or be pulled from the
bearings. The motors operate sluggishly, which may have a negative effect on the flight characteristics.
Therefore, please verify that all of the rotors can turn easily after tightening the rotors. The snap ring shown
in figure 5, item 6, on the underside of the motors must be able to move and must not jam.
Please ensure before each operation that the rotors are firmly screwed in place on the motors. It is
recommended that you are careful when handling work tools.
