HOW TO CHANGE THE PROPELLERS
WARNING: Any changes to accessories, including propellers, must be carried out by an adult.
The propellers should be positioned in a specific way, as on this positioning depends how they expel
the airflow and, therefore, whether the flight is correct and even whether it takes off or not.
If after a small impact due to which you had to change the propellers, either because they have come
loose or because they broke, you notice some of the following symptoms, it means they have been
placed incorrectly.
• The Spaceball doesn't take off, not even after you apply power to it.
• It raises the nose or the tail, but it doesn't take off. The spaceball moves forwards or backwards but
does not take off.
Pay special attention to the following illustration.
There can't be three identical propellers. There are 2 different types of propellers, and they must be
placed in a cross pattern (as shown in the illustration above).
A.
The left front and right rear must be the same. Model A
B.
The front right and rear left should be the same. Model B.
Pay attention to the torsion of the propeller of each model presented. The arrows indicate the direction
of the blade drop.
