9 CHANGING THE PROPELLERS
If the rotor blades on the model are damaged, they must be replaced.
To do so, proceed as follows:
9A Unscrew the screw of the rotor blade anti-clockwise. Hold the faulty rotor blade with
two fingers and pull it off carefully to the top.
9B Place the new rotor blade on the shaft and screw in the fixing screw carefully in
clockwise direction. Caution: Do not tighten the screw too tightly, as this could
damage the thread.
9C When mounting the rotor blade, please note that there are right-turning (A) and
left-turning (B) rotor blades.
