8 ChaNgINg The propellerS
If the rotor blades of the multicopter are damaged, they must be replaced.
Proceed as follows:
8A Prior to installation, make sure that you do not mix up the propellers.
The multicopter has 3 different propellers, which differ in colour and direction of
rotation. If the propellers are mixed up, the multicopter will not fly. The two blue
propellers are in front. Please also make sure that the propellers are correctly fit
on the motor shaft. The upper side is bent slightly downwards. A small „A" or „B"
can be found on the underside of the propellers. If the propellers are mixed up,
the copter will not fly.
8B Now carefully pull the propeller off the shaft of the motor.
8C Carefully fit the new propeller on the shaft and carefully screw the securing screw
on again in a clockwise motion.
