11. Maintenance and cleaning
Clean the exterior of the model and the remote control with a soft, dry cloth or brush. Never use abrasive cleaning
agents or chemical solutions, as these may damage the surface of the case.
Replacing the rotor blades
The rotor blades may be damaged if they hit an object when they are rotating. If this occurs, the defective rotor blades
must be replaced.
Warning!
Do not y the helicopter if the rotor blades are damaged, as this may result in vibrations that cause further
damage to the model.
Ensure that the main rotor blades are inserted in the correct orientation.
The rotor blades of the upper rotor (1) rotate clockwise as
viewed from above and the rotor blades of the lower rotor
(2) rotate counter-clockwise.
Do not overtighten the screws on the rotor blade holders.
(see also Fig. 6)
