11. Maintenance and Care
Clean the exterior of the model and the remote control only with a soft, dry cloth or brush. Never use abrasive cleaning
agents or chemical solutions as these could damage the surfaces of the casings.
a) Replacing the Rotor Blades
If the turning rotors hit an obstacle, parts of the rotor
blades may break off. In this case, replace the defective
rotor blades with genuine spare parts.
Attention!
Never fly the model helicopter with
defective rotor blades because the resulting
vibrations may cause greater damage to
the model.
Observe the rotational direction of the rotor when
replacing the main rotor blades.
The rotor blades of the top rotor (1) turn clockwise and
the rotor blades of the lower rotor (2) turn counter-
clockwise.
Do not overtighten the fastening screws of the rotor
blade retainers (also see figure 6).
b) Replacing the Tail Propeller
If required, the tail propeller (1) can simply be pulled
off of the motor shaft upwards manually.
When putting on the replacement propeller, ensure that
the propeller is not skewed which would bend the motor
shaft.
Regularly check all screw connections of your helicopter
for tight fit. All moving parts have to be easily movable
but there should not be a clearance in the bearing.
