5. Maintenance
Helicopters, whether large or small, place considerable demands on maintenance. Whenever
you notice vibration in your model, take immediate steps to reduce or eliminate it. Rotating
parts, important screwed joints, control linkages and linkage junctions should be checked before
every flight. If repairs become necessary, be sure to use original replacement parts exclusively.
Never attempt to repair damaged rotor blades; replace them with new ones.
Since the model is supplied factory-assembled, you will not have acquired any particular know-
ledge about its construction.
The following section therefore describes the procedure for assembling the model from its com-
ponent parts; this may be important for subsequent maintenance and repair work.
5.1 Assembling the model from components
The main rotor shaft is supported in two ballraces, and the first step is to fit them in the chassis
side frames. Fix the two chassis frames together permanently using the appropriate self-tapping
screws.
Install the battery holder 4441.326 and screw it to the chassis. Attach the tail boom holder at the
same time: fit the top and bottom sections for the toothed-belt version; the shaft-drive version
only requires the top section.
Press the freewheel bearing into the main gear 4441.23 (check the correct direction!), then slide
the freewheel sleeve into place as shown. Install this assembly in the chassis.
