Maintenance and Care
Clean the exterior of the model and the remote control only with a soft, dry cloth or brush. Never use aggressive
cleansing agents or chemical solvents, since this might damage the surfaces.
All moving parts have to be easily movable but there should not be a clearance in the bearing. The motor shafts with
the rotor shaft must be aligned perfectly straight and must not be eccentric.
Check the mechanical parts of the model throughout at regular intervals. All screwed connections should be tight and
should not loosen up due to vibrations of the helicopter.
Make sure that the grub screws in the top set collar (1) and
the bottom set collar (2) of the main rotor shaft have a tight
fit.
Important!
If you have to replace damaged or worn parts, use original replacement parts only.
The spare parts list is located on our website www.conrad.com in the download section to the respective

You can also order the replacement parts list by phone. For contact information, please refer to chapter
