OPERATING YOUR MODEL SAFELY
Operate the helicopter in spacious areas with no
people nearby.
!Warning: Do NOT operate the helicopter in the fol-
lowing places and situations (or else you risk severe
accidents):
• in places where children gather or people pass
through
• in residential areas and parks
• indoors and in limited space
• in windy weather or when there is any rain, snow,
fog or other precipitation
If you do not observe these instructions you may be
held reliable for personal injury or property damage!
Always check the R/C system prior to operating your
helicopter. When the R/C system batteries get weaker,
the operational range of the R/C system decreases.
Note that you may lose control of your model when
operating it under such conditions.
Keep in mind that other people around you might also
be operating a R/C model.
Never use a frequency which someone else is using
at the same time. Radio signals will be mixed and you
will lose control of your model.
If the model shows irregular behavior, bring the model
to a halt immediately. Turn off all power switches and
disconnect the batteries. Investigate the reason and
fi x the problem. Do not operate the model again as
long as the problem is not solved, as this may lead to
further trouble and unforeseen accidents.
! Warning: In order to prevent accidents and personal
injury, be sure to observe the following:
Before fl ying the helicopter, ensure that all screws are
tightened. A single loose screw may cause a major
accident.
Replace all broken or defective parts with new ones,
as damaged parts lead to crashes.
Never approach a spinning rotor. Keep at least 10 me-
ters/yards away from a spinning rotor blades.
Do not touch the motor immediately after use. It may
be hot enough to cause burns.
Perform all necessary maintenance.
PRIOR TO ADJUSTING AND OPERATING YOUR MO-
DEL, OBSERVE THE FOLLOWING
!Warning: Operate the helicopter only outdoors and
out of people’s reach as the main rotor operates at
high rpm!
! Warning: While adjusting, stand at least 10 meters/
yards away from the helicopter!
Novice R/C helicopter pilots should always seek advice
from experienced pilots to obtain hints with assem-
bly and for pre-fl ight adjustments. Note that a badly
assembled or insuffi ciently adjusted helicopter is a
safety hazard!
In the beginning, novice R/C helicopter pilots should
always be assisted by an experienced pilot and never
fl y alone!
