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!

Installation of the Motor Pinion
Screw the motor pinion onto the motor shaft, making sure that it
can still be moved. Now mount the motor on the motor plate and
move the pinion so it is aligned well with the main gear. As visual
help for aligning the pinion you may use the small ridge which
separates the two parts of the pinion. When the pinion is aligned
correctly it will easily engage with the main gear. If the pinion does
not engage with the main gear, it is not correctly aligned. After the
pinion is correctly aligned, take the motor out of the mainframe
and tighten the set screw.
Gear Backlash
Move the motor with the pinion until it is limited by the gear. Tighten
one of the M4x32 screws slightly. You must still be able to swivel
the motor around its own axis. In this way you can easily deter-
mine the correct distance between the main gear and the pinion.
There should be no (!) gear backlash. At the same time, the motor
should not (!) exert any pressure onto the running surface of the
main gear. After you have determined the correct distance, tighten
the second M4x32 screw.
Bag 2
Please mount the motor, motor plate, pinion
and counterbearing as illustrated in the above
picture. . Make sure that the M3 set screw
sits on the flattened area of the motor shaft.
For mounting the new motor counterbearing with ro-
torshaft suport, please follow these steps: First, mount the
main gear, the rotor shaft assembly and all shims. Secure
assembly with the 10 mm c-clip (Picture 2). The main gear
will have 0.5 mm axial play. This is normal and will facili-
tate the mounting and positioning of the pinion later on.
Now mount the motor and the counterbearing. Once the
motor position is set (please ensure correct gear back-
lash!), please screw the rotorshaft support onto the coun-
terbearing, using the three M3x6 screws.
