Safety Instructions
OPERATING YOUR MODEL SAFELY
Operate the helicopter in spacious areas with no people nearby.
! Warning: Do NOT operate the helicopter in the following 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 dis-
connect the batteries. Investigate the reason and 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 ying the helicopter, ensure that all screws are tightened. A single loose screw may cause a major acci-
dent.
Replace all broken or defective parts with new ones, as damaged parts lead to crashes.
Never approach a spinning rotor. Keep at least 10 meters/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 MODEL, 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 assembly and
for pre-ight adjustments. Note that a badly assembled or insufciently adjusted helicopter is a safety hazard!
In the beginning, novice R/C helicopter pilots should always be assisted by an experienced pilot and never y
alone!
Throttle channel should be in motor OFF position while powering up.
When switching the R/C system ON or OFF, always proceed in the following order:
When switching ON:
Position the throttle control stick (on transmitter) to a position where the LOGO 10 motor does not operate.
Turn on the transmitter.
Turn on the receiver.
Connect the motor battery.
Operate your model.
When switching OFF:
Turn off the motor (move throttle control to a position where motor does not operate).
Wait until the rotor head has stopped spinning.
Disconnect the motor battery.
Turn off receiver.
Turn off transmitter.

3 Motor Installation
3.1 Motor Attachment
Bag 1 • Bag 12
When installing the motor, tighten
the socket head cap screws only
slightly, making sure that the motor
can still be moved on the motor
plate.
Do not tighten the set screw fully until
the nal position of the pinion on the
motor shaft is determined. This is
done after installing the main gear.
There are two options for attaching
the pinion:
1. For securing the pinion, you may
atten the motor shaft where the set
screw meets the motor shaft - without
making a at surface on the motor
shaft.
2. Alternatively, you may screw the
set screw directly onto the motor
shaft. For this it is required that the
set screw has an appropriate rim for
engaging the motorshaft (all Mikado
pinions have this rim). Note, however,
that after attaching the set screw
once, the rim becomes blunt and may
not be used again.

4 Main Gear
After having attached the freeway
hub of the main gear to the rotor
shaft, pull the rotor shaft slightly
upward and simultaneously push
the main shaft collar down onto ball
bearing. Next tighten the set screws.
The rotor shaft should turn easily and
it should not have any axial play.
4.2 Adjusting Gear Backlash
The gear backlash must be adju-
sted (see drawings). Excess back-
lash can cause premature wear of
the main gear and will lead to shorter
ight times.
too much backlash correct backlash too little backlash
