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 insuf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 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

Bag 5 • Bag 10 • Bag 11

Should you have difculty mounting

the 2x10 mm pin, carefully tap it with

a rubber hammer, or use a vice. The

5x10x4 bearings can also be moun-

ted on the rotor shaft using a vice and

tapping the shaft softly with a rubber

hammer. If the tail rotor shaft shows

axial play after closing the two halves

of the tail rotor case, use one or two

of the 5x10x0.1 washers which are

included in the bag.

It is important that the tail pitch pla-

te #3030 is aligned properly on the

control sleeve #2455. In the case of

misalignment, the control sleeve may

become deformed.

The mounted tail pitch plate should

be able to move on the tail rotor shaft

with little resistance.

Bag 6 • Bag 10 • Bag 12

Important: Check belt tension

prior to every ight. Incorrect belt

tension can cause disturbances

for your model R/C system. In-

correct belt tension can lead to a

situation where you lose control of

the tail rotor of your helicopter.

For tightening the belt pull the tail

boom holder toward the front. Belt

tension is xed with the M3x18 sok-

ket head cap screw for tightening the

tail boom holder to the tail boom. The

belt should be tight. When pressing

with your ngers, both sides of the

belt should not come in contact with

each other.

insert a strip of paper between the

main gear and the drive pulley, then

press the drive pulley against the

main gear.
