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 injur y 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 fix 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 obser ve the following:
Before flying 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 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 necessar y 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-flight adjustments. Note that a badly assembled or insufficiently adjusted helicopter is a safety hazard!
In the beginning, novice R/C helicopter pilots should always be assisted by an experienced pilot and never fly
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 Adaptor Plate
Bag 1
2x M3x8 #1915
Some electric motors (e.g. Kontronik, Plettenberg, Speed 700 Neodyme motors) are constructed such
that they cannot be moved along the
motor plate. If you are using one of
these motors, please use the motor
adaptor plate #2499. The plate is not
needed for Hacker motors.
Please check from the Mikado
website which pinion works best with
the motorset you have (on
www.mikado-heli.de go to LOGO 10
and click “Motorization”). When a
wrong pinion is chosen, the performance of your electric helicopter will
deteriorate and the motor or speed
controller can be damaged.
Do not tighten the set screw fully until
the final 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
flatten the motor shaft where the set
screw meets the motor shaft - without
making a flat 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, howev er,
that after attaching the set screw
once, the rim becomes blunt and may
not be used again.

Bag 2
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.
too much backlash correct backlash too little backlash
4.2 Adjusting Gear Backlash
The gear backlash must be adjusted (see drawings). Excess backlash can cause premature wear of the
main gear and will lead to shorter flight
times.

5x10x4 bearings can also be mounted 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.

Important: Check belt tension
prior to every flight. Incorrect belt
tension can cause disturbances
for your model R/C system.
Incorrect 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 fixed with the M3x18
socket head cap screw for tightening
the tail boom holder to the tail boom.
The belt should be tight. When pressing with your fingers, both sides of
the belt should not come in contact
with each other.

8 Preparation for Servo Installation
8.1 120° CCPM
The swashplate in the LOGO 10 is
designed to be operated by three servos. The tr ansmitter provides for electronic mixing. You may choose from
two different methods for mixing the
swashplate: 90° CCPM and 120°
CCPM. Mikado recommends 120°
CCPM. Installation and programming
of 120° CCPM is explained and illustrated below.
120°
8.2 90° CCPM
90° swashplate mixing differs in a
few details from 120° mixing (programming of transmitter, installation
of swashplate servos and elevator
servo movement.) Installation and
programming of 90° CCPM will not
be explained below.

flying styles, different pitch ranges
must be used. For normal flight with
some aerobatics, choose standard
settings and connect the push rod at

9 Servo Installation
9.1 Tail Rotor Servo
With LOGO 10 side-frames you
can use two different sizes of tail rotor servos. A larger standard-size tail
rotor servo can be mounted to the left
side-frame, a smaller mini servo is
mounted to right side-frame.
For determining the appropriate
position for mounting the tail rotor
servo, place the servo against the
chassis and mark the holes for attachment with a pen or needle. Then
drill where you have made the markings. The ball links are attached
more easily when the text on them
are pointed awa y from the helicopter.

When microservos
are used, the linikages
should be aligned as
close as possible to vertical.
When using larger servos the linkages should
be aligned as close as
possible to vertical or
have the same angle.

120° Swashplate Mixing (120° CCPM)
The LOGO 10 swashplate is designed to be controlled via electronic CCPM. Thus the corect control
inputs of the three swashplate servos are automatically mixed by the R/C transmitter. If you have never
programmed 120° CCPM before, please read this introductory text carefully.
Collective (Pitch)
Pitch function is used to control the lift or sink of the helicopter. When pitch input is given, all three s washplate servos travel together in the same direction and the same amount. As a result the swash-plate
moves up or down on an even level.
Minimum Pitch Maximum Pitch
Aileron (Roll)
Aileron (roll) is used to control the helicopter’s movements around its longitudinal axis. When aileron
(roll) input is given, the two roll servos (in the front of the swashplate) travel in opposite directions. As a
result the swash-plate tilts to the right or to the left.
Manual

Elevator (Tilt)
For tilting the helicopter , use the ele v ator function. F or tilting f orward, the two aileron servos mov e do wnward and the backward elevator servo moves upward. The elevator servo moves twice as much as the
two aileron servos.
Elevator forward Elevator forward (view from side)
Programming 120° CCPM
As the programming procedure varies with different types of R/C systems, it is necessary for you to refer
to the instruction manual of your R/C system. Here are only a few general guidelines which apply to most
systems.
Servo Centering with Sub-Trim Function
As indicated in the above sections on mounting the servos, it is important that the servo arms are exactly
centered. You should use the servo sub-trim function of your R/C system for this purpose.
Activating 120° CCPM
Likely, the 120° CCPM function is initially disabled in your R/C transmitter software and needs to be
separately activated. Please refer to your R/C system manual, where you will also find information on
which channels should be used for the elev ator servo and the two roll servos. It is important that you stick
with the requirements stated in the manual. Otherwise the 120° CCPM will not function properly.
Your R/C may support various different CCPM mixings. F or Logo 10 choose the 120° mixing with two roll
servos in the front and one elevator servo in the back.
Use the relevant menus for setting the mixing proportions for roll, elevator and pitch functions. Begin by
setting the mix values to 50% each. Higher mix v alues give higher servo tra v el f or that function This can
have the unwanted result that the swashplate reaches its mechanical limits and causes damage to the
servos or rods or to the swashplate.
If necessary , you ma y use the CCPM menu to re verse the direction of the function. This is necessary, for
example, if the swashplate tilts to the wrong side or the pitch function is inverted.
The menu for reversing servo functions can be used for reversing the movements of individual servo
arms, but not for reversing the entire control function and of all the involved servos.
Manual
LOGO 10

14 RC Programming
Servo Travel
It may be the case that all swash-plate servos do not travel the same distance at maximum deflection.
Even small differences between the 3 servos can prevent the swash-plate from being level during
collective pitch inputs and cause the heli to drift.
In order to correct such servo travel differences, you must increase or decrease the servo travel setting
accordingly. Use the menu ATV for adjusting the end points, if necessary . Do not get this menu mixed up
with Dual/Rate. (Dual/Rate menu allows using multiple servo travel ranges and toggling between them
during flight.)
Example:
If during maximum pitch the elevator servo travel is slightly smaller than travel of the two aileron servos,
then the swash-plate will be tilted backwards, causing the heli also to drift backwards. In this case you
should increase the travel of the elevator servo.
Increase servo travel of
elevator servo on one side
All servos travel the same
distance at maximum deflection
Setting Pitch Values
Please choose from two different pitch settings, depending on your flying style. The two settings are
illustrated below. The standard range is for beginners and for pilots who will do some aerobatic flight
without extended periods of inverted flight.
The final pitch values must be tested during test flying. Once set, the values will work with the rotor
blades you used. In case you change over to a different set of rotor blades, the pitch values will have to
be adjusted to the properties (size, profile etc.) of the new set.

Aileron and Elevator Travel
The travel range of the aileron and elevator servos are limited by the swash-plate’s mechanical limits.
Please take care that the sw ash-plate does not hit the maximum of its travel. This can ha ve the unwanted
result that the swashplate reaches its mechanical limits and causes damage to the servos or rods to the
swash-plate itself.
If you desire more agility for your helicopter, use lighter flybar paddles.
Tail rotor settings
When the servo arm of the tail rotor servo is in the center, the tail rotor le ver and the servo arm should be
perpendicular with respect to each other. The tail rotor pitch lever should never reach its mechanical
limits.
In case the servo travel is too large, you have the following options for correcting this:
1. Move the ball end of the tail rotor servo closer to the center of the servo arm.
2. Reduce the servo travel in your R/C system using ATV.
3. Reduce the servo travel in your gyro (not all gyros have this option).
In case the servo travel is too small, you have the following options for correcting this:
1. Mov e the ball end of the tail rotor servo further awa y from the center of the servo arm.
2. Increase the servo travel in your R/C system using ATV.
3. Increase the servo travel in your gyro (not all gyros have this option).
Ensure that the tail rotor servo turns in the correct direction. If necessary , re v erse the direction of the tail
rotor servo function in your R/C system.
Adjust the tail rotor linkage in
length such that the tail rotor servo
arm and the tail rotor lever are at
90 with respect to each other.
All parts serving the tail rotor
movements must move smoothly.
When there is too much resistance, the tail rotor will not react
to subtle input and the gyro’s
maximum sensitivity cannot be
fully exploited.
Revo-Mix/Gyro
It is necessary to compensate for the torque created by the motor during flight (but not during autorotation).
This compensation is done by adjusting the tail rotor pitch. There are two options for achieving this:
1. Using normal gyro mode
Please refer to your R/C system manual for activating the revolution mixing function and for setting all
parameters correctly. Final settings should be trimmed during test flights.
Manual
LOGO 10
Page 53 ©Mikado Modellhubschrauber
14 RC Programming
2. Using a gyro in Heading-Hold mode
The Heading-Hold gyro mode compensates automatically the deviation caused by the motor torque.
Therefore, if Heading-Hold mode is used, revo-mix should not be programmed additionally.
Important: Check to ensure that the tail rotor assembly mov es smoothly and without play. Otherwise the
gyro and servo will not compensate the torque properly .
Rotor Head RPM control
LOGO 10 is designed to be flown with constant rotor head speed. Irrespective of flight attitude (ascending,
descending, hovering), rotor speed should be kept roughly constant. There are two different methods f or
obtaining constant rotor speed:
Rotor speed control with speed controller
All speed controllers can be used in this mode. With speed controller it is necessary to program a throttle
curve (see manual). Programming of throttle curve requires that you associate a given throttle value with
a particular pitch value. In this way, the rotor speed is held almost constant with all pitch values.
Throttle curve programming depends on the type and quality of the R/C system. Simpler , ine xpensiv e R/
C systems designed for model helicopters usually have a 3-point throttle curve. High-end R/C systems
typically have throttle curves with more configurable points (up to 9). Fine tuning of throttle curves will be
necessary during test flights.

Note that wrong throttle curve settings reduce performance and can lead to overheating of the motor and

Rotor speed control with governor (RPM regulation mode)
A speed governor keeps the rotor speed constant, independent of flight condition. Thus, no programming
of throttle curves is necessary. The easiest way of toggling between two rotor speeds is by way of a
switch. Usually, only speed controllers for brushless motors have this feature.

15.1 Trimming and Taping
Tip: When cutting, always leave
generous edges at first. Cut to final
size after you have fitted parts.
On both of the white halves, a marking indicates where the window belongs. With a scissors, trim away the
excess material at the two white hal-
ves of the canopy along the
insides of these markings.
Unlike in the picture, please do not
cut sharp edges at the top and back
ends of the canopy. The rounded
edges must be retained for stability.
After taping the two halves together
and fitting the window, you may trim
away any excess edges.
In general, we recommend to use
transparent scotch tape on the insides of the three canopy parts for connecting them. Taping provides sufficient stability and the procedure is
easier and less time-consuming than
gluing (for instance). Corrections, if
necessary, are no problem either.

The LOGO 10 canopy is attached
to the main frame in three places. The
lower part of the canopy is placed
between the front landing bow and
the main frame. For this, you need to
make to cut-outs as shown in the picture. The back part of the canopy is
attached at the canopy bolts of the
main frame using two rubber
grommets.
The final fitting of the canopy must
be tested when the helicopter is fully
equipped (with battery, servos and
linkages). Ensure that the servo
arms and linkages do not have any
contact with the canopy. In the front
area, the battery may and should
have contact with the canopy providing additional support. When more
than 12 cells are used, extra room in
the nose of the canopy by padding
the battery , thereby lifting it slightly.

16 Rotor Blades
Balancing of Rotor Blades (Center of Gravity)
Place each rotor blade over an
edge as shown in picture (1). Adjust
the blades so that they are in equilibrium. If the center of gravity is not in
the same place in each blade, this
needs to be corrected using tape.
Apply as much tape as necessary
until both blades show their center of
gravity in the same place.
Static balancing
Screw the rotor blades together as
shown in picture (2). The rotor blades are properly balanced when they
are suspended exactly horizontally.
If one of the rotorblades is not exactly horizontal, the blades are not in
equilibrium.
This is corrected by applying tape
to lighter blade.
When mounting the rotor blades to
the blade holders, note the proper direction (clockwise rotation). Tighten
the cap screws holding the rotor blades, so that the blades cannot move
easily in the blade holders.

17 Final Pre-Flight Check
17.1 Direction of Main and Tail Rotation
Prior to the first flight double-check
the direction of rotation of the main
rotor head and the tail rotor.
17.2 Blade Tracking Adjustment
OKFalse
Prior to the first flight the tracking
of the rotor blades needs to be adjusted. If the tracking is not adjusted
properly, this can cause vibrations
and lead to instability of the helicopter.
Apply colored tape to the tip of one
of the rotor blades. Apply tape of a
different color to the tip of the other
rotor blade. When you are ready for
your first flight, increase the rotor
speed to just before lift-off. From a
safe distance, check the rotor disk
at eye-lev el. V e ry likely , one rotor blade will move below the other.
Make a note of the color of the lowmoving blade. Then turn off the motor and wait until the rotor head has
come to a halt. Lengthen the linkage
(1) of the rotor blade which was moving low by unscrewing the ball links
somewhat. Repeat the checking procedure until both rotor blades move
on the same level.

18.1 Pitch/Throttle
You may want to program a different stick mode than the one shown.
Please check which stick mode is
used by other local pilots. Use the
same one, so fellow pilots can assist
you on the field.
Important: Flying a model helicopter requires many hours of training.
During your first attempts, while familiarizing yourself with the different
control movements, keep the helicopter low above the ground (just a
few centimeters/a couple of inches.)
