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 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 observe 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
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.com 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.
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.
too much backlash correct backlash too little backlash

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 Canopy
8.1 Mounting
Bag 1
The canopy does not yet have any holes for attaching it to the helicop­ter. In order to fit the canop y properly to your model, please proceed as fol­lows: First, use rod no. 743 for mar­king where the holes will be cut out. Push the rod through the mainframe, as shown in the picture. Then positi­on the canopy exactly like you want it to be attached to your helicopter. The lower end of the canopy will al­most touch the tail boom. Close the canopy with tape, letting the two hal­ves overlap slightly.
Now apply light pressure to the canopy in the area of the two ends of the rod. In this way you will obtain round marks just where you need to drill the holes for attaching the cano­py. Drill two holes with 8mm diame­ter each. After drilling, place a cano­py fixing ring no. 2503 into each hole.

11 .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 away from the helicopter .

Before mounting the rotor head, ple­ase choose from one of the following two types of head adjustment, as they will influence the agility and sta­bility of the helicopter.
1) very agile, very direct cyclic re-
sponse, suitable for 3D-style flying.
2) very stable performance, calm cyclic response, very suitable for flying straight, even at low rotor head speed

1) Use only high-quality receivers, preferably the most up-to-date PCM receivers. Lower-quality receivers may lead to disturbances or motor shut-offs.
2) Attach the antenna wire in such a way that it cannot touch any other wires or any parts of the helicopter except for the antenna leads in the landing bows where the antenna is meant to be attached.
3) The servo wire of the speed controller must be placed in such a way that it is isolated from any other wires.
4) Do not place any wires in the neighborhood of the tooth belt.
5) Do not use braces made from metal or any other metal parts for attaching the gyro, horizontal stabilizer or tail boom brace on the tail boom.
6) If you are using a separate BEC, attach it on the bottom side of the mainframe and lead the live wire to the receiver in such a way that it cannot touch any other wires.

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.
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.

Elevator (Tilt)
For tilting the helicopter , use the ele v ator function. F or tilting f orward, the two aileron servos mov e down­ward and the backward elevator servo moves upward. The elevator servo moves twice as much as the two aileron servos.

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 rev erse 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.

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 mix ed 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.
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.

For setting the respective pitch v alues, please use a pitch gauge. The values for minimum and maximum can be specified in the menus of the transmitter.

The center position of the sticks in your R/C radio corresponds to 0° pitch of the rotor blades. At 0° pitch, all levers (servo arms, washout lever, mixing arms) should be in horizontal position. At 0° pitch, the swashplate is in center position, allowing the same travel in upward (positive pitch) and downward (negative pitch) direction. This setting results in a linear pitch curve, which is ideal for 3D-style flying. Pilots who wish to fly with less negative pitch should reduce the pitch curve to approx. -3° pitch. Note that with this latter set-up the sticks are not at center position for hovering.

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 swash-plate does not hit the maximum of its tra vel. This can hav e 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. Mo v 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.
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.
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.
LOGO 10 3D

16 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 for 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 xpensive 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 an incorrectly programmed throttle curve reduces performance and can lead to overheating of the motor and the speed controller.
Rotor speed control with governor (RPM regulation mode)
A speed controller with governor function keeps the rotor head speed constant, independent of flight attitude (ascending, descending, hovering). It is not necessar y to program a throttle curve. The head speed is simply controlled on the radio transmitter using a switch or lever. Important:
1) Governor mode must be activated in the speed controller first (see manual of the speed controller)
2) In governor mode, the servo wire of the speed controller must not be connected to the throttle channel. Use a free channel in your radio to connect the servo wire.

17 Rotor Blades
Carbon Rotor Blades
Rotor blades made from glass-fi­ber-enhanced plastic or carbon are typically in ready-to-fly condition when new. It will only be necessary to adjust blade tracking.
Wooden 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.

18 Final Pre-Flight Check
18.1 Direction of Main and Tail Rotation
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 ery 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.
Prior to the first flight double-check the direction of rotation of the main rotor head and the tail rotor.

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.)
