Maintenance of Helicopter

The most important thing for a permanent optimal success with
your new helicopter is to check and maintain every component af­ter every use. Below you will find some general steps for mainte­nance:

Main rotor checklist:

1) Regularly check the main rotor on wear. Check all components
of the main rotors, make sure there is no tolerance between linka­ges. All parts should run smoothly. No bearings should be knocked
out.

2) The O-rings lose their elasticity over time. Replace them and any
worn part on a regular basis.

3) As soon as the helicopter flies slower and does not respond
spontaneously to pitch and gas pulses review the following parts
immediately:

- Ball bearings

- Main rotor blades

- All plastic parts of the main rotor

4) Check very carefully whether the main rotors are balanced.
Both blades must be exactly equal, an increased wear can occur
and the helicopter might
reacts different in difficult flight situations if not balanced.

5) The directions of the swash plate must be exactly examined.
The levers should not be bent or cracked. The swashplate must
always be able to follow your controls exactly. Replace the swash­plate when you
discover an error.

Hull and chassis checklist:

1) Check the bearings and the support of the main rotors.
After about 100 flights, you should replace these parts with new
ones. If you frequently
perform 3-D flights, you need to maintain more often.

2) The bearings in the hull should be checked, cleaned and lubri­cated after about 50 flights. Carry out the same procedure for the
gears. Make sure everything sits secure and nothing has loosened.

3) Also, the belt drive for the tail rotor must be regular checked
and examined if any damages occurred. It should not be stretched
or worn, no tooth should be worn. If the belt drive is not in 100%
working condition, it has to be changed.

Linkages and connections

Make sure the linkages run smoothly and are tight at the same
time. Only this can ensure that the helicopter flies optimal. If you
break a rod, the helicopter will crash inevitably. Replace faulty lin­kages.

Tail rotor system

1) Clean the tail rotor on a regular basis, especially if you take off
and land in high grass.

2) Regularly inspect the tail rotor if it functions correctly. If you find
knocked out bearings, they must be replaced.

3) After about 50 flight, carefully disassemble the tail rotor and
clean all components. All worn parts should be replaced.

4) Also the tail rotor blades need to be check if they have any da­mage. If they are damaged, they need to be replaced. The tail ro­tors need to run smooth because if not, the whole helicopter might
vibrate.

Note: Only a well-maintained helicopter protects you against acci­dents and the loss of the model.

Assembly of gyro

For best performance of the gyro, please follow the steps below:

1. Even though the gyro is very well protected from vibrations, it
still has to be placed in the helicopter so that most vibrations are fil­tered. Otherwise the gyro might not work correctly. Check regularly
if the gyro is still secure in its position.

2. Make sure the connections are not tight or tense. Use the dou­ble-sided tape provided.

3. When you assemble the gyro into the helicopter, make sure the
gyro has no direct contact to metal parts. The casing does protect
from electromagnetic waves and is also conductive.

4. When you assemble the gyro, make sure it is placed so that it
has a 90° angle to the yaw axis (see image).

5. Even though the gyro is protected from variations of tempera­tures, it should not be assembled near a heat source. The neutral
position could be influenced. For example, if you decide to fly your
helicopter in the winter, make sure you let the helicopter adjust to
the temperatures outside. If you take your helicopter out of the
warm car or your warm house and do not let the gyro adjust to the

outside temperatures, the neutral position
could be influenced. Adjusting the gyro to
temperatures will take approx. 10min.

6. After switching on the helicopter, the gyro has to be initialised.
This will take approx 3 sec. In this time, no stick or lever should be
moved.

Starting up

The installed gyro is a mini gyro and therefore the setting buttons
are very small. Be very careful when adjusting settings on the gyro
and use an adequate screw driver.

1.
Connect the gyro to the rear rudder channel you will later control
on our transmitter. The other plug should be connected to the
cable for the receiver exit which controls the delay time. Connect
the servo to the exit point of the gyro.

2.
Switch settings
The ‚DS’ switch will enable you to adjust the servo to the gyro. For
digital servos, please switch the ‚DS’ button to ‚ON’. For analogue
servos use ‘OFF’
The ’NOR/REV’ switch will enable to adjust the direction of action.
It will adjust the turning direction of the rear rotor servo.
NOR = normal turning direction
REV = reveresed turning direction
If you notice that the turning direction of the servo is the opposite
way, adjust by unsing the ’NOR/REV’ switch. In addition, make sure
the gyro is working correctly by
checking the manual of the gyro.

3. Servo deflexion (limited)
The maximum servo deflexion can
be programmed by the controller
without setting it by the transmitter.

• With an increase of the setting,

the servo deflexion will also be
increased.

• If the setting is decreased, the

servo deflexion will also be decre­ased.

When adjusting, take special care that you do not set the servo to
full deflexion so that it is mechanically restricted. The servo could
be damaged. On the other hand, do not set the deflexion to low
so that the gyro is limited.

4.
Delay
Delay of the gyro can be set by the controller.

When using a digital servo, set the trimmer near ‚0’. If you use an
analogue servo, it is recommended to set the delay. Optimise your
settings for your system.
The absorption will decrease by turning your controller setting to­wards zero, turning it towards 100 will result in higher absorption.

Stick position at Hovering/Throttle 65%~70%/Pitch+5º+6º

Stick position at low/Throttle 0%/Pitch 0º

When the general flight mode is switched to 3D mode, the stick position
should be at throttle. 70%, otherwise it will cause the gear stuck. When
the mode is switched from 3D to general 70%, otherwise it will cause
the gear stuck. When the mode is switched from 3D to general helicop­ter. Under 3D mode, it can obtain maximum power with the stick at the
lowest position. It can make inverted flight and other stunt actions when
the mode is switched to 3D.

Warning!

Stick position at middle/Throttle 90%/Pitch 0º

Stick position at low/Throttle 100%/Pitch-9º~11º

Note:

• If the pitch angle is set too high, then the helicopter can not

move properly resulting in shorter flying time.

• If your set for a high rotor RPM, then a high pitch is

recommended..

• If unsure, it is always recommended to set a low pitch. The

result is that a higher rotor head RPM is achieved and the heli
copter will fly more stable.

Important:

When flying 3D, secure the canopy with an additional screw at
the bottom of the canopy. Otherwise it can come lose and dama­ge the helicopter.

Main Rotor Adjustments

Adjustment Mark

When replacing the main rotor, it is necessary to balance
the blades first. Screw the rotor blades together as in the
illustration. The rotor blades are properly balanced when
they are suspended exactly horizontally. If not, the blades
are not in equilibrium. This is corrected by applying tape
to lighter blade.

Current track settings
To set the current track, attach a blue and red piece of tape to the rotor blades. If the current track is deflected, then it has to be adjusted by
the control rod link.

Check the following components if the drive system is not working properly:

• Check the battery pack. Make sure it is fully charged and has enough capacity.

• Check the pitch settings.

• Check the angle of the main rotor and make sure it can move smoothly.

• Make sure there are no vibrations.

• Check the tension of the drive belt.

Instructions for the use of LiPo Batteries

Technical data

Case:

The case of the cells consists of an aluminium-plasticfoil. This foil
should not be damaged under any circumstance, because this will
lead to a damaged cell. Take care of sufficient protection (i.e. vib­rations) in the model. If damaged, they might leak, avoid contact
under all circumstances.

Overcharging:

If charging does not stop because of any damage to the char­ger the battery may catch fire. Therefore supervise the charging
process frequently.

Speed charging:

Speed charging is not possible. The charging voltage for these
cells must be followed.

Charging temperature:
0 to +45 degrees outside temperature. During charge, the bat­tery should not get warmer than 70 °C. Supervise the charging
process with help of the JAMARA Thermo Scan 3000 ( Non-touch
infrared thermometer) Order No. 17 0133.

Discharging temperature:

-20 to +60 degrees: Flying in winter is therefore possible. At tem­peratures beneath 0 degrees, it is likely that the capacity may be
reduced by approx. 20% and the discharge level may be smaller
as well

Lifetime:

Very user-dependent.

Storage:

The cells need to be between half full and full charged. The sto­raging of empty cells will lead to their destruction. New cells are
therefore half full.

Charging time:

Charging will take approx. 20 min.
The incl. charger has an automatic charging stop.

Important Notice

Read the manual and the safety precautions for the
Lithium-Polymer-Cells properly.

- Litium-Polymer-Cells have no memory-effect

- Lithium-Polymer-Cells are recharged with a constant voltage and a
constant power

- Lithium-Polymer-Cells have a small self-discharging Voltage

Liability exclusion

Jamara e.K. assumes no liability in case of wrong usage or operation
of the product, respectively of all injuries.
The customer alone is in charge of the cell, this includes from the
recharging process up to the choice of place of use.
If the customer is not satisfied with the terms of usage, he may use
his right to return the unused product to the dealer.

Lithium-Polymer-Cells may only be stored and recharged, on fireproof
non-flamable grounds. Jamara e.K. recommends to recharge the cells
only with the transmitter. When using an other charger or when using
the permitted charger incorrect, no liability can be taken. Because of
their enormous power-compactivity Lithium-Polymer-Cells are flamea­ble when damaged. This can happen through extrem overcharging, a
crash or a mechanical damage etc. Therefore, it is extremly important
to supervise the recharging process. After a crash the cell/pack should
be checked carefully. For example the cell/pack could have been da­maged, but doesn‘t heat up before 30 minutes. So, in case of a dama­ge at one pack or a cell always strictly supervise.

If the cell overheats, swells, burns or smoke is coming from it,
do not touch it under any circumstances. Keep away in a safe
distance and prepare adequate extinguishing agents such as
dry powder or sand.

Safety precausions

Because of the high power compactivity (up to 150 Wh/kg) the cells
are quite dangerous and need special care! The company Jamara
excludes explicitly, all types of liability for damages, that can occure
when using the Lithium-Polymer-Cells unproperly.

- When using the battery incorrect there is a risk of getting fire- or
acid-injuries.

- Overcharging, too high power, or discharging at low level
destroys the cell.

- Protect from mechanical stress (squeezing, pushing, bending,
drilling).

- Never open or cut open, do not throw into fire, keep away from
children.

- Handle damaged or leeking battery with care. Injuries or damages
to the gear can occure.

- Under no circumstance short-circuit the device and always watch
polarity.

- Protect batteries from heat above 65 °C , mount away from hot
objects (for example exhaust pipe).

- Before storing batteries (for example in the winter) charge the
battery. Do not store in fully charged or in non charged state!

- If stored over a longer period of time, observe the power level
occasionally.

- The contents of the cell is harmfull for skin and eye.

- If the content comes into contact with skin, clean with plenty of
water and take off moisted clothes.

- If the content comes into contact with the eyes, clean with
plenty of water and consult a doctor.

Charging

1 Insert plug in AC outlet
2 Connect the battery with charger
3 Remove the battery after a full charge

When starting to charge, insert the plug to the socket first and
then connect the charging/discharging connector (not included).

Please pay attention to the charge condition during the charging
process. After charging,disconnect the battery and charge
connector (not included). Overcharging or charging the battery
improperly may cause dangerous overheated situation.
If battery’s temperature exceeds 45° please stop charging imme­diately.

In order to get optimum efficiency please do not charge the bat­tery immediately after use. Please wait until the battery cool off,
which helps to extend its lifetime and performance.
