Make sure that you have sufficient insurance cover when practising your hobby or take
out a special insurance for model aircraft. The contact address for this is Deutscher
Modellfliegerverband e.V. Rochusstr. 104 – 106, 53123 Bonn.
Only a well-maintained model will function properly. Only use approved spare parts and never
improvise with any unsuitable items.
It is the user's responsibility to ensure that the model is functioning correctly and that all nuts,
Preparations
Never start flying before you have made sure of the following points:
• Pay attention to visible damage on the model, remote control, battery charger, and lithium
battery.
• Ensure that the model is functioning correctly and that all screwed and plugged connections
are fitted precisely and tightly.
Flight operation
The model is primarily designed for indoor flights since its low weight and unstable flight
position resulting from the construction type make it very susceptible to air movements.
Moreover, the components are not dust- and moisture-proof.

General information

• If you have little or no experience with model aircraft you should practice with a flight
simulation program first.
• Ask experienced model pilots for advice with the fine settings of your model aircraft.

SAFETY PRECAUTIONS LITHIUM BATTERIES

Safety Precautions Lithium batteries:
1. General: Lithium batteries (accumulators) are energy storage devices with a high energy
density and can present risks. For this reason, particular care is needed when charging,
discharging, storing and handling. Read these instructions very carefully before first using the
battery. Do not fail to take note of the warning notices and instructions for use. Misuse can lead
to risks such as explosion, overheating or fire. Failure to observe the instructions for use leads to
early failure and other defects. The instructions should therefore be kept in a safe place and it is
essential that they are handed over to the second user if the batteries are passed on.
2. Warning notices:
• Avoid short-circuits. A short-circuit may well destroy the product. Cables and connections
must be well insulated.
• It is essential when connecting the battery to ensure that the polarity is correct.
• Original plug connectors and cables may not be cut off or changed - if need be, use an
adapter cable.
• Do not expose the battery to excessive heat or cold or to direct sunlight. Do not throw in the
fire. Do not place the battery in contact with water or other liquids.
• Charge the battery only with charging units intended for the purpose and always use the
balancer connection. It is only by using the balancer connection that optimum charging can
be ensured. If this connection is not used, charging is subject to the risks mentioned above.
Before charging, always first allow the battery to cool to ambient temperature. Never charge
while hot.
• When charging, place the battery on a non-flammable, heat-resistant support. There should
be no flammable or readily ignited objects in the vicinity of the battery.
• During charging or operation, never leave the battery unsupervised.
• Do not fail to keep to the recommended charge/discharge current.
• The battery casing must not be damaged. It is essential to avoid damage by sharp objects
such as knives or the like, from dropping, impact, bending etc. Damaged batteries may no
longer be used.
• Batteries are not toys. They should be kept away from children.
3. Charging instructions: Lithium batteries are charged according to the CC-CV procedure.
CC stands for "constant current", which is applied during the first phase of charging. Once the
bolts and screws are tightened.
Keep the model well beyond the reach of small children. They may unintentionally activate the
model and cause themselves injury with it, or they may put batteries and small parts into their
mouths and swallow them.
• The flight battery must be fully charged and correspond to the correct voltage. Only use
new/fresh batteries for the transmitter.
• Make sure that all servos respond correctly to the signals of the transmitter.
• Always check the radio operation before starting the model.
Do not fly any longer than one battery charge
Afterwards, the model must cool down for at least 5 minutes.
Then recharge the battery. Avoid deep discharge in any case.
• Familiarise yourself with the control functions of your trnasmitter.
• Start your first flights, standing behind the model and looking in the flight direction. In this
case, the control reaction equals the controlling direction.
• Also familiarise yourself with the movements of the model, when it flies towards you
(response opposite to the control direction)!
battery reaches the maximum voltage configured in the charger, it switches to CV (constant
voltage) for the second phase of charging. The battery voltage no longer increases. The charging
current now falls continuously until the battery is fully charged. The maximum charging current
for the battery is 1C (C=nominal capacity of the battery, e.g. for a battery with a nominal
capacity of 2700 mA, the maximum charging current for the battery is 2700 mA (2.7 A)). Never
charge several batteries together from a single charger. Differing states of charge and capacities
can lead to overcharging and destruction.
4. Storage instructions: Lithium batteries should be stored charged to 20-50 % of their
capacity and at a temperature of 15-18 °C. If the cell voltage falls below 3 V, they should be
recharged. Deep discharge and storage when discharged (call voltage <3 V) will render the
battery unusable.
5. General terms of guarantee: There is a legal guarantee for production and material faults
as applicable at the time of dispatch. No liability is accepted for normal wear and tear. This
guarantee does not apply for defects attributable to improper use, inadequate maintenance,
third-party interference or mechanical damage. This applies, in particular, to used batteries
and batteries clearly showing signs of use. Damage and loss of performance due to improper
handling and/or overload are not product faults. Batteries are consumables and subject to a
certain ageing. This is influenced by factors such as the charge/discharge currents, the charging
procedure, the operating and storage temperatures and the state of charge during storage.
The ageing shows itself in, among other things, an irreversible loss of capacity. In the model
field, where batteries are frequently used to supply motors, very high currents can flow from
time to time.
6. Exclusion of liability: Since we are unable to have any control over charge/discharge, handling,
compliance with assembly and operating instructions, battery replacement and its care and
maintenance, Tamiya / Carson can accept no liability for loss, damage or costs incurred. Any claim
for damages that may result from operation, failure or faulty operation or that is in any way related
thereto will therefore be refused. We accept no liability for personal injury or material damage and
their consequences that arise from our delivery.
7. Disposal instructions: Batteries are hazardous waste. Damaged or unusable cells must be
disposed of in the correct manner.
No liability for printing errors, we reserve the right to make changes!
