HANDLING OF THE NiMH BATTERY PACK
NiMH batteries (Nickel-Metal Hydride) are state of
the art electric power sources with high capacity in
relation to their weight. Handling such batteries
requires special care to avoid possible hazards
and premature loss of power with regards to
charging and discharging as well as storing and
any other kinds of handling. Non-observance of
instructions and warnings can rapidly affect loss of
power, shortening of service life or defects. After
the flight and at the end of charging, the battery
may become hot. Within certain limits this is a
normal process. The 12V charger included in the
airplane set, is powered by the connector plug of a
car's cigarette lighter and features a delta peak
disconnection. This means that the current is
switched off by the equipment once the full
capacity of the battery is obtained. NiMH batteries
are very sensitive to deep discharge where the
voltage drops to less than 1V per cell; they can be
permanently damaged by this process. The
electronic speed controller (ESC) is equipped with
a safety switch that protects against under voltage
by shutting down the motor; the remaining voltage
is sufficient to maintain control in a power-off glide.
Disposal of worn out or damaged batteries
Dispose of battery properly. The durability of NiMH
battery packs depends on the kind of use and
current consumption. If a steady high current is
consumed e.g. during fast flying with high rpm,
about 250 charge / discharge cycles are possible.
A reduction in capacity will also be noticed sooner.
A worn out (only very low capacity) or damaged

is lightweight i.e. designed for lower speeds.
Wings with active control surfaces (ailerons) are
available as spare parts.
Depending on the way you fly, the voltage of your
NiMH battery pack will drop at some stage
resulting in a lower rpm of the motor combined with
reduced climbing ability of your model. As soon as
you realise this fact you should start to land.
Landing with not enough or no power is always
difficult and you may not have sufficient power to
reach your intended landing point.
Short circuits must be absolutely avoided; they can
cause great heat and melt the wire insulation and
can ignite surrounding combustible material.
If you have several batteries to charge and you
would prefer to do this at home, please visit your
special hobby dealer for details of CARSON quick
chargers. The battery pack may be rather hot after
a flight.
It is prohibited to charge the battery pack inside the
model and we recommend removal of the battery
after each flight and storage in a safe place.
battery pack (wrapper damaged, worn cable) has
to be disposed of at special disposal sites and
must not be included with normal household
rubbish.
