1. Charging On-board Li-Po Batteries:
Use the supplied battery charger for the on-
board Li-Po battery in the helicopter. This
charger will automatically give the correct
charge.
Plug the charger to the battery before plugging
the charger into power point if the power point
is not switched off.
At the start of the charge the diode on the
charger will glow bright RED. After a little over
one hour this light will change to GREEN,
indicating that the battery is fully charged.
Never leave the battery charging unattended.
Never leave the fully charged battery on the
charger.
Since the battery is single cell, the risk of
voltage imbalance between cells as can occur
in multi-cell Li-Po batteries is not an issue.
Make sure the charger plug is mounted the
correct way. The plug should go in without any
significant resistance when it is the correct way.

2. Transmitter Batteries:
The transmitter takes 8 AA cells (not supplied).
It is recommended to use either Alkaline cells,
or rechargeable Ni-Cad or NiMH cells.
Use only new alkaline, or fully charged re-
chargeable batteries.
When inserting the battery holder into the
transmitter, make sure that the lugs (see Fig.C)
are pointed upwards as shown in the picture.
The charge plug on the transmitter must only be
used with rechargeable batteries. If used, make
sure that the polarity on the charger is correct.
With fully charged cells all the fields on the
power indicator on the front of the transmitter
should light up when you switch it on. If not,
then check the voltage of the batteries, and that
they all have proper contact.
