SAFETY PRECAUTIONS
1
This symbol indicates
possible risk of injury
or death.
Read this before assembly and operation
This symbol indicates
actions you should
stop to avoid damage.
CAUTION
STOP
As the product includes small
and sharp parts, only operate
and store out of reach of
children.
Handle cutters, nippers and
screwdrivers with care as
they can cause injury.
Use goggles for safety.
High speed spinning rotors
are very dangerous if
close to the face.
Do not store in high temperature
or humidity for extended
periods as this may damage
or deform the model.
When not in use or after
use, always switch power
OFF, then disconnect and
remove batteries.
This will stop batteries from
leaking or overheating.
Do not get too close to spinning
rotor as this can result in serious
injury. Always keep a distance of
at least 5 meters.
Only use the specified batteries.
Do not insert batteries in wrong
polarity or modify batteries as
this may cause overheating or
damage.

before touching.
Antenna point can
cause injury.
Keep antenna away
from people's faces and
do not wave antenna

Do not operate your
model on the same
band (frequency) as
other models close by.
This will cause loss
of control.
Do not operate model

■Charging the Nickel Metal Hydride Battery (Ni-MH)
Charging time is about 10 ~ 12 hours. As this charger does not have an automatic cut off function, do not charge for more than 15 hours.
(Charging for more than 15 hours is dangerous). A fully charged battery will produce about 5 minutes of flight time.
■Assembling the Safety Bar
An Ni-MH battery is subject to wear & tear. Flight times may vary depending on battery charge, battery age and external temperature.
If flight times become very short, change to a new Ni-MH battery.

・Do not short circuit the charger terminals.
・Operate the charger in normal temperatures (about 23℃) as much as possible.
・Keep away from vibration while charging. Charging may not be possible with poor contact.
・If battery becomes hot while charging, unplug the charger from the power socket.
Safety Bar prevents model from flipping over, but also reduces flight time and motor life.

Slow flashing of the power lamp means the safety
mechanism is working.
Movement of the throttle stick will not rotate main
rotor. At this point, check the movement of the
elevator and aileron.
