CAUTION:
Unless the instructions that came with your radio
system state differently, the
initial
charge on
new NiMH
transmitter batteries should be done for 15 hours
using
the slow-charger that came with the radio system
.
This will “condition” the batteries so that the next charge
may be done using the fast-charger of your choice. If the
initial charge is done with a fast-charger the batteries may
not reach their full capacity and you may be fl ying with
batteries that are only partially charged.
If the transmitter comes with LiFe batteries, be sure to
follow the instructions included with the transmitter and
use the correct charger designed to charge LiFe batteries.
Ground Check and Range Check
Follow the radio manufacturer’s instructions to ground check
the operational range of your radio, before the fi rst fl ight of
the day. This should be done once with the motor off and
once with the motor operating at various speeds. If the control
surfaces do not respond correctly,
do not fl y!
Find and correct
the problem fi rst. Look for loose servo connections or broken
wires, corroded wires on old servo connectors, loose motor
connectors or try relocating the receiver antennas away from
the motor battery.
SAFETY PRECAUTIONS
ELECTRIC MOTOR SAFETY PRECAUTIONS
WARNING:
Once the motor batteries are connected the
electric motor can start at any time. Make sure the fail safe
is set on your radio to prevent the motor from starting if the
signal is lost.
WARNING:
Read the entire instruction sheet included with
your motor batteries. Failure to follow the instructions could
cause permanent damage to the battery and its surroundings
and cause bodily harm!
WARNING:
Get help from an experienced pilot when learning
to operate electric motors.
ALWAYS
switch on the transmitter fi rst. Then, connect the
motor battery. After fl ying, unplug the motor battery fi rst, then
switch off the transmitter.
ALWAYS
keep these items away from the prop: loose clothing,
shirt sleeves, ties, scarfs, long hair or loose objects such
as pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.
ALWAYS
keep your face and body as well as all spectators
away from the plane of rotation of the propeller as you run
the motor.
ALWAYS
wear safety glasses when operating the motor.
ALWAYS
remove the propeller if the motor batteries will be
connected when working on your plane.
ALWAYS
remove the batteries when charging.
ALWAYS
follow the charging instructions included with your
charger for charging LiPo batteries. LiPo batteries can cause
serious damage if misused.
ALWAYS
unplug the motor batteries fi rst.
ALWAYS
use a LiPo approved charger.
ALWAYS
set the charger’s output volts to match the battery
volts.
ALWAYS
charge a LiPo battery in a fi reproof location.
ALWAYS
charge through the “charge” lead.
ALWAYS
KEEP OUT OF THE REACH OF CHILDREN.
ALWAYS
remove the batteries from the plane after a crash.
Set them aside in a safe location for at least 20 minutes. If
the batteries are damaged in the crash they could catch
fi re. If the battery starts to swell, quickly move the battery
to a safe location, preferably outside. Place it in a bucket,
covering the battery with sand. Never use water to try and
put out a LiPo fi re.
NEVER
operate the motor in an area of loose gravel or sand;
the propeller may throw such material in your face or eyes.
NEVER
touch the motor during or right after operation. The
motor may be HOT!
NEVER
switch off the transmitter with the motor batteries
plugged in.
NEVER
use a NiCd/NiMH peak charger to charge a LiPo
battery.
NEVER
charge in excess of 4.20V per cell unless the battery
is rated for a higher voltage.
NEVER
charge through the “discharge” lead.
NEVER
charge at currents greater than 1C unless the battery
is rated for a higher charge rate.
NEVER
trickle charge a LiPo battery.
NEVER
allow the battery temperature to exceed 150 degrees
F [65 C].
NEVER
disassemble or modify the pack wiring in any way
or puncture the cells.
NEVER
discharge below 3.2 V per cell.
NEVER
place the battery or charger on combustible materials
or leave it unattended during charge or discharge.
NEVER
charge the batteries in the plane.
