• In the event of a crash, you must quickly and safely disconnect and remove the battery from the model, then place it in a safe, open area
away from flammable materials to observe it for at least 15 minutes.
• Always store the battery at room temperature and approximately ½ charge for best results.
• When transporting or temporarily storing the battery, the temperature range should be between 40 to 120 degrees Fahrenheit. Do
not store the battery or helicopter/transmitter in a car or direct sunlight whenever possible. If stored in a hot car, the battery can be
damaged or even catch fire.
• Do not over-discharge the battery. Discharging the battery too low can cause damage to the battery resulting in reduced performance
and duration.
• The battery provided offers balancing leads. The typically hooks up to a battery balancer during the charging cycle. Although not neces-
sary, it is recommended to charge your battery with a battery balancer. This will prolong the life of the Li-Po battery.
The 75-amp brushless ESC installed in your Swift 100% RTF model features a “soft” low voltage cutoff (LVC) that occurs when the battery
reaches 14.4V under load. When the soft cut-off occurs, the ESC will automatically reduce power to the motor (regardless of the power
level you have set with the throttle stick/curve) in order to prevent the voltage of the battery from dropping to below 14.4V. After the
power is reduced and the voltage “rebounds” (rises) to above 14.4V, the ESC will automatically return power to the motor until the battery
reaches 14.4V again. This process will continue to repeat, sometimes causing the motor/power to “pulse” rapidly, helping to provide
a visual and/or audible indication of the low battery voltage. However, in some cases it may be difficult to detect pulsing of the motor/
power, so we suggest that you be extremely aware of the power level of the Li-Po battery during flight. If at any time the helicopter begins
to require more throttle than typical to maintain hover or flight, or has lost significant power, you must land the helicopter IMMEDIATELY
to prevent a sudden loss in power that could result in a crash.
Although the soft LVC of the ESC will help to prevent “deep” (below 9V; 3V per cell) over-discharge of the battery, it is not recommended
that you continue to run the motor for an extended length of time after landing and/or noticing a loss of power. Routinely discharging
the battery to 9V can still cause permanent damage to the battery, resulting in shortened flight times, loss of power output or failure of
the battery entirely.
It is important that you only charge the included 4S 3300mAh Li-Po Battery with the included charger or a comparable 4S Li-Po char-
ger. Attempting to charge the battery using a charger not suited to charge at least a 4 cell Li-Po battery could result in serious damage.
Please familiarize yourself thoroughly with the Battery Warnings and Guidelines section before continuing. NEVER charge the battery
unattended.
Note:
The Li-Po battery included with your Swift 100% RTF will arrive partially charged. For this reason the initial charge may only take approxi-
mately 30-50 minutes.
