When a Li-Po is discharged below 3V per cell, it will not hold a charge. The ESC protects
the flight battery from over-discharge using Low Voltage Cutoff. Before the battery charge
decreases too much, LVC removes power from motor in two ways: (1) Reduces power -
ESC reduces motor power (recommended), (2) Hard cutoff - ESC instantly cuts motor
power when the pre-set Low Voltage Protection Threshold value is reached. These
settings can be changed using the ESC programing guide.
Charing the Flight Battery
Low voltage cut off (LVC)
All instructions and warnings must be followed exactly. Mishandling of Li-Po
batteries can result in fire, personal injury, or property damage.
Battery warning:
By handling, charging or using the included Li-Po battery
you assume all risks associated with lithium batteries.
If at any time the batteries begin to swell, or balloon, discontinue use immediately!
Charging or discharging a swelling or ballooning battery can result in fire.
Always store the batteries at room temperature in a dry area to extend the life of
the battery. Always transport or temporarily store the battery in a temperature range
o
40-120 F. Do not store battery or model in a car or in direct sunlight. If stored in
the battery can be damaged or even catch fire.
Never use a Ni-Mh charger. Failure to charge the battery with a compatible charger
cause fire resulting in personal injury and property damage.
Never discharge Li-Po cells to below 3V.
Never leave charging batteries unattended.
Never charge damaged batteries.
Caution:
The Battery Charger is designed to safely charge the Li-Po battery,
Charging the flight battery
When charging the battery, make certain the battery is on a heat-resistent surface, charge
the battery before assembly of the airplane. Install the fully charged battery to perform

We recommend the 11.1V 2200mAh 25C(180g/6.3oz)
Li-Po battery. If using another battery, the battery must be at least a 11.1V 2200mAh 25C
battery. Your battery should be approximately the same capacity ,dimension and
weight as the 11.1V 2200mAh 25C Li-Po battery to fit in the fuselage without changing
the center of gravity significantly.
5. The specification of the model list as fellow:
The ESC included with the Spitfire has a safe start. If the motor battery is connected to
the ESC and the throttle stick is not in the low throttle or off position, the motor will not
start until the throttle stick is moved to the low throttle or off position. Once the throttle
stick is moved to the low throttle o off position, the motor will a series of beeps.
Several beeps with the same tune means the ESC has detect the cells of the battery.
The count of the beeps equal the cells of the battery. The motor is now armed and will
start when the throttle is moved.
The motor and ESC come pre-connected and the motor rotation should be correct.
If for any reason the motor is rotating in the wrong direction, simply reverse two of the
three motor wires to change the direction of rotation.
The motor has an optional brake setting. The ESC comes with the brake switched off
and we recommended that the Spitfire be flown with the brake off . However, the brake
could be accidentally switched on if the motor battery is connected to the ESC while the
throttle stick is set at full throttle. To switch the brake off, move the throttle stick to full
throttle and plug in the motor battery. The motor will beep Move the throttle
stick to low throttle or the off position. The motor is ready to run and the brake will be
switched off.
