Prefl ight Checklist

1. Charge the fl ight battery.
2. Install the fl ight battery in the aircraft
(once it has been fully charged).
3. Bind the aircraft to the transmitter.
4. Make sure the linkages move freely.
5. Perform the Control Direction
Test with the transmitter.

6. Adjust the center of gravity.
7. Perform a radio system Range Check.
8. Find a safe and open area.
9. Plan fl ight appropriate for fl ying location
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The aircraft’s ESC
protects the fl ight battery from over-discharge using
Low Voltage Cutoff (LVC).
Once the battery discharges to 3V per cell, the LVC
will reduce the power to the motor in order to leave
adequate power to the receiver and servos to land
the airplane.
When the motor power decreases, land the aircraft
immediately and replace or recharge the fl ight
battery.
Always disconnect and remove the Li-Po battery
from the aircraft after each fl ight. Charge your Li-Po
battery to about half capacity before storage. Make
sure the battery charge does not fall below 3V per
cell. Failure to disconnect the battery will result in
trickle discharge.
For your fi rst fl ights, set your transmitter timer or
a stopwatch to 8 minutes. Adjust your timer for
longer or shorter fl ights once you have fl own the
model. Flights of 10 minutes are achievable with
the recommended battery if using proper throttle
management.
NOTICE: Repeated fl ying to LVC will damage the
battery.
Battery Selection
We recommend the E-fl ite 450mAh 2S 7.4V 30C
Li-Po, 18AWG JST (EFLB4502SJ30) battery. If using
another battery, it must be at least a 20C 430mAh
battery. Your battery should be approximately the
same capacity, dimensions and weight as the
recommended Li-Po battery to fi t in the fuselage
without changing the center of gravity.
