Low Voltage Cutoff (LVC)
LVC is a function built into your ESC to protect the battery
from over-discharge. When the battery charge is low,
LVC limits power supplied to the motor. The aircraft will
begin to slow and you will hear the motor pulse. When the
motor power decreases, land the aircraft immediately and
recharge the fl ight battery.
NOTICE:
Repeated fl ying to LVC will damage the battery.
Disconnect and remove the Li-Po battery from the aircraft
after use to prevent trickle discharge. Charge your Li-Po
battery to about half capacity before storage. During
storage, make sure the battery charge does not fall below
3V per cell.
Let the aircraft climb at full throttle, into the wind, until the
aircraft gets about 300 feet (91m) above the ground, then
decrease the throttle to half (50%).
Make small and gentle stick movements to see how the
aircraft responds.
Flying with the nose pointed toward you is one of the
hardest things to do when learning to fl y. Practice fl ying in
large circles high off the ground.
If you lose orientation of the aircraft, release both sticks
and the aircraft will return to level fl ight. If in Intermediate
or Experienced Mode, switch to Beginner Mode and then
release both sticks.
Holding Pattern (HP) Mode
If at anytime the aircraft seems too far away, press and
release the HP/AL (bind) button on the transmitter.
The aircraft will maneuver to an altitude of approximately
120 feet (36m) and begin to fl y a circular pattern over the
home location.
If Airfi eld Virtual Fence mode is active, the aircraft will fl y
to approximately 120 ft (36m) altitude and fl y a circular
pattern about 100 ft (30m) in front of the home location.
The aircraft fl ies fully autonomously when HP mode is
active. The transmitter sticks have no control.
NOTICE:
As a safety precaution, Holding Pattern mode
will not function when your aircraft is below an altitude
of approximately 20 ft (6m).
To deactivate HP mode and regain control, press and
release the HP/AL button again or change fl ight modes.
IMPORTANT
: When the HP feature is activated, the
aircraft should immediately respond to the command. If
the aircraft does not respond immediately, GPS signal may
have been lost. In this case, the aircraft will have to be
fl own back to the home location manually.
Failsafe
If at anytime the aircraft loses radio connection, the
aircraft will activate Holding Pattern mode until it re-
establishes radio connection. If radio connection is not
regained, the aircraft will land near the takeoff location as
in AutoLand mode.
If radio connection is lost while the aircraft is already in Hold-
ing Pattern Mode, the aircraft will circle for approximately
35 seconds and then set up to land as in AutoLand mode.
In fl ight
NOTICE:
If a crash is imminent, activate throttle hold or
quickly lower the throttle and throttle trim. Failure to do
so could result in extra damage to the airframe, as well
as damage to the ESC and motor.
When properly trimmed, the aircraft’s wing design causes a climb at full throttle without the
use of elevator.
