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.
Holding Pattern Mode
If at anytime the aircraft seems too far away, press and release the
AutoLand 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 approxi-
mately 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.
Loiter Mode
Press and release the AutoLand button twice time to enter loiter mode. In Loi-
ter Mode the aircraft will begin circling the the point in the sky it is occupying
when Loiter is activated. The altitude and location of the loiter can be adjusted
with fl ight controls while the aircraft is in this mode, the model will resume
Loiter Mode after controls are released.
NOTICE: As a safety precaution, Holding Pattern and Loiter mode will not
function when the aircraft is below an altitude of approximately 20 ft (6m).
To deactivate Holding Pattern or Loiter Modes and regain control, press and
release the AutoLand button again or change fl ight modes.
IMPORTANT: When the Holding Pattern or Loiter 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 Hold-
ing 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 Holding Pattern Mode,
the aircraft will circle for approximately 35seconds and then set up to land as in
AutoLand mode.
Flight Patterns (BNF with FPV)
NOTICE: If a crash is imminent, activate throttle cut 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.
