Consult your local laws and ordinances before choosing a
location to fl y your aircraft.
If this is your fi rst helicopter, we suggest getting assistance
from an experienced helicopter pilot or fl ying club until you are
comfortable fl ying alone.
We recommend fl ying your aircraft outside in calm winds or inside
a large gymnasium. Always avoid fl ying near houses, trees, wires
and buildings. You should also be careful to avoid fl ying in areas
where there are many people, such as busy parks, schoolyards or
soccer fi elds.
It is best to fl y from a smooth fl at surface as this will allow the
model to slide without tipping over. Keep the helicopter approxi-
mately 2ft(600mm) above the ground. Keep the tail pointed
toward you during initial fl ights to keep the control orientation
consistent. If you become disoriented while fl ying, slowly lower
the throttle stick to land softly.
During initial fl ights, only attempt takeoff, landing and hovering
in one spot.
Takeo
Place the model onto a fl at, level, obstacle free surface and
walk back 30 feet (10 meters). The model has a safety lock
which disables the throttle both at initial startup and when-
ever the model does not receive any throttle input for greater
than 10 seconds. The blue LED on the aircraft will blink
slowly to indicate the throttle is locked. To unlock the throttle
fully lower the throttle stick. Push the rudder control fully to
the right and hold for 3seconds. The blue LED on the aircraft
will fl ash rapidly indicating the throttle is active. The aircraft
is now ready for fl ight and will respond to any throttle input.
IMPORTANT: If the main motor or tail motor do not startup
properly when throttle is fi rst applied after the throttle is
unlocked, immediately return the throttle to idle and try again.
If the problem persists, disconnect the fl ight battery, check for
binding in the gear train and ensure no wires or debris have
become entangled within the gears.
Slowly increase the throttle until the model is approximately
2ft.(600mm) off the ground and check the trim so the model fl ies
as desired. Once the trim is adjusted, begin fl ying the model.
Hovering
Making small corrections on the transmitter, try to hold the
helicopter in one spot. If fl ying in calm winds, the model should
require almost no corrective inputs. After moving the cyclic
stick and returning it to center, the model should level itself.
The model may continue to move due to inertia. Move the
cycle stick in the opposite direction to stop the movement.
After you become comfortable hovering, you can progress into
fl ying the model to different locations, keeping the tail pointed
towards you at all times. You can also ascend and descend
using the throttle stick. Once you’re comfortable with these
maneuvers, you can attempt fl ying with the tail in different ori-
entations. It is important to keep in mind that the fl ight control
inputs will rotate with the helicopter, so always try to picture
the control inputs relative to the nose of the helicopter. For
example, forward will always drop the nose of the helicopter.
The average fl ight time of the aircraft using the recommended
battery is approximately 4 minutes, depending on how aggres-
sively the aircraft is fl own.
Low Voltage Cuto (LVC)
LVC decreases the power to the motors and the green LED
fl ashes slowly when the fl ight battery voltage gets low. When
the green LED fl ashes or the motor power decreases land the
aircraft immediately and recharge the fl ight battery.
LVC does not prevent the battery from over-discharge during
storage.
NOTICE: Repeated fl ying to LVC may damage the battery.
Landing
To land, slowly decrease the throttle while in a low-level hover
until the aircraft touches down. After landing, disconnect and
remove the battery from the aircraft to prevent trickle discharge.
Fully charge your battery before storing it. During storage, make
sure the battery charge does not fall below 3V per cell.
