Problem
Possible Cause
Solution
Helicopter control response
is inconsistent or requires
extra trim to neutralize
movement
Aircraft was not initialized properly
or a vibration is interfering with the
sensor operation
Disconnect the fl ight battery, center the control trim and
re-initialize the helicopter
Helicopter will not
respond to throttle
Throttle too high and/or throttle trim
is too high
Disconnect the fl ight battery, place the throttle stick in the
lowest position and lower the throttle trim a few clicks.
Connect the fl ight battery and allow the model to initialize
Helicopter moved during initialization
Disconnect the flight battery and re-initialize the helicopter
while keeping the helicopter from moving
Takeoff
IMPORTANT:
If the main motor or tail motor do not startup
properly when throttle is fi rst applied, 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 have become entangled within
the gears.
Place the model onto a fl at, level surface free of obstacles
and walk back 30 feet (10 meters). 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 orientations. 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 helicopter using the recom-
mended battery is approximately 4 minutes, depending on
how aggressively the aircraft is fl own.
Low Voltage Cutoff (LVC)
LVC decreases the power to the motors when the battery
voltage gets low. When the motor power decreases and
the LED on the ESC fl ashes, 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. After landing, disconnect and remove the battery
from the aircraft after use 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.
Troubleshooting Guide
Post-Flight Inspection and Maintenance Checklist
Ball Links
Make sure the plastic ball link holds the control ball, but is not tight (binding) on the ball. When a link is too loose on
the ball, it can separate from the ball during fl ight and cause a crash. Replace worn ball links before they fail.
Cleaning
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush or a dry,
lint-free cloth.
Bearing
s
Replace bearings when they become notchy (sticky in places when turning) or draggy.
Wiring
Make sure the wiring does not contact moving parts. Replace damaged wiring and loose connectors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over-tighten metal screws in plastic
parts. Tighten screws so the parts are mated together, then turn the screw only 1/8th of a turn more.
Rotors
Make sure there is no damage to rotor blades and other parts which move at high speed. Damage to these parts
includes cracks, burrs, chips or scratches. Replace damaged parts before fl ying. Verify both main rotor blades have
the correct and equal tension in the blade grips. When the helicopter is held up sideways, the main blades should
support their own weight. When the helicopter is shaken lightly, the blades should fall.
Tail
Inspect the tail rotor for damage and replace if necessary. Inspect the tail boom for any damage and replace if necessary.
Mechanics
Inspect the main frame and landing gear for damage and replace if necessary. Check the mainshaft for vertical
play. Verify that the main gear mesh is correct and that no tight spots exist in the 360 degree rotation. Inspect
all wires for damage. Replace components as necessary.
