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. Verify the boom support bolts are tight and the
plastic ends adhere to the carbon support rods. Verify the tail motor bolts, tail rotor adapter bolts and tail motor
mount bolts are properly tightened. 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 verti-
cal play and adjust the locking collar if necessary. Verify that the main gear mesh is correct and that no tight
spots exist in the 360 degree rotation. Inspect all wires for damage and replace as necessary.
Takeoff
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.
Typical fl ight time for the included battery is approximately 10 minutes
.
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 move-
ment.
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.
Low Voltage Cutoff (LVC)
LVC decreases the power to the motors when the battery voltage gets low. When the motor power decreases and the red
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 will 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.
