Troubleshooting Guide
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  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  ight battery, place the throttle stick in the
lowest position and lower the throttle trim a few clicks.
Connect the  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
Helicopter has reduced
fl ight time or is under-
powered
Flight battery charge is low Completely recharge the  ight battery
Flight battery is damaged
Replace the  ight battery and follow the  ight battery
instructions
Flight conditions might be too cold
Make sure the battery is warm (room temperature) before
use
LED on receiver fl ashes
rapidly and aircraft will
not respond to transmitter
(during binding)
Transmitter too near aircraft
during binding process
Power off the transmitter. Move the transmitter a larger
distance from the aircraft. Disconnect and reconnect the
 ight battery to the aircraft. Follow the binding instructions
Bind switch or button was
not held while transmitter was
powered on
Power off transmitter and repeat bind process
Aircraft or transmitter is too close to
large metal object, wireless source
or another transmitter
Move aircraft and transmitter to another
location and attempt binding again
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  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.
Bearings 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  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 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
vertical 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.
