Troubleshooting Guide
Problem
Possible Cause
Solution
Helicopter control response
is inconsistent or requires
extra trim to neutralize
movement
Aircraft was not initialized prop-
erly 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 initial-
ization
Disconnect the flight battery and re-initialize the heli-
copter while keeping the helicopter from moving
Helicopter has reduced
fl ight time or is under-
powered
Flight battery charge is low
Completely recharge the fl ight battery
Flight battery is damaged
Replace the fl ight battery and follow the fl 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 dur-
ing binding process
Power off the transmitter. Move the transmitter a larger
distance from the aircraft. Disconnect and reconnect
the fl ight battery to the aircraft. Follow the binding
instructions
Bind switch or button was not
held while transmitter was pow-
ered 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 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 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.
