Post-Flight Inspection and Maintenance Checklist
√
Cleaning
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush or
a dry, lint-free cloth.
Motors
Replace the motor when the model will not fl y steady or veers off when doing a climb out.
Wiring
Make sure the wiring does not block 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.
Propellers
Make sure there is no damage to the propellers or other parts that move at high speed. Damage to
these parts includes cracks, burrs, chips or scratches. Replace damaged parts before fl ying.
Troubleshooting Guide
Problem
Possible Cause
Solution
Quadcopter control response is
inconsistent or requires extra trim
to neutralize movement.
Aircraft not initialized on a level surface.
Disconnect the fl ight battery, center the control
trim and re-initialize the quadcopter.
Battery not correctly placed in
battery slot.
Adjust battery position so quadcopter balances
in the center of the frame.
Quadcopter will not respond to
throttle.
Throttle too high and/or throttle trim is
too high.
Reset controls with the throttle stick
and throttle trim at the lowest setting.
Quadcopter moved during initialization.
Disconnect the flight battery and re-initialize
the quadcopter while keeping the quadcopter
from moving.
Throttle channel is reversed.
Disconnect fl ight battery, reverse the throttle
channel on the transmitter,
recconnect fl ight battery.
Quadcopter does not function
and smells burnt after connecting
the fl ight battery.
Flight battery connected with the wrong
polarity.
Replace the 5-in-1 board. Connect the fl ight
battery noting proper polarity.
Quadcopter has reduced fl ight
time or is underpowered.
Flight battery charge is low.
Completely recharge the fl ight battery.
Inadequate power to fl ight battery charger.
Use a different USB power source for the
charger.
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 during
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 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.
LED on the receiver fl ashes
rapidly and the quadcopter will
not respond to the transmitter
(after binding).
Less than a 5-second wait between
fi rst powering on the transmitter and
connecting the fl ight battery to the
quadcopter.
Leave the transmitter powered on. Disconnect
and reconnect the fl ight battery to the
quadcopter.
The quadcopter is bound to a different
model memory (ModelMatch™
transmitters only).
Select the correct model memory on the
transmitter. Disconnect and reconnect the fl ight
battery to the quadcopter.
Flight battery or transmitter battery charge
is too low.
Replace or recharge batteries.
Aircraft or transmitter is too close to
large metal object, wireless source or
another transmitter.
Move aircraft and transmitter to another
location and attempt connecting again.
Crashes immediately upon lift-off
Propellers in wrong locations or
incorrect fl ight mode selected.
Ensure propeller direction and motor
direction are correct.
