Troubleshooting Guide
Problem Possible Cause Solution
Nano QX 3D control response is
inconsistent or requires extra trim
to neutralize movement
Aircraft not initialized on a level surface
Disconnect the flight 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
Nano QX 3D 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
Nano QX moved during initialization
Disconnect the flight battery and re-initialize the
Nano QX 3D while keeping the quadcopter from
moving
Throttle channel is reversed
Disconnect flight battery, reverse the throttle
channel on the transmitter, reconnect flight
battery
Nano QX 3D does not function
and smells burnt after connecting
the flight battery
Flight battery connected with the wrong
polarity
Replace the 4-in-1 board. Connect the flight bat-
tery noting proper polarity
Nano QX 3D has reduced flight
time or is underpowered
Flight battery charge is low Completely recharge the flight battery
Inadequate power to flight battery charger Use a different USB power source for the charger
Flight battery is damaged
Replace the flight battery and follow the flight
battery instructions
Flight conditions might be too cold
Make sure the battery is warm (room tempera-
ture) before use
Problem Possible Cause Solution
LED on receiver flashes 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 flight 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 flashes
rapidly and the Nano QX 3D will
not respond to the transmitter
(after binding)
Less than a 5-second wait between first
powering on the transmitter and connecting
the flight battery to the Nano QX 3D
Leave the transmitter powered on. Disconnect
and reconnect the flight battery to the Nano
QX 3D
The Nano QX 3D is bound to a different
model memory (ModelMatch™ transmit-
ters only)
Select the correct model memory on the trans-
mitter. Disconnect and reconnect the flight bat-
tery to the Nano QX 3D
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 flight mode selected
Make necessary adjustments
