Blade BLH7100 Hoja De Datos

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

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
