Thank you for purchasing the exciting, super small Blade nano QX. The nano QX is packed full of advancedfeatures that may seem in contrast to its diminutive size. Despite being 18 grams, the nano QX is laden with the

latest SAFETM (Sensor Assisted Flight Envelope) technology that offers impressive fl ight performance with an agility mode 

for aerobatics and a stability mode with self-leveling. In stability mode you only have to control throttle, the aircraft will 

return to a hover on its own. In stability mode the bank angle is also limited, making it easy to fl y the aircraft without 

having to worry about over-control. In agility mode the nano is capable of fl ips, rolls and more, and the aircraft does not 

limit the bank angle. 

The nano QX is easy to manage, exciting to fl y, and durable enough to take the punishment. Built-in prop guards help 

prevent prop strikes so you can keep fl ying even if you bump into a wall, direct drive motors keep operation quiet and 

maintenance simple, and the frame is lightweight yet rigid, lending the nano QX remarkable durability. Be sure to read

this manual before you fl y to fully understand the features this tiny aircraft contains, this will maximize your fun and 

ensure safe operation.

Charging Warnings
7 EN

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V, the battery may become damaged and may no longer accept a charge. The 

nano QX 4-in-1 control unit protects the fl ight battery from over-discharge using Low Voltage Cutoff (LVC). Before the battery charge decreases too much, LVC becomes active. Power to the motors decrease and the LED on the 4-in-1 control 

unit blinks, showing some battery power is reserved for fl ight control and safe landing.

When the motor power decreases, please land the aircraft immediately and recharge the fl ight battery. 

Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. During storage, make 

sure the battery charge does not fall below 3V.

NOTICE: Repeated fl ying to LVC will damage the battery. 

Installing the Transmitter Batteries (RTF)

Install 4 AA batteries into the transmitter, noting polarity. Replace the

transmitter batteries when the power LED fl ashes and the transmitter 

beeps.

Transmitter and Receiver Binding

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifi er) code of a 

specifi c transmitter. You need to ‘bind’ your chosen SpektrumTM or DSM2 ®/DSMX ® technology equipped aircraft 

transmitter to the receiver for proper operation. If you purchased an RTF model, the transmitter is bound to the 

model at the factory.

To bind or re-bind your nano QX to your chosen transmitter, please follow the directions below.

General Binding Procedure

1. Disconnect the fl ight battery from the quadcopter.

2. Select a clean model memory on your transmitter (computer radios only). 

3. Select Acro or Airplane model type on your transmitter.

4. Make sure all servo reversing is set to Normal on your transmitter.

5. Center all trims on your transmitter.

6. Power off the transmitter and move all switches to the 0 position. Move the throttle to the low/off position.

7. Connect the fl ight battery in the quadcopter. The blue LED on the 4-in-1 control unit fl ashes after 5 

seconds.

8. Put the transmitter into bind mode while powering on the transmitter.

9. Release the bind button/switch after 2–3 seconds. The quadcopter is bound when the blue LED on the 

4-in-1 control unit turns solid.

10. Disconnect the fl ight battery and power the transmitter off.

CAUTION: When using a Futaba® transmitter with a Spektrum DSM2/DSMX module, you must reverse the 

throttle channel and rebind. Refer to your Spektrum module manual for binding and failsafe instructions.

Revolutionary SAFETM (Sensor Assisted Flight Envelope) technology uses an innovative combination of multi-axis sensors 

and software that allows model aircraft to know its position relative to the horizon. This spatial awareness is utilized to create 

a controlled fl ight envelope the aircraft uses to maintain a safe region of bank and pitch angles so you can fl y more safely. 

Far beyond stability, this level of protection offers multiple modes so the pilot can choose to develop his or her skills with a 

greater degree of security and fl ight control that always feels crisp and responsive. 

SAFE technology delivers:

• Flight envelope protection you can enable at the fl ip of a switch.

• Multiple modes let you adapt SAFE technology to your skill level instantly.

Best of all, sophisticated SAFE technology doesn’t require any work to enjoy. Every aircraft with SAFE installed is ready to use 

and optimized to offer the best possible fl ight experience.

Flight Mode and Rate Selection – RTF

The nano QX RTF model comes with the Blade MLP4DSM transmitter. 

This transmitter’s fl ight mode selection feature lets the pilot change 

between stability mode and agility mode. 

• When powered on, this transmitter is automatically in

stability mode and high rate.

• Change fl ight modes by pressing and releasing the left control stick 

while the transmitter is powered on. Change rates by pressing and 

releasing the right control stick.

• In low-rate mode, the controls cannot reach their maximum values. 

This mode is typically preferred by pilots looking for smoother/

easier control response during fi rst time use.

• In high-rate mode, the controls can reach their maximum values. This mode is typically preferred by experienced 

pilots who are ready for fast forward fl ight and aerobatic maneuvers (loops, rolls, etc.).

• Stability mode is shown by the fl ight control board on the quadcopter glowing solid blue. When fl own in stability 

mode, the nano QX will limit the bank angle with full control input and return the aircraft to a neutral fl ight position 

when you release the elevator/aileron stick. This mode is typically preferred by pilots during fi rst time use.

• Agility mode is shown by the fl ight control board on the quadcopter glowing solid red. When fl own in agility mode, 

the model will not return to a neutral fl ight position when you release the controls. This mode is typically preferred 

by experienced pilots who are ready for fast forward fl ight and aerobatic maneuvers (loops, rolls, etc.).

Flight Mode Selection – BNF

If you purchased a BNF nano QX, the channel 6 switch on your transmitter will select fl ight modes. When the fl ight 

control board on the quadcopter is solid blue, the fl ight mode is set to self-stabilizing mode. When the light is solid red, 

the quadcopter is in agility mode. See the table on the following page for specifi c setup information.

4-in-1 Control Unit Function

The unique Control Unit installed in your nano QX is a lightweight combination of main motor electronic speed controls 

(ESCs), mixers, the SAFE sensor unit, and a DSM2/DSMX receiver. The 4-in-1 unit is also equipped with blue and red 

status indicator LEDs.

• Before each fl ight, ALWAYS power on the transmitter before connecting the fl ight battery to the 4-in-1 unit. After each 

fl ight, disconnect the fl ight battery from the 4-in-1 unit before powering off the transmitter.

Connecting the fl ight battery before powering on the transmitter can start the binding process. Please see the Transmitter 

and Receiver Binding section of this manual for more information.

• The 4-in-1 unit will arm the motors when the throttle stick is in the lowest possible position and the throttle trim is at 

the middle or a lower than middle position (the middle position is indicated by a longer than usual beep/tone). If this is 

the fi rst test fl ight, or a test fl ight following repairs, also center the rudder, aileron and elevator trims.

• With the transmitter turned on and the transmitter LED glowing solid RED, it is safe to connect the fl ight battery to the 

4-in-1 unit.

• Connect the fl ight battery to the 4-in-1 unit.

• After the fl ight battery is connected, place the nQX on a level surface. The 4-in-1 unit status LED should glow solid 

BLUE within a few seconds.

DO NOT move, sway or pretend to fl y the quadcopter after connecting the fl ight battery. This movement can stop unit 

initialization and SAFE calibration. If the quadcopter is moved before the 4-in-1 unit status LED glows solid BLUE, 

disconnect then connect the fl ight battery to the 4-in-1 unit.

• When the 4-in-1 unit status LED glows solid BLUE, the control unit is initialized and ready for fl ight. 

• As long as you set the throttle stick and trim to the correct positions during the initialization process, the ESC or motors 

will be armed. Use caution because after arming, as propellers will turn at throttle stick input.
EN 16

• After confi rming the rotor blades rotate in the correct direction, test the motor response controls.

• Adjust the throttle to a low level of power where the quadcopter begins to get “light” on its landing skids. 

• Move the rudder stick a small amount to the right. The nose of the quad-copter should start to rotate

to the right (clockwise).

• Move the rudder stick a small amount to the left. The nose of the quadcopter should start to rotate to the left

(counter-clockwise). If the nose moves to the right, please refer to the Troubleshooting Guide.

• Move the elevator control stick forward. The two REAR landing skids should lift from the fl oor.

• Move the elevator control stick backward. The two FRONT landing skids should lift from the fl oor.

• Move the aileron stick right. The two LEFT landing skids should lift from the fl oor.

• Move the aileron stick left. The two RIGHT landing skids should lift from the fl oor.

• When rotors turn correctly and respond correctly to controls, your nano QX is ready for its fi rst fl ight!

First Flight 

• Increase the throttle until the model is approximately 2 ft. (600mm) off the ground in a low-level hover and concentrate 

on balancing the throttle stick’s position so that the nano QX holds a steady hover altitude. In some cases, you may 

need to make a few short “hops” to an altitude of just a few inches until you become familiar with the control inputs 

and trim settings required to maintain a steady hover and altitude. 

The nano QX requires minor throttle adjustments to maintain its altitude in hover. Remember to keep these throttle

adjustments as minimal as possible. Large adjustments could result in a loss of control and/or a possible crash.

• While attempting to establish a low-level hover, check to see if any trim adjustments are required to help keep the 

nano QX from constantly drifting in various directions. If you fi nd that it constantly drifts without any directional control 

input, land the model before making any adjustments to the trim settings. Additional details regarding the

location and function of the trim buttons are in the “Understanding the Primary Flight Controls” section of this manual.

– If the nose of the nano QX rotates to the left or right, adjust the rudder trim.

– If the nano QX continually drifts forward or backward, adjust the elevator trim.

– If the nano QX continually drifts to the left or right, adjust the aileron trim.

Continue making minor trim adjustments until the machine hovers at a low altitude with very little drifting and directional 

control input. If the nano QX is your fi rst multicopter or helicopter, seek the help of an experienced pilot to trim the model 

for you before making your fi rst fl ight.

• With your nano QX properly trimmed and maintaining a stable low-level hover, practice using the rudder, elevator and 

aileron controls to familiarize yourself with the machine’s responses to control inputs. Remember to keep the control 

inputs as minimal as possible.

Flying the nano QX
17 EN

TIP: These are all possible with the RTF transmitter. When using a computer transmitter, however, increase the 

travel beyond 100% on aileron, elevator or rudder for maximum control authority.

• Forward Flight

• Backward Flight

• Skidding Takeoffs

• Pirouettes

• Spot Landings

• Skidding Landings 

• Circuits (Circles)

• Figure 8s

• Flips and Rolls

Once you have gained experience and confi dence in hovering the nano QX, you can attempt more advanced 

maneuvers including:

• When comfortable with low-level hovering, you can transition to hovering and fl ying the nano QX at higher altitudes of 

three to four feet. At these higher altitudes, you will become comfortable with the fl ight characteristics of the aircraft.

• Don’t be afraid to set the nano QX down on the ground quickly by lowering the throttle when approaching walls or 

other obstacles to help prevent propeller strikes.

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 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.
