mQX tx


The main features of mQX are:

  • AS3X 3-axis stabilization technology
  • Can be flown in X as well as + configurations
  • 4-in-1 DSM2 receiver/mixer/ESC/AS3X sensor unit
  • Potent 8.5mm brushed motors with drive gear guards
  • You don’t need to buy anything extra for mQX RTF


mQX comes with 3.7V 1S 500mAh Li-Po battery. First plug the power converter to a 100AC outlet. Link it to the Celectra 1-cell charger to receive 6V DC current. Plug the short connector wire which makes the JST connector of the battery connect to the charger. Don’t ever plug the battery in the charger if the charger is not linked with the power converter with the converter plugged in a working electrical outlet. If you do so, your battery will be drained by the non-powered charger. Also don’t ever leave the battery unattended while being charged. Make settings of the charger for .7 amps which is the maximum. Push the large middle button and red LED below the .7 amp indicator will start sparkling to show that charging is in process. If all the red LEDs are flashing in sequence, the battery can be left or used for a bit more extra charge.

“X” and “+” Configurations

X configurationplus configurationBoth the RTF and BNF versions of mQX come in X configuration. The X configuration comes with two white propellers and the body of the quad is lined up with its front facing between these two propellers. Thus the body looks as if it is in the center of an X, so the name.

To change it to + configuration, take off the body from the frame while you look at the quad from above and squeeze it anticlockwise in 45 degrees and reinstall it on the frame making use of the holes on the front, back and center of the sides of the fuselage. With the screwdriver, take the small screw off on the side of the white propeller which is now to the right side of the quad and install the black extra propeller matching in shape. (Ensure about the matching shape since there are clockwise as well as anticlockwise black propellers provided.) Be careful while removing the small screw as no additional screws are supplied. After you change the configuration, you have to rebound mQX to the transmitter in a specific way.

Rebinding mQX to the Transmitter for + Configuration

Plug the flight battery into the quad. Using the supplied transmitter, press the left joystick and turn the TX on while holding the left stick still down. After 2 seconds, leave the left joystick to come up and apply right rudder full. After around five seconds the mQX will give three small twinkles and a space which shows that the Plus configuration has been successfully done. If a solid blue is seen, it means it still is in the X configuration and you will have to repeat the binding process. If your transmitter is different, follow the directions of it binding process and apply full right rudder as fast as possible.

To bind back in the X configuration, follow the binding instructions but apply a hard left rudder. The blue light on the quad should become solid blue.

Flying Performance

mQX has an inherent stability that is offered by the two propellers set diagonally across each other and rotate in clockwise direction while the other two rotate anticlockwise. So, one of the two white propellers is meant for clockwise rotation and the other for anticlockwise rotation and the black propellers and the two sets of extra propellers too are also designed in the same way, i.e. one for clockwise and the other for anticlockwise direction.


It is better to start with the X configuration with the quad facing away, thus the pair of black propellers is nearest to you and the white ones are away from you. This will make the direction of the quad same as yours – i.e. left and right, and forward and backward. It is tricky to keep perfect orientation for successful flying of mQX. The left stick supplies both rudder and throttle. Rudder lets you turn the mQX in place to the left or right. The right stick elevator lets you control forward and backward flight, while aileron controls side-to-side flight.

Another word of caution is about the transmitter that it is in high rate when it is first switched on. So, for starting, low rates are recommended. Just press the right stick to switch to low rates. When you want to get back to high rate, press the right stick again.

mQX presents a superb hover when you just apply throttle. And when you reduce the throttle just while hovering, you can land it. On an even surface it just slides and it’s fun to watch the touch-and-go, more than vertical touch-and-go.

Acrobatic Performances and Flying in the Open

mQX gives you full satisfaction of aggressive flying and a lot of tricks. And you can easily experiment because the durability of the bird is excellent. You can have nearly as many crashes and can learn to have acrobatic performances.

While flying outside, you can have the best control of mQX in calm to windy conditions with a breeze at 6 mph; however, in around 8 mph difference is seen in high and low rates and it is much easier to fly at low rates. Better practice can give better control for the AS3X system though. While flying outside, you will need extra batteries too as the charger requires 6V DC.


  • Extremely durable
  • Extremely stable at low rates with a little movement
  • Extremely light-weight, responsive and nimble
  • Spare parts are easily available and affordable


  • No extra screws for propellers and the screws are very small so very likely to be misplaced


The experience level required for mQX is intermediate as rightly suggested by Blade; it is not for beginners. If you have experience of a coaxial or even better, of a FP heli, you can learn to fly a quadcopter. mQX is very responsive to bigger stick movements or high rate flying.

If you are planning to buy a FPV quadcopter, mQX can become your great trainer to try hand on. It teaches you how to control in an excellent manner.
