This is the review of MJX X100 quad UFO which I hope that will add to the info you already might have got from reviews elsewhere, which I too read regularly before buying any craft to get a detailed insight and then to decide whether to buy it really or not. So, I thought to buy this one, reading good reviews about it and I must say, it is really nice.


The package of MJX X100 contains: 1 MJX X100 quad, 1 3.7V 300mAh Li-Po battery, 1 USB charger, 1 4-CH 2.4GHz tx, 4 extra blades (2 orange or red, 2 black), 1 warranty card (valid only in China), 1 Chinese user manual.


Building Quality

X100 has got excellent building quality and durability. Some issues include the awkwardly positioned function button and the dual rate switch which make you hard to reach while flying the quad. Binding takes a longer time is another one.


The tx of this quad looks like any other transmitter, but has many unique features, which you realize when you use it.

The most interesting feature perhaps is to switch between the modes 1, 2, 3 and 4.It has tabs on the sticks’ sides which enable you to switch the function of the stick – like from throttle to elevator – and has a button below which will switch aileron with rudder.

I also liked the 6-axis mode – an equivalent of the Ladybird. You can flip the quad on PRO mode, when the aileron/elevator stick will be pushed to full.

Flying Performance

Binding of the quad was a bit lengthy process, but not unacceptable. I plugged in the battery and flew it. I hovered it not very high and it was stable with just throttle input. Then I first flew it around in NORM mode on which it became a bit faster than the LadyBird. This you will have to get used to.

The steadiness is brought about by the combination of the 3-axis gyro and 3-axis accelerometer. The quad is marvelously stable in PRO mode as it is in 6-axis mode. While giving flip, give it full elevator or aileron or press the function key. During ascent, the flip looks composed and spontaneous.

On the first flight I could fly for 8 minutes, during which it ate up a lot of power. If you try to increase the flight time, there will be low voltage cutoff, so keep many batteries handy. Here the throttle limiter comes to your aid – while turning right down, hover on say 80% throttle, so, that will keep back power to go up and fly about. When dialed up full, hover on around 50% throttle and a lot of power will be available for you. This means that when you have lower setting, the throttle range is dispersed over a larger stick movement, which even enables you to get a spot where it hovers steadily and you can also use the dial to fine tune to make it further steadier.

When I first flew it outside, it was windy, and I noticed that the 6-axis takes system takes control all the time to balance the quad’s actions caused by the wind. So, it is better to fly it under non-windy conditions.

Like most of the quads, landing of X100 is easy, but its blade keep on spinning longer after landing so don’t try to land it on your hand.day flight

Night Flight

4 LEDs on the 4 motor units (the front arms flashing between red and blue, while the back arms have both white) makes night flight excellent. Keep an eye on where the quad is heading. If you have a practice of night flying you will have a lot of fun – you can even fly it at a distance and high. If you haven’t you will have to get a little practice.

night flight


  • Durable
  • Extremely stable
  • LED lights for night flying


  • Function keys awkwardly positioned and hard to access when you are flying the quad
  • Binding takes time
  • Transmitter lacks LCD screen
  • Motors take time to spin down
  • Only Chinese manual


X100 is excellent! Its stability is great and both – beginners and pro’s – will have great fun with it, because of the ease of flying with the transmitter enabling you to switch between the modes.
