It may be small, but what the Hubsan X4 micro quad-copter UFO lacks in size it gives back in fun factor and performance capabilities, and believe it or not, it can even be flown outdoors depending on weather. This is definitely a must have item if you are new to flying or for flipping it about just for fun. The X4 comes ready-to-fly with a 4-channel LCD display 2.4GHz transmitter that features adjustable sensitivity modes for normal or expert flight. Charging of the 240mAh Lithium polymer battery is done via a USB charge cable and takes only 30 minutes.
The X4 features a 6 axis flight control system with adjustable gyroscope delivering flight stability with super fast responses. The gyro constantly automatically adjusts the speeds of the rotors to keep the quad copter stable and this makes it much easier and fun to fly. The power comes form four core-less motors. Core-less motors are much smaller but more powerful, quieter and more responsive than conventional iron core ones. Because of less vibrations and higher output you get better flight stability, more power and better control. The quad copter is capable of flips in 4 directions - left, right, forward and backward and so much more.
The shell fully encloses the sturdy airframe to protect the main electronics. The stylish design looks amazing in flight and the ability of turning cycles, figure of eights, banking and more are simply mind blowing. The supplied four motors provide more than enough power to allow for somersaults and rolls.

- Excellent Review by James
This Quadcopter is very impressive, on receiving my package I opened the box and was immediately impressed at the detail taken to package the Hubsan X4 there is no chance of it getting damaged during transport. After taking it out of the box you start to become aware of how small it is, the pictures don't do it justice but don't let the size fool you this is a serious hobby grade quadcopter it is fast agile and is capable of aerial stunts such as banked turns and flips in all directions.
Fun Factor Price Quality Delivery Speed
Build quality is good the body is strong and the arms break loose on impact to prevent anything breaking. The motors are good and powerful if you take your hands away from the sticks it will just sit there in a stable hover. This quad files great indoors in beginner mode (a slowed down reactions) it even flies well in small spaces, but outdoors is where this thing really takes off it is so fast in expert in will out run my RC car easily when in expert the controls are sharpend up and that is when you can do filps with great precision.
Nitrotek have the best price i have seen and this quad is worth every penny. (Posted on 08/12/2013)
- Great fun, but may need some setting up Review by smeghead
What fun, more so considering the price. The X4 can be flown more aggressively, and with more freedom of movement, than coaxial helis or other aircraft in the same price bracket. It can even be flown outdoors in quite some wind. I’m amazed that something so small can fly – and climb – so fast.
Fun Factor Price Quality Delivery Speed
The “6-axis” stability controller works very well: let go of the pitch/roll control and it will level itself and slow (more or less) to a halt – this is excellent if you get confused with orientation. It will happily take off from an angled surface and automatically level itself. The aircraft is fairly robust and should survive normal crashes. Even though the radio is 2.4GHz, don’t expect much in terms of range. The controller feels cheap, and the rudder control has a rather large dead-spot in the middle and sometimes has a spongy response, but one cannot expect much at this price. I typically get flight times (gentle flight) of 8 mins 30 seconds from a full charge.
Apparently, you are meant to be able to fly the X4 straight out of the box. It should hover nicely with the trims set to centre (one or two clicks off dead-centre [where the trim ‘beep’ is higher-pitched] is OK). Unfortunately, the calibration of my unit was way off. If yours needs calibration too - DO NOT use the trims to compensate. If a lot of trim is applied, spinning (yawing) the aircraft will result with sudden speed (pitching), instability and loss of control.
The gyro calibration procedure (below) is not described in the supplied manual. To calibrate it:
1. Make sure everything is powered up, binded and working, throttle at bottom/minimum.
2. Place the unit on a level surface (the unit itself must be dead-level); make sure it remains still.
3. Enter “Expert mode” by momentarily PRESSING IN the right-hand stick of the controller (squeeze the handle INTO the controller, it will click; then red light on the Tx will flash) (if you see “SE”, then you held it in for too long).
4. Move the left-hand stick over to the bottom right (not so much that the motors spin) and hold it there. While holding…
5. Quickly wiggle the right-hand stick left, right, left, right, etc until the blue lights flash on the X4.
6. Exit “Expert mode” by again pressing in the right-hand stick
I recommend you set sensitivity to maximum (80 for all controls) for greatest speed and fun.
I already have a lot of aircraft (aerobatic helicopters, competition gliders, FPV planes, quad-copters); so far my X4 is the most fun for the price. You won’t regret buying this.
