The MJX X100 Review



Introduction (and a few words from James)
Hey everyone, I know that I've promised a review of the X100 a few weeks ago...but I've been so busy lately that I can barely find the time to do my paperwork at the hospital... let alone the review! (For those of you who are following my exciting life at the bottom of the medical pyramid, I'm doing my rotation in the Internal Medicine/Cardiology ward... not a fun place to be for both patient and doctor )

Anyways, I trust that many of you have seen Erdnuckle's excellent post on his blog about this quad...so I hope that my findings can provide another point of view or further information perhaps...into the performance and many other aspects of this great little aircraft.

Special thanks goes to Banggood (my friend Aaron especially) for providing the sample... and to you guys for reading it.
As always, questions and comments are welcome and much appreciated.

From the box

There was no damage to the box at all when it arrived at my apartment (although it has made a far shorter journey than most). Like Erdnuckle said though, everything from the box to the manual were in Chinese...which may be a problem for most of you. In the following review I'll label most of the buttons on the transmitter and highlight some of the unique functions of this quad, so hopefully the lack of an English manual won't be too much of a problem for you guys.

Box contents include:
1x MJX X100 quadcopter
1x 4 channel 2.4GHz transmitter
4x spare blades (2 black, 2 orange)
1x USB charger
1x 3.7V Lipo battery

Documentation (in Chinese): 1 x Manual
1 x Warranty card (valid only in China)


The Transmitter

When I first saw the pictures of the X100's transmitter, I really didn't think much of it. It seemed like just another toy TX... but when I tried it out, I found many unexpected features!
The most interesting of all was the ability to switch between mode 1, 2, 3 and 4. There are these tabs on the sides of the sticks that will switch the function of the sticks (from throttle to elevator)...and a “Aile/Rudd” button below that will switch aileron with rudder. (don't know if that makes sense. Tell me if it doesn't :P)

Another function that I like is it's equivalent of the Ladybird's 6 axis mode (NORM/PRO button switched to NORM)... basically you won't be able to flip the quad no matter how hard you work the elevator sticks... whereas on PRO mode, the quad will flip when push the aileron/elevator stick to full. (Will elaborate in the flight section).

Flight
I've expected the X100 to be a good flyer since it was first announced, so I had a lot of anticipation as I plugged in the battery. Binding took a bit longer than expected..but it wasn't unacceptable. After I flew it out of ground effect and started to hover it around eye level, the quad was almost stationary with only throttle input. I first flew around in NORM mode and it seemed to have a little more momentum than the QR Ladybird (It IS bigger and heavier, so that is expected). It's not a bad thing, just something to get used to. The 3 axis gyro+ 3 axis accelerometer combination really does a fantastic job of keeping the quad steady. In PRO mode, the quad flies almost as stable as it does in 6 axis mode. If you want to flip, give it full aileron or elevator (or press the function key). If you flip during ascent, the flip will look instantaneous and composed. Flip from level flight and the X100 will lose a decent bit of altitude...so like I said before, planning ahead is the name of the game.

It's got plenty of power throughout the flight (8 minutes or so for me) and the low voltage cutoff will kick in if you push the flight time... so try to have plenty of batteries available instead of flying one til' it quits. It might catch you by surprise.
If you are thinking about flying outdoors, I recommend that you wait until the wind dies down. The 6 axis system tries to compensate for the quad's movements that are caused by the wind. This really annoys me as it tries to take control constantly...so it's not really that pleasant to fly outside (in my opinion).
Landings are very easy as with most quads. The blades keep turning for a bit longer though so landing on your hand may not be as great of an idea as it is with other quads of it's size.

(This photo was taken with my iPad in one hand and TX in the other...if THAT won't convince you it's stable...nothing will!)

Night flight
There are 4 LEDs in total mounted on all 4 motor units. The ones on the front arms flash between blue and red while the LEDs on the rear arms are constantly white (even though they look blue in the photos).
Night flying takes a bit of getting used to if you haven't flown at night before. It's all about orientation and stick memory. Don't rely completely on your eyes... try to remember where the quad is heading at all times. You will increase the probability of regaining control of the quad if you lose eye contact with it.
I will upload a video of the X100 flying at night soon. Orientating with these lights is not hard, but it does take some getting used to, as all of my night flying aircraft have standard navigation lights... that said...after a bit of practice, I felt no difficulty flying it far away and at altitude.


Verdict

The X100 is definitely one of the best quads of it's price range. It is ridiculously stable and is a great tool for the beginners and the experienced alike. The transmitter's ability to switch from mode to mode means that anyone would be able to fly this quad.
Things I don't really like include: The dual rates switch and the function (flip) button are located in an awkward position and are hard to reach if you are operating the quad, and I think the throttle limiter is of little use. The binding could be a little quicker..but I think that's just me being picky.
All in all, I love it! It's more than what I expected...in durability, build quality and performance.

The aliens have landed indeed!

You can find the X100 at www.banggood.com's quadcopter section.

Pros & Cons

Pros
+ Sturdy structure
+ Ridiculously stable
+ Motors do not bind like the Ladybird's.
+ Walkera battery plug
+LED lights

Cons
- Slow binding
- Hard to reach function keys during flight
- Motors take a while to spin down (may be dangerous)
- No LCD screen on transmitter

With this review I would like to introduce a standardized system in which future micro quadcopters could be measured against. It is not completely objective, but I hope it's one step in a right direction towards an unbiased look at the new aircraft.
