TEST: MJX X900

null

INTRODUCTION

MJX introduces here the first nanohexacopter in the market, the X900. The X900 is the little little brother of two other hexacopters, the minihexacopter [URL=”http://www.rcgroups.com/forums/showthread.php?t=2434481″]X600[/URL] and the microhexacopter X800.

BOX CONTENT

null

+ 1 x MJX X900 (with a 1S 100mAh LiPo )
+ 1 x Transmitter (using 2xAAA batteries not included)
+ 1 x USB charger cable
+ 6 x Spare props (3 CW, 3 CCW)
+ 1 x Instruction manual (english)

OVERVIEW

The X900 is just a little bit larger than a classic nanoquadcopter, for example compared with the V676

null

or with its little big brother, i.e. the X800

null

No prop guards are included. Probably because the weight is relatively already important, close to 22g so approximatively 8-10g more than the CX-10 for example.

null

Props are identical in size than the cheerson CX-10 model

null

Disassembling

8 screws to remove to split in 2 parts the canopy. The PCB is jailed between both parts

null

We can see the new popular XN297 2.4G RF chip sending the Beken 2423 to retirement.

LiPo

A 100mAh model directly soldered to the FC

null

No discharge rate mentioned but I find the battery a little bit weak. Probably a better LiPo should give more punch to this model.

Motors

Motors are 6mmx12mm coreless …

null

Transmitter

A nanoTX model ultra simple. Only 4 trims button and the left shoulder button selecting one of the three speed mode !!! that’s all.

null

Well a click on the right stick activates also 360 flip. No headless mode.The gyroscopes calibration is done by pushing both sticks in lower right position. With the X800, you can turn on/off the light.

The interior part of the design is well designed, especially the RF connexion. In practice, the control range is pretty good for a nano. We can see the PQ297 a variant of XN297. I am looking for the pinout of this PQ297 model

FIRST USAGE

The beginner mode offers an extremely slow yaw rate and paradoxaly too slow to feel confident in narrow places. Everything is good as soon as you engage intermediate mode. The pitch rate permits to have fast mouvements but not strong enough to offer great FF outdoors.The CX-10 is faster in comparaison. The plateform is stable, LEDs nice. Props pops out very easily especially after a crash.

CONCLUSIONS

Nice design for this nano-hexacopter and general good assembling quality. Very stable, this X900 is more adapted for beginners practicing indoors. The control range is good as well as the flying duration. Whatever, due to the 22g, the X900 lacks bit of vertical thrust. it’s not a model on steroids. Probably a 100mAh with a better discharge rate should solve this behaviour.

UNBOXING

PROS

+ Nanohexacopter
+ Stable
+ Design, quality built
+ Good flying duration (5min)
+ LVC LEDs alarm (after approx 5mm of flight)
+ Good radio range
+ Radio compatible with the X600 or the X800

CONS

– NanoTX format
– Props pop out easily
– Slow yaw rate in beginner mode
– No Prop guard
– Not fast in sport mode
– Automatic flips in expert mode
– No Headless mode
– YAP (Yet Another Protocol but potentially Deviatizable)

This hexacopter have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thanks them for this attitude.

You can find it actually for 22.5 USD at http://www.banggood.com/MJX-X900-X-900-2_4G-6-Axis-3D-Roll-RC-Quadcopter-p-972722.html
