TEST: HUAJUN W609

null

INTRODUCTION

Here is my mini-review of the W609-10, a micro-hexacopter equiped of 2Mpx camera. It’s one of the first camera hexacopter plateform and thanks to its 6 motors, the W609 should offer more stable videos. Let’s analyse this new “alien”

BOX CONTENT

null

+ 1 x HUAJUN W609-10 (with a 1S 650mAh LiPo ending with JST connector )
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x USB microSD reader
+ 1 x 4Gb microSD
+ 1 x USB charger for the quadricopter LiPo
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x Instruction manual (English/Chinese)
+ 1 x Screwdriver

OVERVIEW

rear view

top view

The ground clearance is around 9cm thanks to these long legs

The camera is connected via a 3 pins mini-JST connector. Good news, there is power switch

null

Some nice and bright LEDs (white on front and green on rear) give to W609 excellent night capacities

The battery bay must be opened by first turning the lock clockwise then too slide the battery door up

null

The bay don’t have a lot of room. Anyway some 750mAh turnigy LiPo seems compatible

The shipped LiPo have a 650mAh capacity, no discharge rate indicated. I found this one a little bit weak…. probably with a low discharge rate value.

and with the LiPo. The total weight reach 160g … a little bit heavy IMHO even for an hexacopter especially with some 7mm motors

oil bushing are 2.5mm(ID)x5mm(OD)x2mm(witdth)

Disassembling

null

As you can see, arms are jailed into a transparent plastic holer. It means in the absolute, you can remove the canopy structure to save close to 20g. If you remove also motor pod canopy, at least 10 extra grams can be saved. The flying duration should increased a lot in such conditions.

Some 5mm metallic boon

Some weight would have been saved with some carbon models

Flight controller

Some small ball are absorbing transmitted motor’s vibration

null

The classic invensense 6050C for the 6-axis stabilization and a XN297 for the RF part. Good news, the emulation of the XN297 by a nRF24L01 is almost complete. We can hope a deviationTX hacking for this quad.

Camera

The lens orientation can be tuned …. a good point

This camera for a toy model is pretty good. High frame rate, sharp and color respected. Unfortunatly, the lens mount is a M5.5 model and as far I know, there is no available widelens for this size.

null

Transmitter

null

4xAA batteries are required to feed the TX. The throttle trim is used to turn on/off lights when pressed up or to cycle between the two speed modes when pressed down. The right shoulder button turns on/off the camera recording (no photo mode) while the left shoulder button activ√Ętes the flipping move. To calibrate gyroscope, you have push both sticks in lower left position. It’s a very basic radio model, nothing special ….

FIRST USAGE

First thing, the W609 offers video jellofree out of the box even without installing any foam/sponge between camera/batery doors (to absorbe remaining vibrations). Videos are sharp and frame rate constant. The field of view can be better of course but at least, you can tune the lens orientation. Unfortunatly, with the tiny lens mount size, it will be hard to find a compatible wide lens. The quadcopter is already “touchy” in beginner mode and in expert mode, thank to the increased pitch rate, the W609 becomes much more sporty. The yaw rate is normal not slow not fast. I was not impressed by the power lift of this quad. I think the 160g even for six 7mm motors is not so favorable and/or you need to install a LiPo with a better discharge rate. Last con point, the control range also is not great: around 60-80 maximum out of the box. You can install the RX antenna vertically below the top canopy part as well as for the TX part. It should improve the radio control range.

CONCLUSIONS

Very stable and jellofree plateform out of the box. Coupled with a really good HDready camera, for less than 60 USD this W609 is one the best camera microcopter in the market. In expert mode, this copter can be very sporty and fast. I really appreciate the LEDs too. I regret the lack of power lift and the none-fantastic range control out of the box.

UNBOXING

PROS

+ Very good flyer, stable for beginner and sporty in 100% mode
+ Nice design
+ Good ground clearance
+ Night flyer
+ Good 720p camera (30fps)
+ Jellofree video plateform
+ Orientable lens
+ Power switch

CONS

– Oil bushings (2.5mmx5mmx2mm)
– [60-80m] of control range out of the box
– No headless mode
– Lack of power lift
– Flight time of 5min with the camera turned on
– Lens mount (M5.5) not comptabile with M7 lens

This quadcopter have been courtesy provided by Gearbest 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 57.7 USD at W609-10
