TEST: Bayang X16, the brushless SYMA X8C competitor

null

INTRODUCTION

Bayangtoys delivers with the X16 their first brushless model, a 350mm machine so strong enough to carry easiy any GoPro. With the Bayang X16, they used the same 350mm chassis than the X15 but replaced all brushed motors with some strong 2204 brushless motors. Of course all electronic have been upgradated consequently with the introduction of ESC. The X16 is announced to be pretty cbeap (around 100 USD w/o shipping) so the objective here is to be a direct competitor of the SYMA X8C with a real brushless model.

BOX CONTENT

null

+ 1 x Bayang X16 (with a 3S 2200mAh LiPo with HXT 3.5mm connector)
+ 1 x Transmitter (using 6xAA batteries not included)
+ 1 x Charger
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x Screwdriver
+ 1 x Wrench prop tool
+ 1 x 720 camera
+ 1 x microSD card reader
+ 1 x 4GB microSD card
+ 1 x Instruction manual (English)

OVERVIEW

Maybe slightly inspired by some walkera’s product, at least the design is no more a new direct cloning of the Syma X8. The full body is based on relatively good plastic material, IMHO good to handle moderate crashes. It’s a first good point. Installed on top a fake GPS antenna module. Don’t expect any flight assisted mode with the X16.

-Front view

null

With landing gear, campera and prop installed

null

With the X8G camera attached

null

The camera can be clipsed perfectly and have the same 2.5mm jack plug

null

But unfortunatly, the X8G camera can’t be used with the X16 (not powered …)

With a GoPo attached

null

thanks to the H899 camera mount. With this mount, you have to aim the center of the clip system coz the H899’s bar is slightly thinner.

null

LEDs allows perfectly some night flights

-Upper view

As said previously, the GPS module is a fake decoration one

null

null

-Bottom view

On the left, a powerswitch button and the camera port in 2.5mm jack format like SYMA’s model.

null

You have also the same central clipsing system than X8. You need to press the central plastic button to release attached camera.

close to 10.4cm of ground clearance

null

probably not enough to attach a standard 2d gimbal but maybe a compact mobius gimbal can be installed beneath

null

-Weight

null

null

null

Close to 715g AWG…. it’s a lot… Definitively no more a toy for kids.

null

Props

Some standard 8inch props

null

with 5mm DJI hub style

null

Some larger model can be installed, some 9443 for example

null

1-2mm of free room from the rear canopy side… 🙂

null

It should increase payload capacity and extend a bit flight time if the LiPo and ESC can handle the extra power required.

Motors

null

null

5mm shaft

null

To disassemble each motor or to oil associated motor’s ball-bearing, you will have to remove the lower motor cap

null

Only 3 M3 hexscrews are locking each motors. Quality are poor very easy to strip so be aware.

null

I am absolutly not impressed by the motor quality. On all my first motors, you can find some residues on copper’s wire… Building seems to not be ultra perfect too.

null

LiPo

A large 3S 2200mAh LiPo with HXT 3.5mm connector (aka banana plug but be aware, real banana plug are more 4mm and with different internal connectors). No discharge rate mentioned. This LiPo should offer at least 10 min of flight time.

null

null

null

null

With the original charger, you need more than 2h (close to 3h) to charge the battery.
I strongly advise to build your own HXT 3.5mm cable to use a more prefessional charger. You need to find such connector: http://www.ebay.fr/itm/Ladeadapter-Ladekabel-3-5mm-HXT-Buchse-auf-T-Plug-Dean-Stecker-/121356935857?hash=item1c416fe2b1:g:t4sAAMXQpPhTkEHR
but beaware you will need to invert the GND & VCC wires on the Tdean connector to have the right polarity’s connexions

Camera module

The shape is excactly the same than the SYMA X8C module. The lens is unfortunatly a forever pinhole model with a narrow Field Of View (70 degrees approx).

null

The clipsing system is nothing else than the X8’s copy.

null

null

Unfortunatly, performances are very similar very disapointing: not 30fps but more around 15fps, poor light sensitivity, not precize, etc…
To make short, a very poor camera. Here is a raw video sample

Disassembling

You will need first to remove all the 8 screws associated with the landing gear then 8 extra screws for each lower motor cap. Then 4×6+4 screws so a total of 44 screws… to remove to access to the X16’s interior.

null

null

First bad surprize, a cutted wire … between a motor to the ESC

null

Second bad one, another wire directly disoldered from another ESC

null

Finally, ESC’s PWM signal wires are directly soldered on these servo plug pins…

null

Crap… I strongly advise to spread some liquid electrical tape at least on these connexions.

The main FC board welcomes a L883 compass chip for the headless & one key return functions. It means you have headless with “homelock” (reference is set at take off or when resetting headless reference by pushing both sticks in lower left positions).
The 6-axis stabilization job is done by the classic MPU invensense 6050C. The RF chip is a XN297L, an upgraded version from the XN297. This new revision offer a new datarate (not used here) and better RX sensitivity too. The range should be a little bit improved versus the original XN297. Good news, the radio protocol is the same than for former X8/X9 Bayang model… Thunb up for this !!!. It means, you can fly the X16 with a compatible DeviationTX radios modded with a nRF24L01 RFchip.

null

As far I saw, no barometer chip installed so … the altitude hold advertized feature can’t be here….

ESC

Individual ESC for each motor. It’s a good new in case of failure.

null

null

No reference for them… There are some pads for an eventual firmare update.

null

Transmitter

A large transmitter chassis with a mini black & white LCD display.

null

Two shoulder buttons, 5 other ones in circling layout to the right and 4 vertically aligned ones to the left (not assigned). The left shoulder button cycles between the two speed modes. In practice, these two modes are well tuned IMHO. The beginner is ultra stable to shoot as smooth as possible videos while the expert transform the X16 into a much faster machine. The right shoulder button don’t do anything AFIU… (a residue of the X15 model where the flip were engaged via this button).
The 5 right butons permit to trigger the camera for photo (up) and videos(down), to engage the headless mode (right) or the pseudo RTH (central). The left one emits either one beep or two beeps but don’t do something special.
Very important, especially before each take off, but to calibrate gyros, you have to push both sticks in lower-right positions. To set the headless home course, push both sticks in lower right. Finally to arm/disarm the machine, push the sticks in lower outter directions.

6xAA to feed this transmitter.

null

null

null

The RFchip daughter board welcomes a PA part. A good sign for long range control.

null

FIRST USAGE

First of all, at least with the model I received, I noticed sometimes, one motor start to spin at full speed like depicted in this video

It seems that gyros loose very fast their calibration and need to be recalibrated before each flight by pushing both stick in lower-right position.

Second point, maybe linked with one potential bad motor, but I oberved some crashes linked with a blocked motor like you can see here:

After cleaning it well, added some drop of sillicone oĂŻl on ball-bearings… This problem seems to be solved (I hope too).

Here is a first small demo… For sure the X16 is very powerful thanks to its brushless motorization… I really appreciate they keep the same radio protocol and by consequence the DeviationTX comptability.

As you can see here; pumps are not bad at all for a 715g machine

Finally, a more complete testing with the original camera.

As expected result with the original camera are very poor and full of Jello…. so clearly unsatisfying. Props are really unbalanced and need to ajusted to remove some Jellos. Anyway, the X16 is super stable and nible… Not ultra fast even in sport mode… it’s not a racer but a AP machine. In expert mode, with the original radio, I found rolls mouvements jerky while when controlled with my Devo7E, it’s much smoother… The machine handles Wind superbly…a very good point. The control range is really good (tested over 150-200m without problem) and the flight time in average around 11min. With better and larger props, a better vibration isolations, I am pretty sure than videos can be Jellofree with the X16.

CONCLUSIONS

A potential SYMA X8 killer if and only if two conditions are fulfilled: i) general electronic quality build must be improved and ii) the price must be below 120USD IMHO (with shipping). If above 120… the question will be transformed into “why not take a cheap Cheerson CX-20/FLying3D X8 instead ?” offering GPS assisted flight modes, a gimbal port, etc… for around 200 USD. Anyway, is the Bayang X16 a good flyer ? The answer is definiively yes… This machine got a lot of power, can carry easily a GoPro or eventually a 150g gimbal+mobius cam system… The control range is really acceptable out of the box and thanks to some antenna mods and/or deviationTX support can be even improved. Flight time are also compatiblewith what we are expected with a video plateform. Be aware, with 750g, this machine must be handled safetly and since no prop guards far from any kids.

    Oui fois ouvert, cela craint vraiment… 🙁

  • Steve says:

    I really appreciate your review. I just received mine yesterday and the first thing I did was take it apart and inspect everything. I found a motor mounting screw laying in the bottom of the quad. All of the solder joints looked good. I screwed the motor mount back in and put it back together. Then I set it up and went through all of the calibrations. I then armed the motors and one of the front motors started to smoke badly. I don’t know if I want to send it back. It took a long time to get. Have you found any replacement motors?

  • Tom Acklin says:

    I just got the X-15 updated drone with no manual in the box, only a QR code for something in Chinese. No English!!’
    How can I download a manual in English?

  • tom acklin says:

    Does anyone know if the X16 manual is similar enough to assemble and operate the X15 Bayang quadcopter?

    Where can I find an English version of the X16 to download?

    Thanks,

  • Carlos Galanducho says:

    Hi, how many meters does the Wi-Fi antenna get from the camera? (To connect with the phone and to pass image)

  • John Nutt says:

    I bought the Bayang x16 upgraded version when I tested it I took it up about 3 meters and the altitude hold worked well so I took it up about 20 meters and it took off at top speed all on its own and would not respond at all so I shut the controller off and it kept going out of sight I have never found it. I purchased it from Hobbywow and they will not respond at all. There is absolutely no way to contact Bayangtoys. This is a defective product and a total waste of money.

    • SeByDocKy says:

      Did you purchase the GPS version ?

      • John Nutt says:

        No I did’nt but it was supposed to have gps capabilites. The online store that i bought it from does’nt offer that model and im thing it was a big mistake ordering from them. I will never order anything from HOBBYWOW again they still haven’t responded its been 2 weeks now since i requested some kind of contact.

        • SeByDocKy says:

          I am afraid the compass calibration was done correctly and with some GPS machine, your can have such ingredible flyaways 🙁 ….. and with such cheap GPS model… was very predictable. For Hobbywon, I would say like most chinese website, no Customer service at all 🙁 ….. After, it’s chinese events now … so since 10 days china is off …. should resume now

  • phrancis5 says:

    Nice review! Do you know if the TX can switch to mode4 flying by holding a trim button and turning it on, like the Syma X8, that it appears to be cloned from? Maybe the gimbal sticks have wires to the control board that can be switched? By mode4 I mean throttle/aileron on the left stick and rudder/elevator on the right. Thanks.

    • SeByDocKy says:

      I have no idea sorry 🙁 ….but I think with a bit of soldering job everything is possible… If you have a Devo controller, the Bayang X16 is hacked for it
