Mini-Review

Wingsland Scarlet Minivet (Under construction)





ALERT

The last firmware (20150805 black.vast for black PCB ) seems partially buggy and can provoke some crash (especially in L1-0 slow GPS mode). I advice to not upgrade to it or if you have it already to downgrade to the former given in the bottom of #2.






ALERT

Actually, software associated with FC & Gimbal are not yet released. It's strongly advised to wait before to purchase it until their availability (should come in june 2015)



Softwares have been released (FC & gimbal)



INTRODUCTION





Here are the first elements of the mini-review of the Wingsland Scarlet Minivet, a all-in-one 390mm brushless quadcopter equiped of a 3D gimbal, a full HD cam (30fps) and 5.8G FPV part. I will construct this mini-review step by step in order to give you as soon as possible important elements of the model.

BOX CONTENT



+ 1 x Wingsland Scarlet Minivet
+ 1 x 3S 5200mAh battery (proprietary connector)
+ 1 x Charger
+ 4 x Prop lock
+ 1 x Transmitter (10 channels using FSSS technology)
+ 1 x 2.5" FPV monitor
+ 1 x Instruction manual (english/chinese)


OVERVIEW

The general informations given by the constructor : http://www.szsungreen.com/en/index.p...t=list&tid=129

- Maximum of 3m/s
- 600m of radio control range and video range
- Camera : 4Mpx, 1080p@30fps, 720p@60fps



- Main body











- Battery connector

A proprietaty one is used, but in a first glance, it could be possible to mod this connector to welcome a more standard model




- 2.4G receiver





- Top canopy



A serie of LEDs are located on the border of the black plastic indicating the GPS reception quality.

Close to 900g without the battery and props




- Landing gear

Landing gear fixation



Rubber feet



Both the 2.4G and the 5.8G antennas are located in each foot respectively. Here, the 5.8G atenna



and the 2.4G antenna



ESC aeration holes



- Arms




Motors are 2212 model (no KV information yet). Shafts are7mm (5mm screw)




- Propeller

1045 model with 8mm shaft (w/ two flat sides). This model is for example compatible with XK X380 model.






- Prop lock

With a diameter of 5mm



- 5.8G VTX



Two micro dip switches are located to select channels. By default, the frequency is set to 5645Mhz (a Boscam freq). I will check if there are some Fatshark compatible frequencies. Notice the gimbal's micro-USD port proably to set gimbal parameters/flash new gimbal F/W.


- Battery

A 3S 5200mAh LiPo







The battery after 48h is entering automatically in auto-storage mode .... Great feature....




Disassembling

You will need a 2mm hex screwdriver to remove the 16 screws to access to the main quadcopter electronic



After a quick overview, all soldering jobs are very clean and covered with hot glue.

-ESC





-Flight Controller and PDB

I received the pre-release version. The final version have minor improvement. The pre-release version have a green PCB while the final have a black one. This is why FC firmware (.vast files) have color indication in their name






The gimbal is connector on the "P7" port. No information about the FC design. Maybe a home-made model ? Ground station software have been released (see below)






The GPS module is well protected to RF interférences



The flight controller software can be downloaded with these 3 links (installed them in the same directory)

Gimbal and camera



You can see the 2 micro dip switches to select one of the 8 frequencies



a microSD slot located beneath. Be aware, to not push the micro-SD by accident Inside the camera chassis..... It would have been much more better to add another micro-USD port to export via a cable all contents



The set camera + 3D gimbals scales around 200g



Main gimbal PCB







After removing the 4 screws behing the camera module, we can acceed to the main camera electronic

The INS sensor



and the main video MCU: a NOVATEK NT966508G



Main codec informations:



Wingsland scalert minivet first camera snapshot (0 min 45 sec)



Actually no gimbal software available in the official webpage : http://www.szsungreen.com/

minivet camera menu2 (1 min 18 sec)




Transmitter

A very nice chassis with mate plastic. A 10CH model : 2 left 3-way switches to select flight modes, 2 right switches (one 3-way, one toggle) for the camera module and joystick located behind to control the gimbal. Both sticks have springs. I didn't find yet how to turn in into mode 1 and vice and versa.

The L1 in upper position represents the manual mod while in bottom position engages the RTH. For L2, if in bottom position, you are activating the Headless mode. In upper position, you set/record a POI (Point Of Interest) (I think L1 must be also in central position).
I will investigate later about this new feature.













a CC2530 RF chip (a variant of the CC2500 used for the FrSky and Futaba protocols) is installed



If you plan to install an external antenna, you will have to solder directly for example a RG316 coaxial cable or to solder a uFL connector to welcom a uFL-RG178-RP-SMA cable for example


2.5" FPV monitor

The 2.5" FPV monitor offers on the right side ; a press button (long pressing : to turn on/off monitor, short pressing: to cycle over the 8 videos frequencies), a 1.5mm jack (probably an AVout), a micro-USB slot (to recharge the 850mAh LiPo) and a status LED (red : recharging, blue : charged)

The instruction do not mention the frequencies available via this FPV system. I collected them

FPV monitor

Channel Freq

CH1 5645Mhz
CH2 5685Mhz
CH3 5725Mhz (work also @5733Mhz)
CH4 5760Mhz(work also @5765Mhz)
CH5 5800Mhz (work also @5805Mhz)
CH6 5840Mhz (work also @5845Mhz and 5847Mhz)
CH7 5885Mhz
CH8 5925Mhz

There are some boscam band and probably some Fatshark ones ...







The 5.8G antenna seems a half-plan model



An mod would be to install a RP-SMA connector

A 850 mAh 1S LiPo







Unfortunatly, this monitor offers blue screen when the connexion is lost ....


FIRST USAGE


Here the video of my first flight with the Minivet. Unfortunatly, my gimbal is not perfectly tuned and rotate by itself. Whatever here is the results of my first flight. From 5min50, you will have toverlayed he FPV live video on bottom left and the 1080p recording on bottom right.
I used an AOMWAY RX004 to record the FPV part.

Wingsland Scarlet Minivet first (raw) outdoors test (Courtesy Banggood) (10 min 15 sec)


For a first test, I was positively impressed by the general quality of the camera especially with the HDR option turned on. Even if my gimbal is not correctly calibrated, videos are jellofree. In another hand, I was not impressed by the VRX sensitivity. Clearly, this FPV monitor need to be modded in order to install RP-SMA connector + cloverleaf antenna. The latency is around 100ms and no extra latency/frames drop is observed when recording is turned on too.

Concerning the quadcopter itself... very positives feedback: stable, GPS position hold efficient, visible LEDs,

EDIT 06/29/15

I installed the gimbal V1.01 and perform a first stability flight.

This video is not processing by any stabilization software. The result is already very good


Wingsland scarlet minivet maiden beach session (Courtesy Banggood) (8 min 17 sec)


WIth balanced prop, the results is even better

PROS

+ Stable quadcopter
+ Efficient and lightweight 3D gimbal + camera combo (~200g)
+ OSD informations
+ POI
+ Powerful 5.8G VTX (400mW sharing Boscam & Fatshark freq)
+ uFL connector the VTX antenna
+ Quality build
+ Good battery duration (~around 20min) with auto-storage feature (after 48h)
+ For 600USD, (500 with WS M499 coupon) complete and cheap 3D gimbal AP + FPV


CONS
- Too small FPV monitor
- No DVR in the FPV monitor
- Poor VRX sensitivity (but can be modded)
- Proprietary battery (but can be modded)
- No pan control of the gimbal via the joystick
- No mission planner software (yet)
- Not sporty quadcopter, it's a real AP
- FC software still uncomplete but should be updated soon
- No microUSB plug in the camera module
- MicroSD card can fall by accident into the camera support


You can find the "Green" Firwmare for pre-release model (green FC PCB) and the "Black" firmware for the final minivet version (black FC PCB)

EDIT 07/21/15

Please find the full instruction manual at: https://mon-partage.fr/f/887F0ibu/

EDIT 01/20/16

Antennas modding:

TX antenna









uFL RP-SMA replacement






Pre dril a hole with thin tweezer





enlarge current hole with drimel









RX antenna

Disassembling







Lift the black connector locker to remove the ribbon cable of the LCD










Pre-drill a hole (be aware, the hole have to be at the bottom part, if not you won't be able to reassemble)





You can see where to drill the hole (You can see my unsuccefully first attempt....)

I am afraid with the current FPV monitor, this 600m is true is pure LOS condition. A basic mod would be to install a better RX antenna and probably also a CL antenna for the TX part. I will check this point asap
