Here is a new chinese brand introducing a full RTF model with a 2-axis gimbal, 2K/4K camera broadcasting FPV signal, a 7inch FPV monitor and OSD informations. The UPair chase represents a direct competitor of the Wingsland minivet, the Cheerson CX-22 and the Phantom 3 standard.
The is a first early alpha stage of the review. Elements will be added on the fly. For instance, only some internal plarts are shown.
+ 1 x UPair chase (with a 3S 5400mAh LiPo)
+ 1 x Transmitter (using a 3S LiPo)
+ 1 x 5400mAh, 10C battery
+ 1 x Charger for the main LiPo
+ 1 x Charger for the transmitter LiPo
+ 4 x Props (2 CW, 2 CCW)
+ 1 x Transportation bag
No instruction manual out of the box, you need to download it here for example: http://imgmgr.banggood.com/images/upload/2015/11/SKU285709.7z
The Chase comes with a transportation bag (the props are located Inside the internal Pocket out of the box)
Nice initiative. You can be ready to fly in 1min
Originaly to power the quad, you need first to briefly press to central button then to repress it and hold it more than 2s. The same to turn off the Chase: i) briefly press the button then ii) hold on more thant 2s
At background of the battery bay, you can find the main gimbal + video connector
Good news, they decentralized the compass to avoid HF interferences
The linear 5.8G antenna
and the 2.4G located on the other leg
Some classic 22 type are installed as for most of 350mm machine. No real KV reference for them
Some 9450 self-tightning
Initially, the LiPo was missing in my transportation bag. I finally received it.
A 5400mAh with only 10C as discharge rate. A proprietary connector is present slightly different from the Cheerson CX-22 model.
I don’t know yet, if there is an intelligent auto-storage mode.According to the instruction, no auto-storage mode since they advice to store it with at maximum 50% of charge. So be aware of this.
You have to plug the charger connector with the logo UPair on top. I found, it not impossible to plug it in the opponent way, so it can be potentially very dangerous.
It’s nothing else than a Firefly 5S with firmware V1.0
with a 1600mAh Lipo
Actually, the camera is jailed by only side and plugged via the miniUSB connector
Dampening ball seems to work great in term of vibrations
Amazing, but there is a push button hidden beneath. You can’t access to it. Probably, it serves to reset/set level of the gimbal. How it’s possible to hide such important button ?
In practice, you need to remove the four motor’s screws, the four most inner screws of the landing gear, the four screws of the LEDs and the two small screws at the exit of the battery bay.
EDIT: full disassembling procedure
[*]first remove all 26 screws/bolts
[*]disconnect cable from the compass
[*]make sure the main board has come loose from the 4 points holding it in place
[*]disconnect the gimbal cable
[*]guide the antenna through the hole
[*]cut the little tie wrap that is holding the compass-cable along with some other wires
[*]disconnect the other end of the compas cable from the FC
Unfortunaly, you would need to desolder the motor’s lead wires on the PCB to completly split in two the UPair … What’s a pity, the maintenance is definitively not easy. The FC is isolated from transmitted vibrations with dampening balls. Good point.
The GPS module is located below the black protection, probably also compatible with Glonass system
An ATmega2560, a 8bits core associated generally with APM controller
What a suprize, there is a microUSB plug located inside !!!!
Here with the button, probably a minimOSD board
Here are the basic displayed information via the OSD
The main APM board
The GPS is located just above the FC, approxilative 2cm of distance. In practice, the fixing is very fast. Less than 2min for my first cold start and around 30s for warm start. In average, I receive a constant 12-14 satellites.
There is free plug. Maybe there is a way to add control to ajust brightness, contrast, etc…
Unfortunatly, the monitor is almost invisible with strong daylights, it deserves the presence of a sunshade. More, when the FPV connexion is lost, the screen turns to “black” (blue screen)
The 5.8G antenna is directly soldered as well as the main lead and video signal wires …. 🙁
As you can see, some connexions are directly soldered on the connector…. crap…
The 5.8G is directly soldered ….
A CC2500 RF chip for the 2.4G part like for the FrSky, Futaba protocols
There is uFL connector at least for the 2.4G antenna
A free port is available, on the top right (CH7 ?)
So in theory it should be possible to add an extra switch
with the 2K (firefly 5S)
with the 4K (firefly 6S)
+ Super stable video plateform
+ Almost 0 transmitted vibrations
+ APM based
+ Fast GPS fixing
+ Great control range
+ 4K camera version (firefly 6S)
+ Transportation bag
– No direct USB connexion to mission planner out of the box (very important to perform compass calibration, compass mot, etc…)
– No LCD settings available
– FPV monitor not visible in strong daylight conditions
– “Blue” screen (in practice a black screen)
– Some soldering job directly on connectors (transmitter, receiver)
– No gimbal settings available
– Gimbal FC housing impossible to open and potentially a source of unsoldered wires in the assembling stage
– Gimbal reset/set level button not reachable
– No all spare parts yet (should come very soon)

This quadcopter 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 550USD(2K)/600USD(4K) at http://www.banggood.com/UPair-UP-Air-FPV-With-12_0MP-1080P-SONY-HD-Camera-2-Axis-Gimbal-RC-Quadcopter-p-995265.html
-Mission planner connexion
Maybe you can do a better job, but I did like this. You need a short (10cm) microUSB to USB cable (no OTG) and USB female to USB male cable extender
You will need to attach a small microUSB to USB to attach the UPair to the APM/arducopter mission planner software
