I’ve received a small, brushed quadrocopter for testing and review courtesy of Gearbest.com. You can find it on their website as Fluoreon QX80 80mm Mini RC Quadcopter Frame Kit – PNF. Contrary to what the photos of the product suggest, it’s almost ready to fly on arrival, all you have to do is install the micro-receiver & configure it in Cleanflight, set the channel on the camera/25 mW transmitter combo and you can start flying with it.
The whole kit is packed inside a sturdy box which can be used for storing the quadcopter.
This is what the complete kit looks like when unpacked.
It contains the assembled Fluoren QX80 quad
2 x 1S 600mAh batteries
Twin charging battery cable, with a 3S balancer plug on one end and two Molex 2.0 connectors on the other
4CW & 4CCW propellers
Propeller removal tool which isn’t usable, as you can’t wedge it under the prop to remove it.
Fluoreon QX80 – specification
brushed QX906 8,5x20mm motors
SPRacing F3 EVO Brushed flight controller
500TVL PAL camera with an integrated 25mW 32 channel transmitter
1S 600mAh battiers
RTF weight 60g
Configuring the quadcopter requires attaching a receiver to it, in this case it means soldering the cables to the UART2 port and then configuring the pre-installed Cleanflight software. It’s an older version, so I recommend updating to the newest version, or better yet – to swap it out for Betaflight which in my opinion makes better use of the F3 chipset features.
The receiver used should be obviously compatible with the radio controller – since I’m flying using a Futaba 14SG I used the SK FM800 receiver with short antennas which is perfectly fine for use here.
I carried out the first few flights with the factory-installed Cleanflight version in ANGLE mode. In such a setting, the quad is very easy to control, however the input responses were a bit slow. When switched to ACRO mode the copter became quite jittery and very hard to fly using the stock settings. Lowering the RATE value helped a lot and the drone was much more pleasant to fly with. Below you will find a screenshot of the settings for the ACRO mode.
Image from the video camera is quite clear and despite the video transmitter only having a declared output of 25mW there was very little issues with receiving the signal through a few walls of the house during flights.
In conclusion, the QX80 looks to be a fun toy for winter flying around the house or other small indoor locations, it’s perfect for pilots who don’t have access to a full size indoor location for their bigger quadcopters.
