You may have heard about FPV racing. This new hobby where little drones, remotely controlled using video camera live stream, are challenging at very high speed and low altitude.
As I already had most of the parts with my other drones, I have decided to build a cheap “quad racer”.
Various pilots’ teams are proposing very high quality frames with a very nice configuration.
However, before to break into my piggy bank, I have preferrred to create my own configuration for a much lower price (without cutting down the performances).
We targetted for this machine a maximum weight of 500 grs.
After much thought I decided to select the quad racer GE260 frame, you’ll find herunder for approx 30 Euros:
- Integrated support for anti-vibration camera.
- « clean & dirty »system to isolate the vibrations of the motor’s arms from the rest of the frame.
First flight this afternoon, no vibration on the video and the flight controller behave correctly. Nothing to say.
For the motors I have been inspired by configurations I have found on rcgroups and I have selected 4 DYS BE1806 – 2300kv motors which are able to develop a maximum upward thrust of almost 500grs each !
For the flight controller I purchased a Flip 32 wich is an upgraded version of the famous Naze32.
I couldn’t also resit to purchase a high performance led band from Hobbyking (the same as the one utilized by the Argonay team to give the StarWars look to their machines on their videos).
I have selected the yellow ones: LED 5w yellow band 120mm x 10mm.
They are also available in red, blue, green and white.
As I already have the equipment I have then simply purchased a new transmitter which is compatible with my actual equipment.
I really recommand you the Eachine FPV200 kit. You get a tiny 200mw 32 channels video transmitter and a 700TVL CCD wide angle camera for US$30 !!! I fly with this kit for more than 6 mounth now and I’m really happy with it.
For video reception I bought a diversity receiver wich is really great to get a clear image and longer range. I use it with a cloverleaf antenna and 5 turn helix antenna.
But you can also start with a cheaper 32 channel receiver like this one :
Do not forget to also buy cloverleaf antennas like these ones: FPV Factory cloverleaf TX RX antennas.

I have placed several orders, they have been delivered in 9 days for the most fastest one and in 22 days for the longest one.
- Frame quad racer GE260 US$ 36.99
- 4 motors DYS BE1806 – 2300kv US$ 37.80
- 4 ESC EMAX SimonK series 12A US$ 32.92
- Propellers Gemfan 5*3 US$ 11 (as I am prudent,I have taken 5 packs)
- Caméra 720p 808 #16 US$ 41.99
- Eachine FPV200 US$ 30
- Flight controller Flip 32 US$ 24
- Power distribution board US$ 4.19
Total : ~ US$ 220 (battery and radio receiver not included) isn’t it nice ???
For thoses who needs to buy battery, charger and radio I would recommand :
Other usefull accessories :
- Lipo alarm 2S-4S (monitor your battery voltage/remaining capacity)
- Servo cable
- Servo extention cable (could be usefull)
- Heatsink (protect connexions)
- Banana plugs
- Power distribution board
- XT60 or T-Plug power connectors
EDIT 09/11/2014 :
I have received the leds’band ^^ :
I would also strongly recommend that you get hold of a bluetooth unit as this one. You will then be able to use an application on your smartphone and connect yourself to the drone by means of the bluetooth to perform the configuration adjustements ( this being essential on the field).I use Multiwii EZ-GUI on my Android smartphone.
Here is a basic schema to help you wire your quadcopter :
