Update 15/08/15: The build instructions are finally ready. It was a lot of work to get everything together so have a look at http://www.firefly1504.com to find all info and parts you need for this build. If you have any problems don't hesitate to give me a shoutout or pm me.
You can find the build instructions on my website at
With Escs you got 2 different options. If you choose the 4in1 Esc you won't need a pdb anymore since the 4in1 esc has a bec (5V voltage regulator) to power your flight controller.
If you use the slim escs from dys you have to add a PDB to add a voltage regulator and to distribute the power to the escs. Nowadays I would recommend to take the 4in1 it makes a cleaner build, reduces costs and also ist the newer option in terms of performance and software compatibility.
This is also just an overview. These are products that I have personal experience with and which I can recommend. There are tons of other transmitter and receivers out there but these are in a reasonable price range. I am personally flying the Flysky TH9X with the Frsky XJT module and am very pleased with the overall performance.
