Hi everyone ! I'm new in this forum and this is my first discussion.
I recently bought a kit for the exacter (similar to the f550).
In this days i received some different pieces, after wiring the different components, i had the problem.
I can't understand if the flight chip arrive already programmed or it still needs a flash, because the only thing that does is a looping bip coming from the ESCs.
Does the motherboard needs to be programmed? If yes, why? I tried to follow some tutorial but on windows nor on mac the chip is not recognized.
This is the url of the kit i bought. F05114 C HexaCopter ARF Drone F550 Hex Rotor FlameWheel Kit + KK 2.3 Flight Controller ESC Motor Propeller + Freeship-in Remote Control Toys from Toys & Hobbies on Aliexpress.com | Alibaba Group
I hope you can help me because i'm a newbie in this argument. 
I thanks everyone who's gonna help me.
Federico
