MultiWii

Hi,

I really need some help with my Quadcopter, first build.
As you can see in the 2 videos below, the copter is really not stable, making it FLIP directly when take off.
I can see even before leaving the ground that motors spins doesn't seams equal at all, and it directly flip.




Can't do anything to control it, even moving and adjusting the sticks not working.

As i begin, i don't understand everything, but i think it can b problem with the PID?

Here is my configuration:
*Firmware: multiwii 2.4
*crius aio pro v2
*4 DJI 920kv (2212)
*Power distribution board
*4 SimonK ESc
*GPS
*Battery : 2S
*Tunigy 9x + receiver
* Bluetooth Module

Any help or suggestion is welcome

Thanks a lot

Check motor connections, it looks like they are exchanged

Did you calibrate the ESC's?
Did you check motor direction spinning is correct?
Did you check the propellortype (blade) on left or right turning motors?
