Hi,

I recently bought my crazyflie, I follow the assembly correctly alterning the cables and later putting a clockwise propeller and a counterclockwise propeller, but when start to fly it start spinning out of control and turn upside down.

You need to swap the propellers. The ones marked 'A' should be on M2/M4.

Atomicdog, I swapped the propellers, and the crazyflie keeps in the floor, so I changed back, you're right, the ones marked 'A' is on M2/M4, but is already correctly as in the video. Maybe a defect with my product?

When you have connected to the Crazyflie in the cfclient are the Roll, Pitch, Yaw values stable when the CF is stationary? If they are then it is probably something with the setup.
Check that all motors are spinning in the correct direction during power on and also that the propellers are mounted correctly. I have seen one case where a motor has been manufactured with the black and white wires swapped making one of the motors spin in the wrong direction.

I discovered the problem, At each wing there's the correct motor, M1/M2/M3/M4, and I changed the motors when I assembly. I'll not rename as SOLVED, because I'll fix the quadcopter first.
