How to solder the motors on the print

[Bodata]

Hi,

I bought an assembled drone. When putting it together i fail to find any documentation about the soldering of the motors.

I have 2 motors with a red and a blue wire and i have 2 motors with a black and a white wire.

I understand 2 motors have to turn clockwise and 2 motors have to counterclockwise. I also understand these have to be diagonal so motor 1 and 3 turn the same direction and motor 2 and 4 also.

I guess red should be soldered to positive and black to negative. But it is not clear to me where to put which motor.

Is there any documentation how to solder the wires ?
