Now I am going to bed
Edit: The roll and pitch gyros is to be glued with hot glue onto the PCB with the silver box facing down. The Yaw gyro can be mounted like intended, the silver box facing the edge of the PCB and the connections facing up. It also can be mounted with the connections facing down, but then the silver box should face the center of the PCB. Also it needs to be reversed. Make sure the wires it not to short and stiff, or else they may break. That is the reason I placed it with the connections facing up.
