Cube Orange plus no motor and servo outputs

Hi there,
I’m normally working with cube orange and yellow. This time I could anly buy new cube ornage plus sets.
I programmed it with Arducopter 4.3.3. I couldn’t get no motor or servo output.
I tried BEC on Servo-rail and looked to all hints on the net.
ESCs are calibrated and work with normal ppm input.
Safety options are off. Safety Bitmask is also correct.
Has anyone an idea what this can be ?

Thanks for your help
