Hey Fredrik,
There should not be any configuration of UART's needed; the pypilot should talk to the motor controller out of the box. On the arduino there should be 2 LEDs flickering: one for received data, one for transmitted data. If there is no LED activity seen, check electrical connections.
Now there is one thing that seems to be nowhere explicitly mentioned: you should connect TxD of the Pi to RxD of the arduino, and vice versa. Crosswise, so to speak. For some this might sound weird, for others this knowledge was spoonfed to them as a baby. Just tell me you did it this way and what the leds do.
Cheers,
