As far as I remember, this was an ugly hack of the Hex+ configuration. Two motor outputs are removed (front and rear) are not used if armed but unarmed. They control the driving speed and the servo for the steering if unarmed.

If the serial port on the NanoWii is not used, you can connect a Bluetooth adapter to this. Googling for NanoWii and Bluetooth will give you some results.

Use MultiWiiConf or WinGui or whatever you have to look at the running flight controller.

I would bet your sticks are not calibrated to 1000-1500-2000. I think throttle will be around 1150 too in low position. Then MW will not arm. Trim your enpoints to match 1000 in low, 1500 in mid and 2000 in high position as close as possible.

Re: brushless motor rotation is not the same
Just swap two wires between ESC and the motor. This will make the motor rotate in the opposite direction.
But remember that your quad needs two motors rotating clock wise and two counter clock wise! Details with pictures can be found on the multiwii website.

As Kbev5709 already said: adjust your channel ranges in your transmitter!
The different values for the motors make sense as the copter wants to yaw right (1522).

You will need a free serial port (UART) for this. Then connect TX to RX and vice versa. You will also need to set the GPS and MultiWii to the same baud rate.
