1 × Sacrificial RC controller
1 × Small form factor Arduino I am using my "breadboardable" Arduino clone. Link in build instructions
1 × Arduino Fio For the heart of the receiver.
1 × LCD HD44780 compatible for simplicity
1 × Encoder For menu driving
1 × Battery Anything you like, as long as it outputs 5V or can power the 5V regulator on the Arduino
1 × Battery management system For boosting/bucking the battery voltage to 5V
2 × XBees Whichever flavor you like. I happen to be using a Series 2. One for TX and one for RX.
1 × XBee management system I am using Adafruit's xbee adapter. It takes care of level shifting the 5V and powering the XBee
1 × Voltage/Current Sensor For sensing the receiver systems status. I used an Attopilot
1 × Bunch of wire I just cut apart an old floppy disk ribbon cable
1 × Pile of 3/4" stand-offs Used to mount your components
1 × Pile of 4-40 screws For your 3/4" stand-offs
