Basic Theory of Operation?

Hello everyone. I'm a newbie here and am looking to build a UAV. I've been flying R/C airplanes and helicopters for about 10yrs and am looking to make the next leap using ArduPilot on a 4 channel electric airplane. I've gone over the tutorials and newbie guides but have a few basic questions.1) Can Ardupilot stabilize the rudder or is an aditional gyro needed to help coordinate 4ch flight?2) Can Ardupilot maintain altitude and airspeed seperately or is throttle the only meens of altitude control?3) With Xbee modules set up, what hardware is required to recieve real time telemetry back from the aircraftThanks for the help and hopefully I can get my project in the air soon.

    1) ArduPilot uses either the rudder OR the ailerons to stabilize and navigate. It does not support coordinated turns at this point. (It only supports three channels out)
    2) ArduPilot uses both throttle and elevator to control altitude
    3) Just your FTDI cable and a laptop if you use the software Ground Station. Or dispense with the laptop and FTDI and use the ArduStation hardware.
