Xbee with arduino

Picture this: quadcopter with altitude sensor feeding into xbee pro....sending data to xbee on ground connecred to arduino.
Arduino generating an PWM signal to control the transmitter which sends prop speed to hold the altitude.

All from the ground without operator intervention.

Possible?

Hi,
How about all the hardware/software being in the copter, no rf link required.
I think you need to "google" how an autonomous quad copter works and/or find a quadcopter forum.

Thanks.. Tom.. :slight_smile:
