I've been working no my autopilot for a while. The idea is to create a unit that serves as stabilization (with thermophiles) and servo-controller. Input for this unit is the roll and pitch angle (right now using rc-transmitter). Input could also come from uart, so a wireless digital transmitter or another microcontroller (with gps connected) can steer it.
The whole thing runs on a PIC16F877 and was packed into only 2k code :-)
