We worked on this a couple of years ago -

but I am not up-to-date on the funpilot, though I assume it is the ARM7-based controller they had under development.

The main thing to sort out is the communications between the controlling processor and the x3d. ASCTEC provided a 9600 baud serial interface and a control protocol that we used for basic vehicle control. Once you have the movement control, it's not difficult to compute GPS waypoints and feed all of that into a control loop. The main issue we encountered was that the x3d was less stable than we expected - it was unable to hold position without external guidance, and that was ultimately why we abandoned the project and moved to blimps.

I loaned my X3D to someone a few years ago and never got it back (that was a bad deal !).
