£200 autopilot
 

I was wandering the interweb thing and found this -ArduPilot - DIY Drones
It costs $250 and can control an amateur built UAV around 100s of waypoints and then land. I wonder how much it would cost to connect it to a Warrior?

That's designed to control servos on a model aircraft, so the you would have to work out a way for it to power the control surfaces in a way that can always and easily be over-ridden by the pilot. I would imagine the cost of making it actually work would be very reasonable. The cost of getting it past the CAA would be HUGE, and unless you wanted to try a business selling them it would undoubtedly be cheaper to buy one off the shelf.
