I just released this video and my python library for connecting with Ardupilot Plane. As you will see there is nothing fancy, just a bit of renaming and a couple of handy functions for overriding the channels, changing modes, arming and taking off and setting the ground course.
I have never had the chance of playing with planes much, but I tell you: they are a lot of fun, especially with the amazing Plane firmware. You really have to want to crash when the autopilot is engaged!
(I took the picture from ardupilot website, I hope you would forgive me, mine were terrible)
