Unmanned Aerial Vehicle:  Multiplex Twinstar
Armed with the valuable experience I've gained flying my Wingo autonomously, I decided to move my autopilot equipment to a more suitable airframe.  I selected the Multiplex Twinstar because of it's size, composition, power system, and payload capability.   This page will describe the details of my installation.
Before we begin
While the idea of autonomous flight is very exciting, it entails some risks.   The additional equipment raises the level of complexity of the airborne equipment, and consequently adds to the number of things that can go wrong.  Anyone considering this should fully understand the risks, and never, ever, fly over populated areas.
The equipment
The only visible portions of the autopilot are the wing lever's sensor module, and the GPS receiver.  I was able to bury the rest of the components inside the plane.  The GPS receiver has been hacked down to the lightest possible form factor.  A custom built 3.3v regulator powers the unit from a li-poly battery pack inside the plane.  The serial output of the receiver is fed to the unav PDC10 autopilot unit, which steers the plane by the rudder.  The FMA copilot keeps the wings level as the PDC10 tries to turn the plane.  This results in a very smooth, gradual turn.
Here you can see my equipment layout. The FMA Copilot processor unit shares a space with my RC receiver.  The foam in the battery compartment was routed out with a Dremel to make room for the PDC10 near the front of the plane.  This is attached to the GPS receiver via a long cable that carries power to the GPS unit, and serial data back to the PDC10.
