Nine: I didn't think of using the I/O available from FG, I'll have to look into using them.

Jon: I'm walking into the project last minute, basically, so I don't know how the autopilot was designed. I'll have to make a note to ask for their design notes.

Jeff: This is how I wanted to proceed. However, I don't have the experience at this point, and I don't have access to the uav hardware during the summer.

Curt: Thanks, if anything, I might be able to use FG to create visualizations for the project. I haven't confirmed it, but I think the project has realtime data transmision. If it does, then I don't see any reason why we can't have a real time visualization. To bad I don't have access to any test flights they do.
