Big day of ArduPilot and BlimpDuino work at DIY Drones HQ (my house in Berkeley). Jordi and his wife are up from LA and we've been debugging code and tweaking PID loops all day. We also set up a second simulation environment. It was a beautiful day today but we didn't get out to fly. Too many bugs to work out. Maybe tomorrow.

Nice work! Jordi and you are going to deserve an award for all this amazing work!

Is the second simulation environment different from the first? I was wondering why the free FMS simulator wasn't chosen?

Looks like you guys are having tons of fun :)
Unfortunately I am not sure that Sunday will be good day for flying...at least it's raining where I am (Pacifica) : (

We used X-plane because it is shipped ready to output the attitude data that we need. We don't know a good way to with FlightGear without modifying the source code, and FMS doesn't output that data at all. Xplane is also really good, with great scenery etc. I know FlightGear can probably do this in some easier way than we found, but we're not expert enough in it to know yet...

FlightGear (1.9) provides the attitude data and they are accessed via:
Pitch: /orientation/pitch-deg
Roll: /orientation/roll-deg
Yaw: /orientation/heading-deg

I used pitch and roll in my UAVsim example that is described in the UAV Playground blog post.
