Watching the flying
Hi Figure Of Merit
I didn't have any luck on the data-logging aspect as the guy you pointed me at has been quite busy.
In the meantime I did find a HD camera (motocam 360) that can record up to 12 hours HD (720p 30fps) and can be factory reconfigured so that it automatically starts recording when the aircraft breakers / ignition is switched on.
Assuming we can set the camera to see the instruments and (ideally) out of the cockpit as well, we can kill two birds with one stone.
There is another thread somewhere about cameras but I didn't see this one mentioned.
