"A df log would be nice. If I were to speculate, total power failure and the FC still worked for a while. Was the impact seen in the accel data just before the end or did it just stop?  There are things to look for. I have looked at quite a few…"

Hi there Greg,

Yes, I'm still working on the camera stuff, but not as mutch as I would like.

The most recent version of the code is in the APM_Camera git branch.

It contains libraries to control the mount (AP_mount) and the camera (AP_Camera)

There is also some documentation on the wiki.

It would be nice to join efforts.

Hey  Greg ! It hit me while I was sleeping tonight and woke me up ! Getting baby scale is an Excellent idea! not just to weigh the plane but if I get one that shows ounces and fraction of ounces I can weigh each item and figure it's moment before I put it in the plane and help figure the best spot for it from the COG + or - and keep the trimming ballast to a minimum. the rest of the plane will be foam  I have been looking at power plants and might do Something Novel ? I am aiming for  a take off weight of 4 1/2 to 5 pounds  if I get a power plant out of something 7 to 10 pounds it should be lots  Thanks! Have a Great Day!

Hi Greg,

I read your posts that you have made a camera gimbal stabilizer. I work on Arduplane source code, with the APM-1 board, attaching 2 servo to work out solution for 2-axis stabilizer. It will be helpful if you could share your source so that I can have a look at it to get a better idea !
