The ECU stores the last 51 minutes of info. It should be no problem to get this information back. My dead stick happened about a week ago. I have flown the model twice since then but still got the data I needed.

Edit:

If anyone is interested in looking at a graph that can be produced, PM me and I'll e-mail a copy of the Excel spreadsheet with the graph attached. I would post a pic but don't know if I can do it.
