I was really looking for pointers on how a 'common guy' can gather this data with reasonable accuracy (and, hopefully, without investing thousands of dollars). You have clued me into using the GPS track/recording functionality. I can see how this would work quite well. While no longer a pressing issue for me, I will still explore this as I'm a bit of a data junkie. Thank you!!
While not quite as accurate as instrumentation a good flight test engineer could probably get you something reasonably accurate. They did it before orange wire and high speed data. Iíve seen some rather accurate data gathered this way.
