    Higher MP is better.
    What engine do those 8.5 pistons usually go in? (the reason for my rod length question)
    There are several apps the dragstrip guys use that would work for us.

      Jim I posted under the current Catto thread on SC.org some reference to our conversations above and wondered aloud about using the acceleration output you suggested to examine power and performance. If interested have a look at Catto update.and??. There seems to be convincing butt fed data that promotes that product over Borer props and others. Maybe it's time for a real test. It's above my pay grade but I can run the wife's I-Phone next time I fly and see what it captures.

        "and see what it captures"

        That would be great.

          I tried it in my car today. The 3pt. pos or neg acceleration data generated depends on the orientation of the I-Phone relative to the direction of travel:

          Sampling frequency or refresh rate is variable from 1-30 Hz to allow for a choice of smoothing or fine data capture. Min and Max G is logged and the data is exportable.

            Yes, on all three axes.
