<DIV>Hi Earl</DIV>
<DIV> </DIV>
<DIV>Jerry and I are playing around with the Flight Data Recorder we are
using it to help with some design changes to the Silhouette lots of good
information. I was surprise to find out that my average flying speed was around
60 mph I though I was flying slow</DIV>
<DIV>I will give more information about our use later.</DIV>

<DIV>The flight data recorder works well and provides useful information.
Excel, and the ability to order the data, is necessary to make best use
if it. I feel that the altitude data are the most useful, in that
they allow assessment of how well one returns to / maintains entry altitude,
really important on things like vertical eights where the airplane passes
through the same point thrice. Speed data are also informative and, I believe,
can help one improve maneuver presentation.</DIV>
<DIV> </DIV>
<DIV>Having said that, I haven't used it as much as I would like. Getting
access to the data port through the bottom of a Hydeout isn't very convenient.
We've flown it in Andre's Smaragd and did not get consistent altitude data,
probably due to pressure variation within the fuselage. The manufacturer
provides info on how to attach a tube for exterior pressure pickup, we just
haven't done that yet. I'm building a Partner which will have a pitot tube
port in the wing LE, the exterior pressure pickup and easy access through the
canopy. All post season fall projects, along with checking the recorder
altitude / speed numbers for accuracy.</DIV>

<DIV>Jim Oddino is using one also. We have both looked at voltage after the
regulator. No surprises here, the regulator does the job. (Might be
interesting to look at volts without the regulator.) Jim has effected a change
in software to improve the range of voltage data acquisition. </DIV>
