<DIV></DIV>
<DIV><FONT face=Arial size=2>Several have mentioned the lack of help in the
form of coaches, competent observers, etc. which could help them improve
their flying skills. This is probably more common than not, and makes
it difficult for each of us to improve (even the FAI guys). I've found a
couple of ways around this that some might find useful. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The first is score analysis. Simply input raw
scores (each maneuver / each judge) into a spreadsheet. Even a 4 round
contest with 2 judges / flight will yield 8 scores / maneuver. Average each
maneuver's score set and calculate the standard deviation. This provides a
feel for how well any given maneuver was flown and a feel for consistency -
the lower the std dev the better. This info lets one see what needs
improvement the most and, over several contests, note progress.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Of course score analysis doesn't indicate just
what the problem is. There have been many good suggestions regarding seeking
that input from fellow competitors, interested observers, etc. Another
method exists that can provide valuable info.</FONT></DIV>
<DIV><FONT face=Arial size=2>That method is a datalogger. I've recently been
using the latest USB Datalogger to look at in flight parameters. <A
href="http://www.eagletreesystems.com/Plane/plane.html">http://www.eagletreesystems.com/Plane/plane.html</A>
This newest version provides a useable graphics display of flight parameters
(even more useful if the data are evaluated in a spreadsheet) - your choice
as to just what to look at. I typically log altitude, airspeed, and aileron
inputs. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The altitude inputs allow observation
of entry / exit altitudes, altitude changes in level flight, diameter
(height) of loops, cross over points, altitude loss / gain during spin
entry, altitude loss / gain during rolls, etc. All basic stuff that's
important to get right for good scores. Speed data provide clues as to
where too much / little power is used and whether a prop works well or not.
The aileron inputs can be superimposed on the altitude data to determine
roll position on vertical lines. While not all pattern parameters lend them
selves to analysis with this technology, a good deal can be learned
with it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>While recently evaluating engine /
prop combinations (very top secret), I noted something that looks useful
regarding snaps. During both up and downline snaps the speed signal drops to
zero for a period of time roughly equivalent to snap duration. It appears
that possibly airflow separation from the wing includes the pitot tube.
Upline snaps also show a marked decline in ascent rate during the
snap. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Recent snap discussions have made me curious,
so I've decided to do some snap analysis with a G-force sensor
connected to the logger. I've ordered the sensor and plan to take
a good look at "real" snaps and barrel rolls. What to bet that the G
loads spike quickly then drop dramatically during snaps, but
increase throughout the barrel rolls? I'll present this work as
a K-Factor article when finished, if anyone wants data sooner,
a datalogger costs the same as a couple of
servos.</FONT> </DIV>
