<DIV><FONT face=Arial size=2>Hey David,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If the model gives the cone you describe...then
it broke in pitch! If the model doesn't show the cone then it didn't
break in pitch. Just a note that if it cones it also departed the path in yaw
as well. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I agree with you 1000000000% if its not a barrel,
and its not a axial roll this its a snap...we all know what the barrel looks
like...and we all know what the axial roll looks like...The snap is the only
other rotation thing the model can do in the roll axis.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This is pretty easy to see if you think about it
this way...The only way it can show the CONE is if it had a BREAK or departure
(a break in pitch). If it never broke then it will not show the
cone!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Speed of rotation is very very dependant on lots
of factors. More rudder will cause the snap to be more violent and as a result
it can rotate very fast. More aileron will cause the snap to be tighter and
still have a higher rotation rate. More elevator will cause the model to start
the cone quicker. Not enough elevator and the typical scene is the model
stalls but only after about a 1/8-1/4 rotation. This can be seen in the snap
that winds up...where it rotates slowly then gets lightning fast when the wing
finally departs. This is usually a very unpredictable exit with the pilot
missing most of them.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Another note is a snap that describes a cone and
stays online is actually a more pure break or a better break...but sometimes
the snap police or SNAP Nazi will zero this snap. The reason is the model
stalls quicker and pitches first meaning the model doesn't jump left or
right....The ones that jump over are not quite stalled when the rudder and or
aileron is applied. If it stalls quickly like the rule book sometimes it
harder to see the stall...or the pitch but you can see its effects in the CONE
for sure. The only way it can cone is if it broke....No cone no
break!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Another note to the pilot flying it. The snaps
are easiest to do at the slowest possible speed. Reason it takes less pitch or
elevator to get the wing to stall right away. This makes them stay on heading
better...The bench mark is do you have enough energy after the snap to keep
flying or is the model wallowing and falling out of the sky...or is it coming
in fast and the rotations are quick and the snaps are extremely violent...then
you might have too much speed or energy.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> Judging Snaps</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I have always judged snaps with a simple rule
-- if it is not a barrel role, and if the tail describes a helix or cone,
then the plane must be stalled, and therefore it is a snap. I have
never downgraded because the plane is set up with a lot of aileron, so long
as the tail wags, and so long as the nose and tail describe opposing
helixes. I don't see any reference to how fast or slow the plane rolls
with regard to downgrades. To me, a pilot is free (and smart) to set
up their plane such that it loses as little heading as possible in a
snap. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Am I completely mistaken on this? A
barrel roll is easy to detect. An axial roll is easy to detect.
If it is not a barrel roll, and not an axial roll, then it must be a valid
snap, even if it is subtle and the plane is not buried deeply in a
snap. At least that is my current understanding.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'll admit that I don't really understand
the degree at which the plane must "break" in the direction of
snap. Who came up with that idea? What really does that mean,
and how do you measure it? "the nose of the fuselage should show a
definite break in the direction of the snap". Ok, what is
definite? At what point exactly must the aircraft become
stalled? It takes time for the control surfaces to deflect. It
does not happen instantaneously. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think the maneuver is over described and over
analyzed. Its a "rapid autorotation in the pitch, yaw, and roll axes
of flight in a stalled wing attitude." That should be good enough to
judge it. If not, maybe use my definition of judging it.
</FONT><FONT face=Arial size=2>Until I know what a "definite break" is,
that's what I am going to do.</FONT></DIV>
