<DIV><FONT face=Arial size=2>More than 1 pilot was awarded 1 or more zeros
in the 2004 US NATs F3A final on snap maneuvers. The "average" snap in

any break / displacement is infinitely more compared to none,

<DIV><FONT face=Arial size=2>A stalled entry is a required element of spins - no
stalled entry, score equals zero. No different for snaps.
Judges are required to judge what they actually see (not what they think

complete all required elements to avoid downgrades (which may be a downgrade to
zero).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>To specifically answer Bob's question - my opinion
- if the geometry of the manuever is not compromised, then no

<DIV><FONT face=Arial size=2>Another question(s) - In a given maneuver involving

rolls (was Why is it so quiet?)</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Good topic Bob. If the model really did a
snap roll, it had to displace somewhat. If not, and if you could
actually tell that it did not, that could be an indicator that a snap
roll did not actually happen. Generally, the model has to displace to a new
track, however slight, from the yawing and pitching moments
introduced. The criteria should perhaps be that you are able to able to
maintain the new track exactly in parallel to the pre-snap track. How
much offset is OK is hard to say, but things generally start looking
suspicious whan it's much more than a couple of wingspans. You would
generally start to see other obvious problems, such as barrel rolling, if the
displacement were really large. For another perspective, I think the
Scale Aerobatics Flying and Judging Guide does a decent job of
describing how to grade a snap.</FONT></DIV>

<DIV><FONT face=Arial size=2>Ya well, it's definitely not going on the
primary bird. For that I have a trusty OS 160FX with vp30 pump. I know it
will run when I want it to run.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Just like me "testing" a new design, testing
my feather cut, testing my composite skillz (or lack of), so far so good.
Of course I didn't make the YS, so that one is more of a massochistic
tendancy methinks. I'm not skeert to spend a buck. Plus it wouldn't take
too much to drop in an OS if it comes to it. I've gotta see for myself if
the fire is as hot as it looks. I usually suffer 3rd degree burns right
after one of these moments.</FONT></DIV>
