<DIV>Can't really do that Bobby. The Snap itself is but an element in a larger
maneuver. </DIV>
<DIV> </DIV>
<DIV>"Yaw Induced displacement in flight path" OR Lateral displacement in flight
path" is better verbiage, I agree. That's what was meant</DIV>

<DIV>Good suggestion, Matt. But I think it's important to clarify and
differentiate "Yaw" displacement (which I interpret as angular deviation in
yaw) form "Track displacement" (which I propose to be the overall "sideways"
shift of the track of the CG that occurs as a result of the snap).</DIV>
<DIV> To me, those are two different animals; I say NO
angular yaw offset permitted, but lateral TRACK displacement okay...up to how
much may be a hair to split by those so inclined.</DIV>
<DIV> </DIV>
<DIV>Personally, I think we change the Snap scoring to 0 or 10, and be done
with it.</DIV>

<DIV>I agree Ed, snaps are not that hard to define. And it isn't hard to
describe the judging. Several of us (Dean, Dave and Earl to name 3) have
tried to do exactly that and all have done a pretty good job. </DIV>
<DIV> </DIV>
<DIV>What has been hard, at least the last three times the Snap subject has
come up, is to get consensus. Well, forget consensus, try common ground.
</DIV>
<DIV> </DIV>
<DIV>Let's take a different approach and try to add to the existing
description. The existing description includes the following,:</DIV>
<DIV>1- starts with definite break in pitch attitude.</DIV>
<DIV>2- stalled maneuver</DIV>
<DIV>3- tail inscribes cone</DIV>
<DIV>4- CG continues on same flight path as prior to entry.</DIV>
<DIV>5- there are several rulebook things that will zero the maneuver</DIV>
<DIV> </DIV>
<DIV>Now for some adders:</DIV>
<DIV>1- should any displacement in yaw be allowed before downgrading? How
much displacement? Personally I think less than half wingspan (3 feet) is
reasonable buffer. (Forget about design differences in Pattern. It's a
thorougbred event and designers should have all parameters optimized)</DIV>
<DIV>2- how much displacemnt in pitch should be allowed before
downgrading? Again I think less than half wing span (3 feet) is
reasonable</DIV>
<DIV>3- how about snap rate? slower, more graceful vs faster, more
violent snap- should it be a judged criterion? I believe that fast
snaps and slow snaps should have equal footing.</DIV>
<DIV> </DIV>
<DIV>Not specifically an adder per se', what about KFactro for these
maneuver types, as Ron suggested earlier? Personally, I don't think a change
is warranted but is worth looking into to see where folks stand.</DIV>
<DIV> </DIV>
<DIV>I challenge all who wrote to the earlier thread, to put their creative
caps back on and help nail down the snap's description more definitely.
Add to my list or start your own. Then lets put it all together and propose
it to the Contest Board. IF it passes, then help spread the word to all who
are not online.</DIV>
