<br><font size=2 face="sans-serif">On the tail wiggle. The Advanced negative snap 45 down has a tendency to pick up speed and produced a very rapid snap (hey-somehow I think you know this but gotta go through it for those that do not know how famous you are). Anyway-as a result I see alot of what looks like what you describe as the rapid roll with a tail waggle (much more descriptive than wiggle which infers that it keeps going then fizzles out). So when I mentioned the famous line "That was not a snap" a person's response to me was, yes it was because with aileron alone the plane cannot roll that fast-therefore it is a snap- just very rapid. Kinda made sense at the time....All the elements where there, just in a micro second.....Then I was told that the pilot must snap so that the judges can see it...so then that was a zero.....basically cuz it was too fats to discern all the elements.</font>
<br>
<br><font size=2 face="sans-serif">So, me as a pilot., I am trying to make it as to be seen, but I also noticed that the guys with the fast aileron roll tail waggles never get ZEROs even at the NATS or even from me. And in a moment of mental panic that type of snap is my back-up (i.e. mechanical snap). What are your thoughts on this???? Please do not tell me to take up golf instead or stick to flying sport semi-scale P-51s.<br>

<br><font size=2 color=#000080 face="Arial">Visually, there is a range of snaps that look good and are OK. There is a barrel-roll which obviously blows out, versus a tight snap. Easiest zero to handout. In the blink of an eye, easy to identify as barrel-roll and zero. An impression is left instantly that says, "that is not a snap."</font>
<br><font size=2 color=#000080 face="Arial"> </font>
<br><font size=2 color=#000080 face="Arial">I think the problem judging is determining the difference between a tight fast snap, and an ultra fast aileron roll with a tail wiggle. Not easy to determine. This may sound simple, but if I have to think twice about weather it was a great looking tight snap, or a fast aileron tail wiggle, it gets a downgrade and not a zero. The speed change is a big help to me. If I can see a speed change, it helps to determine it a snap. If the maneuver is flown through with no speed change, it is harder to call a snap. </font>

<br><font size=3 face="Times New Roman"> Steve I agree with you. Now how do we get everyone on the same page? Even the judges at the Worlds disagreed on this. When I'm judging and flying I know a good snap from a bad one but I'll be damned if I can explain it. I just feel I know it. Mike<br>
