interesting, indeed. I was judging at a large IMAC contest a few
years ago, when (apparently) the chief judge felt the competitors were
fudging the snaps,somehow.(?) So., the competitors starting making
the breaks very obvious, to prevent downgrades. You never in
your life saw such ugly snaps. Fuselage angles went from level to an
immediate (up to) a 45 degree angle. But, the breaks were certainly
obvious; they couldn't be missed. In fact, it seemed to me the
breaks were the dominant feature of the maneuver. Again:
really, really ugly.</SPAN><SPAN

what this goes back to is the erroneous belief that you need to see an
exaggerated pitch departure or it should be severely downgraded.
Keep reading the maneuver description. It needs "A" pitch break,
and depending on the current aoa (angle of attack) that can be a
difference of just a degree or 2 if you are near the critical aoa.
Please don't tell me guys, you are looking for MORE than a simple
exceeding of the critical aoa and resulting stall. An exaggerated
pitch break just to prove to naysayers that you make a break is wrong,
wrong, wrong. It says it needs "A" break. Please keep
re-reading it. Same for spin entry. It needs to stall, not
go 30 degrees nose up to "prove" a stall. We are getting wound up
over a misunderstanding of the mechanics of a stalled condition.
As Don and Verne are alluding to, it really is not that
complicated.<BR><BR>Chris<BR><BR><A

The attitude <o:p></o:p></PRE><PRE>(positive or negative) is at the competitor’s discretion. If the model aircraft returns to an unstalled <o:p></o:p></PRE><PRE>condition during the snap-roll, the manoeuvre is severely downgraded using the 1 point/15 degree <o:p></o:p></PRE><PRE>rule. <o:p></o:p></PRE><PRE> <o:p></o:p></PRE><PRE>AMA: <o:p></o:p></PRE><PRE>Snaps: A Snap roll is a simultaneous, rapid autorotation in the pitch, yaw and roll axes of flight in a stalled wing attitude. The following criteria apply: <o:p></o:p></PRE><PRE>1. Since the maneuver is defined as a stalled maneuver, initiated by a stall of the wing induced by a rapid change in pitch attitude, the nose of the fuselage must show a definite break in pitch attitude from the flight path in the direction of the snap (positive or negative) while the track closely maintains the flight path. The lack of a discernable pitch break is downgraded by 5 points. Large deviations from the flight path, indicative of a delayed stall, are to be downgraded using the 1 point per 15-degree rule for each axis of the excursion before stall. For example, it the model pitches 15 degrees nose up and the wings rotate 15 degrees before the stall, the maneuver should be downgraded 1 point for pitch and 1 point for roll. <o:p></o:p></PRE><PRE>2. The track visualized as the path of the Center of Gravity (CG) should closely follow the geometric flight path of the maneuver while the nose and tail auto rotate through opposite helical arcs around the flight path. Lack of these helical arcs (or coning) is indicative of an axial roll and is scored zero. <o:p></o:p></PRE><PRE>3. If a stall does not occur and the model barrel rolls, the score is zero. A barrel roll can be identified when the CG, the nose, and tails scribe the same helical path through the required rotation of the maneuver <o:p></o:p></PRE><PRE>4. Snap rolls have the same judging criteria as axial rolls as far as start and stop of rotation, constant flight path through the maneuver and centering on lines. <o:p></o:p></PRE><PRE>5. If the model returns to an unstalled condition during the maneuver, such that the autorotation is not visible and the model rolls or barrel rolls to complete the maneuver, it would be downgraded using the 1 point per 15 degree rule. <o:p></o:p></PRE><PRE>6. Airspeed is not a criteria which should be used to judge this maneuver. The wing of the model is stalled during this maneuver; therefore a significant decrease in speed may occur and is not a cause for downgrade. <o:p></o:p></PRE><PRE><o:p> </o:p></PRE><PRE><o:p> </o:p></PRE><PRE>Vicente "Vince" Bortone <o:p></o:p></PRE><PRE><o:p> </o:p></PRE><PRE>----- Original Message ----- <o:p></o:p></PRE><PRE>From: "Matthew Frederick" <A href="mailto:mjfrederick@cox.net"><mjfrederick@cox.net></A> <o:p></o:p></PRE><PRE>To: "General pattern discussion" < nsrca -discussion@lists. nsrca .org> <o:p></o:p></PRE><PRE>Sent: Tuesday, October 13, 2009 9:47:30 AM GMT -06:00 US/Canada Central <o:p></o:p></PRE><PRE>Subject: Re: [NSRCA-discussion] How I became an expert Snap Judge (TIC) <o:p></o:p></PRE><PRE><o:p> </o:p></PRE><PRE>? <o:p></o:p></PRE><PRE>While speaking with Don Ramsey about the nuances of judging snaps at a recent contest I found that he agreed with my interpretation of the FAI snap rule. The severe downgrade should only be applied if there is no break AND there is no autorotation (this is exactly what the rule says). Basically, lack of a break is not substantial grounds for the severe downgrade in FAI . If the break is not seen and autorotation still occurs at some point during the roll the one point per 15 degree rule applies. Since the snaps happen so fast, for me it's usually not more than 1 or 2 points unless it was blatantly obvious that the plane rotated a while before the snap truly began. It's the same as if you stop the snap before completing the rotation and do an axial roll to finish. This nonsense of people being so quick to apply a severe downgrade has gone too far. One element of a maneuver (because I can't think of any sequence that has just a snap roll) should not ruin a whole flight, or eve<o:p></o:p></PRE><PRE>n that one maneuver unless it just wasn't a snap. I like the idea of "if it's not a barrell roll and not an axial roll, it's probably a snap." <o:p></o:p></PRE><PRE> <o:p></o:p></PRE><PRE>Matt <o:p></o:p></PRE><PRE>----- Original Message ----- <o:p></o:p></PRE><PRE>From: Vicente <A href="mailto:vicenterc@comcast.net"><mailto:vicenterc@comcast.net></A> "Vince" Bortone <o:p></o:p></PRE><PRE>To: General pattern discussion <mailto: nsrca -discussion@lists. nsrca .org> <o:p></o:p></PRE><PRE>Sent: Monday, October 12, 2009 5:12 PM <o:p></o:p></PRE><PRE>Subject: Re: [NSRCA-discussion] How I became an expert Snap Judge (TIC) <o:p></o:p></PRE><PRE> <o:p></o:p></PRE><PRE>I believe that the current downgrade is severe.
