[NSRCA-discussion] [F3A-Discussion] snaps

[Troy Newman]

Ken,

 

It still has to stay on flight path

 

"Snap rolls have the same judging criteria as axial rolls as far as
start and stop of the rotation, and constant flight path through the
manoeuvre is concerned."

 

 

As Matt suggested this is not a discussion on we think it should be,
rather it is how the rule is written

Glad for that description...the way I originally understood it the plane
was not supposed to deviate from the flight path...always said that was
impossible...

	Yes that is correct, thanks Matt.

	The F3A maneuver description may be inadequate and/or
inaccurate, however that doesn't much matter for the judge who has the
ardeous task of deciphering the snap. The description stands as is for
this cycle and that's how the World's judges will judge them to the best
of their ability next year. I urge all judges that judge F3A Semis and
Finals at this year's Nats/Team Selection contest to take heed of FAI
description (not AMA) and judge accordingly.

	 

	In essence, Snaps should not zeroe'd as easily as they once
were; far cry from where it was just a couple years ago. I believe
that's the main reason the rule was written as indicated. 

	 

	Mike's point I think deals with bringing the Snap back out of
hibernation such that folks get a chance to re-read it and re-hash just
in time for the Team Selection; fresh in one's mind so to speak

	Mike, I'm replying from a blackberry without the benefit of the
rulebook in front of me. I thought these were called "Flick Rolls" now?
I don't think any of us are equipped in the context of judging a 0.5
second manuever to determine if is "stalled" or "unstalled." I think
Jerry Budd posted on the nsrca list the last dissertation on snaps,
which from memory, pretty much proved the planes are not stalled.
	
	Given you posted this, what do you want to see happen? Thx Jim
W.

	Given the abundance of snap maneuvers(7 maneuvers, 9 snaps) in
the F-11 pattern, I feel compelled to give the exact description via the
F3A rulebook:

	 

	A snap-roll is a rapid autorotative roll where the model
aircraft is in a stalled attitude, with a continuous high angle of
attack.

	 

	Snap rolls have the same judging criteria as axial rolls as far
as start and stop of the rotation, and constant flight path through the
manoeuvre is concerned.

	 

	At the start of a snap-roll, the fuselage attitude must show a
definite break and separation from the flight path, before the rotation
is started, since the model aircraft is supposed to be I a stalled
condition throughout the maneuver.  If the stall/break does not occur
and the model aircraft barrel-rolls around, the manoeuvre must be
severely downgraded(more than 5 points).  Similarly, axial rolls
disguised as snap-rolls must be severely downgraded(more than 5 points)

	 

	Snap-rolls can be flown both positive and negative, and the same
criteria apply.  The attitude(positive or negative) is at the
competitors discretion.  If the model aircraft returns to an unstalled
condition during the snap-roll, the manoeuvre is severely downgraded
using the 1 point/15 degree rule.
